Manuel buys 7.9 pounds of strawberries. Each pound costs $3.89. Which expression gives the best estimate of the cost of the strawberries? (8)($4)(7)($4)(8)($3)(7)($3)

The options you gave are extremely confusing, but if you round 7.9 it is 8, and if you round $3.89 it is $4. Therefore, the best estimate would be 8•$4, or $32

Answer: Its {8}{4$}

Step-by-step explanation:

because 7.9 rounds up to 8 and 3.89 rounds up to four.

What is the perimeter and area of. 4 in by 5 in

To find the perimeter use the formula s+s+s+s

(One s for each side)

Assuming the shape is a quadrilateral, each side should be added

So 4+4+5+5=18

The perimeter is 18in

To find the area do l×w

Once again, assuming the shape is a parallel (the formula changes depending on the shape)

4×5=20

The area of the shape is 20in^2

(One s for each side)

Assuming the shape is a quadrilateral, each side should be added

So 4+4+5+5=18

The perimeter is 18in

To find the area do l×w

Once again, assuming the shape is a parallel (the formula changes depending on the shape)

4×5=20

The area of the shape is 20in^2

What does 1-5+1x(4x4-31)x8 equal

Assuming that 1x(4x4-31) means 1 times (4 times 4-31)

aka that the x's mean multiplcation

PEMDAS

parenthasees first

exponents

multiply or divide

add or subtract

simplif inner parenthasees

4 times 4-31

multpily

4*4=16

16-31=-15

now we have

1-5+1 times (-15) times 8

multiply

1 times -15=-15

-15 times 8=-120

now we have

1-5-120

add/subtract

1-5=-4
