Answer:

2x+100=522

Step-by-step explanation:

Let the no. of boys be x

We are given that there are 100 more girls than boys.

So, No. of girls = x+100

Total number students = x+x+100

                                      = 2x+100

We are given that The freshman class at Central High totals 522 students

So, equation becomes : 2x+100=522

Hence an equation can be used to find the number of boys is  2x+100=522

Answer:

The required equation is (1) and the number of boys is 211.

Step-by-step explanation:

Let the number of boys be x.

It is given that there are 100 more girls than boys. It means the number of girls is x+100.

The total number of students is 522.

Number of boys + Number of girls = 522

x+(x+100)=522          ... (1)

Combine like terms.

2x+100=522

Subtract 100 from both the sides.

2x+100-100=522-100

2x=422

Divide both sides by 2.

x=211

Therefore the required equation is (1) and the number of boys is 211.

Order 34 × 102, 1.2 × 107, 8.11 × 10–3 and 435 from least to greatest.
andrey2020 [161]
I will assume that this question is about scientific notation (also assuming that the first number is 3.4*10^2), where you can arrange the numbers by the exponent of the 10, so from least to greatest:
8.11*10^{-3}, 3.4*10^{2}, 435, and 1.2*10^{7}

3 quarts, because 12 is how many cups you have, and there are 4 cups in a quart. 12/4 is 3, so 3 quarts.

andrey2020 [161]
3.5 hours: $10 because if a 1/2 hour equaled 1.25 : 3.5 hours would give you $7.75
