Answer: A! x=-1 2/5, y= 1 3/5
Step-by-step explanation:
First put -3x+3y=9 into slope-intercept form(y=mx+b)
3y=-3x+9
then solve for y
y=-1x+3
enter your y-intercept into the equation below..
2x-7(-1x+3)=-14
2x+7x-21=-14
2x+7x=-14+21(when changing sides it changes signs that's why 21 is now a positive)
2x-7x=7
-5x=7 divide -5 into 7
7/5
x=-1 and 2/5
then input x back into the first equation
-3(7/-5)+3y=9
21/5+3y=9
3y=9-21/5
3y=24/5
divide 3 into 24/5
=24/15=1 and 9/15 reduce it anddd
y=1 and 3/5
Step-by-step explanation:
Work out 32 as a product of prime factors in index form
First find out the factor for 32
32 can be break into 16 times 2
16 can be break into 8 times 2
8 can be break into 4 times 2
4 can be break into 2 times 2
So, 32 can be written as
Answer:
The index form of the 32 is
Answer:
Step-by-step explanation:
4/3 ÷ 2 = 2/3.
2/3 water waters 1/5 plants in the house.
2/3 x 5 = 10/3.
1/5 x 5 = 1.
10/3 = 3 1/3.
3 1/3 liters of water are needed to water all the plants in the house.
