Answer:
x = 10
Step-by-step explanation:

or, 10x + 8 = 4(2x + 7)
or, 10x + 8 = 8x + 28
or, 10x - 8x = 28 -8
or, 2x = 20
or, x = 20/2
or, x = 10
x = 10
If one angle is 8 times bigger than the other, the bigger angle's measure would be 8x and the smaller angle's measure would be x. 8x+x=90. This simplifies to 9x=90. To find x, you divide 9 from 90, making x=10. This means the smaller angle (Angle 2) is 10° and the bigger angle's (Angle 1) is 8 times 10, so it is 80°.
Answer:
The answer is 118.
Step-by-step explanation:
First we need to subtract the meal cost from average unit cost for each meal:

A restaurant profits 1.25$ for each meal. If we divide fixed cost to profit for each meal:

The restaurant have to sell 118 meals at least each day for the owner to break even
10 - 2x = -30
-2x = -40
2x = 40
x = 20
Answer:
D, 312 CM.
Step-by-step explanation:
DE/C = 60/360 = 1/6
Cross-multiplying
C = 6DE = 6 x 52 = 312 CM
