Multiple 7/9 to the sum of 8 3/7 and 5 11/14

Brums [2.3K]

$\frac{7}{9} \times (8 \frac{3}{7} + 5 \frac{11}{14}) = \\$

$\frac{7}{9} \times (8 \frac{6}{14} + 5 \frac{11}{14} ) = \\$

$\frac{7}{9} \times (13 \frac{6 + 11}{14}) = \\$

$\frac{7}{9} \times (13 \frac{17}{14}) = \\$

$\frac{7}{9} \times (14 \frac{3}{14}) = \\$

$\frac{7}{9} \times ( \frac{14 \times 3 + 3}{14}) = \\$

$\frac{7}{9} \times ( \frac{42 + 3}{14}) = \\$

$\frac{7}{9} \times ( \frac{45}{14}) = \frac{7 \times 45}{9 \times 14} = \frac{5}{2} \\$

BlackZzzverrR [31]

Answer:

$20d = c

Step-by-step explanation:

Since the cost is $20 per day, $20d ($20 for how many days) would be the start of the equation.

C = cost, and $20d will determine the cost, so $20d = c

is your final answer/equation.

How many pounds of a 4% solution of borax must be added to 24 pounds of a

Marrrta [24]

Answer:

8 pounds of 4% solution of borax

Step-by-step explanation:

Let x be the 4% solution

24 pounds of 12% solution

obtain a 10% solution of borax that is (x+24) pounds

4% is 0.04 and 12% is 0.12 , 10% is 0.1

$0.04x+24(.12)=0.1(x+24)$

solve the equation for x

$0.04x+24(.12)=0.1(x+24)\\0.04x+2.88= 0.1x+2.4\\2.88= 0.06x+2.4\\0.48=0.06x\\x=8$

so 8 pounds of 4% solution of borax
