Answer:
x = 67; y = 40
Step-by-step explanation:
You are correct with y. Angles y + 23 and 63 are vertical, so they are congruent. That gives you y + 23 = 63, which gives y = 40.
To find x, look at angles 2x - 17 and 63.
They are adjacent angles whose outside rays lie on a line. Angles like these are called a linear pair, and they are supplementary. That means their measures add up to 180 deg.
2x - 17 + 63 = 180
2x + 46 = 180
2x = 134
x = 67
Answer:
one dozen: 12 servings
four dozens: 12x4 so 48 servings
Step-by-step explanation:
Assuming one cookie is one serving a dozen would be 12 so 12 servings per dozen.
Answer:
3 + 5 = 8 which is a monomial
Step-by-step explanation:
a binomial has 2 terms; example, 3y + 5
Answer:
56
Step-by-step explanation:
The ratio is 5 to 2, and we must keep it this way.
For example, if he had 10 regular sodas then the ratio would be 10:4.
If something happens to one side of this ratio, it needs to happen to the other so it remains balanced.
We need to find out how 5 got to 140. To find out, simply divide 140 by 5.
140 divided by 5 = 28
So, 5 was multiplied by 28 to get to 140.
Now, we need to multiply the 2 by 28 as well so it remains balanced.
2 x 28 = 56.
So, there are 56 diet sodas.
