Simplifying

8x + -10 = 62

Reorder the terms:

-10 + 8x = 62

Solving

-10 + 8x = 62

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '10' to each side of the equation.

-10 + 10 + 8x = 62 + 10

Combine like terms: -10 + 10 = 0

0 + 8x = 62 + 10

8x = 62 + 10

Combine like terms: 62 + 10 = 72

8x = 72

Divide each side by '8'.

x = 9

Simplifying

x = 9

Factor completely 15a^2b-10ab^2

ozzi

Find the Greatest Common Factor (GCF)

GCF = 5ab

Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

5ab(15a^b/5ab + -10ab^2/5ab)

Simplify each term in parentheses

Two supplementry angles are in the ratio of 5:7 . find the measure of the angles

Natasha2012 [34]

Answer:

75 degrees and 105 degrees

Step-by-step explanation:

Supplementary angles are those angles that sum up to 180 degrees

So angle A + B = 180 or B = 180 - A

then A/B = 5/7

7A = 5B

7A = 5(180 - A)

7A = 900 - 5A

12A = 900

A = 75

then B = 180 - A = 180 - 75 = 105

Find the area of this figure. Round your answer to the nearest hundredth. Use 3.14 to approximate Pi.

taurus [48]

Answer:

$26.13ft^2$

Step-by-step explanation:

Step 1 - As both triangles have lengths the same size, they both add together to equal a rectangle. Therefore:

4 x 3 = 12

Which is the area of the triangles.

Step 2 - Calculating the area of a circle uses the formula:

$\pi r^2$

Where r is the radius of the circle.

Plug the known variables in:

$\pi \cdot 3^2\\\pi \cdot 9\\3.14 \cdot 9 = 28.26\\$

However, this is the area of a full circle. The figure is only half a circle so we must divide this by two:

28.26 ÷ 2 = 14.13

Now, add the area of the semi-circle to the area of the triangles:

14.13 + 12 = 26.13

Therefore, the area of the figure is $26.13ft^2$ .

Hope this helps!
