PLEASE HELP ME SOLVE FOR X

Mathematics
1 answer:
Kitty [74]3 years ago
5 0

Answer:

7. x = 10

8. x = 13

9. x = 17

10. x = 5

11. x = 9

12. x = 11

Step-by-step explanation:

Explanation for Number 7.

The exterior angle is always equl to the sum of the two opposite interior angles.

The two opposite interior angles: 62 and (7x + 14)

The exterior angle: (15x - 4)

So you would set it up like _____ = ______ to solve for x

62 + (7x +14) = 15x - 4

62 + 7x + 14 = 15x - 4

Then move the terms

76 + 7x = 15x - 4

Collect the like terms and Calculate

7x - 15x = -4 - 76

Divide both Sides

-8x = -80

/8       /8

-x = -10

/-1    /-1

x = 10

Hope this helps ^^

I’m confused on this one
andrew-mc [135]

First we need to know the point slope form. It is y - y1 = m(x - x1). In the y1 and x1 spots, you just plug in any coordinate on the line.

m would be the slope which we already know as 5/3.

We are given the coordinate point (0,3) as a point on the line. This is also what we are going to plug into the equation. 0 will be x1 and 3 will be y1.

Our equation should then look like after plugged in as....

y - 3 = 5/3(x)

x is by itself because subtracting or adding by 0 yield the original number.

Devaughn is 8 years older than Sydney. The sum of their ages is 64. What is Sydney's age?
Zigmanuir [339]

Answer:

Sydney's age is 28

Step-by-step explanation:

Let Devaughn be D

And Sydney be S

D=S+8..... equation 1

D+S=64...... equation 2

Substitute equation 1 to equation 2

S+8+S=64

2S+8=64

2S=64-8

2S=56

S=56/2

S=28

Hope it helps

Good luck
