Answer:   5 5/16 inches

Step-by-step explanation:

3 ways to get this.

1. Estimate. You know that 8 × 5 is 40, and 40 is close to 42.  40 ÷ 8 is  5

There is only one answer close to that so choose A.

2. Calculate. Change the numbers to a decimal and divide:  42.5 ÷ 8 = 5.3125

3 . Fraction multiplication and division: Make 42 1/2 into an "improper fraction"

and multiply.   85/2 × 1/8 = 85/16   Divide  "old style" long division to get a remainder.  85 ÷ 16 = 5, remainder 5.  Put the remainder 5 over the divisor 16 to end up with 5 5/16

(6y^2-7y-3)-(2y^2-9y-7) simplify
madreJ [45]
6y^2-7y-3-2y^2+9y+7 (pretend that you're multiplying -1 to 2y^2-9y-7 which is why 9y and 7 are positive now).
Now you're able to simplify your problem, so...

6y^2-2y^2= 4y^2
-7y+9y= 2y
-3+7=4

4y^2+2y+4

Might want to check my math but that's how you do it.

Hi,

Work:

Equation;

35 - 3 \times  {10}^{2}  \div 20
1. Write division as fraction.

35 -  \frac{3 \times  {10}^{2} }{20}

2. Evaluate the power of 10².

35 -  \frac{3 \times 100}{20}

3. Reduce the fraction with 20.

35 -  \frac{3 \times   100}{20}  = 35 - 3 \times 5

4. Multiply.

35 - 15

5. Finally subtract and RESULT.

35 - 15 = 20


Hope this helps.
