Answer:

Step-by-step explanation:

Florence \ washed \ 3\  cars \  and\  earned\  = \$ x\\\\

Cost\ of \ washing \ one \ car = \frac{x}{3}

Anona \ washed \ 5 \ cars \ and \ earned \ 16 \ more \ than \ Florence = x + 16

Cost\ of \ washing \ one \ car \ by \ Anona = \frac{x +16}{5}

 \frac{x}{3} = \frac{x + 16}{5}\\                    [ \ cross \ multiply \ ]

5 \times x = 3 \times( x + 16)\\\\5x = 3x + 48\\\\5x - 3x = 48\\\\2x = 48\\\\x = 24

Cost \ of \ washing \ one \car = \frac{x}{3} = \frac{24}{3} = \$ 8

Therefore ,

                 Florence earned $24

                 Anona earned 24 + 16 = $40  

                 Caragh Washed 4 cars, so Caragh earned = 8 x 4 = $32

Im doing decimals greatest to least and i need help with number 12 and 13
erma4kov [3.2K]

(I know there isnt any real problem here to solve, but heres a tip on how to solve greatest to least with decimal problems)

1. Just because a number looks big, doesn't mean it is big

Example: 1.00000000000001 < 1.1

just look at the numbers ^ and dont just hastily read it over assuming that 1.1 is smaller because it "has less digits"

2. Negative numbers are... opposite. and they are less than positive numbers

-3.4 > -4.1

Why is this? Well, if you look on a line, with the point 0 in the middle, you can see that -3.4 is not as far away from 0 as -4.1 is. So the idea is to apply opposite logic for negative numbers

I hope these tips helped!! :D

Find the equation of the line passing through the points (3,-2) and (3, 4).The answer is x = 3. I'm just wondering how my textbo
Leviafan [203]

Given two points. we can find the equation of a line passing through the points

The formula to be used is:

\frac{y_2-y_1}{x_2-x_!}=\frac{y-y_1}{x-x_!}

where

x_1=3,y_!=-2,x_2=3,y_2=4\frac{4-(-2)}{3-3}=\frac{y-(-2)}{x-3}

=>

\frac{6}{0}=\frac{y+2}{x-3}

The next step is to cross multiply

6(x-3)=0(y+2)

=>

6(x-3)=0

Divide both sides by 6 and make x the subject

x=3

What is a1? what is d? what’s the equation? what is a7? what is a59?
Zina [86]
Answer:

a1 = 2

d = 3

an = 2 + (n - 1) * 3

a7 = 20

a59 = 176

Steps:

a1 is the initial value (when n equals 1), and since there are 2 crosses, it is 2.

d is the added value to each amount of crosses. And since the second amount is 5 and the third amount is 8, we can determine that each n is adding 3 crosses, therefore making d = 3.

The equation is simply plugging in the values for a1 and d.

A7 is simply plugging in 7 for n in the equation and solving for it. So;

a7 = 2 + (7 - 1) * 3

a7 = 2 + 6 * 3

a7 = 2 + 18

a7 = 20

And same thing as the last for 59 except substitute 59 in for where you put 7;

a59 = 2 + (59 - 1) * 3

a59 = 2 + 58 * 3

a59 = 2 + 174

a59 = 176
