Step-by-step explanation:
the sum of elements does not change, no matter the order.
The answer is 15x + 15
Each person needs to pay x dollars per hour, and also 3 dollars for a helmet
Let us convert this into a pseudo-expression:
1 person = (x dollars) x (y hours) + 3 dollars
Now, it says that there are 5 people, so we need to multiply both sides by 5
5 people = 5 x (x dollars) x (yhours) + 3 x 5 dollars
Furthermore, it says that each person wants to go horseback riding for 3 hours:
5 people = 5(x dollars) x (3 hours) + 15 dollars
Now, we just need to convert this into an expression
5 people = 5(x)(3) + 15
5 people = 15x+15
They want the expression for cost, so we just need to give them
15x + 15
False, because it would no longer be 18 alone because of the disturbutive property.
I have these same questions but the way i solved them i did
A: 1/3 x 3.14 x 2*2 x 8 = 32/3 = 2000 divided by 32 = 63 scoops
The formula is 1/3 x 3.14 x r*2 x h
B: 1/3 x 3.14 x 8*2 x 8 = 128/3 = 2000 divided by 128 = 16 scoops
He has 11 quarters and 16 dimes
25*11 is 275 + 170 is 435.
