Answer:

Step-by-step explanation:

180-150=30

angle 3 is a right angle so it equals 90

all triangles add up to 180

so 90 + 30 is 120

180-120=60

a line is 180 degrees

so the answer is 120 B

Problem of the Day:

Shtirlitz [24]

Answer:

Step-by-step explanation:

What this question is asking of you is what is the greatest common divisor of 12 and 15. Or, what is the biggest number that divides both 12 and 15.

in order to find this we have to split each number into it's prime components.

for 12 they are 2,2 and 3 (

⋅

)

and for 15 they are 3 and 5 (

⋅

)

Out of those two groups (2,2,3) and (3,5) the only thing in common is 3, so 3 is the greatest common divisor. That tells us that the greatest number of groups that can exist and have the same number of girls and the same number of boys for each group is 3.

Now to find out how many girls and boys there are going to be in each group we divide the totals by 3, so:

girls per group, and

boys per group.

(just as a thought exercise, if there were 16 boys, the divisors would have been (2,2,3) and (2,2,2,2), leaving us with 4 groups [

⋅

] of 3 girls [12/4] and 4 boys [16/4] )

What is the solution to this equation?<br> x/-4=8

guapka [62]

X=32

Explanation:
When you change sides, if in the left side you are multiplying, when you transfer it to right side you divide. Same thing should be done for addition subtraction.

So /-4 was division and negative number

When we transfered it, it became positive multiplication number

satela [25.4K]

.75 * p = 15

divide by .75

p = 15/.75 = 20

20 peaches

.15 * d = puppies

.15 * 60 = puppies

puppies = 9

stereo *.09 = 35
