Answer:
This year, Juanita will have to use $75.
Step-by-step explanation:
Because if 2 shirts is $15, 4 shirts will be $30. $45 is $15 more than $30, so the increase is $15. 2*4 is 8, so that will make it 15*4=60. 60+15=75.
Do the problem little by little:
First, -20/48 reduces to -5/12.
Next, (t^5) / (t^7) simplifies to 1 / (t^2).
Same with u^2 / u^4: 1 / u^2
v^3 / v^1 = v^2
Let's put the factors back together:
-5 * v^2
--------------------------
12 * u^2 * t^2
-5 v
This could be left as is, or shortened: ----- * [ ------- ]^2
12 t*u
(3^2)3=27
27/3^x=3
3(3^x)=27
3^x=9
x=2
Answer: not similar
Step-by-step explanation: Since only two sides are given, you cannot derive a similarity. You do not know what the third side is, and you cannot guess that the missing sides are similar
