Answer:

B. 713

Step-by-step explanation:

159 ÷ 1450 = 0.10965517241

0.10965517241 * 6500 = 712.75862069

712.75862069 ≈ 713

Answer: p = 75 + 250

Equation of the situation, in slope-intercept form is given as .

Where,

b = y-intercept

m = slope

n = number of computers sold

p = total cost

All we need to find is the value of m and b.

Using two pairs from the table of values, (4, 550) and (6, 700):

Substitute n = 4, p = 550, and m = 75 in , and find the value of b.

Subtract 300 from each side

b = 250

Substitute m = 75, and b = 250 in

✅Equation that represents the situation would be:

Answer:

9. B 10. C 11. A 12. C

Step-by-step explanation:

Greater rate of change simply means slope! Which ever of the functions has the greatest slope (positive or negative)

9.

a. The graph shows the line going up by 4, and across by 3, or, a slope of 4/3

b. the table is increasing by 10, so, 10/1

c. -6 = -6/1, out of all of these, we divide by the denominators and determine which number is the greatest, ignoring whether or not the value is positive or negative

a. 4/3 = 1.333333

b. 10/1 = 10

c. -6/1 = -6 (remember, ignore the sign)

In this case, B is the greatest number, therefore, it has the greatest rate of change

10.

a. -3 / 3 = -1 (ignore the negative!)

b. 2/1 = 2

c. 4/1 = 4

In this case, C, is the greatest number, meaning its rate of change is highest

11.

a. -1/3 = -0.333333 (ignore the yk what!)

b. 0.25/1 = 0.25

c. -1/5 = -0.20 (you already know)

In this case, a, is the greatest number, meaning, its rate of change is the highest

12.

a. 0/1 = 0

b. 0.5/1 = 0.5

c. 2/1 = 2

In this case, c, is the greatest number, meaning, its rate of change is the highest.

Answer:

81 cubic feet of wood

Step-by-step explanation:

Divide it into 5 sections, each 3 feet long because it is 15 feet long.

(1*3*3) + (2*3*3) + (3*3*3) + (2*3*3) + (1*3*3) =

9 + 18 + 27 + 18 + 9 = 81

Pretty sure it’s A, 68.

Step-by-step explanation:

Compound shapes, so 8 x 5 (5 from the 12-7)= 40. Then, 4 x 7 = 28. add them together, 68.

Answer:

Step-by-step explanation:

Answer: Jeremiah was a great storyteller, but as soon as Ellie went to college, she changed. One of them is not wanting to hear all the stories he used to tell her. It was right after Ellie went back to school that Grandpa Jeremiah had a stroke, and Macon started coming around. And just about the time, Ellie came from school the, next summer his health started to deteriorate. Dr. Crawford said he had maybe a week or two at best, and from this news, everyone was devastated. And the whole family would start helping poor grandpa Jeremiah. While Macon would hang around more due to Jeremiah and his stories. But the family was concerned about him doing this rather than him resting, and that this would affect his health. But the doctor told them to allow grandpa because if it makes him feel better, it would be the greatest medicine for him. And soon, everyone started getting closer as a family as the end was coming near for grandpa Jeremiah. And soon ended up grieving together after his passing.

Answer:

221.25

Step-by-step explanation:

302.16 - 77.56 = 224.6

224.6 - 3.35 = 221.25

Answer:

221.25

Step-by-step explanation:

302.16 - 77.56= 224.6 - 3.35=221.25  she took away money from the bank  (302.16 - 77.56) then after that she gives (subtraction because she is taking away or giving something that is hers and making her have less.) minus 3.35 which will give you the answer.

Answer:

10.8

Step-by-step explanation:

If you do 33.90 - 1.50 it gets you 32.4 which from there you should just have to divide it by 3 and get 10.8.

Answer:

13.4666666667 !

Step-by-step explanation: First you have to multiply the tax by 3 because you got 3 cds which means 3x more tax! Then subtract that to get how much those 3 cds are without tax (40.4), after that divide it by 3 to find how much it was for each cd!

Answer:

5/7 =55

5x/7 =55

7 ⋅ 5x/7 = 7 ⋅ 55

5x =  7⋅ 55

x= 77

1/5/6 = 6x/6

x= 1/30

x+ 2.17 = 5

x+ 2.17 = 5 - 2.17 = 5 - 2.17

x=2.83

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) [tex]\frac{5}{7}x = 55\\[/tex]

Multiply both sides by 7,

[tex]7*\frac{5}{7}x=55*7\\[/tex]

[tex]5x = 55 * 7[/tex]

Now divide both sides by 5

[tex]\frac{5}{5}x=\frac{55*7}{5}\\\\x = 11*7\\\\x = 77[/tex]

ANS: x = 77

2) 6x = 1/5

Divide both sides by 6

[tex]\frac{6}{6}x=\frac{1}{5*6}\\\\x = \frac{1}{30}[/tex]

3) 2.17 + x = 5

Subtract 2.17 from both sides

2.17 - 2.17 +x = 5 - 2.17

x = 2.83

[tex]4) \frac{20}{3}=\frac{10}{9}x[/tex]

Multiply both sides by 9

[tex]\frac{20}{3}*9=\frac{10}{9}x*9\\\\20*3=10x\\[/tex]

Divide both sides by 10

[tex]\frac{20*3}{10}= \frac{10}{10}x\\\\2*3 = x\\\\x = 6[/tex]

Step-by-step explanation:

Answer:

350 adult tickets were sold

Step-by-step explanation:

Let x represent the number of adult tickets sold.

Since there were 60 fewer student tickets sold than adult tickets, the number of student tickets sold can be represented by x - 60

Create an equation that sets up these terms equal to 640, then solve for x:

(x) + (x - 60) = 640

2x - 60 = 640

2x = 700

x = 350

So, 350 adult tickets were sold

Answer:

8^2 + b^2 = 10^2, and b = 6

Step-by-step explanation:

This is a right triangle, so use the Pythagorean theorem

a^2 + b^2 = c^2, where 8 is a, b is b, and 10 is c

8^2 + b^2 = 10^2

64 + b^2 = 100

100 - 64 = 36

b^2 = 36

b = 6
