Cathy pasted 5 leaves on each picture she made. She used 10 leaves in all.
How many pictures did Cathy make?

2 pictures

Step-by-step explanation: On each picture she put 5 leaves, so 5 leaves per picture. She used 10 leaves. 1=5 2=10. Basically 5•2=10

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
