Answer:
<h2>The value of a is 12.</h2>
Step-by-step explanation:
The equation is given by (a - 12)x = a + 8.
In order to get the solution of the equation, that is the value of x, the above equation is needs to be divided by a - 12. (a - 12) will be in the denominator.
The solution can not be found, if the value of a - 12 will be 0, that is a = 12.
I believe the answer for B is 1
Answer:
B
Step-by-step explanation:
all 3 angles of a triangle must equal 180 degrees, so if it tell you that there is a 68 degree angle, and a 90 degree angle(because if the right angle), then the last angle must be 22, because 180-(68+90)=22
Answer:
45 yellow ones, i think
Step-by-step explanation:
for every 2 green, there are 5 yellow
there are 18 green, so 9 pairs
9 times 5 = 45 (i multiplied by 5 because there are 5 yellow for each pair of green)
Y = 2x + 7
Function notation
f(x) = 2x + 7
