Answer:
It would take Samantha 6 hours to drive 105 miles.
Step-by-step explanation:
This question can be solved by proportions.
After 4 hours she had traveled 70 miles.
This means that she travels 70/4 = 17.5 miles per hour.
How many hours would it take Samantha to drive 105 miles?
17.5 miles per hour, so for 105 miles:
105/17.5 = 6
It would take Samantha 6 hours to drive 105 miles.
Answer:
y = (x +2)(x -1)(x -3)
Step-by-step explanation:
I am right
3. 5x+2y=-19
10x-7y=-16
10x+4y=-38
10x-7y=-16
11y=-22
Y=-2
10x+4c-2=-38
X=-3
4. 10x-4y=20
2x+7y=43
10x-4y=20
10x+35y=215
-39y=-195
Y=5
10x-4x5=20
X=4
Hope this helped :)
Simplifying
5m + -7 = 6m + -9
Reorder the terms:
-7 + 5m = 6m + -9
Reorder the terms:
-7 + 5m = -9 + 6m
Solving
-7 + 5m = -9 + 6m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-6m' to each side of the equation.
-7 + 5m + -6m = -9 + 6m + -6m
Combine like terms: 5m + -6m = -1m
-7 + -1m = -9 + 6m + -6m
Combine like terms: 6m + -6m = 0
-7 + -1m = -9 + 0
-7 + -1m = -9
Add '7' to each side of the equation.
-7 + 7 + -1m = -9 + 7
Combine like terms: -7 + 7 = 0
0 + -1m = -9 + 7
-1m = -9 + 7
Combine like terms: -9 + 7 = -2
-1m = -2
Divide each side by '-1'.
m = 2
Simplifying
m = 2
Step-by-step explanation:
1/10 km long, split into 4 equal parts.
so each part is 1/10 / 4 km long.
1/10 / 4 = 1/10 / 4/1 = 1×1 / (4×10) = 1/40
each athlete has to run 1/40 km.
