Just by the language difference means subtract,
Y^2-25 is the difference of squares
factored it's the sum and difference of their square roots
(x+5) (x-5)
2x + 3y/4 = 5....multiply everything by 4
8x + 3y = 20
3y = -8x + 20
y = -8/3x + 20/3 or y = (-8x + 20) / 3
Assume that pi is approx. 3.14. Then 86.92 = approx. 27 2/3 times pi, or
86.92 is approx. equal to 83pi/3.
Answer:
1933
Step-by-step explanation:
9 x (1 + 345) - 6 - 8 + 48 x 23 - 77
Use BODMAS method to solve these type of equation
B - Brackets
O - Power
D - Division
M - Multiplication
A - Addition
S - Subtraction
_________________________________________________________
Brackets - 1 + 345 = 346
Multiplication
9 x 346 = 3114
48 x 23 = 1104
Lets rewrite the equation now
3114 - 6 + 1104 - 77
Addition
6 + 1104 = 1110
Subtraction
3114 - 1104 = 2010
2010 - 77 = 1933
Answer = 1933
