Answer:
87+87+81+86+89+83+89= 602. Divided by 7 because that’s how many numbers there were is 86 and that is your mean/average.
This is Bridge Algebra 2 stuff. Well you see that 2x+y=8 and x-1=y. To slove for y you have to slove for x first to find y. So 2x+x-1=8 ( the reason I did that is because there is a y in that equation and I placed it on that equation) now lets slove this equation for x. So 3x-1=8( I add 2x with x) 3x=9 ( I made -1 a positive one and add it to 8) x=3 ( I divided 9/3 to get 3). Now that you have slove x we will use x to slove for y. So 3-1=y, 2=y. Your answer is y=2.
The answer is (3,2)
To get this answer we either...
A) Multiply both coordinates by 1/3
or
B) Divide each coordinate by 3
9*(1/3) = 9/3 = 3
6*(1/3) = 6/3 = 2
Answer:
Step-by-step explanation:
Tax
Meal plus tax = 25.3 + 8/100 * 25.3
Meal plus tax = 25.3 + 2.024 Round later. Find the total.
Meal plus tax = 27.324
Meal plus tax = 27.32 rounded to the nearest cent.
Tip
Total cost = 27.324 + 27.324 * 18 /100
Total cost = 4.91832 + 27.324
Total cost = 32.242
Rounded to nearest cent = 32.24 You should always round at the last step.
Answer:
The answer is "y < 2x - 4".
Step-by-step explanation:
Write in <u>slope-intercept</u> form, the formula is "y = mx + b"
