270 because 120/24 = 5 5x54 = 270
Answer:
4 years
Step-by-step explanation:
Note that:
1 foot = 12 inches
1 2/3 feet = x inches
We cross multiply
1 foot × x inches = 1 2/3 feet × 12 inches
x inches = 1 2/3 feet × 12 inches/1 foot
x inches = 5/3 × 12 inches
x inches = 20 inches
A tree grows 5 inches each year. How many years will it take for the tree to be 1 2/3 feet tall = 20 inches
This is calculated as
5 inches = 1 year
20 inches = x year
Cross Multiply
5x = 20 inches × 1 year
x = 20/5
x = 4 years
It would take the tree 4 years to be 1 2/3 feet tall
Answer:

Step-by-step explanation:
we know that
The y-intercept is the value of the function when the value of x is equal to zero. Also is called the initial value of the function
I will analyze two cases
Part 1) we have

so
For x=0
substitute

therefore
The y-intercept is the point (0,0)
Part 2) we have

so
For x=0
substitute

therefore
The y-intercept is the point (0,-1)
Answer:
5x - 2y = 20
Step-by-step explanation:
Find x-intercept by substituting y for 0
5x - 2y = 10
5x - 2(0) = 10
Isolate x to get x-intercept.
5x = 10
x = 2
(2, 0)
Twice of this intercept is (4,0).
Find y-intercept by substituting x for 0
5x - 2y = 10
5(0) - 2y = 10
Isolate y to get y-intercept.
-2y = 10
y = -5
(0, -5)
Twice of this intercept is (0, -10).
A line should have the y-intercept -10 and x-intercept 4.
In original equation, double the 10.
Test for x and y intercepts.
5x - 2y = 20
-2y = 20
y = -10
5x - 2y = 20
5x = 20
x = 4
An equation is 5x - 2y = 20.
100% of the people present would be 60.
