Does anyone know 1/4 x ? = -2?
SSSSS [86.1K]

Answer:

-8

Step-by-step explanation:

1/4 x = -2

You want the value of x. x is being multiplied by 1/4. To get x alone on the left side, you need to divide both sides by 1/4. Dividing by 1/4 is the same as multiplying by 4.

Multiply both sides of the equation by 4.

4 * 1/4 x = -2 * 4

4 * 1/4 = 1, so on the left side you get 1x which is just x.

x = 8

Answer: -8

Find the missing b for a trapezoid with a=68, h=4, b=21
MAVERICK [17]

We will have to use the formula for the area of a trapezoid on this problem, which is (b_1 and b_2 are the bases of the trapezoid and h is the height):

\dfrac{b_1 + b_2}{2} \cdot h


All we need to do is substitute the information we are given into our formula:

\dfrac{21 + b_2}{2} \cdot 4 = 68


Now, let's just simplify the equation:

\dfrac{21 + b_2}{2} \cdot 4 = 68

\dfrac{21 + b_2}{2} = 17

21 + b_2 = 34

b_2 = 13


The missing base has a length of 13 units.

If x^2 = a and a > 0. what is x?
7nadin3 [17]

\\ \sf\longmapsto x^2=a

\\ \sf\longmapsto x=\sqrt{a}

Now if a be 1,2,3,4....

\\ \sf\longmapsto x=\sqrt{1}=1

\\ \sf\longmapsto x=\sqrt{2}

\\ \sf\longmapsto x=\sqrt{3}

\\ \sf\longmapsto x=\sqrt{4}=2

And so on

Raymond works in an electronics store and gets a 12 percent employee discount. The original cost of a video game system is $175.
slava [35]

Answer:

A. $154.00

Step-by-Step Explanation:

Okay so, the first step is to get 12% and move the decimal to the left twice like this:

.12

Then, multiply 175 by .12 like this:

175 * .12 = 21

Lastly, subtract 21 from 175 like this:

175 - 21 = $154
