Question

How many times did she deposit $5 and how many times did she deposit $3.50?

Mia made deposits of $5 and deposits of $3.50.

Answer 1

5x + 3.5y = 59.5
x + y = 14

That is our system of equations

Answer 4

Oh okay

Answer 5

the let call x number of deposits for $5
and y ......................................... for $3.5
total deposits x+y=14
5x number of deposit for $5
3.5y ....................... for $3.50
then the second equation is
5x+3.5y=59.50

substitute x with 14-y in the second equa
to find x and then find y later

x+y=14
5x+3.5y=59.50

Answer 6

If you go to www.desmos.com and put in those 2 equations, see where they intersect

Answer 7

so it is 14 ND 59.50??

Answer 8

@sleepyjess Yeah i use desmos a lot but this question was a little confusing

Answer 9

Yes, because they give us that there were 14 deposits and the deposits totaled 59.5

Answer 10

do put the zero with 59.50?

Answer 11

It doesn't matter

Answer 12

A polygon is shown:

A polygon MNOPQR is shown. The top vertex on the left is labeled M, and rest of the vertices are labeled clockwise starting from the top left vertex labeled, M. The side MN is parallel to side QR. The side MR is parallel to side PQ. The side MN is labeled as 5 units. The side QR is labeled as 7 units. The side MR is labeled as 3 units, and the side NO is labeled as 2 units.

The area of polygon MNOPQR = Area of a rectangle that is 15 square units + Area of a rectangle that is ___ square units. (Input whole numbers only, such as 8.)
