25.00 < (with a line under it) 4.50+2.50x
Step-by-step explanation:
Answer:
1. 24,000,000, i believe you divide, 300,000/80.
2. 4.065 seconds, i also believe you divide 5000m/1230.
1 (B), because 3+-2=1, and 5+-4=1, which amounts to 1/1, or whole number 1.
Answer:
336
Step-by-step explanation:
area = 1/2 * (a + b) * h
STEP 1:
determine equations needed
x= # of $10 tickets
y= # of $14 tickets
QUANTITY EQUATION
x + y= 800
COST EQUATION
$10x + $14y= $9,040
STEP 2:
multiply quantity equation by -14
-14(x + y)= -14(800)
-14x - 14y= -11,200
STEP 3:
add new quantity equation in step 2 to cost equation of step 1 to solve for x using elimination
-14x - 14y= -11,200
10x + 14y= 9040
y term cancels out
-4x= -2160
divide both sides by -4
x= 540 ten dollar tickets
STEP 4:
substitute x value in step 3 into either original equation
x + y= 800
540 + y= 800
subtract 540 from both sides
y= 260 fourteen dollar tickets
ANSWER: There were 540 $10 tickets and 260 $14 tickets sold.
Hope this helps! :)
