Make bottom numbers same
they should be 40
to kee p fractions the same multiply topo and bottom by same number
3/8 times 5/5=15/40
1/5 times 8/8=8/40
15/40+8/40=23/40
7 - 3 = 4....so there is a $ 4 profit for every unit sold
4x = 3600
x = 3600/4
x = 900....so 900 units have to be sold to earn a profit of $ 3600
Answer:
it is d, step 1: 14x - 21; step 2: 14x=22
Step-by-step explanation:
7(2x-3)=1 1. multiply 7 with (2x) and (-3)
14x-21=1 2. +21 on both sides
14x= 22 3. /14 on both sides
x=1.8
but I will say d is the correct answer
For a line to be perpendicular to the x-axis in a 2 dimensional space, it must be composed of points with the same x coordinate and varying in the y coordinate.
X is, therefore, a constant and since the line goes through (-3,1), the equation we are looking for is:
X = -3
