Answer: In 4 minutes he will make 5 portraits
Step-by-step explanation:
1) Graphing- If you graph the numbers you will easily be able to identify the answer.
2) Substitute- Substitute numbers in for x or y until they're equal on both sides.
EX: 2x+2=10
Substitute numbers in until you get a number that makes it equal on both sides
x= 4
3) Elimination- Eliminate numbers from both sides until they're equal.
Hope this helped! :)
Answer:
X>4
Step-by-step explanation:
Answer:
990
Step-by-step explanation:
M/J = 2/7
J = 3/4 L
L = M + 396
7M = 2J
J = 3.5M
3.5M = 3/4 L
L = 4/3(3.5M)
L = 14/3 M
14/3 M = M + 396
11/3 M = 396
M = 3/11 × 396
M = 108
L = M + 396
L = 108 + 396
L = 504
J = 3/4 L
J = 3/4 × 504
J = 378
M + L + J = 108 + 504 + 378 = 990
