Answer:
x = 1
Step-by-step explanation:
The two angles, ∠HGI & ∠IGF, when combined, will result in ∠HGF.
Note:
m∠IGF = 135x
m∠HGI = 26x
m∠HGF = 161°
Set the equation:
m∠IGF + m∠HGI = m∠HGF
Plug in the corresponding terms to the corresponding variables:
135x + 26x = 161
Combine like terms:
(135x + 26x) = 161
161x = 161
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 161 from both sides:
(161x)/161 = (161)/161
x = 1
1 is your answer.
~
x = 161/161 = 1
Answer:
7/12
Step-by-step explanation:
To find the probability of drawing a blue marble you need to find how many marbles there are in total.
So you have to add 3 red marbles, 7 blue marbles, and 2 green marbles to get the total.
So 3 + 7 + 2 = 12
There are 12 marbles in total so now you have to find how many blue marbles there are.
There are 7 blue marbles out of 12 marbles.
Now you have to put this as a fraction to see if it can be simplified.
7/12 cant be simplified, so the probability of drawing a blue marble is 7/12.
Answer:
0.33
Step-by-step explanation:
Equal to because they are both still a pound in weight :D
He needed to divide instead of subtracting it on the last step.
