Step-by-step explanation:
0+1 = 1
1/2+1/2= 1
-50 + 51= 1
Each part of the race is 1/10 of a mile. And Marsha finishes 5 parts. Every time you complete a checkpoint, you finish that part of the race. If you only finish one part, then you only completed 1/10 of the race. If two, then 2/10. And so one.
Or we can multiply 1/10 by 5.
1/10 * 5 = 5/10
Now simplify it.
5/10 = 1/2
So, the answer to this question would be C 1/2 mile.
The car can travel 1120 miles because 20 times 56 equals 1120
Answer:
32 inches
Step-by-step explanation:
Assuming 76 inches is perimeter, we'll say that w is width
Length = 5w + 2
Perimeter = w + w + (5w+2) + (5w+2) = 76 inches
12w + 4 = 76
Subtract 4 on both sides
12w = 72
Divide 12 on both sides
w = 6
---
If the width is 6, then 5w + 2 = 5(6) + 2 = 30 + 2 = 32
---
Width - 6 inches
Length - 32 inches
Perimeter - 76 inches
Since it was stated that the equation is linear, therefore
we can use the slope point formula to find for the slope and intercepts. The
linear equation has a form of:
y = mx + b
where y is the retail price, x the wholesale price, m the
slope and b the y-intercept
m = (y2 – y1) / (x2 – x1)
m = (238 – 112) / (175 – 85)
m = 1.4
So the equation now becomes:
y = 1.4x + b
Plugging in any pair to find for b:
112 = 1.4(85) + b
b = -7
So the full equation is:
<span>y = 1.4x - 7</span>
<span>or</span>
<span>R = 1.4C - 7</span>
