1) x=1
2) x=2.9
3) x=-10
4) x=?
5) IDK
Answer:
I think its the third one but im not entirely sure
Step-by-step explanation:
The Answer Would Be 64 because if you divide 8/4.5 its equal to 64/36.
A and B I believe.
It would be A because jump height can be found out by the amount of force you exert to get you into the air minus the gravitational force.
It would also be B because the amount of time you run on the track can be found out by dividing the track length by your speed on the track.
Hope this helps!
Answer:
x=3. y=6
Step-by-step explanation:
So, to solve x and y, we need to take the equivelent sides of the two triangles, take their equations, and solve them.
So to find what x equals, we can take the 13, and make it equal to the 4x+1:
13=4x+1
Subtract the one from both sides:
12=4x
Divide both sides by 4:
3=x
Or
<u>x=3</u>
So we know the x value is 3.
Now lets solve for y using the bottom equations:
2x+y=8x-2y
Subtract 1y from both sides:
2x=8x-3y
Subtract 8x from both sides:
-6x=-3y
Divide both sides by -6:
x=1/2y
So we already know that x=3, lets plug that in for x, and solve for y:
3=1/2y
Or
1/2y=3
Multiply both sides by 2 to get 1y:
<u>y=6</u>
So we know that y is equal to 6.
Hope this helps!
