Answer:
x=4
Step-by-step explanation:
3/4x+ 4 = 7
Subtract 4 from each side
3/4x+ 4-4 = 7-4
3/4x = 3
Multiply each side by 4/3
4/3 * 3/4 x = 3 * 4/3
x = 4
Since one mile is 5280 feet,

The slope of the linear equation is 20 and the y-intercept is 150
<h3>What is a Slope?</h3>
Slope measures how steep a straight line is. It is described as rise over run.
The slope of the linear equation can be found as follows;
He opens the account with $150 and he plans to save $20 each week. Therefore,
let
x = number of weeks
Therefore,
where
y = amount in his account after x number of weeks.
Using the slope intercept equation,
<h3>Slope intercept equation:</h3>
where
m = slope
c = y-intercept
Therefore, the slope of the linear equation is 20 and the y-intercept is 150

Answer: the number of item A that you sold is 11
the number of item B that you sold is 2
Step-by-step explanation:
Let x represent the number of item A that you sold.
Let y represent the number of item B that you sold.
The total number of item A and item B sold is 13. This means that
x + y = 13
The cost of item A is $8 and the
cost of item B is $4. The total amount if money made is $88. This means that
8x + 4y = 88 - - - - - - - - - -1
Substituting x = 13 - y into equation 1, it becomes
8(13 - y) + 4y = 88
104 - 8y = 88
8y = 104 - 88 = 16
y = 16/8 = 2
x = 13 - y = 13 - 2 = 11
