How to divide 33 photos into two groups so the ratio is 4 to 7
Nataliya [291]
33 photos in a 4x to 7x ratio

4x + 7x = 33
11x = 33
x = 3

33 photos can be put in a 4(3) to 7(3) ratio

which is a 12 to 21 ratio

so 12 photos on one side, and 21 on the other side to get the ratio of 4 to 7

Note:
<span>a(b) = ab = a x b = a times b</span>

I hope I’m correct but correct me if I’m wrong is this complementary?
Nesterboy [21]

Answer:

Linear Pair

Step-by-step explanation:

The kind of angle formed by a and b when put together is a straight angle.

A straight angle means that a+b=180 degrees.

a and b are supplementary.

They are also a linear pair since they are already put together. Meaning, they share a common vertex and a common side while forming a straight angle together.

They aren't complementary because the angles exceed 90 degrees when added together. Complementary angles should add up to 90 degrees exactly.

They aren't vertical angles because they don't happen across from each other in two intersecting lines. (Note: Vertical angles are also congruent.)

They aren't alternate interior because they don't even happen at two different intersections. So we would definitely not go to to that, alternate exterior, same side interior, same exterior, or corresponding angles. Because all of these require the angles to happen at two different intersections.

How do I do GCF (greatest common factor on -5y - 35? I need help because I am not good at it.
ICE Princess25 [194]

Answer:

-5(y+7)

Step-by-step explanation:

Well, the numbers you can divide 5 with are 1 and 5.

35 divides both with 1 and 5 too, but since 5 is the greatest, you choose 5.

so,

you divide both with -5, since both are negative.

-5y/-5 = y

-35/-5 = 7

so,

-5(y+7)

check:

-5*y = -5y

-5*7 = -35

so,

-5y-35, that's true.
