Answer:
The area of the room is 125 square feet because 12.5 times 10=125 square feet. As a result, you will spend $187.5 for it cost $1.5 to buy one square foot of carpet, and now we need 125 square feet to cover the room which 125 times 1.5 to get 187.5. Hope it help!
Step-by-step explanation:
Let :
T = Theresa age
H = her brother
We know :
T = H - 14
T + H = 35
Substitute T
H -14 + H = 35
2H - 14 = 35
2H = 49
H = 49/2 = 24.5
Since we know H = 24.5 we then can substitute it to either equation.
T = H - 14
T = 24.5 - 14
T = 10.5
Theresa is 10.5 years old
Her brother is 24.5 years old
Answer:
y= 1/2x + 1
Step-by-step explanation:
Refer to y=mx+b, m=slope and b= y-intercept
First, you find the slope: you can find the slope by finding the rise over run between two points. Rise= 1, Run=2. The slope is rise/run (rise over run), so the slope would be 1/2 (one half).
Next, find the y-intercept. It is where the line touches the y-axis. Here, it would be 1.
Finally, put these in y=mx+b form:
y=(slope)x+(y-intercept) ---> y= 1/2x + 1
I tried my best to explain everything, I hope you found this helpful!
