Answer:

1/7

Step-by-step explanation:

Since we do not know the number let us use the alphabet A to represent the unknown number

A × 1/3= 1/21

A/3= 1/21

Cross multiply both sides

A×21= 3×1

21A= 3

Divide both sides by the coefficient of A which is 21

21A/21=3/21

A=1/7

Hence the unknown number is 1/7

Answer:

The number to multiply with 1/3 to get 1/21 is 1/7.

Step-by-step explanation:

The question wants us to find the number you can multiply with 1/3 to get 1/21. The number is unknown but when you multiply that unknown number by 1/3 your answer should be 1/21.

Let

the number to be multiplied with = a

Therefore,

1/3 × a = 1/21

a/3 = 1/21

cross multiply

21a = 3

divide both sides by 21

a = 3/21

a = 1/7

The number to multiply with 1/3 to get 1/21 is 1/7.

Rae earns $60 for playing music on saturday nights at the local coffee house. she makes an average of $5.25 in tips per hour. wr
insens350 [35]
Okay. So for this equation, she would make $60, plus $5.25 in tips each hour. So for this, she would get $60 + 5.25h. Plug in 4 hours, and she would make $21 off of tips, plus the $60, which brings her up to $81 total. The answer is C.

What is the slope - intercept form of the equation if the line through the points (3,-1) and (-1,-5)
ikadub [295]

Answer:

Slope - intercept form:

B) y= x -4

Step-by-step explanation:

(3,-1) and (-1,-5)

Slope = (-5 + 1)/(-1 - 3)

Slope = -4 / -4

Slope = 1

Point slope form:

y + 1 = 1 (x - 3)

y +1 = x - 3

y = x - 4   <------------------slope - intercept form
