timama [110]2 years ago
5 0

Step-by-step explanation:

The answer is the third one where x=6 and y= -4

Explanation:

Replace x and y with 6 and -4, so it becomes

2(6) = -5(-4) - 8

Then solve. 2×6 is 12 and -5×(-4) is 20, since two negatives make a positive. Then bring down -8

12 = 20 - 8

12 = 12

5x-3-2x/7=24 solve for x
bearhunter [10]

Answer:

X=5.7

Step-by-step explanation:

5x-3-2x/7=24

We simplify the equation to the form, which is simple to understand  

5x-3-2x/7=24

Simplifying:

5x-3-0.285714285714x=24

We move all terms containing x to the left and all other terms to the right.  

+5x-0.285714285714x=+24+3

We simplify left and right side of the equation.  

+4.71428571429x=+27

We divide both sides of the equation by 4.71428571429 to get x.  

x=5.72727272727

I don’t understand this subject at all if you wold answer that would be a big help
Digiron [165]

Answer:

d= 8.6 ft

Step-by-step explanation:

In similar triangles, the corresponding sides are in proportion.

\boxed{\dfrac{AW}{MZ}=\dfrac{AJ}{MJ}=\dfrac{WJ}{ZJ}}

To find the value of x,

\dfrac{AJ}{MJ}=\dfrac{WJ}{ZJ}\\\\\\\dfrac{6}{7}=\dfrac{d}{10}\\\\\\\dfrac{6}{7}*10=d

d = 8.6 ft
