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
Step-by-step explanation:
Pi (Ratio of the Circumference of a Circle to Its Diameter) Circles are all similar, and "the circumference divided by the diameter" produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).
Answer:
x=1 y=7
Step-by-step explanation:
−5x+2y=9
y=7x
Substitute the second equation into the first
-5x +2(7x) = 9
Distribute
-5x +14x = 9
Combine like terms
9x=9
Divide by 9
9x/9 =9/9
x= 1
Now find y
y = 7(1)
y = 7
