Jim, Carla and Tommy are members of the same family. Carla is 5 years older than Jim. Tommy is 6 years older than Carla. The sum of their three ages is 31 years. How old is each one them?

Answers

So,

We'll solve it with only one placeholder, since that's simpler.

Jim's age = J
Carla's age = C
Tommy's age = T

J = base
Carla's age = J + 5
Tommy's age = Carla's age + 6 or J + 5 + 6 or J + 11

Sum of ages = 31
(J) + (J + 5) + (J + 11) = 31

3J + 16 = 31

Subtract 16 from both sides
3J = 15

Divide both sides by 3
J = 5

Carla's age = J + 5
Carla's age = 10

Tommy's age = Carla's age + 6
Tommy's age = 10 + 6 or 16

5 + 10 + 16 = 31
15 + 16 = 31
31 = 31 This checks.

Jim is 5.
Carla is 10.
Tommy is 16.

lets
Jim x years old
Carla (x+5) years old
Tommy (x+5)+6 years old
sum is x+(x+5)+(x+5)+6=31 years old
3x+16=31
3x=15
x=5 - age of Jim
x+5=5+5=10 - age of Carla
x+5+6=16 - age of Tommy

The resistance (R) in a wire increases when the length of the wire (L) increases. Write the correct equation for this scenario, and solve for when the length is 1. Length Resistance 10 2 15 3 a. R = 20 over L; R = 20
b. R = .2L; R = 5
c. R = .2L; R = .2
d. R = 20 over L; R = 5

Answers

Answer: c. R = 0.2L ; R =0 .2

Step-by-step explanation:

Given: When length of wire is $L_1=$ 10 units, then resistance of wire $R_1=$ =2 ohm

When length of wire is $L_2=$ 15 units, then resistance of wire $R_2=$ =3 ohm

Since, the resistance (R) in a wire increases when the length of the wire (L) increases. Therefore, they are directly proportional.

$(R)/(L)=(R_1)/(L_1)$

$(R)/(L)=(2)/(10)\n\Rightarrow\ R=0.2L$

Now, for Length L=1 unit, we have

$R=0.2(1)=0.2$

Please answer ASAP! An explanation is a MUST requirement in order to receive points and the Brainliest answer! Thank you.

The first step we can take to find the simplest form of this inequality is to subtract 3 from both sides

$(1)/(2)$ n + 3 < 5

$(1)/(2)$ n + 3 - 3 < 5 - 3

$(1)/(2)$ n < 2

So now we have a simpler version to work with.
To further simplify, we can divide both sides by $(1)/(2)$ . Dividing by fractions is hard though, so smart people have found out that dividing by a fraction is the same as multiplying by that same fraction's reciprocal.

$(1)/(2)$ n / $(1)/(2)$ < 2 / $(1)/(2)$

$(1)/(2)$ n * 2 < 2 * 2

Now, we can work it out to find the completely simplified inequality, which would simply be

n < 4

The character '<' represents that the number being represented by the variable is less than the number that follows that character. On a proper number line, this is represented by an open circle above the number on the right of the inequality with an arrow pointing the same direction on the number line that the point of the inequality symbol is facing.
If that doesn't make sense, imagine the inequality symbol as the head of an arrow.

<====<<

So the arrow would be pointing to the left, with an open circle above the 4. The only choice listed that represents this is the second option down.
Option B is your correct answer choice.
Hope that helped! =)
