Answer:
125
Step-by-step explanation:
anything that is above .5 will round up and below .4 will round down.
Answer:
yes
Step-by-step explanation:
Direct variation is represented as
y = kx, where k is a constant.
We can rewrite y - x = 0 as
y = x (add x to both sides)
This can be looked at as
y = (1)x , so this is a direct variation relationship where k = 1
Answer:
3 1/5 ft
Step-by-step explanation:
We can set up a proportion:
, where x is how long the pants are in real life
Cross multiply:
x = (2 2/7) * (1 2/5)
It's easier if we have improper fractions, so convert the mixed numbers into improper fractions:
2 2/7 = 16/7
1 2/5 = 7/5
Now, put these back in:
x = (16/7) * (7/5) = 16/5 = 3 1/5
Thus, in real life, the pants would be 3 1/5 ft long.
Hope this helps!
Answer: 10 units
Step-by-step explanation:
If the trail starts at R(-2, 4) and goes towards S(3, 4), the distance between the two points would be the sum of the absolute value of the x values. That means it's 2 + 3, which is 5. The distance between the 2 points is five. Doing the same thing with S(3, 4), and T(3, -1) but with the y values, you get 5. adding the 2 distances up you get:
5 + 5 = 10
Answer:
x=20 and y=16
Step-by-step explanation:
4x - 6y= -16
since y=x -4, we substitute it in place of "y"
Then, 4x - 6(x-4) = -16
4x - 6x + 24 = -16
-2x+24= -16
-2x= -16-24
-2x= -40
Divide both sides by -2 then,
x=20
once we get the value of "x" we substitute in place of "y=x-4"
y=20-4
y=16
