Answer:
14 7/12
Step-by-step explanation:
You take 6 3/4 and subtract 1/2 cup, which equals 6 1/4. Then you take 6 1/4 and divide that by 3. Then you multiply that answer (2 1/12) by seven.
3(x+5)=8x~~~First we distribute (we multiply 3 by x and 3 by 5)
3x+15=8x~~~Remove 3x from both sides
-3x -3x
15=5x~~~~Turn this equation around so x is on the other side
5x=15~~~Divide by 5x
÷5x ÷5x
x=3
3/4 equals 15/20, so b+3=15. B=12
Answer:
Goal = x
45000 = 9/10 * x
x = 45000 * 10/9 = 50000

An equation has an infinite number of solutions if the left and right sides are identical. Let's simplify them both and then decide the value of ?.
Left hand side:

Right hand side:

So, both sides have a numeric part of -20. We can use the "?" value to make sure that the literal part is the same as well. So, we want
