Answer:

29.5 square inches

Step-by-step explanation:

Let's divide the shape into 3 parts to make it easy for us to find the area.

- a wide triangle

- a triangle

- a shorter rectangle

For the wider rectangle, the area is;

A1 = 8 × 2 = 16 in²

For the triangle, the area is;

A2 = ½(7 - 2) × 3

A2 = 7.5 in²

For the shorter rectangle, the area is;

A3 = 3 × 2

A3 = 6 in²

Total area = A1 + A2 + A3 = 16 + 7.5 + 6 = 29.5 square inches

Which of the following is a solution to the equation x - 5/7 = -3/7
podryga [215]

Solve the equation:

          5              3
x  –  ——  =  –  ——
          7              7


           5
Add  ——  to both sides, so you get  x  isolated at the left-hand side:
           7

          5          5               3          5
x  –  ——  +  ——  =  –  ——  +  ——
          7           7              7           7

              3          5
x  =  –  ——  +  ——
              7           7


Now, add those fractions at the right-hand side of the equation:

          – 3 + 5
x  =  —————
               7

          2
x  =  ——     <———    this is the answer (first option:  2/7).
          7


I hope this helps. =)

Product of 7.69×5 be greater or less than its estimate of 8×5?
spayn [35]

The product is a bit less than the estimate. In fact, 7.69 is less than 8, and if you start with an equality, i.e.

7.69 < 8

you can multiply both sides by a positive number, and the inequality will still hold:

7.69 \cdot 5 < 8 \cdot 5

faltersainse [42]

Answer:

= 43

{7 × 2^{3} - 7} -2 ×3

Solve the brackets first

{7 × 8 - 7}  -2 ×3

{56 - 7}  -2 ×3

49  -2 ×3

49 -6

= 43
