6×4=24 right so than how many 8 can get you to 24, so you do 8,16,24 or 8×3 So it's 8×3=24 (Your welcome ^.^)
The circled ones are like terms so 6+(-8)+5 which is 3and then answer is 12x+3
hope this helps!:)
Answer:
The correct answer is yes.

Answer: She has 27 quarters.
Step-by-step explanation:
Let be "d" the number of dimes Marcy has and "q" the number of quarters Marcy has.
Based on the information provided in the exercise, we can set up the following system of equations:
<em> </em>In order to solve the system of equations, we can use the Elimination method:
- Multiply the first equation by -0.1
- Add the equations.
- Solve for "q".
Then:
Since y = x - 2, replace the y in 8x + 13y = 2 with x - 2:
8x + 13(x - 2) = 2
Simplify the equation by multiplying 13 by (x - 2):
8x + 13x - 26 = 2
Add 26 on each side:
8x + 13x = 28
Add like terms:
21x = 28
Divide by 21 on each side:
x = 28/21
Simplify the fraction:
x = 4/3
Now that we have solved for x we can now use it to plug into one of the equations to solve for y. Plug in 4/3 for x in y = x - 2:
y = (4/3) - 2
Subtract:
y = -2/3
Let's check the work to make sure it is right:
8(4/3) + 13(-2/3) = 2
32/3 + -26/3 = 2
6/3 = 2
2 = 2
As you can see the system of equations has been solved correctly.
