Answer:
A.
Step-by-step explanation:
4y = 12x + 16
3x = y - 4
=>
y = 3x + 4
using that in the first equation
4(3x+4) = 12x + 16
12x + 16 = 12x + 16
=> both lines/equations are identical, so they have infinitely many solutions.
If h=4, then 5(4)+7= 27. Using PEMDAS, do multiplication first, so 20, then add the 7.
Answer:
multiply 1 1/3 by 8x6 and see how many packages
Answer:
Step-by-step explanation: 20x+15(160-x)=2625
20x+2400-15x=2625
5x=225
x=45
160-x=115
rate of first mechanic= $45/hr
rate of second mechanic=$115/hr
