Answer:

There were 62 deaths

Step-by-step explanation:

In this question, we are asked to calculate the number of robberies in 2012.

From the question we can identify that the number of robberies were up 50% to 93. What this means is that the number is simply 150% of the old number.

Now, let’s represent the number of deaths in 2012 by x

Mathematically;

150% of x = 93

150/100 * x = 93

150x = 93 * 100

150x = 9300

x = 9300/150

x= 62

This means there were 62 deaths in the year 2012

Answer:

There were 62 robberies in Springfield in 2012.

Step-by-step explanation:

Let's marked (named) robberies in 2012 with x, which is worth 100%

93 robberies in 2013 worth 100% + 50% = 150%

Now we will make proportion

x : 93 = 100 : 150

When we multiply external and internal members we get

x/93 = 100/150

Cross multiply

150 x = 93 × 100

150x = 9300

x = 9300/150

x = 62 robberies in 2012

x will represent the first unknow number

6x will represent the second number

the two numbers together will equal 21

6x + x = 21  combine like terms

7x =21  divide both sides by 7

x =3


Hope that helps.

I need 50 gallons of milk replacer for calves and the powder mixture says it's 6.25 oz for 5 gallons how many oz of powder do I
zubka84 [21]

Answer:

62.5 oz

Step-by-step explanation:

We can use the ratio proportion method:

x:50::6.25:5

x = (50x6.25)/5

OR a more simple method is to do this:

5 gallons of milk require 6.25 oz. How many oz of powder do I need to get 10x that amount? Since 50 is 10x5, you do the same thing for 6.25, and get 62.5

Mr. Rivera can grade 18 math teat in 15minutes. What is the teachers unit rate?
Andru [333]

In this question, you're trying to find the unit rate in which the teacher can grade tests.

A unit rate is another word for "rate of change".

This means that we have to find how many tests the teacher could grade in 1 minute.

To find the unit rate, divide 18 by 15

18 ÷ 15 = 1.2

This means that Mr. Rivera can grade 1.2 tests in 1 minute.

Answer:

1.2 tests
