If we want to calculate the percentage of the correct answer, we can use this formula.

(17/20) * 100
85 percentage

5 0

100 divided by 20 is 5. So 17 times 5 is 85%

One of the giraffes, Bernard, is sick. Last week he weighed 2,490 pounds. This week he weighs 2,312 pounds. If w represents the

victus00 [196]

Answer:

$w+2,312=2,490$

$w=178\ pounds$

Step-by-step explanation:

Let

w ----> the amount of weight lost in pounds

we know that

The amount of weight Bernard lost plus the weight of this week must be equal to the weight of the last week

The linear equation that represent this situation is

$w+2,312=2,490$

solve for w

subtract 2,312 both sides

$w=2,490- 2,312=178\ pounds$

A worker carries jugs of liquid soap from a production line to a packing area, carrying 4 jugs per trip. If the jugs are packed

Allisa [31]

Answer:

B. 2

Step-by-step explanation:

We have been given that a worker carries jugs of liquid soap from a production line to a packing area, carrying 4 jugs per trip.

Since worker has made 17 trips, so total number of hugs of liquid soap would be 17 times number of jugs carried per trip.

$17\times 4=68$ .

Since each carton holds 7 jugs, so number of cartoons would be $\frac{68}{7}$ .

$\frac{68}{7}\Rightarrow \frac{63+5}{7}=9\frac{5}{7}$

We can see that there are 9 completely filled cartoons and there are 5 jugs remaining, so we need $7-5=2$ jugs.

Therefore, we need 2 jugs to fill the 10th cartoon and option B is the correct choice.

write an equation in standard form of the line that passes through the point (-2,7) and has a slope of -1

gavmur [86]

Step-by-step explanation:

First, sub in the ordered pair to find y int

(7) = -1(-2) + b

7 = 2 + b

b = 5

So the equation in y int form is

y = -1x + 5

This when convert to stardard form is

x + y = 5
