Answer:

95

Step-by-step explanation:

Being a sum of two elements that include units and tens, we can make the sums of the units first, and then add the tens together.

So, if we have 45+50, we can first separate the units:  5 + 0 =5

Then, we separate the tens: 4+5=9

Now, we only join the sums of the units and tens, and that will be the end result.   95

Andre45 [30]

Answer:

D, (1,2)

Step-by-step explanation:

It all comes down to substitution. In this case the coefficient of x is 3 and the coefficient of y is 4. The format of these coordinates being (x,y).

1. Plug in your x value (1 in this circumstance) and solve:

3(1) + 4y < 12

3 + 4y < 12

2. Plug in your y value (2 in this circumstance) and solve:

3 + 4(2) < 12

3 + 8 < 12

3. Solve

3 + 8 = 11

11 < 12
