Answer:
x=34
y=17
Step-by-step explanation:
Let Paula's score be= x
Let Maria's score be=y
<u>Given</u><u>:</u>
x=2y
x+y=51
<u>Substitution</u><u>:</u>
2y+y=51
<u>Formula</u><u>:</u>
2y+y=51
3y=51
y=17
x=2y
x=2(17)
x=34
<u>Proof</u><u>:</u>
x+y=51
34+17=51
51=51
Hope this helps ;) ❤❤❤
The formula for momentum is:
M=Mass*Velocity
From this formula we can derive the formula for velocity:
V=Momentum/Mass
We already know momentum (10 kg m/s) and mass (2 kg). Let's plug in the numbers into the formula:
V=10/2
V=5 m/s
I read this story last year for my 7th grade year. The correct answer is A!
Answer:
x= -15/2 y=-33/2
Step-by-step explanation:
i dont know how you want to solve it but if it is "system of equations" then first solve for the first variable in on e of the equations, then substitute the result into the other equation.
