Answer:
103/28
Step-by-step explanation:
Let the number be 'x'
Equation:-
7x - 3/4 = 25
7x = 25 + 3/4
7x = 100/4 + 3/4
7x = 103/4
x = 103/(4 x 7)
x = 103/28
y=x+14 line 1
y=3x+2 line 2
These are both the equation of lines written in slope intercept form
y=mx+b where m is the slope and the point (0,b) is the y intercept.
The first line has a slope of m=1. The 2nd line has a slope of m=3
Since these lines have different slopes, they are not parallel, thus they will cross at some point. What you have to determine is where the lines cross, which will be a point (x,y) that is on both lines.
We already have y solved in terms of x from either equation so we can use substitution to solve the system.
Since y=x+14 from line 1, put x+14 in place of y in the equation of line 2.
x+14=3x+2
solve for x.
Subtract x from both sides...
14= 3x-x+2
14=2x+2
subtract 2 from both sides
14-2=2x
12=2x
divide both sides by 2
6=x
We now have the x value of the common point. Plug the value 6 in for x in one of the original equations and solve for y.
y=6+14
y=20
These two lines cross at the point (6,20) which is a point the two lines have in common.

Answer:
No. Lauren cannot buy the shirt. It costs $48 after the discount.
Step-by-step explanation:
Shirt Cost: $80
Money: $35
Discount: 40%
First, find the amount of the discount by finding 40% of the price. 40% is equal to 0.40 (or 40 divided by 100).
40% of $80 = 0.40 x 80 = $32
Since it's a discount, the final price is the original price minus the discount.
$80 - $32 = $48
So, after a 40% discount, the price is still $48. Lauren only has $35, so it will still be too expensive!
