Answer:
Step-by-step explanation:
We need to find the LCM of 24, 72.
LCM
= Multiply all the factors
= 3 × 2 × 2 × 2 × 3
= 72.
The slope is 1, because the slope form is:
Where the m is the slope. Here, m=1.
number 3 and 4 you should answer on that axis
number 5 = 12
6.4 + 10 = 14
7.9+2 = 11
8.13 - 5 = 8
9.16 - 2 = 14
10.15 + 7 = 22
Answer:
x = 0, y = -3
Step-by-step explanation:
Multiply the first equation by 6. Now you have -30x - 18y - 54 = 0 and
4x - 18y - 54 = 0. Subtract the first equation from the second equation to get that 34x = 0, so x = 0. Plug this back in to figure out that y = -3.
which is Marcella's age
of 63 is 21 ⇔ 63÷3=21
which is Justins age
Marcella's age⇒63
Justin's age⇒23
Aimee's age⇒42
Note: I was trying to find a better way to do this but I couldn't figure it out in the top of my head so I'm sorry for the long response
