6.25=r2
Divide both sides by 2
3.125=r2/2
2'a cancel out
3.125=r

The opposite of multiplication is division, so you divide 2 from both sides. R2/2 = cancel out 6.25/2 = 3.125 R = 3.125

10(a-2.5+0.56b) is this equivalent to 10a - 25+56b

kirill115 [55]

Hey there!

10(a - 2.5 + 0.56b)

= 10(a) + 10(-2.5) + 10(0.56b)

= 10a - 25 + 5.6b

= 10a + 5.6b - 25

Therefore, your answer is: 10a + 5.6b - 25

Good luck on your assignment and enjoy your day!

Simplify the following expression. 1/4 (24-16x) a. 6+4x b. 6+4 c. 6-4x d. 6-4

adoni [48]

Answer is 6-4x

1/4 evaluates to 1/4

Multiply x and 16

Multiply x and 1

after you have the answer it should come out to 24-16x then multiply 1/4 * 24-16x

1/4 *24=6

1/4*(24-16*x) evaluates to 6-4x

Answer: 66 degrees

Explanation:

Check out the attached image below. Figure 1 is the original image without any additions or alterations. Then in figure 2, I extend segment BC to form a line going infinitely in both directions. This line crosses segment DE at point F as shown in the second figure.

Note how angles ABC and DFC are alternate interior angles. Because AB is parallel to DE (given by the arrow markers) this means angle DFC is also 24 degrees

Focus on triangle DFC. This is a right triangle. The 90 degree angle is at C.

So we know that the acute angles x and 24 are complementary. They add to 90. Solve for x

x+24 = 90

x+24-24 = 90-24

x = 66

That is why angle CDE is 66 degrees
