Step-by-step explanation:
Okay this is an odd question, but what i'm thinking is that
first you have
5x+5
To actually be able to solve we have to move the 5 to the other side.
To do this we subtract it.
Making the equation
5x = -5
Then you need to isolate the variable (X)
So divide 5X by 5, and then divide -5/5
Which leaves you with:
x=-1
Answer: 7/10
Step-by-step explanation:
First you add the total number of marbles. Then, you take the total number of blue marbles, and make that your denominator. The total number of marbles is your numerator.
Answer:
y = (-8/9)x + 0.77777
Step-by-step explanation:
We already know the slope, so the only thing left to find is the y-intercept.
To find the y-intercept, we can <u>plug in the slope and point to the slope-intercept form equation</u> (y = mx+b, where m=slope and b=y-int.)
y = m * x + b
(7) = (-8/9)*(-7) + b
<u>Now, just solve for b!</u>
(7) = (-8/9)*(-7) + b
7 = 56/9 + b
7 - (56/9) = b
b = 0.777777 (repeating decimal, usually signified by a little line above the 7)
so now we just <u>plug in the slope and y-intercept we found into y = mx + b.</u>
y = mx + b
y = (-8/9)x + 0.77777
