Answer:
0.27
Step-by-step explanation:
You take 1.75, and subtract 1.48 from it. 1.75
<u>- 1.48</u>
0.27
A = 5 + B
A + 5 = 2B
Let's get one of the variables on one side.
A = 5 + B
A = 2B - 5
By the transitive property
5 + B = 2B - 5
Solve for B.
5 = B - 5
10 = B
Use 10 = B in an earlier equation to find A.
A = 5 + B
A = 5 + 10
A = 15
Abe has 15$ and Ben has 10$.

Answer:
x=8.5
Step-by-step explanation:
To solve this equation, we want to find out what x is. To do this, we need to get x by itself.
Perform the opposite of what is being done to the equation. Remember to perform everything to both sides.
4(x-5)=14
4 is being multiplied by x-5. The opposite of multiplication is division. Divide both sides by 4.
4(x-5)/4=14/4
x-5=14/4
x-5=3.5
5 is being subtracted from x. The opposite of subtraction is addition. Add 5 to both sides.
x-5+5=3.5+5
x=3.5+5
x=8.5
Let's check our solution. Plug 8.5 in for x in the original equation.
4(x-5)=14
4(8.5-5)=14
4(3.5)=14
14=14
Both sides of the equation are the same, so we know our solution, <u>x=8.5 </u>is correct.
