Answer:
It's the last one where x=3 and y=2
Explanation:
Replace x and y with 3 and 2. It then becomes
-4(3) + 8(2) = 4
Solve. -4 × 3 is -12 since a positive times a negative equals a negative. 8 × 2 is 16. Bring down the 4.
-12 + 16 = 4
When solving something like this and you don't know what to do or how to solve it, you can subtract the smaller number from the larger number and then whether the sum is a negative or positive depends on the largest number. So here, 16 is the largest, so the sum will be positive. And 16-12 is 4, so the final answer is positive 4. You can also look at a number line and start from -12 and then add 16 and see which number you end at after adding 16.
If you divide 1060 by 1325
1060/1325=80%
The volume of the cuboid is 132 cubic inches.
Given length of cuboid 7 1/3 inches, breadth being 6 2/3 inches , height being 2 7/10 inches.
Volume is amount of liquid a container can hold in its capacity. Cuboid is a 3 dimensional figure having length , breadth and height.Volume of cuboid is the product of length, breadth and height of cuboid.
We have to calculate volume of cuboid.
We have to make a simple fraction showing length , breadth and height.
Length=(3*7+1)/3=22/3
Breadth=(3*6+2)/3=20/3
Height=(10*2+7)/10=27/10
Volume=22/3*20/3*27/10
=11880/90
=132 cubic inches.
Hence the volume of cuboid having length of 22/3 inches, breadth of 20/3 inches and height of 27/10 is 132 cubic inches.

Question is incomplete as it should include figure.
Answer:
The year is 1979.
Step-by-step explanation:
Given:
The function relating fish population and number of years since 1972 is:
Now, when the fish population reaches 99 thousand, it means that . Now, plugging in in the above equation and solving for . This gives,
Therefore, the year after 7 years passed since 1972 is given as:
1972 + 7 = 1979.
So, the year when the number of fish reaches 99 thousand is 1979.
