The markup is an integrated cost of the price of a product that goes to the profit of the seller. In this case, a mark up of 25% is added to a calculator costing $15. The total cost then is $15*1.25 or equal to $18.75. In this case, a $3.75 is the profit.

-12 -4x + 3 = -1 what is the value of x
Vinil7 [7]

Answer:

Its -2

Step-by-step explanation:

Let's solve your equation step-by-step.

−12−4x+3=−1

Step 1: Simplify both sides of the equation.

−12−4x+3=−1

−12+−4x+3=−1

(−4x)+(−12+3)=−1(Combine Like Terms)

−4x+−9=−1

−4x−9=−1

Step 2: Add 9 to both sides.

−4x−9+9=−1+9

−4x=8

Step 3: Divide both sides by -4.

−4x

−4

=

8

−4

x=−2

Find the size of each of the angles marked with letter​​
GuDViN [60]

Answer:

angle l = 115

angle k = 115

angle j = 114

angle i = 66

Step-by-step explanation:

angle l = it is opposite to 115 so its the same

angle k = opposite opposing angles with angle l

angle j = 180-66=114 (between 2 parallel lines the sum of 2 angles is 180)

andle i = 180-114=66 (straight line = 180 degrees so subtract angle j to get i)

Evaluate 10C4. Type a numerical answer in the space provided. Do not type spaces in your answer.
SOVA2 [1]
10C4 represent the Combinations of 10 objects taken 4 at a time. 

The formula for nCr is:

nCr= \frac{n!}{r!(n-r)!}

In the given case, n=10 and r=4. Using these values we get:

10C4= \frac{10!}{4!(10-4)!} \\  \\ 
= \frac{10!}{4!*6!} \\  \\ 
=210

This means we can make 210 combinations of 10 objects taken 4 at a time.

25d-16=4d+26<br> whats d?
Sergio039 [100]
For this question you should first add -4d on both sides of the equation and then add +16 on both sides:
25d - 4d = 26+16 
21d = 42 
d = 42/21 
d = 2 :)))
I hope this is helpful
have a nice day
