Answer:

100 more silver cars

Step-by-step explanation:

OK so first I made a fraction being 40/20 so green cars over silver cars. Then i multiplied the fraction by 1/6, which gave me 40/120 and to make sure that it was a proper fraction. I found a common denominator. I found that the common denominator was 40. So divided both sides by 40. (40/40=1) (120/40=3) causing the answer to be 100 silver cars because you had to have 120 silver cars and 40 green cars to have a 1 to 3 ratio

Hope this help

Answer: 5%

Step-by-step explanation:

Aditi invested 100,000 Rupees and after 2 years had 10,000 Rupees in interest.

Interest percent is therefore:

= Interest / Principal

= 10,000/100,000

= 10%

This is for 2 years though so you need to find for a year:

= 10%/2

= 5%

Answer: 1/12 of the whole pizza

Step-by-step explanation:

Someone cut a whole pizza into 3 pieces.

This means that the pizza was cut into 1/3 slices each.

She then gave her 4 children one of these sections to share equally.

The part each child got is:

= 1/3 ÷ 4

= 1/3 * 1/4

= 1/12 of the whole pizza

Note: When dividing fractions, you can multiply the first fraction by the inverse of the second fraction to find your answer.

Answer:

[tex]4P+2G=96\\3P+1G=60 or 3P+G=60[/tex]

Step-by-step explanation:

Given in the question:

a) A family paid $96 for 4 pool passes and 2 gym memberships.

b) Later that day, an individual bought pool passes for herself and 2 of her friends, and 1 gym membership for her. She paid $60.

Let's write the system of equations for each purchase  that happened in the scenario.

Let,

P=Price of each pool passes

G= Price of each gym membership

We get,

a) A family paid $96 for 4 pool passes and 2 gym memberships:

[tex]4P+2G=96[/tex]

b) Later that day, an individual bought pool passes for herself and 2 of her friends , and 1 gym membership for her. She paid $60:

[tex]3P+1G=60[/tex]

Therefore, the equations generated in the scenario were:

[tex]4P+2G=96\\3P+1G=60 or 3P+G=60[/tex]

Where,

P=Price of each pool passes

G= Price of each gym membership

Answer:

angle P congruent to angle N

Step-by-step explanation:

You know the angles at Q are congruent.

If angle P is congruent to angle N, then angle R is congruent to angle D.

Then both triangles are similar.

Step-by-step explanation:

Supplementry means which add up to 180°

Now, let's take one of them as x

And the other as x - 10

Now let's add : x + (x - 10) = 180°

2x - 10 = 180°

2x = 180 + 10

2x = 190

x = 190/2

x = 95

X = 95

x - 10 = 95 - 10

So, = 85

The 2 numbers are 95, and 85

Lets check!

95 + 85 = 180!

So therefore they are supplementry so it's right!

Hence he will save $4 for the purchase

Answer:

Dimensions of rectangle are [tex](5x+2)\:and\: (2x-3)\\[/tex]

Step-by-step explanation:

Area of rectangular knitted blanket = [tex]10x^2-11x-6[/tex]

We need to find the dimensions of blanket.

If we need to find the dimensions, we need to find the factors of area.

Factoring:  [tex]10x^2-11x-6[/tex]

We will break the middle them -11x

Now, finding factors

[tex]10x^2-11x-6\\10x^2+4x-15x-6\\2x(5+2)-3(5x+2)\\(5x+2)(2x-3)\\[/tex]

So, factors of [tex]10x^2-11x-6\\[/tex] are [tex](5x+2)(2x-3)\\[/tex]

So, dimensions of rectangle are [tex](5x+2)\:and\: (2x-3)\\[/tex]

Answer:

Answer:

Step-by-step explanation:

[tex] \frac{6}{x - 1} = \frac{4}{x + 2} [/tex]

[tex]6x + 12 = 4x - 4[/tex]

[tex]6x - 4x = - 12 - 4[/tex]

[tex]2x = - 16[/tex]

[tex]x = - 8[/tex]
