Answer:
PArt 1: 4/40 (not simplified) 1/10 (simplified)
Part 2: 8/40 (not simplified) 2/10 (simplified)
Step-by-step explanation:
add all the marbles together and you get 40. there are 4 colors in the jar but with different amounts, you will divide 40 into each amount of marbles (example: 40/4 = 10 = there are 4 10s in 40).

Answer:
12/(7-4) + 5 * 3 = 19
Step-by-step explanation:
Given
Untrue Expression: 12 ( 7 − 4 ) + 5 3 = 19
Signs: +−×÷
Required
Use the given signs to make the equation true.
To solve this, the trial and error method will be adopted.
The trial and error method involves trying series of sign combinations in the given expression; whichever works is the right answer.
So, after few attempts the following makes the equation true
12/(7-4) + 5 * 3 = 19
To check if it's true or not; we simply expand the expression on the left hand side. This gives
12/3 + 5 * 3 = 19
4 + 5 * 3 = 19
4 + 15 = 19
19 = 19.
Hence, the sign combinations used in 12/(7-4) + 5 * 3 = 19 is correct.
Answer:
2, 6, 12, 20, 30
Step-by-step explanation:
To find the first 5 terms substitute n = 1, 2, 3, 4, 5 into the expression
n = 1 → 1² + 1 = 1 + 1 = 2
n = 2 → 2² + 2 = 4 + 2 = 6
n = 3 → 3² + 3 = 9 + 3 = 12
n = 4 → 4² + 4 = 16 + 4 = 20
n = 5 → 5² + 5 = 25 + 5 = 30
