In the isosceles trapezoid below,<br> X =<br> 5x+ 15°<br> 7x-11°
tangare [24]

Answer:

x = 13°

Step-by-step explanation:

5x+15°=7x-11°

5x-7x = -11°-15°

-2x = -26° divide both sides by -2

x = 13°

5x+15° = 5×13°+15° = 80°

7x-11° = 7×13° -11°. = 80°

Chanda can bake and decorate 72 cookies in 2.5 hours. At this rate,how long will it take her to bake and decorate 108 cookies?
In-s [12.5K]

Hello there! A. 3.75 hours is your answer.

Okay, so lets start by finding the unit rate. To find the unit rate, we can use this formula: total ÷ time = unit rate.

total (72 cookies) ÷ time (2.5 hours) = unit rate. (how many cookies she can decorate and bake in an hour)

72 ÷ 2.5 = 28.8 cookies an hour

Now that we have this information, replace the 180 cookies in for the total number and use algebra to solve.

180 cookies ÷ x time = 28.8

Since 180 is a little more than 2 times 72, A would best fit since 3.75 is much closer to 2.5 than the other options. To check this, we can place 3.75 in for x in 180 ÷ x = 28.8.

180 ÷ 3.75 = 28.8.

So, this is your correct answer.

5x + 7 - 2(-8x -1) = 7(x - 1)
love history [14]

Step-by-step explanation:

5x + 7 - 2( - 8x - 1) = 7(x - 1)  \\ 5x + 7 + 16x + 2 = 7x - 7 \\ collecting \:  like \:  \: terms \:  \\ 5x + 16x - 7x =  - 7 - 2 - 7 \\ 14x =  - 16 \\ divide \: both \: side \: by \: 14 \\  \frac{14x}{14}  =  \frac{ - 16}{14}  \\ x =   - \frac{ 8}{7}
