Answer:
3 lbs
Step-by-step explanation:
7 lbs total
2 + 2 = 4 so we already have 4lbs
7 - 4 = 3
we need 3 more lbs
Answer:
Cost of one candy = 80 L.L.
Step-by-step explanation:
Let "x" represent cost of a candy
Cost of 12 candies = 12x
Cost of a chocolate bar = 1,250 L.L.
Total cost = 2,210 L.L.
The following equation represents the scenario given:
1,250 + 12x = 2,210
Solve for x (cost of a candy)
1,250 + 12x - 1,250 = 2,210 - 1,250 (subtraction property of equality)
12x = 960
Divide both sides by 12
12x/12 = 960/12 (division property of equality)
x = 80
Cost of one candy = x = 80 L.L.
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.
