First you set and equation for length which is three times width
l=3w
The substitute in the perimeter, p, into the equation for perimeter which is p=2l+2w
88=2l+2w
Then substitute in length, l, with the equation previously created: l=3w
88=2(3w)+2w
Multiply 2 and 3w
88=6w+2w
Combine like terms: 6w+2w
88=8w
Divide to get the value for w
w=11
Since you figure the value for w, 11, you can plug it into the equation for length which is l=3w
l=3(11)
When you do you get
l=33
So the length is 33 and the width is 11
I can't subtrect 7 from 95, but I can subtract 7 from 95. 95-7=88
Answer:
the tax on a $90,000 salary is: $5175
Step-by-step explanation:
Given that the person earns a $90,000 annual salary, you need to use the last of the brackets , the one that reads "<em>17,001 and up</em>". That is, you need to find the 5.75% of the $90,000 in order to determine the taxes owed.
Recall that 5.75% in math terms is: 5.75/100 = 0.0575
Then the 5.75% of $90,000 is mathematically calculated as the product :
0.0575 x 90,000 = 5175
Therefore the tax on a $90,000 salary is: $5175
2 feet 9 inches + 1 foot 6 inches = 3 feet 15 inches
15 inches = 1 foot 3 inches
3 feet + 1 foot = 4 feet
2 ft 9 inches + 1 ft 6 inches = 4 ft 3 inches
1 yard = 3 feet
4feet 3 inches = 1 yard, 1 foot 3 inches
140+170 = 310 yards
310 + 1 = 311
so it traveled 311 yards 1 foot and 3 inches
