Answer:
6x - 1
Step-by-step explanation:
Okay this is basically polynomial algebra:
1. Add the value of the lengths already given.
like terms: 3x + x = 4x, -4 + 2 = -2. Now you're left with, 4x - 2.
2. Find the difference between the perimeter and the sum of the lengths.
(10x -3) + (4x + 2) = 6x - 1
To find this you would divide 868cupcakes by 31boxes witches is 28cupcakes in each box
hope this helps good luck have a good nite hope u enjoy ur the rest of ur weekend
Answer: 6 years old.
Step-by-step explanation:
For this exercise let "x" represents your present age.
According to the information provided in the exercise, you know that In three years, Chad will be three times your present age.
Then, your age in three years can be represented with the following expression:

Knowing at that time Chad's age will be three times yours and you will be half as old as old as Chad, you can write the following equation to represent this situation:

Therefore, the final step is to solve for "x" in order to find its value.
You get that this is:

3 and -3
They are both the same distance from zero (definition of absolution value)
Answer:

Step-by-step explanation:
To find the slope, all we need is to points on the line.
Judging by that graph, we can see a point at (0,1) and at (5,4).
Simply enter this into the slope formula and you'll have your slope.

Your y1 term is 1, your y2 term is 4.
Your x1 term is 0, your x2 term is 5.

Your slope is
