Let no. of shirts be x.
Chris -- 7x
Brian --- 5x
132x/(7x+5x) = 11
x=11
Chris sold (11 x 7) shirts = 77 shirts
Brian sold (11 x 5) shirts = 55 shirts
None becauase 1 meter is 3 feet so 2 meters is equal to 6 feet.
Distribute the 3 to the parentheses. Q=3r+3/r
Next multiply both sides by r to get rid of the division sign.
Qr=3r+3
Subtract 3r on both sides and you get Qr-3r=3
Since both numbers have an r in it, we can factor out the r
r(Q-3)=3
Then we divide Q-3 on both sides
r=3 / (Q-3)
Answer:
x−4
Step-by-step explanation:
Answer:Is an estimate of the average grams of salt used in 2012
Step-by-step explanation: Let
x ---> the number of years since 2012
f(x) ---> is the total amount of salt ingested in grams
we have
This is a linear equation in slope intercept form
where
The slope is equal to
The y-intercept or initial value is equal to
The y-intercept is the value of the function f(x) when the value of x is equal to zero
In this context, the y-intercept is the average amount of grams of salt ingested in the year 2012
The exact value of the average amount of grams of salt ingested in the year 2012 is 3,554 grams (see the data in the table)
Compare the exact value with the y-intercept
therefore
3,548 grams Is an estimate of the average grams of salt used in 2012
