The answer is A because 2time 2 is 4-2 =2 and then 120times 2 =240
Answer: 5 days
Step-by-step explanation:
Let the number of pallets that the tan gerbil eat be x.
Since the brown gerbil eats 10 less than 4 times the number of pallets as the tan gerbil and eats 30 pallets pee day. This will be:
(4 × x) - 10 = 30
4x - 10 = 30
4x = 30 + 10.
4x = 40
x = 40/4
x = 10
The tan gerbil eats 10 pallets per day.
Both gerbil eats (30 + 10) = 40 gerbils per day.
Since the family has 200 pallets of food left, the number of days that they can feed both of the gerbils would be:
= 200 / 40
= 5 days
Answer:
Step-by-step explanation:
<u>Exponent properties</u>:
We can use exponent property to solve this problem.
Rewrite as , then apply exponent property to simplify:
If , then , because of log property . Using this log property, you can take the log of both sides and divide by to get
Therefore, we have:
Subtract 3 from both sides:
Divide both sides by 6:
<u />
<u>Alternative</u>:
Given , to move the exponent down, we'll use log properties.
Start by simplifying:
Take the log of both sides, then use log property to move the exponent down:
Divide both sides by :
Subtract 3 from both sides:
Divide both sides by 2:
Subtract the width of the towel bar from the width of the door and divide by 2.
70 1/3
- 24 1/4
--------------
You need a common denominator to subtract the fractions. The LCD is 12,so we can rewrite the subtraction using the LCD.
70 4/12
- 24 3/12
--------------
46 1/12
Now you need to divide 46 1/12 by 2.
46/2 = 23
(1/12) / 2 = 1/24
The answer is 23 1/24 cm
13x+15y=55.50 and 46x+16y=131.50 is the system that could be used to determine the price of each pound of bananas and the price of each pound of grapes where x is the price of each pound of bananas and y is the price of each pound of grapes.
Step-by-step explanation:
Let,
x represent the price of each pound of bananas
y represent the price of each pound of grapes.
According to given statement;
13x+15y=55.50
46x+16y=131.50
13x+15y=55.50 and 46x+16y=131.50 is the system that could be used to determine the price of each pound of bananas and the price of each pound of grapes where x is the price of each pound of bananas and y is the price of each pound of grapes.
