Alvin's age is three times Elga's age. The sum of their ages is 104. What is Elga's age?

Answers

Answer: Alvin is 78, Elga is 26

Step-by-step explanation:

Let's first start by naming the variables:

a = Alvin's age

e = Elga's age

a = 3e

a + e = 104

substitute a (in the second equation) as 3e

3e + e = 104

4e = 104

e = 26

Substitute e as 26 into either equation

a = 3(26)

a = 78

divide 1/2 and 3/4 and it can not be a mixed number.

Answers

Answer:

Many options - 4/6 or 2/3 or 0.66

Step-by-step explanation:

When dividing fractions, we use KCF (keep, change, flip) so our new equation is 1/2 x 4/3. Just multiply! Your answer should be 4/6, and if it needs to be simplified, the answer is 2/3. The answer as a decimal is 0.66 !

Answer:You first would do 1/2 x 4/3 becuase when dividing numbers you use the keep change and flip method. So 1/2 you keep, you change the division sign into a multiplication sign and then 3/4 you flip into 4/3. After that you should have 1/2 x 4/3 and that gets you 4/6. So 4/6 would be your answer but simplified it would be 2/3. - Hope this helps!

In the below figure angle abc is 69 degree, angle acb is 31 degree so find the angle bdc

Answers

Answer:

[tex]\angle BDC=80^{\circ}[/tex]

Step-by-step explanation:

We are given that

[tex]\angle ABC=69^{\circ}[/tex]

[tex]\angle ACB=31^{\circ}[/tex]

We have to find the angle BDC.

In triangle ABC

Sum of interior angles of triangle=180 degrees

[tex]\angle ABC+\angle ACB+\angle BAC=180^{\circ}[/tex]

[tex]69+31+\angle BAC=180[/tex]

[tex]100+\angle BAC=180[/tex]
