Answer:
$1875
Step-by-step explanation:
Given the information:
- An apartment costs: $625 per month
- They require that the cost of rent be no greater that a third of his monthly income
- The must earn at least 3 times the cost of his rent
=> the smallest amount of money that Carlos needs to make per month to be approved to move in:
= 3 times of $625
= 3*$625
= $1875
because 625 is exactly 1/3 of $1875
Hope it will find you well.
1L = 1000 ml
9 ML = 9 * 1000 = 9000ml
9000 is greater than 8456
So 9L is more than 8456ml
Answer:
3.75
Step-by-step explanation:
2.25 divided by 9
= 0.25
then
0.25 * 9
= 3.75
Answer:
(- 2, - 4 ) and (3, 10 )
Step-by-step explanation:
(2)
Given the 2 equations
4x - 7y = 20 → (1)
x - 3y = 10 → (2)
Rearrange (2) expressing x in terms of y, that is
x = 10 + 3y → (3)
Substitute x = 10 + 3y into (1)
4(10 + 3y) - 7y = 20 ← distribute and simplify left side
40 + 12y - 7y = 20
40 + 5y = 20 ( subtract 40 from both sides )
5y = - 20 ( divide both sides by 5 )
y = - 4
Substitute y = - 4 into (3) for corresponding value of x
x = 10 + 3(- 4) = 10 - 12 = - 2
Solution is (- 2, - 4 )
---------------------------------------------------------
(3)
3x + y = 19 → (1)
4x - y = 2 → (2)
Adding the 2 equations term by term will eliminate the y- term
(4x + 3x) + (- y + y) = 19 + 2, that is
7x = 21 ( divide both sides by 7 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (1)
3(3) + y = 19
9 + y = 19 ( subtract 9 from both sides )
y = 10
Solution is (3, 10 )
Someone gave you the wrong answer there is no way that in this equation could anything plus 35 equal 20
