Julie buys 8.2 pounds of pears for $16.

About how much do they cost per pound?

Answer:

5x + 7y = -42

Step-by-step explanation:

This question will be a little easier to answer if we change the form of the original equation from slope intercept to standard form:

[tex]y=(-5/7)x-7\\(5/7)x+y=-7\\5x+7y=-49[/tex]

All parallel lines have the same slope, but what does that mean when our equation's in standard form. Well, slope only depends on the coefficients of the x and y terms, so any equation of a line in standard form with 5x + 7y on the left side will be parallel to the one in the problem. Looking through the possible choices, B. 5x + 7y = -42 is the only one that works.

Using desmos to check our work, we can see that the two lines are actually parallel!

Height of jump rope used over time.

Step-by-step explanation:The Height is stable and even so not an elevator as it goes to multiple floors not just one and is not used frequently after the same amount of time.Not the rest for the same reason.Jump rope as it can be uniform in height and time unlike the rest.

Answer:

7x+12

Step-by-step explanation:

You do 10x-3x since they both have the x variable they can be combined to make 7x and the 12 is left alone.

Answer:

7x + 12

Step-by-step explanation:

irs gonna go like

10x -3x =7x

and the answer is

7x+12

Answer:

1/2 ( 10x + 8 )

Step-by-step explanation:

first make sure everything in the parenthesis is addition. by doing this you make the 6 and 8x negatives. so it's 1/2 ( 13x + 5x + -6 + -8 + 14 ) then combine the numbers with the variable x so 13x + 5x + -8x = 10x . then the ones without variables -6 + 14 = 8. so 1/2 ( 10x + 8)

Answer:

Linear

Step-by-step explanation:

Both top and bottom are going up at a constant rate

x is going up by 9 and

y is going up by 7

Answer:

The rate's aren't equivalent.

Step-by-step explanation:

If you find a common number of hours between the two expressions such as 24 hours you will see that the pay isn't the same. $24 for 6 hours of work ($4:1hr) can be turned into $96 for 24 hours of work and $36 hours for 8 hours of work ($4.5:1) turns into $108 for 24 hours of work.

- increase

because 80 is greater than 50.

50 - 80

----------- = 30/50 = 0.6

  50

answer:

- the change is an increase by 60%

Answer:

increase of 60%

Step-by-step explanation

The change from 50 to 80 is an increase of 30

To calculate percentage increase

[tex]\frac{change}{original}[/tex] × 100%

= [tex]\frac{30}{50}[/tex] × 100%

= 60% increase

Answer: a=126, b=134, c= 110, d=146, e=46

Step-by-step explanation:

so for a you take 180-54 and that gives you A

for b you take 33,70,and A(126) and add them together then subtratct by 360 and you get b for d you take 180-33 and get 146 for c you take 180-70 and get 110 and for e you take 180 - 134(B) and you get tha answer to e

Answer:

84 points

y= 100-2x where y= total score (0 through 100) and x= # of questions wrong (0 through 50)

Step-by-step explanation:

100- 2(8) = y

100-16 = y

84=y

Since each question (x) is worth two points (2) we have to multiply each wrong question by two (2x). And then since we're deducting point from the possible points (100) we have to subtract (100-2x)

well- you cant buy any pounds-

Step-by-step explanation:

Answer:

It took 8 seconds for the leaf to reach the ground.

Step-by-step explanation:

The height of the leaf in feet can be found using the function:

y = -3.5*x + 28

where x is the time in seconds the leaf has been in the air.

You want to know how long it took for the blade to reach the ground. That is, the time it took for the blade to reach a height of 0 feet. So, replacing this value in the expression:

0= -3.5*x + 28

and solving you get:

-28= -3.5*x

(-28)÷ (-3.5)=x

8=x

It took 8 seconds for the leaf to reach the ground.

Answer:

0.6

Step-by-step explanation:

oki so to make it easier, you can convert 3/5 to 60/100

Answer:

Step-by-step explanation:

we know that 1 lb=16oz

16 oz almonds = costs 8 dollars , we divide the cost to oz

8/16=0.5 dollars / oz

4.10/0.5=8.2 oz

for 4.10 dollars you buy 8.2 oz

Step-by-step explanation:

Answer:

36pi

Step-by-step explanation:

Since the formula for the circumference is C=2*pi*r

12pi=2*pi*r we can divide and get r=6 cm

Then, we can use the formula for the area of a circle: Area=pi*r^2 and get Area=pi*6^2=36*pi.
