Juan is three times as old as Gabe and Gabe is six years older than Catherine. If the sum of their ages is 149, how old is each

cestrela7 [59]

Answer:

Juan = 93 years.

Gabe = 31 years.

Catherine = 25 years.

Step-by-step explanation:

Let the age of Juan = J

Let the age of Gabe = G

Let the age of Catherine = C

Translating the word problem into an algebraic equation, we have;

$J = 3G$ ..........equation 1

$G = C + 6$ ........equation 2

$J + G + C = 149$ ........equation 3

We would solve the linear equations by using the substitution method;

Substituting equation 2 into equation 1;

$J = 3(C + 6)$

$J = 3C + 18$ ........equation 4

Substituting equation 2 and equation 4 into equation 3;

$(3C + 18) + (C + 6) + C = 149$

Simplifying the equation, we have;

$5C + 24 = 149$

$5C = 149 - 24$

$5C = 125$

$C = \frac {125}{5}$

C = 25 years.

To find G; from equation 2

$G = C + 6$

Substituting the value of "C" into equation 2, we have;

$G = 25 + 6$

G = 31 years.

To find J; from equation 1

$J = 3G$

Substituting the value of "G" into equation 1, we have;

$J = 3 * 31$

J = 93 years.

Therefore, Juan is 93 years old, Gabe is 31 years old and Catherine is 25 years old.

Not sure how to do this, fill in the blank to make the two fractions equivalent. 3/5 = ?/25

AVprozaik [17]

3/5=x/25
Multiply both sides by 25 to get: x = 25(3/5)x = 15

Carolyn sees 442 people lined up at the theater to see a movie. The movie theater has 7 rows of seats. How many people sit in ea

Serhud [2]

Answer:

Step-by-step explanation:

First you need to write it down. Now, 1st step of the math, how many times will 7 go into 4? 0 times. So you have to do how many times 7 goes to 44. It goes in 6 times bc 7 times 7 is 49. Now, subtract 42 form 44 which is 2. Bring down the 2, you get 22. 7 goes into 22 3 times, subtract 21 from 22. One. So your answer is 63 remainder one!

How many significant figures will there be in the answer to the following problem? 7500×45.0879

Alchen [17]

Two significant Figures I believe because you want to go with the least amount of sig figs that are already in your problem which would be 2 in 7500 because the zeros are not significant
