What’s a equivalent ratio

Ratios that are equivalent to each other are considered equivalent ratios. For example, 2:6 is equal to 6:18

Think of equivalent ratios as equivalent fractions, or fractions that are equal to each other.

An example of an equivalent ratio would be
1:2(or 1/2) = 2:4(or 2/4).

These two ratios are exactly the same, though they may not look anywhere near the same.

One way we could determine if two ratios are equivalent or similar, is by dividing the bigger side by the smaller side ( in our example, that would be 2/1 = 2), then divide the other side of the ratio by the same side ( 4/2 = 2 )

Since they are both equal to 2, we can say that they are the same, or equivalent.

I know this is a lot of information, but I hope this helped!

Answer:

A

Step-by-step explanation:

Equation

300 ( 1 + x) = 420

Explanation

You start with 300. What fractional amount do you need to increase the original amount up to 420

Solution

Divide both sides by 300

300(1 + x)/300 = 420/300

1 + x = 1.4    

Subtract 1 from both sides.

1 - 1 + x = 1.4 - 1

x = 0.4

But as a percent this number is 0.4 * 100 = 40%

Answer

40% which is A

Which expressions are equivalent to the one below? Check all that apply.
V125BC [204]

Answer:

Step-by-step explanation:

The given expression is 10x.

We have to check which of he given options on simplification gives the same given expression.

(A) The expression is:

=\frac{50x}{5x}

=10

which is not equivalent to the given expression, thus this option is incorrect.

(B) The expression is:

=10(10x)-1

=100x-1

which is not equivalent to the given expression, thus this option is incorrect.

(C) The expression is:

=10(10x)+1

=100x+1

which is not equivalent to the given expression, thus this option is incorrect.

(D) The expression is:

=\frac{50x}{5}

=10x

which is equivalent to the given expression, thus this option is correct.

(E) The expression is:

=(\frac{50}{5})x

==10x

which is equivalent to the given expression, thus this option is correct.

(F) The expression is:

=x^5

which is not equivalent to the given expression, thus this option is incorrect.

-----------------> 10x - 3 - 2x = 4
Elina [12.6K]

Answer:

x=\frac{7}{8}

Step-by-step explanation:

10x-3-2x=4

First, collect and rearrange the like terms.

10x-3-2x=4

8x-3=4

8x=4+3

Then, solve the equation:

8x=4+3

8x=7

x=\frac{7}{8}

So, the answer is x=\frac{7}{8}. Hope my solution and explanation can help you. Thank you!

If you still cannot get the point, you can ask me anytime.

PLEASE HELP <br> Match each expression to the scenario it represents
joja [24]

Answer:

i)

0.79m

ii)

1.21m

iii)

7/5m

iv)

3/5m

Step-by-step explanation:

i)

The price of a USB memory stick selling at a 21% discount off its marked price (m)

The marked price m represents 100% of the value of the USB memory stick. Offering a 21% discount off the marked price will mean that the USB will be selling at;

(100 - 21)% of the marked price m

=79% of m

= (79/100)*m

= 0.79m

ii)

The price of a CD that sells for 21% more than the amount (m) needed to manufacture the CD.

The amount (m) needed to manufacture the CD would represent 100% of the value of the CD. Selling the CD for 21% more than the amount (m) needed to manufacture the CD will imply that the selling price is;

(100+21)% of m

= 121% of m

= (121/100)*m

= 1.21m

iii)

The final value of a painting after its initial value, m, increases by 2/5.

The initial value of the painting is given as m. The value of the painting is said to increase by 2/5 which means that the increase in its value would be;

2/5 of m

=2/5 * m

=2/5m

The final value of the painting will thus be;

initial value + increase in value

=m + 2/5m

= m(1+2/5)

=7/5m

iv)

The total number of markers that Nancy has if she gives away 2/5 of her m markers to Amy.

Initially, Nancy had a total of m markers. By giving away 2/5 of her markers to Amy, her markers reduced by;

2/5 of m

=2/5*m

=2/5m

The new number of her markers will be given by;

initial numbers - total given to Amy

= m - (2/5m)

= m(1 - 2/5)

=m(3/5)

=3/5m
