Answer:
x=237/7 and y=-199/7
Explanation:
Multiply the second equation by 2, then add the equations together.
(−2x+3y=−153)
2(x+2y=−23)
Becomes:
−2x+3y=−153
2x+4y=−46
Add these equations to eliminate x:
7y=−199
Then solve 7y=−199 for y:
7y=−199
(Divide both sides by 7)
y=−199/7
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
−2x+3y=−153
Substitute −199/7 for y in−2x+3y=−153:
Add 597/7 to both sides
Divide both sides by -2
Answer:
5/9
Step-by-step explanation:
Firstly we need to find an area of a single tile:
6 * 14 = 84 square inches
Now we just need to find out how many tiles of 84 square inches will fit in an area of 8900 square inches:
8900 ÷ 84 = 105,952380952381
Assuming we can't cut a tile into pieces, we may round the result to 106.
Answer: The least number of tiles Jared will need is <u>106</u>.
Happy to help :)
after 1 yr- 3905.25 km2
2 yrs- approx. 3719.75 km2
3 yrs- approx. 3543.06 km2
4 yrs- approx. 3374.77 km2
5 yrs- approx. 3214.47 km2
The full decimal for the 5 yr mark is 3214.46557 km2 (not sure if you needed it)
To solve you would convert 4.75% into .0475 as a decimal, then subtract that from 1 (which acts as 100%) and you get .9525, then just multiply that by 4100 and each number that results from that ;)
