Answer:

Simplifying
12b + -1b = 77

Combine like terms: 12b + -1b = 11b
11b = 77

Solving
11b = 77

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Divide each side by '11'.
b = 7

Simplifying
b = 7

Jordon missed 49 on his multiple choice math final and earned a grade of 65%. How many total questions were on the final exam?

Then, you would guess and check try 49/60, 49/70, and go up by 10s or 5s. You will then realize that 49÷75 equals 65.333. This rounds up to 65.

1/3t + 3/4 = 2/4 -t solve
olga55 [171]
Okay so I am going to summarize the work out process because its a lot to

Here we go

1/3 (t) + 3/4 - 2/4 - t = ?

1/2 (simplify )

(1/3 (T)+3/4 - 1/2 - (t) = ?

t (2) / 2

1 - 2(t) / 2 = ?

3/4 (simplify this )

1/3(t)+ 3/4 - [1 - 2(t) / 2 = ?

1/3 (this is re last one you have to simplify)

L (Denominator): 3

R (Denominator): 4

L: [L.C.M] : 4

R: [L.C.M] : 3

Basically , we just switched the dominators around

So, Therefore The of t is -3/16


T = -3/16
