Answer:
6(x + 4) = 5
Step-by-step explanation:
We can break this sentence down into individual operations:
"six times" → this means 6 multiplied by some quantity
6 · ()
"the sum of a number and 4" → this is the quantity that we can put inside the parentheses (Note that "a number" is represented as a variable x, and a "sum" is the result of the addition of multiple numbers.)
6 · (x + 4)
"equals 5" → this is self-explanatory; the expression above is equal to 5
6(x + 4) = 5
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
Note that multiplication with a value inside parentheses is implied.
For example,
4(5) = 4 · 5 = 20
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
We can solve for x in this equation to solve for "a number".
6(x + 4) = 5
↓ applying the distributive property ... a(b + c) = (a · b) + (a · c)
6x + (6 · 4) = 5
↓ simplifying
6x + 24 = 5
↓ subtracting 24 from both sides
6x = -19
↓ dividing both sides by 6
x = -19/6

A bookstore manager marks down the price of older hardcover books, which originally sell for b dollars, by 36%.
What is the sale price of a hardcover book for which the original retail price was $36.00?
The sale price is $____
THE EQUATION IS b-0.36b
Answer:
$31.02
Step-by-step explanation:
Find the amount of the discount:
47 x 0.34 = 15.98
Subtract the discount from the original price:
47 - 15.98 = 31.02

Leslie analyzed the graph to determine if the function it represents is linear or non-linear. First she found three points on the graph to be (–1, –4), (0, -3), and (2, 5). Next, she determined the rate of change between the points (–1, –4) and (0, -3) to be StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction = StartFraction 1 Over 1 EndFraction = 1. and the rate of change between the points (0, -3) and (2, 5) to be StartFraction 5 minus (negative 3) Over 2 minus 0 EndFraction = StartFraction 8 Over 2 EndFraction = 4. Finally, she concluded that since the rate of change is not constant, the function must be linear. Why is Leslie wrong? The points (–1, –4), (0, –3), and (2, 5) are not all on the graph. The expressions StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction and StartFraction negative 3 minus (negative 5) Over 2 minus 0 EndFraction both equal 1. She miscalculated the rates of change. Her conclusion is wrong. If the rate of change is not constant, then the function cannot be linear.
Answer: Slopes are not equal so the function is not linear
Step-by-step explanation:
Slope is change in y/ change in x = y2-y1/ x2-x1
Calculations for (-1, -4) and (0, -3)
slope = -3- -4/0- -1 = 1/1 = 1
Next Calculate the slope between (0,-3) and (2,5)
slope = 5--3/2-0 =8/2=4
Slopes are not equal so the the points are not linear
l 5-x l+6=5
Would it be no solution?
Answer:
x=6
Step-by-step explanation:
or,5-x+6=5
or,11-x=5
or,11-5=x
or,x=6
Answer:
No solution
Step-by-step explanation:
Yes: no solution.
Why: look what happens if you subtract 6 from both sides: you get:
| 5-x l=5 - 6 = -1
The absolute value function is never less than 0, so there is no x value that makes | 5- x l= -1 true.

Solve.
6x + 9 = -12
Don't add spaces to your answer.
Answer:
x=−7/2
Step-by-step explanation:
Answer:
x = - \(\frac{7}{2}\)
Step-by-step explanation:
6x + 9 = - 12 ( subtract 9 from both sides )
6x = - 21 ( divide both sides by 6 )
x = \(\frac{-21}{6}\) = - \(\frac{7}{2}\) ( = - 3.5 )

tom drives at a constant rate of 40 miles per hour for 3 hours.how far will he travel at that time?
A.350 mi.
B.220 mi.
C.120 mi.
D. 60 mi.
Answer: C. 120 mi.
Step-by-step explanation:
To get the answer C you take the constant rate which is 40 and multiply it by the amount of hours which is 3. Hope this helps!
Answer:
C. 120 mi.
Step-by-step explanation:
If he is constantly going 40 miles per hour. That means every hour, he goes 40 miles. So if he drives 3 hours, he would drive 120 miles because 40 miles +40 miles+40 miles=120 miles. Aka 40 times 3 to get 120 miles.

Natasha had d dollars. She bought 2 ice creams which cost x dollars each. How much money does she have left?
Answer:
d-2x
Step-by-step explanation:
d is the amount of dollars she had, 2x is the amount of money she used to buy ice creams.
We can write an equation to resemble the problem.
We can write "2x" since she bought 2 ice creams and the price of each is unknown.
We can subtract that by "d" to find how much money she has left.
Put everything together.
2x - d
Best of Luck!
Help me please I’ll give brainlest
Answer:
-17
Step-by-step explanation:
1) rewrite: (3 - n) divided by 2 = 10
2) Multiply both sides: (3-n)/ 2 = 10
3) move constant to the right: 3 - n = 20
4) calculate: -n = 20 - 3 then, -n = 17
5) change signs: n = -17
Hope this helped and wasn’t confusing, good luck! :)

3) Under very specific instructions, a jeweler made one ring for the queen and one ring for the princess. The gem on the queen's ring weighed 1/2 of a carat and the stone on the princess's ring weighed 1/4 of a carat. How much heavier was the stone on the queen's ring than the stone on the princess's?
4) Under very specific instructions, a jeweler made one ring for the queen and one ring for the princess. The gem on the queen's ring weighed 1/2 of a carat and the stone on the princess's ring weighed 1/4 of a carat. How much heavier was the stone on the queen's ring than the stone on the princess's?
5) Starting from scratch, Jasper finished 5/12 of a reading assignment Monday afternoon and another 1/2 of it on Tuesday afternoon. What fraction of the reading assignment was done by Tuesday night?
Step-by-step explanation:
1) butter = 9/10
sugar = 1/5 =2/10
butter - sugar = 9/10 - 2/10 = 7/10 =0.7 = 70%
2)
Jan = 1/2
Feb = 5/12
total = 1/2 + 5/12 = 6/12 + 5/12 = 11/12
3)
queen's ring = 1/2 = 2/4
princess's ring = 1/4
queen's ring - princess's ring = 2/4 - 1/4 = 1/4
4)same with 3)
5)
mon = 5/12
tues = 1/2 = 6/12
total = 5/12 + 6/12 = 11/12

Find the value for x.
Answer:
x = 19
Step-by-step explanation:
5x = 3x +38
that means 2x = 38
x = 19
Answer:
x=19
Step-by-step explanation:
(3x+38)°=5x°(corresponding angles)
3x°+38°=5x°
38°=5x°-3x°
38°=2x°
38°/2°=2X°/2°

What type of graph is best to use to show changes over time? A. bar graph B. line graph C. histogram D. circle graph
(will give brainliest if correct)
Answer: B
The best type of graph to show changes over time is a line graph. A line graph is ideal for displaying trends and variations in data over a continuous period. It consists of a series of data points connected by line segments, allowing for a clear visualization of how values change over time. Bar graphs, histograms, and circle graphs are better suited for other types of data analysis, such as comparing categories or showing proportions.

How did you decide where to place your line of best fit? Describe your reasoning.
Based on your data, describe the relationship between age and the number of U.S. states a person can name in 60 seconds.
Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.
Trolls will be reported
Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.
So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)
