Li keeps track of the time he spends working out each week. The table shows the
number of cardio workouts and the number of weighted workouts for 3 recent weeks,
The total time in minutes for weeks 1 and 2 are given. Each cardio workout is the same
length of time, and each weighted workout is the same length of time. The system of
equations can be used to represent this situation.
Use the drop-down menus to complete each statement.

The total time Li spent for week 3 was 210 minutes.

Step-by-step explanation:

Step 1; Assume x to be the number of cardio workouts a week and y be the number of weighted workouts a week, so we have

4x + y = 210, take this as equation 1 ,

3x + 2y = 195, take this as equation 2 .

Step 2; We multiply equation 1 with 2 and equation 2 with 1 so we can cancel out the variable x in both equations. By doing this we get

8x + 2y = 420, take this as equation 3,

-18x +4y =32, this is equation 2

If we subtract equation 2 from equation 3, we cancel out the y variable and can calculate the value of x.

5x = 225 , x = 225/5 = 45, x = 45.

Step 3; Substituting this value of x in any of the previous equations we will get x's value. Here this value of x is substituted in equation 1.

4(45) + y = 210, 180 + y = 210 , y = 210 - 180, y = 30.

So we have x = 45 and y = 30.

Step 4; Now we calculate the time spent in the third week by substituting the values of x and y in 2x + 4y,

2x + 4y = 2 (45) + 4 (30) = 90 + 120 = 210 minutes.

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84

step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
