The answer is x=6 and y=4.
6+4=10
and 8 times 6 + 12 times 4 is 96.
Answer:6x+36, 5x+5, 10x-9
Step-by-step explanation:
Answer: 12 friends.
Step-by-step explanation:
the data we have is:
Mei Su had 80 coins.
She gave the coins to her friends, in such a way that every friend got a different number of coins, then we have that:
The maximum number of friends that could have coins is when:
friend 1 got 1 coin
friend 2 got 2 coins
friend 3 got 3 coins
friend N got N coins
in such a way that:
(1 + 2 + 3 + ... + N) ≥ 79
I use 79 because "she gave most of the coins", not all.
We want to find the maximum possible N.
Then let's calculate:
1 + 2 + 3 + 4 + 5 = 15
15 + 6 + 7 + 8 + 9 + 10 = 55
now we are close, lets add by one number:
55 + 11 = 66
66 + 12 = 78
now, we can not add more because we will have a number larger than 80.
Then we have N = 12
This means that the maximum number of friends is 12.
Answer:
To convert from degree to radian we multiply the angle by
π/180
To convert from radian to degree we multiply the angle by
180/π
5π/6,
Multiply by
180/π
=
5π/6 × 180/π = 5 × 30 = 150 degrees.
⇒5π/6 radian =150 degree.
Answer:
B
Step-by-step explanation:
Given
6p³ - 12p² + 9p ← factor out 3p from each term
= 3p(2p² - 4p + 3) → B
