6. irrational because nothing times itself is 127.
7. a. 29 is the width plus two things that will equal 105 which would be two 52.2 lengths
b. 29, 52.2, 52.2 or 29, 29 69
8. a. 402 - 237(x/15)
b. 11
c. 12
9. no because it does not reach 90 when you add them together
10. rational because the decimal terminates
2x+7=?
X=6
2(6)+7=
12+7=19
In six years, the tree will be 19ft
2x+7=44
Minus seven on both sides
2x=37
Divide two from both sides
X=18.5
Thus, it will take 18 and a half years for the tree to reach 44ft
The given statement is "nine times five less than twice x".
So, twice of x can be written as 2x and nine times five is 9*5.
Now 9*5 less 2x means we need to take out 9*5 from 2x.
Hence, this statement will be converted into an algebraic expression as follows:
2x-9*5
Answer:
49
Step-by-step explanation:
Product of GCD and LCM = Product of the 2 numbers
Product of GCD and LCM = 7 × 140 = 980
One number is 20 so let the other number be N
20×N=7×140
20N=980
2N=98
N=49
so the other number is 49
