Answer:

d > 5.5

d > 11/2

Step-by-step explanation:

To solve the inequality (find all possible values of "d" for the statement to be true), isolate "d". This means to separate it from all of the other numbers. Do this by performing reverse operations in reverse BEDMAS (brackets, exponents, division, multiplication, addition, subtraction) order.

12d + 34 > 100

12d + 34 - 34 > 100 - 34 Subtract 34 from both sides. It's the reverse operation for adding 34.

12d > 100 - 34 34 - 34 on the left side cancels out

12d > 66 Simplify 100-34

12d/12 > 66/12 Divide both sides by 12 to isolate "d"

d > 66/12 Reduce to lowest terms. 66 and 12 are both divisible by 6.

d > 11/2 Answer in lowest terms

d > 5.5 Answer as a decimal

Therefore, for 12d + 34 > 100 to be true, "d" must be greater than 5.5 or 11/2.

Answer:

$\text{D. }b^2-4ac>0$

Step-by-step explanation:

The equation $b^2-4ac$ represents the discriminant of a quadratic. It is the part taken from under the radical in the quadratic formula.

For any quadratic:

If the discriminant is positive, or greater than 0, the quadratic has two solutions

If the discriminant is equal to 0, the quadratic has one distinct real solution (the solution is repeated).

If the discriminant is negative, or less than 0, the quadratic has zero solutions

In the graph, we see that the equation intersects the x-axis at two distinct points. Therefore, the quadratic has two solutions and the discriminant must be positive. Thus, we have $b^2-4ac>0$ .

George bought 7.5 cases of pancake mix for his diner. A case contains 12 1.3-pound boxes. How many pounds of pancake mix did Geo

Ilya [14]

In order to get the answer to this problem, first we have to find out how many pounds does one case of pancake mix have. We know that one box has 1.3 pounds of pancake mix. We also know that one case has 12 boxes. So first, we multiply 1.3 to 12. The answer we will get is 15.6. One case of pancake mix has a total of 15.6 pounds of pancake mix. Now we also know there are 7.5 cases that George bought. So in order to get the total pounds George bought, we multiply 15.6 to 7.5. So all in all, George bought 117 pounds of Pancake Mix.
