Answer: 43
Step-by-step explanation:
For (-0.75+6)-(2.5x-9) all you have to do is multiply the negative into the 2nd brackets and collect like terms. Same with 8(5x-3y) all u have to do is multiply in the 8.
for the 4x+20 and 6x+54 all u do is factor out a common number(LCD- lowest common denominator)

Answer:
1 1/4
Step-by-step explanation:
34÷710=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
34×107=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
3×104×7=3028
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 30 and 28 using
GCF(30,28) = 2
30÷228÷2=1514
The fraction
1514
is the same as
15÷14
Convert to a mixed number using
long division for 15 ÷ 14 = 1R1, so
1514=1114
Therefore:
34÷710=1 1/4
