Solve for y:
3 y - 2 y + 5 = 11
Grouping like terms, 3 y - 2 y + 5 = (3 y - 2 y) + 5:
(3 y - 2 y) + 5 = 11
3 y - 2 y = y:
y + 5 = 11
Subtract 5 from both sides:
y + (5 - 5) = 11 - 5
5 - 5 = 0:
y = 11 - 5
11 - 5 = 6:
Answer: | y = 6 ; thus 1 Answer
Answer:
Step-by-step explanation:
Given :
To Find : What are the factors of
Solution:
Since 100 =
using property :
Thus the factors of are (x+10) and (x-10)
The diagram tells us 3 things: the right angle and the two corresponding side measurements. Because the side measurements are corresponding, we can set a proportion:
6/9=9/15
If this proportion is true, it means the triangles are similar. If this proportion is impossible, it means the triangles are no similar.
To calculate this, we use cross multiplication.
6/9=9/15
6*15=9*9
90=81
90 does not equal 81 making this proportion impossible, which concludes that these two triangles are not similar.
I hope this helps! Please comment if you have any questions.

Answer:
13 costumes
Step-by-step explanation:
The amount of fabric used is the product of the amount per costume and the number of costumes.
A = na . . . . . A = total area; n = number of costumes; 'a' = area per costume
46 2/3 = n(3 1/2)
n = (46 2/3)/(3 1/2) = (140/3)/(7/2) = (140/3)(2/7) = 40/3 = 13 1/3
Apparently there is some waste, as Emerson used more fabric than necessary to make 13 costumes.
Any real numbers , I think
