Let x+y=10 be equation (1)
and y=x-4 be equation (2)
from (2)
y=x-4...(3)
sub (3) into (1)
x+(x-4)=10
x+x-4=10
2x=12
x=6
sub (x) into (3)
y=6-4
y=2
Answer:
n = 19/18
Step-by-step explanation:
11/6 = n + 7/9
To isolate n, we want to subtract 7/9 from both sides.
11/6 - 7/9 = n
To subtract these fractions, they need to have the same denominator. A common multiple of 6 and 9 is 18.
11/6 ⇒ 33/18
7/9 ⇒ 14/18
33/18 - 14/18 = 19/18
n = 19/18
Hope this helps!
List all the info:
3/8 gallon of white paint
2 7/8 gallon of blue paint
11/4 gallon of red paint
First, let’s answer the first question.
Francis has made _____ gal of paint when he first mixes the three colors.
Add all the gallons of paints together and you get 6. So, Francis has made 6 gal of paint when he first mixes the three colors.
Now for the second blank. All you have to do is do 6 divided by 3/8 which is 16. So, The constant of proportionality of white paint to gallons of mixed paint is 16.
Lastly, you will have to do is 3/8 x 7 = 2 5/8. (Im not too sure about this part though, but the rest I‘m pretty confident about)
