Answer:
y=11
x=8
Step-by-step explanation:
This is Elimination
2x+2y=38
Subtract 2x on both sides 2y=-2x+38
Then Multiply 2(y=x+3) which equals 2y=2x+6
Solve by Elimination
2y=-2x+38
2y=2x+6
add the y's and since the x's are different those cancel out, then add 38 and 6.
then you do the equation 4y=44
divide both by 4
y=11
then you do 11=x+3
subtract 3 on both sides
x=8
and there you go
I hope this is how you wanted it solved

Answer:
0.3 in²
Step-by-step explanation:
This picture is NOT to scale. That 20° Angle looks more like 70°.
Area of the circle = 81pi = 254.469
20/360 of the circle = 1/18 = 14.137
Area of triangle = 13.851
14.137-13.851= 0.3 in²
First, assign a variable that you're looking for.
Let x = the larger number
Then x - 1 = the smaller number
The sum of x and x - 2 will equal to 226.
x + x - 1 = 226
2x - 1 = 226
2x = 228
x = 114
So, the smaller number is 112 and the larger number is 114.
