Let L represent the number of ribbons Lily has and D be the amount of ribbons Dora has.
Since Lily has 4 fewer ribbons than Dora, the amount of ribbons Lily has can be represented as this:
L = D - 4
Because Lily has 7 ribbons, you can plug in 7 for L:
7 = D - 4
When you solve for the amount of ribbons Dora has (D), which is done by adding 4 to both sides, you get D = 11.
Therefore, Dora has 11 ribbons.
Answer:
C. 74
Step-by-step explanation:
add up all the numbers but not the value so you have 18 numbers. divide that by 2 and get 9. so 74 is between 73 and 78 so it divides the 18 numbers evenly into 9 and 9.
Answer:
x³ - 2x² + 2x - 2
Step-by-step explanation:
f(x) - g(x)
= 2x³ - 4x² + 2 - (x³ - 2x² - 2x + 4) ← distribute by - 1
= 2x³ - 4x² + 2 - x³ + 2x² + 2x - 4 ← collect like terms
= x³ - 2x² + 2x - 2
Answer: x=4000.
