Answer:
40 units
Step-by-step explanation:
-7 to 6 is 13 units and -3 to 4 is 7 units, it asks for perimeter so 13 x 2 + 7 × 2
Answer:
348 out of 725
Step-by-step explanation:
This is a ratio question, giving us a sample that we can use to extend the number to all students.
12/25 students play a sport so we want the value of x in x/725
So:
12/25 = x/725
Cross-Multiply:
25x = 8700
Divide by 25 to get x:
348
You can also check by dividing these ratios to see if you get the same number. In this case, you do (.48).
Solution to the system of equation (-2,5)
Answer:
- B) y = negative 4 x + three
Step-by-step explanation:
<u>Find the slope of the line that goes through (0, 8) and (2, 0):</u>
- m = (y₂ - y₁)/(x₂ - x₁)
- m = (0 - 8) / (2 - 0) = -8/2 = -4
Parallel lines have equal slopes.
<u>Looking at the choices we see only one of them has the slope of -4:</u>
Answer:
6 hours
Step-by-step explanation:
Let the total work be X
Combined speed: X/2
Ron's speed: X/3
Harry's speed: S
X/2 = X/3 + S
S = X/2 - X/3 = (3X - 2X)/6 = X/6
Harry's speed is X/6, so he'll take 6 hours
