.25a + .5 = 4.5
.25a = 4.5 -.5
.25a= 4
a= 4÷.25
a= 16
Answer:
Non
Step-by-step explanation:
Answer:
13.5
Step-by-step explanation:
7 1/2=7.5
7.5/5*9=13.5
We can focus on each part separately, first the numbers:
-3 times (5 squared)
-3 times 25
= -75
This rules out the last two options
Next let’s focus on the x terms:
x^3 times (x^5 squared)
When raising a term that is already raised to a power by another power, you multiply the powers, in this case 5 times 2 = 10
x^3 times x^10
When multiplying numbers with the same base, you add the powers
=x^13
So the answer must be B but we can check the y terms just to make sure
y^2 times (y^4 squared)
y^2 times y^8
=y^10 which matches answer B
You will get back in change $30.24.
