Answer:

See below

Step-by-step explanation:

70/100 + 4/10 is equivalent to 70/100 + 40/100 which equals 110/100.

68/100 + 6/10 is equivalent to 68/100 + 60/100 which equals 128/100.

6/10 + 12/100 is equivalent to 60/100 + 12/100 which equals 72/100.

4/10 + 34/100 is equivalent to 40/100 + 34/100 which equals 74/100.

None of them equal 75/100, however if you were looking for 74/100 or 72/100, check above.

How do you solve -14+6b+7-2b=1+5b

Ronch [10]

Step 1: Rewrite the equation

-14+6b+7-2B=1+5b

Step 2: Combine like terms

-14+6b+7-2b=1+5b

-7+4b=1+5b

Step 3: To isolate b, first add 7 on both sides

-7+4b=1+5b
+7 +7
_________
4b=8+5b

Step 4: Again, trying to isolate b, subtract 5b on both sides

4b=8+5b
-5b -5b
_______
-b=8

Step 5 (final step): Because the variable cannot be negative for a final answer, multiply each number by -1.

-1(-b=8)

b= -8

Final Answer: b=-8

Hope this helps :)

Answer:

2.75 seconds.

Step-by-step explanation:

We have been given that a ball is dropped from the ground. T represents the time in seconds.

To find the time when the ball was in air, we will equate height of ball with 0 and solve for t.

$-16t^2+44t=0$
