2x+7=11-2x (add 2x)
4x+7=11 (minus 7)
4x=4 (divide by 4)
x=1
Answer:
The irrational numbers are √1/2, √1/8 and √1/10
Step-by-step explanation:
Rational numbers are numbers that can be written as a simple ratio. If the ratio is simplified further into decimal, the numbers in the decimal do not occur repeatedly.
Irrational numbers are opposite. Irrational numbers are are numbers that cannot be written as a simple ratio. If the ratio is simplified further into decimal, the numbers in the decimal occur repeatedly.
Looking at the numbers given above,
1) √1/16 = 1/4 = 0.25
It is rational because it is expressed in simple ratio and the numbers in the decimal do not occur repeatedly.
2) √1/2 = 1/√2 = 0.70710678119
It is irrational because it cannot be expressed in simple ratio and the numbers in the decimal occur repeatedly.
3) √1/8 = 1/√8 = 0.35355339059
It is irrational because it cannot be expressed in simple ratio and the numbers in the decimal occur repeatedly.
4) √1/10 = 1/√10= 0.31622776602
It is irrational because it cannot be expressed in simple ratio and the numbers in the decimal occur repeatedly.
5) √1/4 = 1/4 = 0.5
It is rational because it is expressed in simple ratio and the numbers in the decimal do not occur repeatedly.
6 =2(x+8)-5x
6 =2x+16-5x
6-16=2x-5x
-10=-3x
10=3x
x=10/3
hence proved
Answer:
-17
Step-by-step explanation:
There are 43560 SF in an acre first you want to find the total SF witch is 43560x25=1089000 SF. also the common area will take up about 35% of the overall area so do .35x1089000=381,150 and subtract that from the overall SF witch gives you 707,850 then divide this by 25000 SF for the total number of lots that the developer can have on this property witch is 28 or 28.3 rounded to the tenths.
