Answer:
Step-by-step explanation:
Where the question at
(9+x)/3x = 5/6
(9+x)/x = 15/6 (then distribute out x on bottom)
9/x + 1 = 15/6
9/x = 1.5
x = 9/1.5
x=6

2^3 + 30 / (10 - 15 / 3)
Do everything in brackets first
First we do 15/3 which is = 5
Then 10 - 5 = 5
Now we have 2^3 + 30 / 5
Next we will do exponents so we simplify 2^3 which is the same as 2×2×2 = 8
8 + 30 / 5
Next we do division so 30/5 = 6
Finally, 8 + 6 = 14
Answer:
$199.89
Step-by-step explanation:
The bike costs 266.52
The parents are contributing one fourth of this (1/4)
We need to find 1/4th of 266.52
Divide 266.52 by 4 to find out how much Justin's parents are contributing to the bike
The answer is 66.63
Now subtract 66.63 from 266.52
Justin has to pay a total of 199.89
Answer:
sin A = 4/5
cos A = 3/5
Step-by-step explanation:
SOHCAHTOA
cot A = 1/tan A
tan A = opp/adj
cot A = 1/tan A = adj/opp
cot A = 3/4
adj = 3; opp = 4
adj^2 + opp^2 = hyp^2
3^2 + 4^2 = hyp^2
9 + 16 = hyp^2
hyp = 5
sin A = opp/hyp
sin A = 4/5
cos A = adj/hyp
cos A = 3/5
Answer:
sin A = 4/5
cos A = 3/5
