**Answer:**

2:5

**Step-by-step explanation:**

The first step is to write the ratio as it is presented in the question

red marbles : total number of marbles

50 : 125

then divide both sides by their highest common factor (25)

2 : 5

You can set it up like this:

x + 3x = 44

Combine like terms:

4x = 44

Divide both sides by 4:

x = 11.

So, one number is**11**, and the other number (the larger one) is **33**.

Hope this helps!! xx

x + 3x = 44

Combine like terms:

4x = 44

Divide both sides by 4:

x = 11.

So, one number is

"excepted?" I think you meant "expected."

In this problem you need to convert that "7.5%" into a decimal fraction: 0.075.

The increase in population will be 0.075 times p, the current population. You then add that to p, the current population.

But it's easier and faster to multiply p by 1.075. Thus, 1.075p is the correct answer.

QUESTION POSTED AT 22/02/2020 - 06:48 PM

**Answer:**

Christopher bought 3.5 pounds of roasted pistachios and 2.8 pounds of raw almonds.

**Step-by-step explanation:**

From the information given, we can write the following equations:

A+P= 6.3 ①

10A+12P= 70 ②

To resolve them, we have to isolate one of the variables in the first equation and then replace that in the second equation:

A=6.3-P ③

10(6.3-P)+12P=70

63-10P+12P= 70

2P= 70-63

P= 7/2=3.5

Now, that we have found the quantity of roasted pistachios, we can replace that in equation number 3 to find the quantity of raw almonds:

A= 6.3-3.5= 2.8
