How would you solve -7x-4y=16

Answers

Answer 1

Answer: so one easy way is to make the equation equal to only one place holder so
-7x-4y=16
add 7x to both sdies
-4y=16+7x
multiply both sides by -1
4y=-16-7x
divide both sides by 4
y=-4-7/4x
subsitute values for x and get values for y
exg
if x=0 then y=-4
if x=1 then y=-5 3/7
etc

choose two additional data values for the given data set so that the given data set is true A. the median is 8 4,12,14,10_,_ B. The median is 11 4,12,14,10,_,_ C. The mean is 10 4,12,14,10,_,_

Answers

first step in finding the median is ordering the numbers 1. 4,10,12,14. Then you find out the number in the middle.
step 1: 4,10,12,14
step 2: now, take out the first number so 10,12,14
Step 3: now take out the last number so 10,12
step 4: since there are two middle numbers, you average them. If you didn't know already, all you have to do to average them is add the two numbers together then divide them by two so 10+12=22 /2=11
now you want to find two numbers that if averaged with 11, make 8. so you could do two . final answer is 4,5,5,10,12,14

1. 4,12,14,10,5,5
2. 4,12,14,10,12,10

now mean is just average so what you would do is just add all your numbers up and divide by the amount of numbers you added.

The football team has a total of 50 jerseys. There are 30 medium-sized jerseys. What percent of the jerseys are medium-sized jerseys

Answers

$(medium\ sized)/(total\ number \ of\ jersey)*100\%=\n(30)/(50)*100\%=(3000)/(50)\%=60\%\n\nMedium \ sized\ jerseys\ are\ 60\%\ of\ all.$

Final answer:

60% of the jerseys are medium-sized. This is found by dividing the number of medium-sized jerseys (30) by the total number of jerseys (50), getting a result of 0.6, and then multiplying this by 100.

Explanation:

To find out what percent of the jerseys are medium-sized, you would need to divide the number of medium-sized jerseys by the total number of jerseys and then multiply by 100. Here's the calculation step-by-step:

Divide the number of medium-sized jerseys (30) by the total number of jerseys (50).
The result of this calculation is 0.6.
Multiply 0.6 by 100 to get the percentage.
This gives a result of 60.

So, 60% of the jerseys are medium-sized.
