Answer:

Tim has -8 points.

Step-by-step explanation:

15 - 23

Another way to solve for this is reversing the order the numbers are shown:

Answer:

50 degrees

Step-by-step explanation:

All three angles in a triangle add up to 180 degrees. If you know the measure of two angles, add them together and subtract the sum from 180.  

45+85=130.  Then, subtract 130 from the total, or 180.   180-130=50. The measure of the third angle of the triangle is 50 degrees.

Observation from input and output values:

Since each output is double of corresponding input, the missing output is:

6x² + 4 - 7x - 2x³

This is the simplest form for this equation.

Answer:

False.

Step-by-step explanation:

.

17+1= 18

12= -6

12-17= -5 + 1 =-4.

Answer:

False

Step-by-step explanation:

12- (17 + 1) = (12 - 17) + 1

PEMDAS says parentheses first

12- (18) = (-5) + 1

Then add and subtract

-6 = -4

They are not equal

Answer:

80.77777778

Step-by-step explanation:

when dividing 727 by 9, think about how many times does 9 go into 7? none.

next how many times does 9 go into 72? 8 times!

but since we have established 9 cannot go into 7 we need to know how many times does 9 go into 727, since it goes into 72 8 times already try adding a zero behind that 8. So what is 80(9)? it's 720. So the answer would be 720 with a remainder of 7. :)

Sorry i think like that the answer n sorry my write bad.

Thaks for your poin

Answer:

x is all real numbers

Step-by-step explanation:

4(x + 1) = 4x + 4

Distribute

4x+4 = 4x+4

Subtract 4x from each side

4x+4-4x = 4x+4-4x

4=4

This is always true so there are infinite solutions

x is all real numbers

Answer:

10

Step-by-step explanation:

[tex]\frac{1}{3}[/tex] × 18 = 18 ÷ 3 = 6

[tex]\frac{2}{5}[/tex] × 40 = (40 ÷ 5) × 2 = 8 × 2 = 16

Difference = 16 - 6 = 10
