Answer:

x=18

y=24

Step-by-step explanation:

Let the number of boys in the camp = x

Number of girls = y

\frac{x}{y}=\frac{3}{4}\\x=\frac{3y}{4} -----(A)

Total number of students = 42

x+y=42

Putting value of x from A

\frac{3y}{4}+y=42\\\frac{3y+4y}{4}=42\\\frac{7y}{4}=42\\y=\frac{42 \times 4}{7}\\y=24

Putting this value in A and solving for x

x=\frac{3 \times 24}{4}\\x=18

What is the solution to this system of equations? 2t + w = 10 4t = 20 − 2w A. It has no solution. B. It has infinite solutions.
joja [24]

Answer:

<h3>B. It has infinite solutions</h3>

Step-by-step explanation:

Given the system of equations:

2t + w = 10 ..... 1

4t = 20 − 2w ... 2

From 1:

w = 10-2t ...3

Substitute 3 into 2 to have;

4t = 20 - 2(10-2t)

4t = 20-20+4t

4t = 4t

Let t = k

Substitute t = k into 1 and get w;

From 1: 2t + w = 10

2k + w =10

w = 10 - 2k

<em>k can take any integers. This shows that the solution to the equation is infinite</em>
