Answer:
Blue marbles: 18
Green marbles: 25
Step-by-step explanation:
First off, we have to define our variables.
g = # of green marbles
b = # of blue marbles
We know two equations:
g + b = 43 and g = b + 7
If you're wondering how I got the first equation, it was because the number of green and blue marbles is 43. For the second equation, we know that there are 7 more green marbles than blue marbles.
Now, we have an equation for the number of green marbles. We can plug that equation into the equation g + b = 43.
So, (b + 7) + b = 43.
When we simplify it, we get 2b + 7 = 43.
We subtract 7 from both sides, which gets us 2b = 36.
Now, b = 36/2.
b = 18.
So, we found out the number of blue marbles that we have. We know that g + b = 43. Now, all we have to do is plug in the number of blue marbles into that equation to find out the number of green marbles.
g + 18 = 43.
g = 43 - 18.
g = 25.
Thus, the number of green marbles we have is 25 and the number of blue marbles is 18.
Luis and Arnold did their own car wash during the weekends this past Summer. They made a total of $1,200 together. They decided they were going to invest their money. So they invested in stocks for Tesla. The interest they are making is at 12%. How much money would they earn after 7 years?

3(5+4y)+8-2y how to do this plz
Answer:
[tex]3\left(5+4y\right)+8-2y=10y+23[/tex]
Step-by-step explanation:
Given
As the expression is given by
[tex]3(5+4y)+8-2y[/tex]
To determine
Simplify the expression
Let us simplify the expression
[tex]3(5+4y)+8-2y[/tex]
Expand 3(5 + 4y) = 15 + 12y
[tex]3\left(5+4y\right)+8-2y=15+12y+8-2y[/tex]
grouping like terms
[tex]=12y-2y+15+8[/tex]
[tex]=10y+23[/tex]
Therefore,
[tex]3\left(5+4y\right)+8-2y=10y+23[/tex]
Evaluate the following expression: 8x - 6 - 7y + 3 use x=3 and y=6
Answer:
-27
Step-by-step explanation:
8x - 6 - 7y + 3
X = 3 Y = 6
8(3) - 6 - 7(6) + 3
8 x 3 = 24
7 x 6 = 42
24 - 6 - (42 + 3)
(24 - 6) - 45
18 - 45 = -27

A roller coaster accelerated from rest to 55 m/s by the time it reached the first hill. The roller coaster took 15 seconds to climb to the top of the hill. What was the acceleration of the coaster?
Answer:
I believe the acceleration is 3.66666666667 m/s
Step-by-step explanation:
Acceleration formula: a = vf - vi / t
Initial velocity: 0 (I believe it was 0, as it wasn't moving in the beginning)
Final velocity: 55 m/s
Time: 15 s
Substituting values: 3.66666666667 = 55 - 0 / 15
