Answer:
12 Math Club students
Step-by-step explanation:
2 vans each holding 6 students = 12 because 2x6 = 12
Simplifying
5C + -4 + -2C + 1 = 8C + 2
Reorder the terms:
-4 + 1 + 5C + -2C = 8C + 2
Combine like terms: -4 + 1 = -3
-3 + 5C + -2C = 8C + 2
Combine like terms: 5C + -2C = 3C
-3 + 3C = 8C + 2
Reorder the terms:
-3 + 3C = 2 + 8C
Solving
-3 + 3C = 2 + 8C
Solving for variable 'C'.
Move all terms containing C to the left, all other terms to the right.
Add '-8C' to each side of the equation.
-3 + 3C + -8C = 2 + 8C + -8C Combine like terms: 3C + -8C = -5C<span>-3 + -5C = 2 + 8C + -8C
Combine like terms: 8C + -8C = 0
-3 + -5C = 2 + 0
-3 + -5C = 2
Add '3' to each side of the equation.
-3 + 3 + -5C = 2 + 3
Combine like terms: -3 + 3 = 0
0 + -5C = 2 + 3
-5C = 2 + 3
Combine like terms: 2 + 3 = 5
-5C = 5
Divide each side by '-5'.
C = -1
Simplifying
C = -1</span>
<span><span>If you would like
to </span>divide 42 in the ratio of 1 : 2 : 3, you can do this using the following
two steps:<span>
<span>First, add the numbers: </span>1 + 2 + 3 = 6
<span>Second, divide and multiply: 1</span> / 6 * 42 = 7
2 / 6 * 42 = 14
3 / 6 * 42 = 21
<span>The result you are looking for is </span>7 : 14 : 21<span>.</span></span></span>
2(6+(x+3)) * (2-x) = 4 is what it looks like. twice meaning two of the following part,
then x needs increased by 3 before being added to 6
times (multiply)
the difference of 2 and x
all this = 4
Answer:
x = 4,
x = -2
Step-by-step explanation:
( x - 4 ) ( x + 2 ) = 0
Find out when the equation is 0,
When x = 4,
substitute in 4 for x,
( 4 - 4 ) ( 4 + 2 ) = 0
(0) ( 6) = 0 (any number multiplied by 0 is 0).
When x = -2
Substitue in -2 for x,
( -2 - 4 ) ( -2 + 2 ) = 0
(-6) (0) = 0 (again, any number multiplied by 0 is 0).
