Answer:
3, 12
Step-by-step explanation:
"x" is the larger number,
"y" is the smaller number.
Given
x + y = 15
x / y = 4
manipulate the equations for the problem
x / y = 4
*y *y
x = 4y
solve the system of equations by the methord of substitution:
x + y =15
4y + y = 15
5y = 15
y = 3
Subsitute back into the equations given.
x = 4y
x = 12
Answer:
5x = 14
Step-by-step explanation:
If 5 yards of fabric is $14 you need an equation that would solve how much 1 yard of fabric costs. You can say 5x = 14 or x = 2.8 which means that one yard of fabric (1x or just x) is $2.80.
Answer:
Step-by-step explanation:
We would apply the formula for exponential growth which is expressed as
A = P(1 + r)^t
Where
A represents the population after t years.
t represents the number of years.
P represents the initial population.
r represents rate of growth.
From the information given,
P = 5655
r = 1.4% = 1.4/100 = 0.14,
a) Therefore, the equation that estimates the population t years after 2010 is
A = 5655(1 + 0.14)^t
A = 5655(1.14)^t
b) in 2022, the number of years t = 2022 - 2010 = 12
Therefore,
A = 5655(1.14)^12
A = 27245
To solve this, take the total distance (5,280) divide by the average step (42).
5,280/42 = 125.714
