Answer:
41
Step-by-step explanation:
40+16+y=180°
56+y=180°
y=180-56
y=124°
124+15+x=180°
139+x=180°
x=180-139
<em>x=41°</em>
Answer:128
Step-by-step explanation:
y+yx
When x=15, y=8
8+(15×8)
=8+120=128
703.005 is less because .005 is less than .050
Here the question is simple.
All because, we only need to find the value of x.
We are given two equations.
5x + 6 = 10 and 10x + 3 =?
So, we will find the the value of x in the first equation, so that we can substitute the value of x in the second one and there we are with the answer.
5x + 6 = 10
For finding the value of x, all we have to do is,
Transpose the number 6 to 10
Therefore. 5x = 10 - 6 ( Take the equal sign as The Magic Bridge on which if anyone crosses it , will change its sign.)
So we have,
5x = 4
So x = 4/5 ( Multiplication will change to division after crossing the equal sign)
( Doubtful? Substitute the value of x and try!)
Now that we got the value of x,
We can just simply substitute the value of x in the second equation.
10x + 3 = ?
x = 4/5
10*4/5 +3 => 5 and 10 get canceled to 2 at the numerator.
By normal multiplication and then addition, we will get,
8 + 3 = 11
Hope this helps!!!! :)
Distance = 150 miles
Consumption of gas = 25 miles / gallon
Price = $3 / gallon
Calculation is done as follows:
Total cost = $3 / gallon (150 miles / (25 miles/gallon)) = $18
