Write an algebraic expression with two terms to represent the total of balloons sold my all 3. in terms C last year three 6th grade students alia crystal and shamika were selling balloons at the school winter dance to collect 360$ for a class trip to a zoo

30/c

Step-by-step explanation:

Evaluate 7a+b/b+c, if a=2, b=6, and c=4.Find the solution of 3(y+7)is less than or equal to 39 if the replacement set is {2,4,6,8,10.12}. The equation 4+9=4+9 is an example of which property of equality?

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
