Answer:
x+0.05x=3.15 which has one solution
Step-by-step explanation:
Complete question below:
Joshua sells a pack of pens for 3.15 which is 5 percent more than he pays for them. which equation will help find x, the amount he pays for a pack of pens? how many solutions will this equation have? x+0.05x=3.15, which has infinitely many solutions x+0.5x=3.15, which has one solution x+0.05×=3.15 which has one solution 0.05×=3.15, which has no solution
Let
x= the amount Joshua pays for a pack of pen
5% of x more than he paid for them
=0.05x more
Buying price=0.05x + x
Selling price=3.15
Equate buying and selling price
0.05x + x = 3.15
1.05x=3.15
Divide both sides by 1.05
1.05x / 1.05 = 3.15/1.05
x=3
The equation is 0.05x+x=3.15
The answer is:
x+0.05x=3.15 which has one solution
For this case we must solve the following proportion:
Multiplying by 5 on both sides of the equation we have:
Subtracting 2 from both sides of the equation:
ANswer:
2,4,6,8,10,12,14,16,18,20,22,24!.. so 2 x 12= (24).....
The formula for the area of a trapezoid is (B+B)H/2 it is going to be (10+12)*8/2=58
the area of the trapezoid is 58<span />
