Answer:
1) 4
2) 3
3) 9
4) 6
5) 3/4
Step-by-step explanation:
5÷(4-3)×9-2
= 5÷1×9-2
= 5 × 9 - 2
= 43
You must solve the bracket first.After that,solve the multiplication and division,followed by addition and substraction if any.That's the theory to solve the right step
Answer:
Step-by-step explanation:
f(x)=3x²+5x+4
g(x)=3x
(f/g)(x)=f(x)/g(x)=(3x²+5x+4)/3x
Answer:
x = 31 and x = 15
Step-by-step explanation:
(a)
(3x + 31) and (2x - 6) are a linear pair and sum to 180° , then
3x + 31 + 2x - 6 = 180
5x + 25 = 180 ( subtract 25 from both sides )
5x = 155 ( divide both sides by 5 )
x = 31
(b)
3x and (4x - 15) form a right angle and sum to 90° , then
3x + 4x - 15 = 90
7x - 15 = 90 ( add 15 to both sides )
7x = 105 ( divide both sides by 7 )
x = 15
