Answer:
x = 97
y = 83
Step-by-step explanation:
y = 83 (being the vertically opposite angle )
y + x = 180 (being co-interior angle)
or,
83 + x = 180
or,
x = 180 - 83
.•. x = 97
Answer:
t= -4
Step-by-step explanation:
t/2-16= -18
first add 16 to both sides
t/2-16+16= -18+16
t/2= -2
now multiply both sides by 2
(t/2)2=-2(2)
t= -4
answer check:
substitute the variable for -4
-4/2-16= -18
-4/2= -2
-2-16= -18
-18= -18
Represent and then add up these consecutive, positive, even integers:
x + (x+2) + (x+4) + (x+6) = 116
Then 4x + 12 = 116, or 4x = 104. Then x=26.
First integer is 26; second is 28; third is 30; fourth is 32.
Add these up. If the sum = 116, you'll know these answers are correct.
22÷2/3 =33.000000003-13=20.000000003 (about 20)
check:
20+13=33
33x2/3=22
answer: x=20
y= kx
k= y/x
k= -3/4
make the constant K the subject
