Answer:
133/3= 147/5 =
44 29.7
44-29.7
14 pies can be made.
133/4 147/2
33.25 73.5
73.5-33.25
40 jars of apple sauce can be made
(I rounded my decimals)
Step-by-step explanation:
You need to invert each operation so first start by subtracting 320 from each side that leaves 2x=120 then divide each side by 2 to get x by itself leaving the answer as x=60
Answer:
(-2,8)
Step-by-step explanation:
-7x-2y = -2
-6x+8y = 76
Multiply the first equation by 4 to eliminate y
-28x -8y = -8
Then add it to the second equation
-28x -8y = -8
-6x+8y = 76
--------------------
-34x = 68
Divide by -34
-34x/-34 = 68/-34
x = -2
Now substitute back into one of the equations to find y
-6x +8y = 76
-6(-2) +8y = 76
12+8y = 76
Subtract 12 from each side
12+8y-12 = 76-12
8y = 64
Divide each side by 8
8y/8 = 64/6
y=8
(-2,8)
Answer: 12 child tickets
Step-by-step explanation:
We can use system of equations to find how many child tickets were sold. Let's say x is adult and y is child.
Equation 1
5.25x+3.05y=498.6
This equation comes from the cost of tickets.
Equation 2
x+y=100
This equation comes from the number of tickets.
We can use elimination method to solve for y.
5.25x+3.05y=498.6
5.25x+5.25y=525
Now, we can subtract the equations for x to cancel out and to solve for y.
-2.2y=-26.4
y=12
122/(11*6) = 122/66 = 61/33 = 61 rose bushes per 33 meters squared
