Let's make the inequality.
The sum of twice a number and 2. We're adding and multiply. X will be the number. 2x+2
Is greater than 4. We'll be using the greater than sign. >4; let's put it together.
2x+2>4; let's solve. First by subtracting two on both sides. 2x>2; let's divide by 2. x>1
So, the inequality is 2x+2>4. To solve it, it is x>1.
Answer:
25:64
Step-by-step explanation:
surface : 4×pi×R^2
R1 = 5x
R2 =8x
4piR1^2 / 4piR2^2 = R1^2/R2^2 = 5x^2/8x^2 = 25x^2/64x^2 = 25/64
5 cm = 2km
Scale= 5 cm : 200000 cm
= 1 : 40000
a. 1 : 40000 = x : 500000
x = 12.5 cm
b.1 : 40000 = 2 : x
x = 80000 cm
x = 0.8 km
Answer:
The answer is 92%
Step-by-step explanation:
448/487=.92
is already in simplest form because 23 is a prime number, which means that it is only divisible by 1 and itself (23). Hope this helps! :)
