Nick is now seven times as old as Harry. In 6 years, Nick will be five times as old as Harry. How old will Harry be in 6 years?

Papessa [141]

<span>Let x represent Harry's age now, and Nick's age now is 7x. [t]
In 6 years, Harry is x + 6 , and it is given that Nick's age will be 5(x+6). [t+6]

Combining [t] and [t+6], 7x + 6 = 5(x+6).
So the formula 7x + 6 = 5(x+6) represents the problem.

And x = 12 , so Harry's age in 6 years will be x +6 or 18 years .

I hope this helps!</span>

The primers you used in lab amplified 145 base pairs that were adjacent, but not included in the repeat. If you used a different

Elanso [62]

If your PCR product size was 172 and there were 130 base pairs next to a 14 base pair repeat, then there are 3 repeats.

Given that the newly used primer amplifies 130 base pairs that are near

(a) 14 base pair and

(b) the size of the pcr product is 172

Size = (number of base pairs * number of repetitions) + Initial/Primer Amplicon Value

172 = (14 * x) + 130

172 -130 = 14x

42 = 14x

3 = x

Therefore, we can say that the PCR product has 3 repeats.

Name the property that the statement illustrates.

kolezko [41]

Answer:

Transitive property of segment congruence

Step-by-step explanation:

The reflexive, symmetric, and transitive properties are the criterion for an equivalence relation. In terms of congruence,

The reflexive property states that $\overline{XY} \cong \overline{XY}$ (a segment is congruent to itself)
The symmetric property states that if $\overline{AB} \cong \overline{CD}$ , then $\overline{CD} \cong \overline{AB}$ (this is essentially commutativity)
The transitive property states that if $\overline{AB} \cong \overline{CD}$ and $\ovelrine{CD} \cong \overline{EF}$ , then $\overline{AB} \cong \overline{EF}$ .
