Answer:
-32/9
Step-by-step explanation:
4/9=w+4
4/9-4/1=w
4-36/9=w
w=-32/9 or w=-3.56
Answer:
45 miles
Step-by-step explanation:
Marco's average speed is ...
(75 mi)/(5/3 h) = 75·3/5 mi/h = 45 mi/h
Marco's rate of travel is 45 miles in one hour.
Answer:
x = 1/3
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other:
21x = 7
Divide 21 from both sides:
(21x)/21 = (7)/21
x = 7/21
x = 1/3
x = 1/3 is your answer.

Answer:
y = 1x - 5
Step-by-step explanation:
We will use the slope equation for this: y = mx + b
y is our output/answer
m is our slope, or the rate of change
x is our x coordinate. For example, in (3,2) x would be 3.
b is our y intercept, or where the line passes through the y axis.
Knowing this, we can fill out the blanks.
when we look at one point on the grid, and then find the next closest number from the point we chose, we can see that the slope is 1 so we now have: y = 1x + b
to find b, we find where the line passes over the y axis which on our grid is -5. Normally we would write: y = 1x + 5 Since we have a negative 5 or -5, we will change the + to a -
This means we write y = 1x -5.
I hope this helps you and have a great day :D
Answer:
c = 4
See explanation
Step-by-step explanation:
Given:
4c = 3c - 4
Your calculation:
4c = 3c + 4
4c = 4 - 3c
4c = 1c
c = 4/1
c= 4
Correct calculation:
4c = 3c + 4
Collect like terms by subtracting 3c from both sides
4c - 3c = 3c + 4 - 3c
c = 4
Check:
4c = 3c + 4
4(4) = 3(4) + 4
16 = 12 + 4
16 = 16
Therefore,
Your final answer is correct but your method of calculation is not correct
