-5(y-15=3x) = -5y+75=-15x
add 15x to both sides and subtract 75 to both sides
-5y+15x=-75
5y-2x=-3
13x=-78
divide 13 to both sides
x=-6
y-15=3(-6)
y-15=-18
add 15 to both sides
y=-3
so the answer is (-6,-3)
I hope that this helped you sweetie :)
Answer:
2/7
Step-by-step explanation:
To find the this first you need the total number of marbles minus one since the blue marble was taken.
4+5+6-1=14
after one blue marble being picked there are 4 blue left, so the fraction is
4/14 and after being simplified it is 2/7
If we want to simplify Algebraic Fractions:
We have to take a look at the numerator and the denominator
Why? Because to simplify we need to have a common multiple.
When we find the common multiple, we now know by which factor we have to break down the fraction in the numerator and the denominator
I have some examples attached below for help.
Answer:
x=(10-k)÷6
Step-by-step explanation:
6x=10-k
x=(10-k)÷6
Answer:
Green and Blue ribbon
Step-by-step explanation:
Given
They collect
Red Ribbon = ½ mile
Green Ribbon = ⅛ mile
Blue Ribbon = ¼ mile
To find?
Which colors of ribbons will be collected at the ¾ mile mark.
The interpretation of the question is to test which of the above fractions can divide ¾ without a remainder; in other words, multiples of ¾.
Testing each fraction.
Red Ribbon = ½
¾ ÷ ½
= ¾ * 2
= 3/2
= 1.5 or 1 Remainder 1
This is not an exact multiple of ¾. So, the red ribbon won't be passed here.
Green Ribbon = ⅛
¾ ÷ ⅛
= ¾ * 8
= 24/8
= 3
This is an exact multiple of ¾. So, the green ribbon will be collected.
Testing the last ribbon
Blue = ¼
¾ ÷ ¼
= ¾ * 4
= 3
This is an exact multiple of ¾. So, the blue ribbon will be collected.
Hence, the green and blue ribbons will be collected at ¾ mile mark
