Find value of 'k' and solve for unknown variable

Mathematics
1 answer:
Veseljchak [2.6K]3 years ago
7 0

Answer:

k = 27/4

y = 283.5

Step-by-step explanation:

Let

y = amount of water used

x = number of dogs washed

y = kx

y = 81 gallons

x = 12 dogs

y = kx

81 = k * 12

81 = 12k

Divide both sides by 12

81/12 = 12k/12

k = 81/12

k = 27/4

k = 6.75

Find x when y = 42 dogs

y = kx

y = 27/4 * 42

y = (27*42) / 4

y = 1,134 / 4

y = 283.5

y = amount of water used = 283.5 gallons

In her poems, Alice Walker retrieves and ------- parts
GalinKa [24]

The correct answer is option a) revitalizes . . consign to.

In her poems, Alice Walker retrieves and revitalizes parts of Black culture that some have been all too quick to consign to the past as fossilized artifacts.

The meaning of "revive" is "to strengthen," whereas "retrieve" is "to recuperate or regain."

Furthermore, the phrase "consign to the past" refers to sending something into the past in order to get rid of or get away from it, therefore Option A is the best fit for the statement.

As a result, by removing its ancient, fossilized objects, the poet is attempting to reclaim or reinforce some aspects of black culture.

A store is having a sale on chocolate chips and walnuts. For 8 pounds of chocolate chips and 3 pounds of walnuts, the total cost
Bad White [126]

Answer:

chocolate chips are $2.00 per pound.

nd walnuts must be $3.50 per pound.

Step-by-step explanation:

Let x be the price of walnuts and y the price of chocolate chips.

2x + 5y = 17 (i)

8x + 3y = 34 (ii)

Multiply (i) by 4 to get

8x + 20y = 68

Subtract (ii) to get

 17y = 34

Dividing by 17, we see that chocolate chips are $2.00 per pound.

Substituting y=2 in (i) or (ii), walnuts must be $3.50 per pound.

Any help would be appreciated(brainly for best answer)
Simora [160]

Answer:

b.

m<1 = 80 degrees because of the alternate angles rule.

m<2 = 100 degrees because angles on a straight line equals 180 degrees.

c.

m<1=75 degrees because again of the alternate angle rule.

m<2= 60 because that angle is equal to diagonally upper angle (I'll call it Z) and that angle would equal 60 because 180-120=60

Step-by-step explanation:

You really didn't need to do such complex math. If you want me to explain it more in detail, please let me know.
