H-human a-horse
h+a= 72
2h+4a=192
then do h=72-a
substitute that into the second equation
2(72-a)+4a=192
multiple out
144-2a+4a=192
2a=48
a=24
substitute a into the first equation
h+24=72
h=48
humans- 48
horses- 24
Answer:
a.) 26< a <u>28 </u>
b.) 4
Step-by-step explanation:
a.) After looking at the age in years collum you can notice that all of ages have a difference of 2. With this you can infer that the missing number is 28.
b.) To find the mean add up all the numbers in the frequency column.
3+2+7+8+0=20
Divide that by the amount of numbers. There are 5 numbers so 20/5=4.
Hope this helps!
Company A has a sales position with a yearly salary of $42,000. Company B has a similar sales position with a slary of $39,000 plus 1% conmission on yearly sales.
Let x be the amount of yearly sales
Company A has a sales position with a yearly salary of $42,000.
yearly salary = 42,000
Company B has a similar sales position with a salary of $39,000 plus 1% commission on yearly sales.
1% is 0.01
yearly salary = 39,000+ 0.01x
yearly sales is the salary at company A greater than the salary and conmission at company B
A > B
42000 > 39000+ 0.01x
We solve the inequality
39000+ 0.01x < 42000
Subtract 39000 on both sides
0.01x < 3000
divide by 0.01
x> 300,000
For yearly sales > $300,000, the salary at company A greater than the salary and commission at company B
Answer:
10.8 feet
Step-by-step explanation:
Multiply 4/5 by 2 on the top and bottom. Then you'll get 8/10 which is 0.8 as a decimal
120,000 renamed to ten thousand (10,000) is twelve ten thousand. Ten thousand in number form is 10,000. When you divide 120,000 (one hundred and twenty thousand) by 10,000 (ten thousand) you get 12. 120,000 (one hundred and twenty thousand) /10,000 (ten thousand) = 12. So there are twelve ten thousands in 120,000.
