A.) - 1/5
Step-by-step explanation:
I divided each side by factors that do not contain the variable.
Answer:
(3,4)
Step-by-step explanation:
x+y=7, where y=4, so therefore make x the subject and substitute y=4
x=7-y
x=7-4
x=3
therefore x=3, y=4.
Well 12 times four is 48 so you add 48 and 1 and the first fraction (12 1/4) becomes 49/4 then you multiply this by two so it becomes 98/8 now you can take 98 dived by 7 to make 14 speed limit signs on the highway
6/15 + 10/15 = 16/15 = 1 1/15
6/15 - 10/15 = -4/15
Green paint is made by mixing yellow and blue paint. Given that, every 4 gallons of green paint contains 3 gallons of blue paint, how many gallons of yellow paint is in 4 gallons of green paint? Green-blue=yellow
4-3=1 Therefore 1 gallon of yellow paint is in 4 gallons of paint.
The ratio of blue to yellow is 3:1
If there are 16 gallons of green paint, how many gallons blue and yellow are in it? blue= 3 in 4 green
If 16=4
=3
3/4*16=12 Therefore there are 12 gallons of blue paint in 16 gallons of green paint.
Yellow=1 in 4 gallons
If16=4
=1
1/4*16=4 Therefore there are 4 gallons of yellow paint in 16 gallons of green paint.
