Answer 1
Alright let’s use the variable X here for example.

2(X - 4) = 3
And that missing number is 5 1/2.
Which now equals 3.

Find three consecutive natural numbers such that the sum of the first and the second is 15 more than the third

Answers

Answer: 16, 17 and 18

Step-by-step explanation:

Let the consecutive natural numbers be x, x+1, and x+2. We are informed that the sum of the first and the second is 15 more than the third. This will be:

[x + x + 1] = [x + 2] + 15

2x + 1 = x + 2 + 15

2x + 1 = x + 17

2x - x = 17 - 1

x = 16

The numbers are 16, 17 and 18.

The crowd at a concert estimated to be 3,500 people. The exact attendance is 3,486 people. What is the percent error?

Answers

Answer:

0.4016%

Step-by-step explanation:

Estimated Value = 3,500 people ,  Exact attendance = 3486 people

We can see that there is a Percentage decrease . So we will apply the formula.

%Decrease = Old Value - New Value /Old Value × 100%

%decrease = 14/3486 %

%Decrease = 0.4016% (Answer)

find the value of x..

Answers

Answer:

B x = 7

Step-by-step explanation:

You know based on the ratio that it's being scaled by 4 times because the one side 4 is 16 in the bigger pentagon.

So if you go the side that matches the one you need to solve, it's 2.5.

2.5 times 4 = 10 so that bigger pentagon side should equal 10.

The equation x-3 = 10

which means x is 7

What is the area of the football field in the scale drawing? Assume that the field is shaped like a rectangle.

Answers

Answer:

i mean might as well get free points now that its 2 weeks old

Step-by-step explanation:

Answer:

Pythagorean Theorem: the diagonal of the football field is the hypotenuse. Let´s say the diagonal is C and the two other sides are A and B.

Width = A

Length = B

Diagonal = C

so: a2+b2=c

2502+1002=c2

2500+10000=c2

12500=c2

c=√12500

c=111.80 yards

X, Y and Z are three points on a map. Y is 75km and on a bearing of 200° from X. Z is on a bearing of 150°, from Y. Z is due south of X. Calculate the distance between X and Z rounded to 1 DP.

Answers

Answer:

The distance between X and Z is approximately 114.9 km

Step-by-step explanation:

The given parameters are;

The distance of Y from X = 75 km

The bearing of Y from X = 200°

The bearing of Z from Y = 150°

The bearing of Z from X = 180°

In triangle XYZ, we have;

∠YZX = 180° - (130° + 20°) = 30°

By sine rule, we have;

(75 km)/sin(30°) = XZ/(sin(130°))

XZ = sin(130°) × (75 km)/sin(30°) ≈ 114.9 km

The distance between X and Z ≈ 114.9 km. to one decimal place.

Solve the following:
a) 2(5x – 3) = 24
b) 5(2x + 1) = 50​

Answers

Answer:

x = 3 and x = [tex]\frac{9}{2}[/tex]

Step-by-step explanation:

(a)

2(5x - 3) = 24 ( divide both sides by 2 )

5x - 3 = 12 ( add 3 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3

(b)

5(2x + 1) = 50 ( divide both sides by 5 )

2x + 1 = 10 ( subtract 1 from both sides )

2x = 9 ( divide both sides by 2 )

x = [tex]\frac{9}{2}[/tex]
