Answer: 6
Explanation:
3(4-2) = 3(2) = 6
1. No answer ( may be due to incorrect question)
2. x = -3
y = 4
3. x= 4
y = 2
4.x = -63/40
y= -19/20
Step 1
Multiply equation 1 by the coefficient of x in equation 2
Multiply equation 2 by the coefficient of x I'm equation 1
(after completing this step you will derive equation 3 and 4 )
Step 2
Subtract equation 4 from equation 3
Step 3
Divide both sides of the equation by the coefficient of y
Step 4
substitute your value for y in equation 1 or 2
(after this you will derive the values of x)
Note : This method is for the Elimination of x

Answer:
is it asking how many times u would get then number 5 when u roll or asking how you would expect for the first 5 rolls?
Answer:
5% did not pass inspection
Step-by-step explanation:
Given


Required
Determine the percentage of parts that didn't pass inspection.
First, we need to calculate the number of those that didn't pass inspection.



Next, we calculate the percentage as follows:

The above formula is derived by dividing the number of parts that didn't pass inspection by the total machine inspected, then multiplied by 100%
So:




<em>5% did not pass inspection</em>
3x+17+5x=7x+10
Simplify:
3x+5x+17=7x+10
8x+17=7x+10
Get the variables on one side:
8x-7x+17=7x-7x+10
x+17=10
One-step equation:
x=-7
