Answer:
C
Step-by-step explanation:
To Solve, just cube the terms on the right side to see if they go back to the number on the left.
The first part is true because multiplying 11 * 11 * 11 = 1331.
The second part is true because multiplying 5 * 5* 5 = 125.
The third part is false because multiplying 8 * 8 * 8 = 512.
The fourth part is true because multiplying 1 * 1* 1 = 1.
Answer:
8.06
Step-by-step explanation:
use distance formula
If we assume that
x isthe number of multiple choice questions, and y is the number of word problems, we can write a system of equations like:
{ x + y = 38
{ 2x + 5y = 100
If we multiply the first equation by -2 we get:
{ -2x-2y = -76
{ 2x + 5y = 100
Now if we add both equations we get only equation with 1 unknown (y) :
3y = 24 ⇒ y = 8
Substituting the calculated value to the first equation we get:
x + 8 = 38 ⇒ x = 30
The solution:
{ x = 30
{ y = 8
means that:
The test had 30 multiple choice questions, and 8 word problems.
1 line, because it’s between 2 points
