Answer:
x = 2 × 3 11/6 ≅ 2 × 7.5 ≅ 15
Explanation:
6 log₃ (0.5x) = 11
log₃ (0.5x) = 11/6
Here we make both sides the exponent of a base 3. It'll be the inverse function for the left hand side and cancel out the log.
3ˡᵒᵍ₃ ⁽ ⁰.⁵ˣ ⁾ = 3 11/6
0.5x = 3 11/6

<em>Hence the answer:</em>
<em></em>
x = 2 × 3 11/6 ≅ 2 × 7.5 ≅ 15
Answer:
112 stickers
Step-by-step explanation:
Let x and y represent the number of stickers Sheryl and Jennifer were given at first.
Sheryl and Jennifer were given the same number of sticker at first.
So;
x = y ......1
After jennifer used 84 stickers ,sherly had 4 times as many stickers as jennifer.
x = 4(y-84)
x = 4y - 336 ......2
Substituting equation 1 into 2
y = 4y - 336
Solving for y;
4y - y = 336
3y = 336
y = 336/3
y = 112
Therefore, sherly was given 112 stickers at first
Answer:
y = -3
Step-by-step explanation:
9x + 7y = -12
9(1) + 7y = -12
9 + 7y = -12
7y = -12 - 9
7y = -21 (divide both sides by 7)
y = -3
Jeromes flight was 2hrs20mins
Rachael's flight was 2hrs 35mins
So overall Rachael's flight was longest but 15 mins
