Answer:
3 3/5 gallons per hour
Step-by-step explanation:
3/5 times 6 equals 18/5
18/5=3 3/5
<span>7x-4y=-7
5x+y=22
multiply 4 on the 2nd equation
</span>20x+ 4y=88
now you have
7x -4y = -7
20x + 4y = 88
--------------------add
27x = 81
x = 3
7x-4y=-7
7(3)-4y=-7
-4y = -28
y = 7
answer (3, 7) is the solution
I'm assuming it would be the same shape? That's also assuming that it's referring to congruent shapes and angles.
44-2x=x-10
subtract 44 from both sides
-2x= x-54
subtract x from both sides
-3x= -54
divide by -3
x= 18
square root of 18= 4.24
in radical form 3 square root of 2
hope this helps
Answer:
- Family 1: $1.850
- Family 2: $1.350
Step-by-step explanation:
We know that the total monthly payment is 3200, so if we call Pa (family A`s payment) and Pb (Family B's payment) the payments:
- Pa+Pb=3200
- also, Pa = Pb+500
So if we replace Pa in the first ecuation:
- Pb+500+Pb=3200
- 2Pb= 3200-500
- Pb=2700/2= $1.350
then Pa+Pb=3200 => Pa= 3200-1350= $1.850
Good Luck!
