what is the value of x that makes the equation true.
please help!​

Answer:

7

Step-by-step explanation:

The number of sheep in the petting zoo will be 7.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the petting zoo at the park has 61 ducks and sheep, combined. The animals have a total of 150 legs.

The number of sheep will be calculated by forming the linear equation for the total number of legs,

61 x 2 + 4s = 150

4s = 150 - 122

4s = 28

s = 7

The number of sheep will be 7.

Answer:

$72

Step-by-step explanation:

$768/265 = $3

$3 x 24 = $72

Answer:

$72

Step-by-step explanation:

768/256 = how much each hot dog was sold for

768/256 = 3

Each hot dog was sold for $3.

24*3 = $72

Therefore, the cost of 24 hot dogs is $72.

Answer:

m = 12.728 or 18/root (2)/2, n = 9

Step-by-step explanation:

To find m, we can use sin(45) and cos(45).

Since sin(45) = root (2)/2  and this equals 9/m.

We set the equation root (2)/2  = 9/m and solve for m.

9 divided by root (2)/2 would give us 18/root (2), or 12.728.

m is 12.728.

Same process for n but we are using cosine this time.

cos(45) = root (2)/2 and this equals n/12.728.

Solving for n would give us root (2)/2 times 12.728.

This gives us that n is 9.

We are Given:_______________________________________________

ΔABC right angled at B

BC = 8

AC = 20

Part A:_____________________________________________________

Finding the length of AB

From the Pythagoras theorem, we know that:

AC² = BC² + AB²

replacing the given values

(20)² = (8)² + AB²

400 = 64 + AB²

AB² = 336                  [subtracting 64 from both sides]

AB = 18.3                   [taking the square root of both sides]

Part B:_____________________________________________________

Finding Sin(A)

we know that Sin(θ) = Opposite / Hypotenuse

The side opposite to ∠A is BC and The hypotenuse is AC

So, Sin(A) = BC / AC

Sin(A) = 8/20                      [plugging the values]

Sin(A) = 2/5

Part C:_____________________________________________________

Finding Cos(A)

We know that Cos(θ) = Adjacent / Hypotenuse

The Side adjacent to ∠A is AB and the hypotenuse is AC

So, Cos(A) = AB / AC

Cos(A) = 18.3/20                    [plugging the values]

Cos(A) = 183 / 200

Part D:_____________________________________________________

Finding Tan(A)

We know that Tan(θ) = Opposite / Adjacent

Since BC is opposite and AB is adjacent to ∠A

Tan(A) = BC / AB

Tan(A) = 8 / 18.3                  [plugging the values]

Tan(A) = 80 / 183

Answer:

by using Pythagoras law

ac²=ab²+bc²

20²=ab²+8²

ab²=20²-8²

AB=√336=18.33

Step-by-step explanation:

sin a=p/h=8/20=2/5

cos a =b/h=18.33/20

tana =p/b=8/18.33

Answer:

8x + 12

Step-by-step explanation:

1.) 4(2x + 3)

2.) 8x + 12

You just distribute it out. When you have 8x + 12 the only other thing you could do is factor it to get back to 4(2x + 3)! Hope this helps!

Answer:

8x + 12

Step-by-step explanation:

4 × 2x = 8x

4×3 = 12

8x +12

Step-by-step explanation:

Given Function

f(x) = 2.5x + 150

f^-1(x) = ?

Let y = f(x)

y = 2.5x + 150

Interchanging the role of x and y we get,

x = 2.5y + 150

x - 150 = 2.5y

y = (x - 150) / 2.5

So therefore

f^ -1(x) = (x - 150) / 2.5

Answer:

8 is the length of JB

Step-by-step explanation:

Key skills needed: Equations, Congruence

1) We need to find out an equation to make based on the lengths that are given. ΔJMB is congruent to ΔKMB because of Side-Angle-Side:

2) Now since both triangles are congruent, we can make the equation that the length of JM is congruent to the length of MK, using the fact that: If triangles are congruent, then corresponding parts are congruent.

3) This means that 16x -24 = 4x

Subtract 16x from both sides : -24 = -12x

Divide by -12 on both sides and get x = 2

4) Substitute x into the length of JB (16x-24)

16(2)-24 = 32-24 = 8

5) Therefore, the length of JB is 8

Answer:

X = 56 degrees

Step-by-step explanation:

Angles D and F are equivalent. Because the three angles must add up to 180 degrees, you must add 112 to 68 in order to reach 180. Then you must divide this in half, getting 56 degrees as your answer.

180 - 68 = 112

112/2 = 56

X=56

Answer:

y = (1/3)x

Step-by-step explanation:

1) Use the slope formula: (y2-y1)/(x2-x1) and then substitute both points into the formula. That should give you (2-0)/(6-0) = 2/6 = 1/3.

1/3 would then be your slope

2) Since the y intercept is (0,0), the y-intercept isn't needed in the slope intercept equation

So that would give you y = (1/3)x
