The answer is -3 because 24/-8=-3

The answer is -3. 24/8=3 and with 24/-8 all you do differently is place a negative sign in front of the 3.

Which statement describes the solution to the equation a+5(2a−1)+3=11a−2 ?A.The equation has no solution.

b. The equation has exactly one solution, a=2 11 .

C. The equation has exactly one solution, a=−4 .

D. The equation has infinitely many solutions.

Answers

a+5(2a-1)+3=11a-2
First thing to do is distribute
5*2a=10a
5*-1=-5
a+10a-5=11a-2
Add the similar numbers together
11a-5=11a-2
Then subtract
11a-11a
-5=-2
This equation has no solutions
If it had infinity solutions then both numbers on each side would equal the same, ex: -5=-5

1st distribute

a + 10a - 5 + 3 = 11a -2

Then combine like terms

11a-2 = 11a-2

0=0

Mrs Smith has 12 times as many markers as color pencils the total number of markers and colored pencils is 78 how many markers does Mrs Smith have

Answers

x = markers
y = colored pencils

12x = y

x= 72
y = 6

Okay, so what I did was divide 78 by 12 (to find the number of colored pencils) which gave me 6.5. You can't have half a colored pencil, so I rounded the number down to get 6. To find the number of markers, I multiplied 12 and 6 (12x = 6) which gave me 72. To check my answer I added the two amounts, 72 + 6, which gave me 78.

What is (-0.75x + 6) -(2.5x -1.9)

Answers

The solution to the expression (-0.75x + 6) -(2.5x -1.9) is -3.25x + 7.9

How to evaluate the expression

From the question, we have the following parameters that can be used in our computation:

(-0.75x + 6) -(2.5x -1.9)

Open teh brackets

So, we have

(-0.75x + 6) -(2.5x -1.9) = -0.75x + 6 -2.5x + 1.9

Evaluate the like terms

So, we have

(-0.75x + 6) -(2.5x -1.9) = -3.25x + 7.9

Hence, the solution is -3.25x + 7.9
