Answer:

p = - 8

Step-by-step explanation:

we have to subtract by the number 18p from each of your sides

Like: 10p + 5 - 18p

= 18p -3 -180

This gives us: -8p + 5 = -3

Nextly, we have to subtract by 5 on each of your sides

Like: -8p + 5 - 5

= -3 - 5

This gives us: -8p = -8

Now we have divide by the -8 on each of your sides:

Like: -8p ÷ -8

= -8 ÷ -8

Answer: p = 1

Step-by-step explanation:

10p + 5 = 18p -  \frac{6}{2} \\ collecting \: like \: terms \:  \\ 10p - 18p =  -  \frac{6}{2}  - 5 \\ 8p =  -  \frac{11}{2}  \\ 8p =  - 5.5 \\ p =   -  \frac{5.5}{8}  \\ p = 0.68

Lucy is raising money for a school trip by selling lollipops and bags of
sukhopar [10]
<h3>16 lollipops and 9 bags of chips are sold</h3>

<em><u>Solution:</u></em>

Let "x" be the number of lollipops sold

Let "y" be the number of bags of chips sold

Cost of 1 lollipop = $ 1.50

Cost of 1 bag of chip = $ 1.75

<em><u>Yesterday Lucy made $39.75 from selling a total of 25  lollipops and bags of chips</u></em>

Therefore,

x + y = 25

y = 25 - x -------- eqn 1

<em><u>Yesterday Lucy made $39.75</u></em>

Therefore,

number of lollipops sold x Cost of 1 lollipop + number of bags of chips sold x Cost of 1 bag of chip = 39.75

x \times 1.50 + y \times 1.75 = 39.75

1.5x + 1.75y = 39.75 -------- eqn 2

<em><u>Substitute eqn 1 in eqn 2</u></em>

1.5x + 1.75(25 - x) = 39.75

1.5x + 43.75 - 1.75x = 39.75

0.25x = 4

<h3>x = 16</h3>

<em><u>Substitute x = 16 in eqn 1</u></em>

y = 25 - 16

<h3>y = 9</h3>

Thus 16 lollipops and 9 bags of chips are sold

Please solve for a, b, and c
rusak2 [61]

The table is:
Number of washes denoted by x: 0, 8, 12
Amount left on card denoted by y: 30, 18, 12
 
a.       Write an equation that shows the amount of dollars left on the card
Solution:
18 – 30 divided by 8 – 0 = -12/8
On simplest form is -3/2
 
The equation is y = -3/2x + 30
 
b.      Explain the meaning of the negative slope above.
As the number of car washes increase, the dollars left on the card decreases.
 
c.       What is the maximum value of x?
0 = -3/2x + 30
2/3 x 3/2 x = 30/1 x 2/3
Cancel 2/3 x 3/2 and reduce 30 by 3 we get 10, 10 x 2
x = 20
