Tanzania [10]

First, turn 70% into a decimal by dividing 70 by 100.

70% ⇒ 0.70

Multiply 120 by 0.70.

120 × 0.70 = 84

Now we know that 84 students are involved in extracurricular activities. Subtract 84 from 120 to find the amount of students who are <em>not</em> involved in extracurricular activities.

120 - 84 = 36

<h2>Answer:</h2>

Serga [27]

Answer: The system of equation is,

2 ( x + y ) = 50

x = 2 y - 5

Step-by-step explanation:

Let x represents the length of the rectangular brownie and y represents the width of the rectangular brownie.

Thus, the perimeter of the brownie = 2 ( x + y )

But, According to the question,

Perimeter of the brownie = 50,

2 ( x + y ) = 50

The length of the brownie is 5 less than twice the width,

That is, x = 2 y - 5

Thus, the required system of equation is,

2 ( x + y ) = 50 , x = 2 y - 5

1.) top row: 100 200 300 400 500 600. Bottom row: 5 10 15 20 25 30
2. Each ratio is just the top row divided by the bottom row. So the second thing in the ratio would be 200/10, the third one 300/15, etc. Each ratio is equal to 20.
3.) if x is gallons of gas used, y is distance driven. the equation that describes this relationship is y=20x.
