Answer:
x + y = 162 and x = 2y - 6
Step-by-step explanation:
Let the total wins be x
Let the total loss be y
If a baseball team's total wins and losses for one season is 162, this can be expressed as;
x + y = 162 ....... 1
If the number of wins is 6 less than 2 times the number of losses, this is expressed as;
2 times the number of losses = 2y
6 less than 2 times the number of losses = 2y - 6
Now, If the number of wins is 6 less than 2 times the number of losses this is expressed as;
x = 2y - 6 .... 2
Hence the required system of equation are;
x + y = 162 and x = 2y - 6
The formula for direct variation is y = kx<span> where k </span>≠ 0
y = 9/x is an inverse relation
S.I = PxRxT / 100
Therefore
S.I.= $10000x3x6/100
=$900
26 by 9
Area = L*W
Area = 26 * 9
Area = 234 square feet but there are 2 such walls
Area = 234 * 2
Area = 468 square feet total for these walls.
18 by 9
Area = L*W
Area = 18 * 9
Area = 162 square feet
Total area = 468 + 162 = 630 square feet.
1 gallon covers 250 square feet
x gallon covers 630 square feet
1/x = 250/630
250 x = 1 * 630
x = 630 / 250
x = 2.52 gallons. It is best that she buy 3 gallons of paint.
