Plug 4x=9 in for y:
10x=18-2(4x+9)
10x=18-8x-18
10x=-8x
18x=0
x=0
now plug 0 in for x:
y=4(0)+9
y=9
to check, plug x and y back into one of the equations to make sure they are right:
10(0)=18-2(9)
0=18-2*9
0=18-18
0=0
Answer: 80 cents per organic peach
Step-by-step explanation: To find out how much Patrick paid for 5 organic peaches, we want to find the unit price for 1 peach.
Unit price means the cost per unit. In this case, the cost per peach. Since we know that it costs $4.00 for 5 peaches, to find the cost for 1 peach, we need to divide 5 into $4.00 or 5 into 4.00.
Now using long division, 5 divides into 40 eight times so we put an 8 above the second 0 and 8 x 5 is 40 and 40 - 40 is 0.
So 5 divides into 4.00 0.8 times which means that each peach costs 80 cents.
So the unit price is 80 cents per organic peach.
Hey!
To find volume, you have to multiply the length, width, and height. All you have to do is multiply the 3 numbers together.
