Dan was trying to get faster at his multiplication tables. this table shows the time it took him to complete each of four tests containing 50 simple multiplication problems.

which comparison of the time for each test is correct?
test 1 < test 4
test 2 > test 4
test 1 > test 3
test 3 < test 2

Test 1 < Test 4

Step-by-step explanation: Test 1 was easier so it took less time to complete the questions. As the tests continue they get harder meaning they will take more time to answer.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

yes. we do proportions in probabilities.
