D = 117
because angle 63 = angle 37+a because they are vertical angles,
therefore angle angle 37+a= angle b because they are corresponding angles
so if angle b=63 then angle d=117, so that together they equal 180, a supplementary angle.
Answer:
x=2,y=2
Step-by-step explanation:
This question is a simultaneous equation
So let's solve
3x+y=8...(1)
2x+2y=8....(2)
Multiply (1) by 2
6x+2y=16...(3)
Substrate (2) From (3)
4x=8
Let's make x the subject of formula by dividing both sides by 4
x=2
So let's substitute the value of x into (1)
3x+y=8
3(2)+y=8
6+y=8
y=8-6
y=2
Therefore x is 2,y is 2
Answer:
69+x=180 then u get answer but when u get that answer u di 69 times x

Y= # of pencils
z= # of pens
1y + 1.50z = 7
Total # of pencils and pens combined equals 6
4 pencils = $4
2 pens = $3
$4 + $3 = $7
4 pencils + 2 pens = 6 items total
