This is not the answer, but I want to tell you that I can't see what the problem says. I would help you, but I can't.
Answer:
Lev is incorrect because (9, 4) is not a solution to the equation.
Step-by-step explanation:
We are given the equation: 3y - 2x = 19
When we are to check if an ordered pair is a solution to an equation, we substitute the pair in the equation and compare the RHS and LHS.
If they come to be equal then we can say that the given pair is indeed a solution to the equation.
So, here, RHS = 19
LHS = 3(4) - 2(9) = 12 - 18
= -6
19
i.e., LHS ≠ RHS
So, we can say that (x, y) = (9, 4) is not a solution to the given equation.
Answer:26
Step-by-step explanation:
85*2=170
170+64+x=360
234+x=360
x=126
Answer:
Step-by-step explanation:
The sum of those numbers is 14. Let's divide 14000 by 14 to get the number of parts (each part will be an investment in dollars) and we get 10,000. So if a person invests 2 parts, he invests 2(10,000). A person that invests 5 parts invests 5(10,000), and likewise for the person investing 7 parts: 7(10,000). That gives us 20,000 + 50,000 + 70,000 = ?
(140,000)
The difference in investment between the largest and the smallest is 50,000
Answer:
2 ( x+3) (x+1)
Step-by-step explanation:
2x^2+8x+6
Factor out a 2
2(x^2 +4x+3)
Factor in side the parentheses
What multiply to 3 and adds to 4 (3(1=3 3+1 =4)
2 ( x+3) (x+1)
