Answer:
you need to simplify it then you can say that he had marbles and then lost __ then got ___
Answer:
y=1.6x+7.2
Step-by-step explanation:
First you want to find m or the slope so use the formula m=y2-y1/x2-x1 and you get your slope which is 1.6.
Then you plug in your slope to the equation including another coordinate or example (3,12) plugged in to make 12=1.6(3)+b. Now you can solve for b.
Once you do that you get b=7.2
So now with m=1.6 and b=7.2, you can finally make the equation.
y=1.6x+7.2
To solve the equation, subtract 3 from both sides. The solution is k = 11.
A linear equation is an equation of which the highest degree of its variables is 1.
Steps to solve linear equations:
- Simplify the expressions. If there are parentheses, remove them by multiplying the corresponding terms.
- Combine the same terms.
- Isolate the variable on one side by using subtraction of addition.
- Use division or multiplication to find the value of the variable.
Recall that if we subtract or add the same number to both sides of an equation, it does not change the equality.
The given problem:
Solve k + 3 = 14.
The variable is k. Subtract 3 from both sides:
k + 3 - 3 = 14 - 3
k = 11 (solved)
