1. c + 3/10 = 31/70
2. w + 6 1/2 = 10 1/6

Answers

Answer:

1. c = 1/7

2. w = 11/3

Step-by-step explanation:

1. c + 3/10 = 31/70

move 3/10 to the opposite to get c, we can do this by subtracting 3/10 from both sides

c = 31/70 - 3/10

c = 1/7

2. w + 6 1/2 = 10 1/6

same thing, move 6 1/2 by subtracting it from both sides

w = 10 1/6 - 6 1/2

w = 11/3

1. C=1/7
Work:
You have to subtract 3/10 on both sides.
2. -4/3
You have to subtract 6 1/2 on both sides.

BRAINLIEST IF CORRECT PLEASE USE WORK!What is the x-intercept of the line with this equation 1/3x+y=−15 ?

Enter your answer in the box.

Answers

y-ordinate of x-intercept is 0 .Putting y = 0 in the equation we get 1 3 x + 0 = − 15 or 1 3 x = − 15 or x = − ( 3 ⋅ 15 ) = − 45 ∴ x=intercept is ( − 45 , 0 ) graph{-1/3x-15 [-80, 80, -40, 40]}[Ans]


Hope this helped.

Your answer:

x-intercept is ( -45 , 0 )

Answer:


To find the x-intercept, substitute in  0  for  y  and solve for  x. To find the y-intercept, substitute in  0  for  x  and solve for  y.

x-intercept: (−45,0)

y-intercept:  (0,−15)

The graph shows the miles per gallon of gasoline a car uses on a trip.What does the rate of change represent in this situation?



Select from the drop-down menu to correctly complete the sentence.


The rate of change represents ​

Answers

Answer: The rate of change represents  number of miles traveled for every 1 gallon of gas used.


Step-by-step explanation:

A rate of change is a rate that illustrates how dependent variable changes in relation to independent variable.

Here the independent variable is "gas used in gallons".

and the dependent variable is "distance traveled in miles"

Thus the rate of change =\frac{\text{change in distance}}{\text{change in amount of gas}}

Thus, It illustrates number of miles traveled for every 1 gallon of gas used.

Hence, The rate of change represents number of miles traveled for every 1 gallon of gas used.


Answer:

1.) The number of miles traveled for every 1 gallon of gas used.

Step-by-step explanation:

The rate of change represents number of miles traveled for every 1 gallon of gas used.

the area of a rectangular patio is 5 5/8 square yards, and its length is 1 1/2 yards. what is the patio's width, in yards

Answers

area = length x width
if the area is 5 5/8, and the length is 1 1/2, all you have to do to find the width is divide the area by the length.
5 5/8 / 1 1/2 = 3 3/4 yards

hope this helped!!
well the area of a rectangle is width times length, so you can flip the equation to say that width = area divided by length, or length = area divided by width :)
