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
3 outa 12 are 5
so we divide 150 by 12
Hence Getting 25.
So 25 Is the Answer

Answer:
f(g(x))= x-2
Step-by-step explanation:
f(g(x))= (x-4)+2 -plug g(x) into the place of x in the f(x) function
f(g(x))= x-4+2 -parentheses aren't needed
f(g(x))=x-2 -combine like terms
Answer:
A=6
Step-by-step explanation:
If the area is enclosed by x(0,4) and y(3)
That means the area is a triangle
h(height) =3 b=4 c**2=a**2+b**2 c=5
The area of an equlateral triangle is A=h*b/2
A=3*4/2=12/2
Well if you add all the numbers together, the total is 14. So 4/14 chance of pulling out a red marble.
