Answer:12/7
Step-by-step explanation:
-9 2/7 -(-10 3/7)
(7x-9+2)/7+10 3/7
(7x-9+2)/7+(7x10+3)/7
-61/7+73/7
(-61+73)/7=12/7
Answer:
L+C=14
10C+11L=145
Step-by-step explanation:
Let C represent Car Washing
Let L represent Landscaping
If Mila worked a total of 14 hours; then
L+C=14
If Mila earned a total of $145, then
10C+11L=145
Hence;
The system of equation are:
L+C=14
10C+11L=145
To solve 4(x-2)^2 = 16
divide each side by 4 to have (x-2)^2 = 4
take the square root of both sides
x-2 = -2 or x-2 = 2
add 2 to each side
x = 0 or x = 4
4 ( 0-2)^2 = 16
4 (-2)^2 = 16
4 (4) = 16 true
4 ( 4-2)^2 = 16
4 (2)^2 = 16
4 (4) = 16 true.
the values for x are 0 and 4.
