The answer is 83. First divide 10 by 2, which is 5 for a remaining 85-5+3. 85 - 5 is 80 and 80 + 3 is 83.
Answer:
Correct to 1dp
127.3 cm = 127.0 cm
86.5 cm = 87.0 cm
Upper limits:
127.0 cm = 127.05 cm
87.0 cm = 87.05 cm
Lower Limits:
127.0 cm = 126.95 cm
87.0 cm = 86.95 cm
upper limit of perimeter of rectangle:
P = 2(l+w)
= 2(127.05 + 87.05)
= 2(214.1)
= 428.2 cm
lower limit of perimeter of rectangle:
P = 2(l+w)
= 2(126.95 + 86.95)
= 2(213.9)
= 427.8 cm
therefore;

Z=118 as vertically opposite angles are the same
x= (8x-50)
Answer:
Y=168
Step-by-step explanation:
Y varies directly as X
Y=kx
K is a constant
28=k2
K=28/2 =14
Y=14x
Y=14×12
Y=168
Write and solve an equation of ratios:
oil 8 x
---- = ---- = -----------
vin 5 7 liters
Then 5x = 56, and x = 56/5 liters (of vinegar)
