No, Mateo is not correct because he is older than his brother which would make 41 a greater value than b. The correct statement would be ‘b < 41’.

Solve for x.. please help

Genrish500 [490]

The answer for this problem is that x = 60°, or B.

We can solve this problem by using our knowledge of quadrilaterals. In this problem, we need to know that the number of degrees in a quadrilateral is equal to 360, but, the formula to find the number of degrees in a polygon with n sides is (n-2) * 180.

Now that we know that the sum of the angles if 360°, we can add all the angles and solve for x. The angles with the squares are 90°.

2x° + x° + 90° + 90° = 360°

Get x by itself, combine like terms.

3x° + 180° - 180° = 360° - 180°
3x° = 180°
x = 60°, or B.

1. 72% of the students in Math 6 at AZVA are currently passing mastering their lessons. If 324 students are currently mastering

Alexeev081 [22]

Answer:

1. a. 72/100 = 324/x

72x = 32,400

b. 450 students are in Math 6

2. a. o = 3b

b. o = 3 pounds

3. a. Most popular animals:

A. Dogs - 67%

B. Cats - 20%

C. Other - 8%

D. None - 4%

E. Horses - 1%

b. 20 students

c. If 75 students have cats, the estimate of 250 students isn't correct.

The actual number of students interviewed is 375.

Step-by-step explanation:

1. a. Let's use the following equation to solve the question:

x = Students that are in Math 6

72/100 = 324/x

72 * x = 324 * 100

72x = 32,400

b. Let's solve the equation, as follows:

x = 32,400/72

x = 450

450 students are in Math 6

2. a. The equation is:

o = 0.15 *20b

o = 3b

where, o = weight of oats in pounds and b = number of dog food bags

b. Let's find out the weight of the oats in one dog food bag, using our equation:

o = 0.15 *20b

o = 0.15 *20 * 1

o = 3 pounds

3. a. Most popular animals:

A. Dogs - 67%

B. Cats - 20%

C. Other - 8%

D. None - 4%

E. Horses - 1%

b. If 250 students were interviewed, the 8% who answered "other" are:

8% of 250 = 0.08 * 250 = 20 students

c. If 75 students have cats, the estimate of 250 students isn't correct.

The 20% of 250 is 50, not 75.

0.2 * 250 = 50

The actual number of students interviewed is:

x = Actual number of students interviewed

75/x = 20/100

20x = 7,500

x = 7,500/20

x = 375

The actual number of students interviewed is 375.

Romell receives five points for each correct answer on a

krek1111 [17]

Answer:

5x - 2y = 30

x + y = 35

Step-by-step explanation:

Number of correct answers = x

Number of incorrect answers = y

Points won per correct answer = 5

Points lost per incorrect answer = 2

If Reggie received 30 points :

Required equation :

(points won per correct answer * number of correct answers) + (points lost per incorrect answer * number of incorrect answers)

5x + (-2y) = 30

5x - 2y = 30

Equation showing that Reggie answer all 35 questions :

Number of correct answers + number of incorrect answers = 35

x + y = 35

Please help me! I will mark the correct answer brainliest!

olchik [2.2K]

The answer is 1630 insects.

This is because the increase of insects each week is 50%. This means that by week 11 the amount of insects should be 1630 (when rounded to the nearest whole number.
