Answer:

5. 7(x - 2) + 1 = -34

7x - 14 + 1 = -34

7x - 13 = -34

7x = -34 + 13

7x = -21

x = -21/7 = -3

6. 10x + 4 - 8x = 2(x - 1)

2x + 4 = 2x - 2

Cancel 2x means this equation has no solution

8. 5(x - 3) + 1 = 5x - 14

5x - 15 + 1 = 5x - 14

5x - 14 = 5x - 14

5x - 5x = -14 + 14

0

9. 2x + 3 = 5x + 3 - 3x

2x + 3 = 2x + 3

2x - 2x = 3 - 3

0

11. x + 2x + 1 = 3x + 5

3x + 1 = 3x + 5

Cancel 3x means this equation has no solution

12. -3 = -2x + 4/-4

-3 × (-4) = -2x + 4

12 = -2x + 4

12 - 4 = -2x

8 = -2x

8/-2 = x

-4 = x

1. Find the length of side "a" in the figure below. Also identify the type of triangle and
Delvig [45]

Answer:

<h2>It's a right triangle. a = 5.</h2>

Step-by-step explanation:

Look at the picture.

We have the triangle 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.

We have:

a\sqrt3=5\sqrt3          <em>divide both sides by √3</em>

a=5

It's a right triangle.

Can I get help on this

88% of 300
0.88 x 300 = 364
-
24 out of 120
24 / 120 = 0.2
Move the decimal two places to the right: 20.
20%
-
3 is 12% of (unknown number)
12% × x = 3
or 12 / 100 × x = 3
Multiplying both sides by 100 and dividing both sides by 12,
we have x = 3 × (100/12)
x = 25

What is the slope of the line that contains these point?<br> (13,11),(14,6),(15,1),(16,-4)
ELEN [110]

Answer:

Step-by-step explanation:

You can easily find the slope by using two points. Let’s use (13, 11) and (14, 6)

We look at the slope equation as: y2 - y1 divided by x2 and x1.

13 = x1 11= y1 and 14= x2 6=y2

Plug in: 6-11/14-13 and solve

Answer: -5

Hope I made sense :)

damaskus [11]

Answer:

2\frac{1}{3}inches

Step-by-step explanation:

First, I would try to get the mixed numbers into improper fractions. Then, I try to make them have the same denominator so it is easier.

1\frac{1}{2}feet --- 2 inches

\frac{3}{2}feet --- 2 inches

\frac{6}{4}feet --- 2 inches

1\frac{3}{4}feet --- ? inches

\frac{7}{4}feet --- ? inches

\frac{7}{4}feet --- \frac{7}{6} × 2 inches

             = 2\frac{1}{3}inches
