Answer:Simplifying
6 + -2x = 6x + -10x + 6
Reorder the terms:
6 + -2x = 6 + 6x + -10x
Combine like terms: 6x + -10x = -4x
6 + -2x = 6 + -4x
Add '-6' to each side of the equation.
6 + -6 + -2x = 6 + -6 + -4x
Combine like terms: 6 + -6 = 0
0 + -2x = 6 + -6 + -4x
-2x = 6 + -6 + -4x
Combine like terms: 6 + -6 = 0
-2x = 0 + -4x
-2x = -4x
Solving
-2x = -4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4x' to each side of the equation.
-2x + 4x = -4x + 4x
Combine like terms: -2x + 4x = 2x
2x = -4x + 4x
Combine like terms: -4x + 4x = 0
2x = 0
Divide each side by '2'.
x = 0
Simplifying
x = 0
Step-by-step explanation:
12x - 5y = 2
12x - 12x - 5y = -12x + 2
-5y = -12x + 2
-5 -5
y = 2.4x - 0.4
y - 3 = 2.4(x - 3)
y - 3 = 2.4(x) - 2.4(3)
y - 3 = 2.4x - 7.2
+ 3 + 3
y = 2.4x - 4.2
Answer:
C) The third table. K= 5
Step-by-step explanation:
1) Below there are the missing data:
A proportional relationship through a constant k. It is obtained when we divide:
2)In this case, when we divide the temperature (T) by the time (h).
3)So, examining the table below we are searching for a ratio k common to all measures (temperatures over hour).
<u>Sampe : Total</u>
25 : 750
(÷25) (÷25)

7 : 210
Answer: (a) There is a total of 210 orange cakes made on Monday.
The sample is 5 when corrected to the nearest whole number.
⇒Smallest possible number is 4.5
Total orange cakes baked on Tuesday = 4.5 x 30 = 135
P(Orange Cake) = 135/750 = 9/50
Answer: (b) The probability is 9/50
