Answer:
Mikhail is 5 years old
Step-by-step explanation:
Represent each member with a variable.
X= Gabrille
Y=Mikhail
X+Y=20 (sum of their ages is 20)
X=3y (Gabrille is 3 times Mikhails age)
Substitute 3Y into the first equation (simultaneous equation)
. 3y+y=20
. 4y=20 (divide both sides by 4)
y=5
To check your answer.
X+5=20
X=20-5
X=15
15 is 5 times 3.
Answer:
3 boxes
Step-by-step explanation:
you would divide 12 by 4 and get 3 so shade in 3 boxes
Hello,
To solve this problem, you should first put in it slope intercept form.
Here are the steps:
3y + 6 = -2x Add 6 to both sides
3y = -2x - 6 Divide both sides by 3
y = (-2/3)x - 2
The you can see that the slope is (-2/3) and the y-intercept is (0, -2).
I hope this helps,
