Jill bought oranges and bananas. she bought 12 pieces of fruit and spent $5. oranges cost $0.50 each and bananas $0.25. write a system of equations to model the problem. then solve the system algebraically. how many oranges and how many bananas did Jill buy? *show work please*

Answers

x=number of oranges.
y=number of bananas.
$5

we can suggest this system of equations:
x+y=12
0.5x+0.25y=5
We can solve this system of equations by substitution method.
x=12-y

0.5(12-y)+0.25y=5
6-0.5y+0.25y=5
-0.25y=5-6
-0.25y=-1
y=-1 /- 0.25=4

x=12-y
x=12-4=8

Answer: Jill bought 8 oranges and 4 bananas.

Mr. Barber uses 7/9 yard of wire to put up a ceiling fan. He uses 1/3 yard of wire to fix a switch How much more wire does he use to put up the fan than to fix the switch

Answers

1/3 is the same as 3/9. To solve this, subtract 3/9 from 7/9.

(7)/(9)-(3)/(9)= (4)/(9)

Your answer is (4)/(9)

What is the answer to this?
The variable is what we are finding
−​5/19​​x>−3

Answers

it could be 2 things
(-5/19)x>-3 or
-5/(19x)>-3
if it is the first one, go to AAAAAA
if it is second one go to BBBBBBB


(-5/19)x>-3
multiply both sides by -19/5 to clera fraction (-5/19 times -19/5=-95/-95=1)
x>-57/5
x>-11 and 2/5


BBBBBBBBB
-5/(-19x)>-3
multiplyboth sides by -19x
-5>57x
divide both sides by 57
-5/57>x


if it is (-5)/(19)x>-3 then  x>-57/5
if it is (-5)/(19x)>-3 then x<-5/57
