Question

Help solve these please 1.w + 10 = 25

2. 7.2 + b = 12 3. 5.3 + s = 15 4.p + (-25) = -10 3. m + (-1.6) = -4.8

Answer 1

1.
`w=15`

2.
`b=4.8`

3.
`s=9.7`

4.
`p=15`

5.
`m=-3.2`

Explanation:

1. For the equation
`w + 10 = 25`, subtract 10 from both sides:

`w + 10 -10= 25-10\\w=15`

2. For the equation
`7.2 + b = 12` subtract 7.2 from both sides:

`7.2 + b -7.2= 12-7.2`

`b=4.8`

3. For the equation
`5.3 + s = 15` subtract 5.3 from both sides:

`5.3 + s-5.3 = 15-5.3\\s=9.7`

4. For the equation
`p + (-25) = -10`, multiply signs and then add 25 to both sides of the equation:

`p -25= -10\\p - 25 +25= -10+25\\p=15`

5. For the equation
`m + (-1.6) = -4.8`, multiply signs and then add 1.6 to both sides of the equation:

`m -1.6+1.6 = -4.8+1.6\\m=-3.2`

Answer 2

1. w = 15

2. b = 4.8

3. s = 9.7

4. p =15

5. m = -3.2

Explanation:

1.w + 10 = 25

we have to find the value of w, so moving 10 from left side to right side

w= 25 - 10

w = 15

2. 7.2 + b = 12

we have to find the value of w, so moving 7.2 from left side to right side

b= 12 - 7.2

b= 4.8

3. 5.3 + s = 15

s= 15 - 5.3

s= 9.7

4.p + (-25) = -10

p-25 = -10

p= -10 + 25

p= 15

3. m + (-1.6) = -4.8

m - 1.6 = -4.8

m = -4.8 + 1.6

m= -3.2
