Answer: x=15, y= 10
Step-by-step explanation:
Answer: x=15, y=10
*Note: x and y are only variables used to solve this problem, but know that the two numbers are 15 and 10.
Step-by-step explanation:
For this problem, we can use system of equations. Let's use x for one number and y for the other.
First Equation:
x+y=25
We get this equation because it states that the sum of the two numbers is 25.
Second Equation:
y=x-5
We get this equation because it says one number (y) is 5 less than the other (x).
Since we have two equations, we can use substitution method to solve.
[distribute 1 to (x-5)]
[combine like terms]
[add both sides by 5]
[divide both sides by 2]
Now that we have x, we can plug it into any of the equations to find y.
[plug in x=15]
[subtract both sides by 15]
Finally, we have our answer, x=15 and y=10.

Answer:
5:1
Step-by-step explanation:
Originally the ratio is 20:4
but then it is simplified to 10:2
then 5:1
Answer:1. x<3
2.x>3
Step-by-step explanation:
Number 1.
Step 1: Add 9 to both sides.
7x−9+9<12+9
7x<21
Step 2: Divide both sides by 7.
7x
7
<
21
7
x<3
Number 2.
1x+8>11
Step 1: Simplify both sides of the inequality.
x+8>11
Step 2: Subtract 8 from both sides.
x+8−8>11−8
x>3
leave alike if this help please.
Your answer is D. You just take the feet in a mile (5,280) and divide it by his pace (2.75) feet. You get 1920, which is your answer.
