-20 * 3 / -30 / 3
First multiply the top and divide the bottom to simplify the problem:
-20 * 3 = -60
-30/3 = -10
Now you have -60 / -10
Divide:
-60 / -10 = 6
Here you go. I hope this will help
Answer:
6,410
Step-by-step explanation:
2160 inches into 12 pieces.
12 pieces = 2160 inches.
1 piece = 2160 / 12 = 180 inches.
But 12 inches = 1 foot, 3 feet = 1yard
3*12 = 36 inches = 1yard.
36 inches = 1yard.
180 inches = 180/36 = 5 yards.
Each piece was 5 yards long.
Answer:
6days
Step-by-step explanation
Let's make an equation from this expression.
From the number of potatoes at the first warehouse after x days is:
y = 210 + 90x .............. 1
From the number of potatoes at the second warehouse after x days is:
y = 180 + 120x .............. 2
First warehouse having 1.2times
y = ( 210 + 90x ) × 1.2
y = 252 +108x ................... 3
Now, equate 2 and 3
252 + 108x = 180 + 120x
252 - 180 = 120x - 108x
72 = 12x
x = 72/12
x = 6
Now, substitute 6 into equation 1 and 2
From 1 , y = 210 + 90x
y = 210 + 90 ×6
y = 210 + 540
y = 750
From equation 2
y = 180 + 120x
y = 180 + 120×6
y = 180 + 720
y = 900
Recall that equation 1 was to be 1.2times
From the answer in equation 1
y =750
y = 750 × 1.2
y = 900
Hence, the answer is correct.
