x=-3, y=1
Step-by-step explanation:
Given equations are:
2x-3y=-9 Eqn 1
x+y = - 2 Eqn 2
From eqn 2:
Putting x=-y-2 in eqn 1
Hence,
x=-3, y=1

Which of the following represents the amount of money he must earn each week?
x ≥ $52
x > $52
x ≥ $63
x > $63
Answer:
x>52
Step-by-step explanation:
the answer to this equation is 120
Answer:
120
Step-by-step explanation:
The required percent 40% of 120% of x is equal to 0.48 times x.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
To find 40% of 120% of x, we can first find 120% of x, and then find 40% of that result.
120% of x can be found by multiplying x by 1.2:
120% of x = 1.2 * x
Next, to find 40% of the result, we multiply by 0.4:
40% of (120% of x) = 0.4 * (1.2 * x)
So the final answer is:
40% of 120% of x = 0.4 * (1.2 * x) = 0.48x
This means that 40% of 120% of x is equal to 0.48 times x.

Answer:
48 percent
Step-by-step explanation:
Let x be the number. If I understand the wording of the problem correctly, then the equation is this: x + (1/6)x + (5/2)x + 7 = 5/2 .
x = - 27/22 or - 1 5/22 if a mixed number is desired.
