Answer:

$2.25 per pound

Step-by-step explanation:

Graph attached shows the relation between the weight of the potatoes and cost of potatoes purchased.

Cost of 1 pound of potatoes will be represented by the slope of the given line.

Since slope of a line passing through two points (x_1,y_1) and (x_2,y_2) is given by the formula,

Slope = \frac{y_2-y_1}{x_2-x_1}

Therefore, slope of the line passing through (0, 0) and (2, 4.5) will be,

Slope = \frac{4.5}{2}

          = 2.25

Therefore, cost of potatoes is $2.25 per pound.

Jennifer had a 7/8- foot board. She cut off a 1/4 foot piece that was for a project. In feet, how much of the board was left
Tems11 [23]

Answer: There was 5/8 of a foot of board left.

Step-by-step explanation:

Step 1. We need to subtract 1/4 from 7/8. To do this make it where both fractions have the same denominator.

Step 2. The easiest way to do this is to multiply 1/4 by 2.

1/4*2/2=2/8.

Step 3. Now all you got to do is subtract 2/8 from 7/8.

7/8-2/8= 5/8.

At an electronics store, the number of 37 inch HDTVs that is expected to be sold in a month is double that of 58 inch HDTVs and
ki77a [65]
Will represent as such
number of 37 inch tvs=x
number of 58 inch tvs=y
number of 50 inch tvs =z

x is double of (y+z)
x=2(y+z)
y=z
therefor
x=2(y+y)=2(z+z)=4y=4z
x=4y=4z
y=$4800
z=$2000
x=$1800


4800y+2000z+1800x=168000
undistribute the 100
100(48y+20z+18x)=100(1680)
divide the whole thing by 100
48y+20z+18x=1680
divide the whole thing by 2
24y+10z+9x=840
y=z
24y+10z=34y or 34z
34y+9x=840
convert 9x to y by multiply 4
9x times 4=36y or 36z
34y+36y=840
70y=840
divide both sides by 70
y=12
y=z
z=12
x=4z
x=4(12)
x=48






they should stock:
12      50 inch tvs
12      58 inch tvs
48      38 inch tvs

Of the 450 students in the 6th grade at Graceland middle school, 75% ride the bus to school. How many 6th grade students to not
DIA [1.3K]

Answer:

112 or 113

Step-by-step explanation:

75%=0.75

450*0.75=337.5

450-337.5=112.5

Or if 75% ride then 25% do not ride the bus.

450*0.25=112.5

Presumably you would round to 113

What are the y-intercepts to graph the equation-4x - 3y = 36
Eddi Din [679]

Answer:

Y-Int = -12

Step-by-step explanation:

First, I would change the equation to slope intercept form:

-3y = 36 + 4x

3y = -36 - 4x

y = -12-4/3x

y = -4/3x - 12
