Step-by-step explanation:
2x + 7x - 10 = 180° because these rwo angles are supplementary
10x - 10 = 180°
10x = 190° divide both sides by 10
x = 19
measure of angle on the right:
8x - 10 ➡ 8 × 19 - 10 = 142°
measure of angle on the left:
2x ➡ 2 × 19 = 38°
Answer:
41 cookies in the box are not sugar cookies
Step-by-step explanation:
First, find what percentage of the total cookies <u>aren't</u> sugar cookies. If 18% are, then the amount that aren't is:
100% - 18% = 82%
Since 82% of the cookies aren't sugar cookies, multiply 82% by 50 to find the amount of cookies that aren't sugar cookies:
50 * 82% = 41
Step-by-step explanation:
so, if I understand correctly, then she bought 12 kg of mixed fruits.
4 kg and 500 g are apples.
you remember that the word "kilo" means 1000.
so, the apples actually weigh 4500 g or 4.5 kg.
1 kg and 75 g are oranges. that are 1075 g or 1.075 kg.
to calculate the rest (for the grapes) we best convert also the total weight into g : 12,000 g
weight grapes = 12000 - 4500 - 1075 = 6,425 g = 6 kg and 425 g = 6.425 kg
