Mathematics

The GCF of 63 and 81 is 9, so you can use that as the factor outside of the parentheses. Divide both numbers by 9 and write the sum as 9(7 + 9). You can check that the sum 63 + 81 is the same as the product 9(7 +9).

63+81=9(7+9)
You can check your answer by:
9(7+9)
9(7+ )=63
9( +9)=81
Multiplying the GCF by every term in the parenthesis.

Ksivusya [100]

Answer:

The 400 coupon is  80 cents better

Step-by-step explanation:

First find the sale price with the coupon

744 - 400 = 344

Now find the sale price with the discount

100-55 = 45

We will pay 45% of the original price

744*45%

744*.45

CAN SOMEONE PLEASE HELP ME ASAP PLEASEE ANYBODY LITERALLY ANYONE OUT THERE PLEASE. Determine m∠ABQ and determine m∠BCR.
s2008m [1.1K]

Answer:

ABQ  = 139

BCR is the same as QBC since they are alternate interior angles

BCR = 41

Step-by-step explanation:

CBQ and SCB are same side interior angles so they add to 180

2a-9  + 5a +14 = 180

Combine like terms

7a +5 = 180

Subtract 5 from each side

7a = 175

Divide by 7

7a/7 = 175/7

a = 25

ABQ  is the same as SCB  since they are corresponding angles so

ABQ = SCB = 5a+14 = 5*25+14 = 125+14 = 139

BCR is the same as QBC since they are alternate interior angles

BCR = QBC = 2a-9 = 2*25 -9 = 50-9 = 41

Simple the expression <br> ( 3k + 4 1/5) + 8 3/5
lesantik [10]

Answer:

3k+12\frac{4}{5}

Step-by-step explanation:

(3k+12\frac{4}{5})

Convert mixed numbers to improper fractions:

a\frac{b}{c}=\frac{a*c+b}{c}

4\frac{1}{5}=\frac{4*5+1}{5}

=\frac{21}{5}

=(3k+\frac{21}{5} )+\frac{43}{5}

Add the fractions

\frac{21}{5}+\frac{43}{5}

\frac{21}{5} \frac{43}{5} =\frac{64}{5}

=3k+\frac{64}{5}

Divide 64 by 5

\frac{64}{5}12.8 or 12\frac{4}{5}

=3k+12\frac{4}{5}
