Answer:

The numbers of boys in one grade are 60 .

Step-by-step explanation:

As given

In one grade of 150 students .

The ratio of boys to girls is 2:3.

Let us assume that the scalar multiple of boys and girls be x.

Thus number of boys = 2x

Number of girls = 3x

Than the equations becomes

2x + 3x = 150

5x = 150

x = \frac{150}{5}

x = 30

Thus number of boys = 2 × 30

                                    = 60

Therefore the numbers of boys in one grade are 60 .

2+3 = 5

150/5 = 30

30*2 = 60

There are 60 boys in that grade.

Select all the true statements. Triangle A B C where the measure of angle A is 2 x plus 1 degree, angle B is x degrees, and angl
Step2247 [10]

Answer:

B= 41; C  = 56; A = 83

Step-by-step explanation:

Given

A = 2x + 1

B = x

C = x + 15

Required

Arrange the angles from smallest to largest

First, we need to determine the value of x.

Since, it is a triangle:

A + B + C = 180

Substitute values for A, B and C

2x + 1+ x + x + 15 = 180

Collect Like Terms

2x + x + x = 180 - 15 -1

4x = 164

Solve for x

x= 164/4

x= 41

Solve for A, B and C

A = 2x + 1

A = 2 * 41 + 1

A = 82 + 1

A = 83

B = x

B= 41

C = x + 15

C  = 41 + 15

C  = 56

From Smallest to Largest, we have:

B= 41; C  = 56; A = 83

You have two pieces for fabric. One piece is 6 feet wide and the other piece is 7.5 feet wide. You want to cut both pieces into
My name is Ann [436]

Answer:

<em>Strips should be </em><em>1.5 ft wide.</em>

Step-by-step explanation:

Given:

Width of 1st piece = 6 ft

Width of 2nd piece = 7.5 ft

To find:

To find the maximum width possible to make strips of equal size from both the pieces.

Solution:

This problem can be visualized as if we are given two numbers and we have to find the Highest common factor for both of them i.e. HCF of 6 and 7.5 will be our answer.

Let us try to factorize the given factors:

7.5 = 3 \times 2.5 = \underline {3 \times 0.5} \times 5

6 = 3 \times 2 = \underline {3 \times 0.5 }\times 2

The common factors are highlighted above as underlined.

Therefore, the answer is 3 \times 0.5 = <em>1.5 ft </em>

<em></em>

<em>Strips should be </em><em>1.5 ft wide.</em>

I need solving 4.8 (x+4)=2.6
victus00 [196]
<span>4.8 (x+4)=2.6
Use distributive property
4.8x + 19.2= 2.6
Subtract 19.2 from both sides
4.8x = -16.6
Divide 4.8 on both sides so that the only thing remaining on the left side is the variable x.
Final Answer: x = -3.458</span>
