Answer: Alejandra gave $60 to the cashier.
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given.
We have to subtract to the amount that Alejandra paid(x) the sum of the costs of each product [videogame (24), controller (13) and memory card (169] and the total tax (3). the expression must be equal to the amount received in change.
Mathematically speaking:
x -(24+13+16+3) = 4
Solving for x:
x - 56 =4
x = 4+56
x =60
Alejandra gave $60 to the cashier.

120 - 36 as a product with the GCF as a factor. True, we can factor out the GCF and we'll have a product:
GCF(120,36) = GCF(5(24),36)=GCF(5(12)(2),12(3)) = 12
We can factor that out and get:
120 - 36 = 12(10 - 3) = 12(7)
Answer: TRUE
How to find the GCF of three numbers.
There are a couple different ways; the obvious way is to find the GCF of the first two and then then GCF of the result and the third.
The other way is to prime factorize all three numbers; for each prime factor count how many times it occurs in each input. In the GCF it will occur the minimum of those three. Multiply the resulting powers of prime factors to get the GCF.
GCF(60,90) = GCF(30(2), 30(3)) = 30
60 + 90 = 30(2 + 3)
Xiao missed a factor of ten in the GCF.
Since is addition you do the opposite and subtract 12 from 12 and -5 then 12 cancels out and -5-12=-17
Answer: 6,160,000 db
Step-by-step explanation:
The sound of a jet engine is 70,000 times louder than that of a lawn mower.
Since we know the sound of a lawnmower, we can multiply that by 70,000 to find the sound of a jet engine:
= Sound of lawnmower * 70,000
= 88 * 70,000
= 6,160,000 db
