1 answer:

Answer:

141 1/4

Step-by-step explanation:

You are looking for TOTAL change, thus, both values will be positive. In order to add both fractions, you need to convert the denominator for 90 1/2 into a 4. This becomes 90 2/4.

Now add both mixed fractions.

3/4 + 2/4 = 1 1/4

90 + 50 = 140

140 + 1 1/4 = 141 1/4

2+d=2-3(d-5)-2 Pls show work
defon
2 + d = 2 - 3(d- 5) - 2

First, cancel 2 on both sides. / Your problem should look like: d = -3(d - 5) - 2
Second, expand. / Your problem should look like: d = -3d + 15 - 2
Third, simplify -3d + 15 - 2 to get -3d + 13. / Your problem should look like: d = -3d + 13
Fourth, add 3d to both sides. / Your problem should look like: d + 3d = 13
Fifth, add d + 3d to get 4d. / Your problem should look like: 4d = 13
Sixth, divide both sides by 4. / Your problem should look like: d =  \frac{13}{4}

Answer as fraction: d =  \frac{13}{4}
Answer as decimal: d = 3.25
