Sample Equation: 3x - 3 = 27
Multiple step:
3x - 3 = 27
<u> + 3 +3</u> Step1. Remove the -3 by adding 3 to both sides
3x = 30
<u>÷3 ÷ 3</u> Step2. Remove the multiplicand 3 by dividing both sides by 3
x = 10
To check: substitute x by its value
3x - 3 = 27
3(10) - 3 = 27
30 - 3 = 27
27 = 27
Answer:
92 pounds
Step-by-step explanation:
Here is the complete question ;
4 people are going to a dinner party. Each person at the party will eat 23 pound of cake. If you can only buy whole pounds of cake, how many pounds should you buy?
total pounds to be bought = number of people at the party x total pounds they would eat
4 x 23 = 92 pounds
The slope of the line as shown in the graph attached is 7/3
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be independent or dependent. A dependent variable depends on other variable while an independent variable does not depend on other variable.
A linear equation is in the form:
y = mx + b
Where m is the rate of change (slope) and b is the y intercept.
The slope of a line = vertical rise / horizontal run
From the image:
Slope = rise / run = 7/3
