To solve this, you use the rule where AK x KC = DK x KB. In this case, 14(3+3X) = 12(4X+1). Then you solve like it's basic algebra. Your answer is then x=5. Or in this case answer choice D.

Part A

4 < 5 < 9 is given to us. Apply the square root to each term to end up with this inequality: sqrt(4) < sqrt(5) < sqrt(9)

So sqrt(5) is between sqrt(4) and sqrt(9)

-------------------

Part B

Simplify those two mentioned square roots

sqrt(4) = sqrt(2^2) = 2

sqrt(9) = sqrt(3^2) = 3

Therefore, sqrt(5) is also between 2 and 3

We can see this through using a calculator: sqrt(5) = 2.23607 approximately

-----------------

Part C

We can now say:

2 < sqrt(5) < 3

Multiply all three sides by 6

6*2 < 6*sqrt(5) < 6*3

So the expression 6*sqrt(5) is between 6 x 2 and 6 x 3

Sure enough, a calculator confirms this

6*sqrt(5) = 13.416408

since 6*2 = 12 and 6*3 = 18. We see that 13.416 is between 12 and 18.

1+4=5 2+5=12 3+6=21 8+11=? puzzle answer

Over [174]

The answer is 97. The first expression is 1+4=5. In the next expression, both numbers are increased by 1 while their sum is increased by 7: (1+1)+(4+1) = (5+7). 2+5=12. In the next expression, both numbers are increased by 1 again, but the sum is increased by the next odd number (which is 9): (2+1)+(5+1)=(12+9). 3+6=21. So, the series will look like this: 1+4=5. 2+5=12. 3+6=21.4+7=33. 5+8=46. 6+9=61. 7+10=78- 8+11=97.

Sam can mow a lawn in 40 minutes. Vanessa can mow the same lawn in 60 minutes. How long does it take for both Sam and Vanessa to

xxMikexx [17]

Answer:

As a reduced fraction: $\frac{120}{5}$ minutes, which is 24 minutes

Step-by-step explanation:

Sam's speed is 1 lawn in 40 minutes. Vanessa's speed is 1 lawn in 60 minutes. If they both work together, the total speed is:

$\frac{1}{40}+\frac{1}{60}=\frac{1(3)}{40(3)}+\frac{1(2)}{60(2)}=\frac{3}{120}+\frac{2}{120}=\frac{5}{120}$

Which means that the total speed would be 5 lawns in 120 minutes. To find the time it would take to mow one lawn at that speed, we need to invert that speed so we get minutes per lawn:

$\frac{120}{5}=24minutes$
