Answer:

False, 6:4 and 18:8 are equal ratios.

Step-by-step explanation:

Given data:

6:4 ≠ 18:8

Explanation.

1. 6:4 = 6/4 = 3/2

2. 18:8= 18/8 = 9/4 = 3/2

Hence proved:

6:4 = 18:8

Step-by-step explanation:

To see whether ratios are equivalent you would try to simplify them by multiplying the number and denominator by the same number in way that they don’t become decimals.

6:4 can be divided by 2 to make its simplest form of 3:2. However 18:8 can also be divided creating its simplest from of 9:4. Since 9:4 and 3:2 aren’t the same they aren’t equivalent ratios.

Can someone help me with this two problems?

ANEK [815]

2x+4y=0

substitute y with 0

2x+4(0)=0

solve the equation

2x+0=0

2x=0

divide by 2 on both sides

x=0

4x+8y=7

substitute y with 0

4x+8(0)=7

solve the equation

4x+0=7

4x=7

divide by 4 on both sides

x=7/4 or x=1 3/4 or x=1.75

3x-7y=-29

2x+2y=6

solve the bottom equation

3x-7y=-29

x=3-y

substitute for x

3(3-y)-7y=-29

solve the equation

y=19/5

now substitute for y

x=3- $\frac{19}{5}$

solve for x

x=-4/5

the possible solution of the system is the ordered pair

(x,y)=( $-\frac{4}{5} ,\frac{19}{5}$ )

Paul is 20 years old. He is four times older than his sister.

attashe74 [19]

Answer: Paul will be 30 years old

Step-by-step explanation:Let the age of her sister be x, then from the given data

=> 4x = 20

=> x = 5 years

The age of her sister is 5 years

In the second case, paul is twice as old as his sister

=> Age of paul = 2(x)

=> Age of paul = 10 years

Paul will be 10 years old when he is twice as old as his sister

What is the length of the side of a right triangle that has a side length of 7 cm and a hypotenuse that measures 25 cm?

Elenna [48]

It would be: 25² = 7² + b²
b² = 625 - 49
b = √576
b = 24

In short, Your Answer would be Option B
