Answer:
The answer is 40a+14c
Step-by-step explanation:
Step 1: Open the brackets
7a-9c+12a+33c+21a-10c
Step 2: Group all the like terms
Like terms are terms with similar variables, for example;
(7a, 12a, 21a) are all like terms since they have a common variable (a)
(-9c, 33c,-10c) are also like terms since they have a common variable (c)
Step 2: Solve
(7a+12a+21a)+(33c-10c-9c)=40a+14c
The answer is 40a+14c
Answer:
C) 60 degrees
Step-by-step explanation:
An equilateral triangle has all equal angles. We know that all the angles of a triangle add up to 180 degrees. Therefore 45+45+45=180 giving you an equilateral triangle angle measure.
A. Let x represent the number of miles and y represent the total price.
y=3x+15
B. Using the equation we just wrote, replace the x with 45.
y=3(45)+15
Now multiply 45 by 3.
y=135+15
And finally add together 135 and 15.
y=150
The total cost of a 45 mile taxi ride would be $150.00.
Answer:
When an equation is in standard form, the y-intercept could be given by C/B.
Step-by-step explanation:
In order to find the equation, we start with the base equation of standard for and then solve for slope intercept form.
Ax + By = C
By = Ax + C
y = A/Bx + C/B
And this shows us that C/B is the y-intercept
