Answer:
The total allowance is $18.5, and the amount spent daily is $3.2
Step-by-step explanation:
let T and x represent the total allowance and the amount spent daily respectively.
It was started that the amount remaining after 2 days is $12.10 , which implies the person has spend an equal amount for 2 days
T - 2x =12.10 (equation 1)
It was started that the amount remaining after 5 days is $2.50 , which also implies the person has spend an equal amount for 5 days
T - 5x =2.5 (equation 2)
subtract equation 2 from 1
T - 2x -( T - 5x ) = 12.10 -2.5
T - 2x -T + 5x = 9.6
3x =9.6
Divide both side by 3
x = 9.6/3 =3.2
from equation 1
T - 2x =12.10
T = 12.10 + 2x = 12.10 + 2*3.2
= 12.10 + 6.4 = 18.5

Answer A
Answer: 45.168
Step-by-step explanation: First find 941 x 48 = 45168 then put the decimal point at the thrid digit as the decimal in 9.41 is in the 2nd digit and 1st in 4.8 so 2 + 1 = 3 so the answer is 45.168
Answer:
Step-by-step explanation:
1. Convert to slope intercept form (y=mx+b)
2. Find slope (the 'm' in mx)
3. Find slope of perpendicular line
So for the first question:
Convert to slope Intercept form if necessary:
3x+4y=12
4y=12-3x<<Subtract by 3x
y=3-<u>3/4</u>x<<Divide by 4
Find slope
y=3-<u>3/4</u>x
3/4 is the slope
Find slope of perpendicular line
To find the slope of a perpendicular line, you just have to take the reciprocal of the original slope and take the opposite sign.
Here is what I mean:
3/4<<original slope
4/3<<reciprocal
-4/3<<opposite
So for the first question -4/3 is the answer.
Now you can do the rest! Hope this helps!
