Answer:
3x - 4 = -19
Step-by-step explanation:
The reason is 3 times a number is equal to 3x, and then it subtracts that from 4, so it becomes -19.
Which becomes :
3x -4 = -19
There are 2 ways to turn a number into a percent...
(1) move the decimal 2 spaces to the right....0.3 = 30%
(2) multiply by 100....0.3 x 100 = 30%
a. HCF of 48 and 72 is 24
He can use 24 plates maximum.
b. 48/24 = 2
72/24 = 3
He can put 2 carrot sticks and 3 cheese puffs on each plate.
Hope this helps
