Adam wants to mix 10 cups of fertilizer from concentrate. He needs to mix one part of fertilizer concentrate with 4 parts of water. He wrote the system of equations to represent the amount fertilizer concentrate and water needed and then graphed the first line. y = one-fourth x. x + y = 10. A graph titled Fertilizer from Concentrate has cups of water needed on the x-axis and cups of concentrate needs on the y-axis. A line goes through (0, 0) and (4, 1). Graph the second line. What is the solution to the system? (0, 2.5) (4, 6) (5, 5) (8, 2)

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

answer:

a=9

step-by-step explanation: lmk if you need a explanation

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
