use the numbers -4, -1, 3/2, or 2/3 to write an expression that is less than -4

Answer:

22.4

Step-by-step explanation:

Answer:

I believe the answer is 20ft

Step-by-step explanation:

Because the difference between 10 and 16 is 6 so add 6 on to 14 to make 20

so the bigger trapezoid is 4x's bigger than the smaller trapezoid.

hope this helps :)

have a great day

By proportion that is:(54/150) * 8450= 54 * 56 1/3= 3042

Answer:

By proportion that is:(54/150) * 8450= 54 * 56 1/3= 3042

Step-by-step explanation:

Answer:

Step-by-step explanation:

reason 1:

opening of brackets to solve the expression

reason 2:

in multiplication order is followed i.e. the number always lead the variable in the expression

reason 3:

for clarification brackets are added to multiply like terms i.e. numbers with numbers and variable with the variable

reason 4:

the solved and simplified expression is delivered as a result

Answer:

b

Step-by-step explanation:

a isn't it because it multiplies 7 by 3 added with x. the second equation next to it is simply not equal to it.

b is slightly referring to a property called "the associative property of addition." the associative property of addition is simply adjusting the place of the parenthesis. per example:

(1+2)+3=1+(2+3)

either way, you still get the same answer.

c isn't it because 7*x*3 is all multiplied, as to the second equation, part of it is being added, then multiplied by 7.

d cannot be it because we do not know if x is < or > than 3.

Option (C) Infinitely many solutions

Answer:

Let u = √x which gives u2= x and rewrite the given equation in terms of u

u = 3 - u 2 / 4

Multiply all terms by 4, simplify and write the above quadratic in standard form and solve it for u.

u 2 + 4 u - 12 = 0

Two solutions: u = - 6 and u = 2

Use the substitution used above u = √x to solve for x.

u = - 6 = √x has no solution

u = 2 = √x has solution x = 4

Below is shown the graph of the right side of the given equation when written with its right side equal to zero. The x intercept of the graph is the graphical solution to the equation as shown below.

Step-by-step explanation:

Answer: x = 4

Step-by-step explanation:

    Given:

√x = 3 - (1 / 4)x

    Rewrite:

\(\displaystyle \sqrt{x} = 3 - \frac{1}{4}x\)

    Square both sides:

\(\displaystyle (\sqrt{x} )^{2} = (3 - \frac{1}{4} x)^{2}\)

\(\displaystyle x= \frac{1}{16}x^{2} -\frac{3}{2} +9\)

    Set the equation equal to 0:

\(\displaystyle \frac{-1}{16}x^{2} +\frac{5}{2} -9=0\)

    Use the quadratic formula:

\(\displaystyle x=\frac{-b\sqrt{b^{2} -4ac} }{2a}\)

\(\displaystyle x=\frac{-(\frac{5}{2})\sqrt{(\frac{5}{2})^{2} -4(\frac{-1}{16} )(-9)} }{2(\frac{-1}{16} )}\)

x = 4, 36

    Plugging back into equation shows us only one answer works,

x = 4

Answer:

f(6) = 24

Step-by-step explanation:

Simply plug the value of 6 into the equation for x.

f(x) = x^2 - 2x

f(6) = (6)^2 - 2(6)

f(6) = 36 - 12

f(6) = 24

Answer: 24

Step-by-step explanation: you can say that 6=x Wichita in this case we would substitute x for 6

6²-2*6=36-12=24

Hope this helps!

Answer:

The answer is 11.

Step-by-step explanation:

Because if you multiply 11 and 6.4 you get 70.4. Then you add 2.2 until you get 85.8.

Answer:

E. 11

Step-by-step explanation: 11 x 6.4 = 70.4 + 2.2 x 7 = 85.8

Answer:

t = 1

Step-by-step explanation:

16 - 2t = 5t + 9

1) First move 5t to the left side

16 - 2t - 5t = 9

2) Then move 16 over to the right side

-2t -5t = 9 - 16

3) simplify both sides

-7t = -7

4) divide both sides by 7

-t = -1

5) divide both sides by -1

t = 1
