How do you solve 15.00 - 6.24​
sdas [7]

Answer:

8.76

Step-by-step explanation:

Simplifying

15.00 + -6.24 = b

Combine like terms: 15.00 + -6.24 = 8.76

8.76 = b

Solving

8.76 = b

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Add '-1b' to each side of the equation.

8.76 + -1b = b + -1b

Combine like terms: b + -1b = 0

8.76 + -1b = 0

Add '-8.76' to each side of the equation.

8.76 + -8.76 + -1b = 0 + -8.76

Combine like terms: 8.76 + -8.76 = 0.00

0.00 + -1b = 0 + -8.76

-1b = 0 + -8.76

Combine like terms: 0 + -8.76 = -8.76

-1b = -8.76

Divide each side by '-1'.

b = 8.76

Simplifying

b = 8.76

Becky tried to evaluate an expreisson step by step
NNADVOKAT [17]

Answer:

step 2

Step-by-step explanation:

1) so in step 2 Becky make 4/5-5/4=0

this is wrong, as we have to make common denominators first:

16/20-25/20=-9/20

so now, we got -9/20

-9/20+7=

2) make common denominators again

-9/20+140/20=131/20

this is the right answer Hope this helps!
