Answer:
-3/2
Step-by-step explanation:
here it goes. (-1)- (2) / (5)-(3)
-1 / 7 = x
You need to combine the 2x and 5x then devise the 7x from -1
The length is 10
The width is 4
4 + 6 = 10
4 x 10 = 40
Answer:
6 quarters, 3 dimes, and 12 nickles
Step-by-step explanation:
Let's say Q is the number of quarters, D is the number of dimes, and N is the number of nickles.
From the information in the problem, we can write three equations:
25Q + 10D + 5N = 240
N = 2Q
Q = 2D
Solve the system of equations using substitution.
25(2D) + 10D + 5(2Q) = 240
50D + 10D + 10Q = 240
60D + 10(2D) = 240
60D + 20D = 240
80D = 240
D = 3
Q = 6
N = 12
There are 6 quarters, 3 dimes, and 12 nickles.
How are the two things even relevant?
