<h3>Let's start by finding a ratio of Y to X</h3>

$\frac{150}{10} = \frac{300}{20} = \frac{450}{30} = \frac{600}{40} = 15$

$for \: x = 15y$

$50x = 50(15) = 750.00$

A+b/a-b=5/3 what are the following ratios? 3a:2b

Papessa [141]

Answer:

3 a : 2 b = 6 : 1

Step-by-step explanation:

$\frac{a + b}{a - b}$ = $\frac{5}{3}$

3 ( a + b) = 5 ( a - b)

3 a + 3 b = 5 a - 5 b

5 b + 3 b = 5 a - 3 a

8 b = 2 a

2 a = 8 b

a = 4 b

3 a = 3 × 4 b

3 a = 12 b

3 a: 2 b = 12 b : 2 b

3 a : 2 b = 6 : 1

Answer:

C) 6 feet

Step-by-step explanation:

The diagram is shown in the attachment.

Using the Pythagoras Theorem,

$x^2=4^2+4^2$

$x^2=16+16$

$x^2=32$

We take positive square root to obtain

$x=\sqrt{32}$

$x=4\sqrt{2}$

x=5.66ft

Rounding to the nearest feet we have x=6ft

What are some real life situations using system of equations?

OlgaM077 [116]

Bob's car rental company makes you pay 10 dollars per day you rent the car and a 30 dollar insurance fee

joe's car rental company makes you pay 30 dollars per day you rent the car and a 10 dollar insurance fee

how many days do you need to rent a car for the cost for renting both are the same

bob=10x+30
joe=30x+10
set each to each other
10x+30=30x+10
subtract 10x
30=20x+10
subtract 10
20=20x
divide both sides by 20
1=x
you need to rent 1 day for them to be equal
