5{-3.4k-7} + {3k+21}

Answers

Answer 1

Answer: First step is to do distributive property.

so you multiply 5 by -3.4k and -7

your equation now is -17k-35+(3k+21)

Then you add like terms

add -17k+3k to give you -14k-35+21

then you add like terms again

add -35+21 to give you -14

so now your equation is -14k-14

So that is your answer simplified

A survey found that 3 out of 7 people in a community job on a regular basis. If there are 3150 people in the community, What is the reasonable prediction for the number of people who would jog regularly?

Answers

The requried reasonable prediction for the number of people who would jog regularly in the community is 1350.

What is proportionality?

Proportionality is the relationship between two or more sets of values, and it describes how these values are related to each other.

If 3 out of 7 people jog on a regular basis, then the fraction of people in the community who jog on a regular basis is:

3/7

To predict the number of people who would jog regularly in the community, we can multiply this fraction by the total number of people in the community:

(3/7) * 3150 = 1350

Therefore, a reasonable prediction for the number of people who would jog regularly in the community is 1350.

the ratio of basketballs to footballs in coach Farrell's pe class is 10.:3. if there are 52 total balls in the class, how many basketballs and football are there

Answers

Answer:

There are 40 basketballs and 12 footballs

Step-by-step explanation:

basketballs : footballs

10 :3

Multiply each side by x because we need to keep the ratio the same

10x : 3x

The total is 52

10x+3x= 52

Combine like terms

13x = 52

Divide by 13

13x/13 =52/13

x = 4

basketballs : footballs

10*x : 3*x

10*4 : 3*4

40 : 12

There are 40 basketballs and 12 footballs

There are 40 basketballs and 12 footballs.

What does "What scale would be appropriate to graph the data?" mean?

Answers

I think it means which graph is the best at representing the data or data set.

For example if you were to graph the population of an animal you would use a line graph to represent the data

If you were determining how much percentage you would get a job you would use a pie graph. Etc
