Answer:
The correct answer is: She bought 2 dress shirts and 5 t-shirts
Step-by-step explanation:
Let's marked dress shirts with x and t-shirts with y.
Now we will make equations to solve this problem:
x + y = 7 => y = 7 - x
40 x + 8 y = 120
When we replace y = (7 - x) in the previous equation we get:
40 x + 8 (7 -x) = 120 40 x + 56 - 8 x = 120 => 32 x = 120 - 56 =>
32 x = 64 => x = 64/32 = 2 => x = 2
y = 7 - x = 7 - 2 = 5 => y = 5
x = 2 dress shirts
y = 5 t-shirts
God with you!!!
Yes (3, 28) is a solution for the equation.

Answer:
5
Step-by-step explanation:
Finding the distance, midpoint, slope, equation and the x y-intercepts of a line passing between the two points p1 (7,6) and p2 (2,6)
The distance (d) between two points (x1,y1) and (x2,y2) is given by the formula
d= √((X2-X1)2+(Y2-Y1)2)
d = √(2-7)2+(6-6)2
d = √((-5)2+(0)2)
d= √(25+0)
d = √25
The distance between the points is 5
Step-by-step explanation:
c²=24²+45²=2601
so c=51
