Answer:
Final answer is x=90,
Step-by-step explanation:
Given equations are:
-x-4y=37 ...(i)
-2x-4y=-53 ...(ii)
multiply (ii) by -1
2x+4y=53 ...(iii)
Add (i) and (iii)
x=90
plug value of x=90 into (i)
-x-4y=37
-90-4y=37
-4y=37+90
-4y=127
Hence final answer is x=90,
Answer:
X=90, y =-127/4
Step-by-step explanation:
Subtract the second equation from the first and you get X+ 0y= 90. Replace x=90 in either equation and you get y= -127/4.
Answer:
pound.
Step-by-step explanation:
We have been given that 5 people share 1/2 pound of trail mix. We are asked to find the amount that each person will get.
To find the amount that each person got, we will divide the total amount of trail mix by total number of people as:
Convert as a multiplication problem:
Therefore, each person will get pound of trail mix.
The elevator at the local mall has a weight limit of 1,800 pounds is
9w ≤ 1800.
Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality. In between, the equal sign is substituted by a less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The elevator at the local mall has a weight limit of 1,800 pounds.
Not more than 9 people allowed in the Elevator.
let the weight of one person be w.
Then, the inequality is
9w ≤ 1800
