The correct equation for this given situation is,

⇒ 3x = 9

Where, x is number of students.

And, There are 27 strawberries did Sergio have.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Sergio divided his strawberries equally among 3 friends.

And, each friend received 9 strawberries,

Let Number of strawberries did Sergio have = a

Hence, We get;

⇒ a = 3 × 9

⇒ a = 27

Thus, There are 27 strawberries did Sergio have.

Answer:

y = x + 7

Step-by-step explanation:

This is a linear equation graph because the line is straight and it is going at a constant rate. You can just either add or subtract the dependent event or the y variable.  So I use the linear equation y = mx + b.

Use the y2 - y1 / x2 - x1 to find the slope. The slope is basically m.  You can use any coordinate for this.

I will use (2, 9) and (3,10) as the coordinates for an example.

So y2 = 10

y1 = 9

x2 = 3

x1 = 2

10 - 9 / 3 - 2 = 1/1 = 1

1 is the same thing as x.

So the slope is x.

Now in order to find b(or the whole number on the far right), you use one of the x and y coordinates.

For an example I will use (5, 12)

Now all I do is use the formula y = mx + b

y = 12

x = 5

m = 1.  M is the same thing as slope.

b is what I must find out.

So I write 12 = 1(5) + b

12 = 5 + b

Then you subtract 5 from 12

and you will get 7.

12 - 5 = 7

The b or the y intercept equals 7.

So the equation for this graph is y = x + 7

Simple bro! The hard part was the explanation.

The equation for the line is y=x+7

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.

Given here, the points on the line are (2,9) , (3,10) , (4,11) , (5,12) , (6,13)

Let's assume the the equation of the line is y=x+7 then putting on the points on the equation we get

(2,9)  9=2+7

(3,10) 10=3+7

Similarly the equation holds good for all the points in the graph.

Hence, The equation for the line is y=x+7

Answer:

Step-by-step explain

Option E will be the correct option.

  Condition for the balanced hanger,

Weights on left side = 4(weight of one square) + 2(weight of one triangle) + 2(weight of one circle)

Weights on right side = 2(weight of one square) + 1(weight of one triangle) + 3(weight of one circle)

Since, hanger is balanced,

Weights on the left side = Weights on the right side

4(weight of one square) + 2(weight of one triangle) + 2(weight of one circle) = 2(weight of one square) + 1(weight of one triangle) + 3(weight of one circle)

4x + 2(2.5) + 2(3) = 2x + 2.5 + 3(3)

4x + 2.5 + 2.5 + 3 + 3 = 2x + 2.5 + 3 + 3 + 3

    Therefore, Option E will be the answer.

Step-by-step explanation:

The Ratio of 1.5-inch screws to 2.5-inch screws = 36/12 = 12/4 = 6/2 = 3/1

A ratio is a relationship between two things when it is expressed in numbers or amounts.

Given that a carpenter needs 36 screws that are 1.5 inches long, 24 screws that are 2 inches long, and 12 screws that are 2.5 inches long.

According to question we get,

Ratio of 1.5-inch screws to 2.5-inch screws = 36/12

Equivalent ratios = 12/4, 6/2, 3/1

Hence, The Ratio of 1.5-inch screws to 2.5-inch screws = 36/12 = 12/4 = 6/2 = 3/1

Answer:

16

Step-by-step explanation:

Real length: 30 ft

Drawing length: 20 in.

Real width: 24 ft

Drawing width: x

30/20 = 24/x

3/2 = 24/x

1/2 = 8/x

x = 2 * 8

Answer:

Question 1: 8 bags

Question 3: $30

Step-by-step explanation:

Question 1: Since 2 bags of ice costs $3 you can find how many bags of rice you could get by doing this:        

                                                  2   4   6   8

                                                  3   6   9   12

The top shows he number of bags, and the bottom shows the price. So when you get to $12 you are at 8 bags. Therefore, 12$ will get you 8 bags of rice.

Question 3: Since 2 bags of rice costs $3 its easier to find the answer if you find how much it costs for 1 bag, to do this do 3/2 which equals, 1.5. So 1 bag costs $1.50. And since you need to find out how much 20 bags would cost, do 1.5 × 20, and this equals 30. Therefore 20 bags of rice will cost you $30.

X= -1

Step-by-step explanation:

[tex](\frac{1}{3} )(6x)+(\frac{1}{3} )(-15)=(\frac{1}{2} )(10x)+(\frac{1}{2} )(-4)[/tex]

(Distribute)

2x+−5=5x+−2

2x−5=5x−2

Step 2: Subtract 5x from both sides.

2x−5−5x=5x−2−5x

−3x−5=−2

Step 3: Add 5 to both sides.

−3x−5+5=−2+5

−3x=3

Step 4: Divide both sides by -3.

Which = -1
