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

If angle p is right angle and angle p and angle q are supplementary then what is angle q
Schach [20]
Right angle (angle p) = 90°
supplementary means total equals 180°
so 90° + q = 180°
subtract 90° from both sides
q = 90°

Solve for x. <br>a.5, <br>b.<br>c.9<br>d.10
Liula [17]
Your proportion should look something like this

\frac{x}{6} =  \frac{6}{4}

After cross multiplication, you should end up with this equation

4x=36

After dividing 4 on both sides, you should get that x=9

There are 24 boys in a class, and 2/3 of the students in the class are boys. How many students are girls ?
tresset_1 [31]

Answer:

12 girls.

Step-by-step explanation:

24 ÷ 2 = 12

(This is divided to find out 1 part of the whole class as ⅓)

⅓ = 12

1 (whole) take away ⅔ = ⅓

Since ⅔ + ⅓ = 1

⅓ = fraction of girls in class

1 part = 12

So ⅓ = 12 girls out of 36 total students

Hope this helps. :)
