-18 because 9 times 2 is 18 but because you're multiplying a negative with a positive it equals -18

The volume of a large aquarium is 210 yd. It is 3 yd wide and 2
Pavel [41]

Length of the aquarium is 35 yd

Step-by-step explanation:

  • Step 1: Volume of the aquarium = 210 yd³ given by Volume = length × width × height. Width = 3 yd and Height = 2 yd

Length = Volume/Width × Height

            = 210/3 × 2 = 210/6

            = 35 yd

Solve the system of equations by elimination. Show your work. i’ll give brainliest
My name is Ann [436]

Answer:

x = 5

y = 4

Step-by-step explanation:

multiply the second equation by -1 and add the first equation to eliminate "x"

4x+6y=44\\-4x-2y=-28
_____________

       4y=16

y=16/4 =4

Replace "y" in the first equation:

4x+6(4)=44

4x+24=44

4x=44-24

x=20/4=5

Hope this helps

Can someone help me?
bixtya [17]

Answer:

y = 2.1x +5, 21 miles

Step-by-step explanation:

We will denote miles as "x"

Since she tipped the driver $5, that is a flat rate and that will be our y-intercept. Since it costs $2.10 per mile, we need to multiply that number by the number of miles

So our equation will be y = 2.1x +5

In order to figure out how many miles Ann lives from the airport, we need to substitute y for her grand total that she was charged

This gives us 49.10 = 2.10x + 5

First we need to subtract 5 from each side to get 44.10 = 2.10x

We then need to divide both sides by 2.10 to get 21 = x

Ann drove 21 miles
