Mathematics

Schach [20]4 years ago
8 0

Answer:

m∠A = 120°

m∠C = 45°

Step-by-step explanation:

all triangle angles add up to 180

(12x + 12) + 15 + (3x +18) = 180

15x + 45 = 180

15x = 135

x = 9

m∠A = (12x + 12) = 12(9) + 12 = 120

m∠C = (3x +18) = 3(9) + 18 = 45

How do you do this?Can you help me with the steps? I don't really get this a lot
polet [3.4K]
Before you do the steps, change the fractions given to improper fractions:
2 2/3 = 8/3
3 1/6 = 19/6

Now, I think the first step they want you to write is:
8/3 (divided by) 19/6

When you divide two fractions, it's the same as multiplying the first fraction by the reciprocal of the second fraction. (A reciprocal is a fancy way of saying you flip the fraction)
So the next step will look like this:
8/3 x 6/19

With this setup, you can cross simplify the fractions so that they look like this:
8/1 x 2/19
When you multiply this, you get 16/19

When 1/8 cup of popcorn kernels are popped, they create 5 cups of popped corn. How many cups of popcorn would 1 cup of kernels p
Anon25 [30]

Answer:

D

Step-by-step explanation:

Because it is 1/8 it is much easier.

8 times 5 = 40

So you know that 1/8 was timesed by 40 to get 5. This means you can times x by 40 to get the cups of popcorn the kernels would produce. That means 1 times 40 equals 40. Making the cups of popcorn the kernels would produce is 40.
