Answer:
80 days
Step-by-step explanation:
For each of the 5 meat choices, there are 4 vegetable choices, so a total of 5·4 = 20 meat/vegetable combinations.
For each of those, there are 4 sauce choices, so a total of ...
20·4 = 80
meat/vegetable/sauce combinations.
If a different one is ordered each day, it will take Alex 80 days before he must repeat an order.
Answer:
slope= -¾
Step-by-step explanation:
3x +4y= 9
Let's rewrite the equation into the form of y= mx +b (known as slope-intercept form), where m is the slope and b is the y-intercept.
Keep the y term on the left-hand side of the equation and move all the other terms to the right-hand side.
4y= -3x +9
For the coefficient of y to be 1, divide both sides of the equation by 4.
Answer:
The plan A lasts 1.25 hours and plan B lasts 0.5 hours.
Step-by-step explanation:
Let the plan A takes x hours for training and plan B takes y hours for training.
So, from the conditions given we can write two different equations as
4x + 8y = 9 ............ (1) and
2x + 3y = 4 ............. (2)
Now. solving equations (1) and (2) we get,
8y - 6y = 9 - 8
⇒ 2y = 1
⇒ y = 0.5 hours.
Now, from equation (2) we get,
2x = 4 - 3 × 0.5 = 2.5
⇒ x = 1.25 hours.
Therefore, plan A lasts 1.25 hours and plan B lasts 0.5 hours. (Answer)
1+1=2 2+1=3 (they are double plus 1 expressions

Steps To Solve:
15% of 24
~Turn into decimal
15% = 0.15
~Multiply
0.15 * 24 = 3.6
~Check
3.6 / 24 = 0.15 * 100 = 15%
-------------------------------------------------
Hence, 15% of 24 is 3.6!
