X=2. You use substitution to put the y=3x-5 into 6x+3y=15.
So you get 6x+3(3x-5)=15
=6x+9x-15=15
add 15 on both sides to get the x's alone and add the x's together.
6+9=15 -- 15+15=30
15x=30
30/15 =2
x=2
Answer:
|d - 5| ≤ ¾
Step-by-step explanation:
We are told that Jenny runs five miles a day.
Also, we are told that he has an absolute error value of ¾ mile.
Thus, it means the true distance he ran could range from between (5 + ¾) to (5 - ¾) miles.
Let the distance he runs per day be denoted as d.
Thus, absolute value equation can be written as;
|d - 5| ≤ ¾
Answer:
x = -4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Flip the equation.
Step 3: Add 1 to both sides.
Step 4: Multiply both sides by 2.
Therefore, x = -4.
<span>A proportion is two ratios that have been set equal to each other;
a proportion is an equation that can be solved.
When I say that a proportion is two ratios that are equal to each other, I mean this in the sense of two fractions being equal to each other.
For instance, 5/10 equals 1/2.</span>
