Answer:
r = - 189
Step-by-step explanation:
Given
- 13 = 
+ 8 ( subtract 8 from both sides )
- 21 = ( multiply both sides by 9 )
- 189 = r
Answer:
ans : general term = (2n +8)/(4^n) * (-1)^n
f(-2) means replace x in the equation with -2, then solve:
-2^2 +5(-2)
Simplify:
4 + -10
Add:
-6
Answer:
6 bowls of ramen eaten by you & your friend
Step-by-step explanation:
The question appears pretty choppy for me. I'll answer what I think you're asking and update in the comments if needed.
Imagine that you and a friend go to a local ramen shop for dinner at this restaurant, each regular bowl of ramen is $7.25. Drinks are $1.50 each. How many regular bowls of ramen did you and your friend eat if you ordered 2 drinks each and your total was $49.50?
a. Write an equation to represent the situation using x to represent the # of bowls you and your friend ate.
4($1.50) + $7.25x = $49.50
6 + 7.25x = 49.50
subtract 6 from both sides
7.25x = 43.50
divide both sides by 7.25
x = 6
Checking the math:
4(1.5) + 6(7.25) = 6 + 43.50 = 49.50
4 drinks, 6 bowls of ramen for $49.50
Answer:
9/40
Step-by-step explanation:
To find the price per can, we take the cost and divide by the number of cans
$5.40/24
5.4/24
Since there is a decimal in the numerator, multiply the top and bottom by 10
5.4/24 * 10/10
54/240
Divide the top and bottom by 6
9/40
