How many solutions exist for the given equation? <br><br> 3(x-2) =22 -x

kenny6666 [7]

Answer:

one solution

Step-by-step explanation:

3(x-2) =22 -x

Distribute

3x - 6 = 22-x

Add x to each side

3x+x-6 = 22-x+x

4x+6 = 22

Subtract 6 from each side

4x+6-6 = 22-6

4x= 16

Divide by 4

4x/4 = 16/4

x=4

There is one solution

The owner of a retail store is tracking his inventory for an annual report. The graph shows the remaining Inventory for a partic

padilas [110]

Answer:

y = -2.8x +69.4

Step-by-step explanation:

Let y represent units of inventory, and x represent days since the last replenishment. We are given points (x, y) = (3, 61) and (13, 33). The line through these points can be described using the 2-point form of the equation of a line:

... y -y1 = (y2-y1)/(x2 -x1)(x -x1)

Filling in the given point values, we have ...

... y -61 = (33 -61)/(13 -3)(x -3)

Simplifying and adding 61, we get ...

... y = -2.8x +69.4

Cody has 7/8 pound of cheese. he uses 1/7 since there are 16 ounces in a pound how much is left

bagirrra123 [75]

Step One
Find the fraction left.
Starting amount = 7/8 pound
Used amount = 1/7 of a pound.

The common denominator of these two fractions is 8 * 7 = 56

Amount left = amount started with - amount used
Amount left = 7/8 - 1/7
Amount left = $\frac{7 *7 }{8 * 7} - \frac{1 * 8}{7 * 8}$
Amount left = $\frac{49 }{56} - \frac{ 8}{56}$
Amount left = 41 / 56 pounds

Step Two
Convert the Answer to ounces.

Ounces = (41/56) * 16
Ounces = 11.71 ounces almost 11 3/4

a student must have an average on five test that is greater than it equal to 80% but less than 90% to receive a final grade of B

Bad White [126]

Answer:

89–100

Step-by-step explanation:

Let x represent the grade on the fifth test. The average for 5 tests wants to be between 80 and 90, so we have ...

80 ≤ (78 +62 +91 +80 +x)/5 ≤ 90

Multiplying by 5 gives

400 ≤ 311 +x ≤ 450

Subtracting 311 gives the range for the fifth test grade.

89 ≤ x ≤ 139

Since the maximum available score is 100, the range on the 5th test for an overall B grade is ...

89 ≤ x ≤ 100 . . . . where x is the grade on the 5th test
