Answer:

  x = (ab +a +b +c)/(a +b)

Step-by-step explanation:

Eliminate parentheses, subtract left terms not containing x, divide by the coefficient of x.

  [tex]a(x-b)+bx-c=a+b\\\\ax+bx-ab-c=a+b\\\\x(a+b)=ab+a+b+c\\\\\boxed{x=\dfrac{ab+a+b+c}{a+b}}[/tex]

Answer:

Value for X = 7

Explanation:

Given:

FE parallel to BC

Find:

Value for X

Computation:

EA / CE = FA / BF

So,

18 / 10 = (X+20) / (X+8)

18X + 144 = 10X + 200

8X = 56

X = 56/8

X = 7

Value for X = 7

Answer:

Lateral surface area= 48cm^2

Step-by-step explanation:

for anyone who needs the lateral surface area.

The total surface area of the square pyramid with a base side length of 6 cm and a slant height of 4 cm is 84 square centimeters.

We have,

Base side length (s) = 6 cm

Slant height (l) = 4 cm

Area of square = s²

Area of base = 6² = 36 cm²

A square pyramid has four triangular lateral faces with equal area.

The formula for the area of a triangle.

Area of triangle = 1/2 * base * height

Area of lateral surface of the triangle = 1/2 * 6 cm * 4 cm = 12 cm²

Total lateral area = 4 * 12 cm² = 48 cm²

Total surface area = Area of base + Total lateral area

Total surface area = 36 cm² + 48 cm²

Total surface area = 84 cm²

Therefore,

The total surface area of the square pyramid with a base side length of 6 cm and a slant height of 4 cm is 84 square centimeters.

Answer:

x = 0

Step-by-step explanation:

We can find slope using this formula:

[tex]\frac{y2 - y1}{x2 - x1} = slope[/tex]

So we plug it in like this:

[tex]\frac{-5 - -2}{0-0} = \frac{-3}{0} \\[/tex]

We see that the slope is undefined so it will be a straight vertical line

So in order to pass through y = -5 and y = -2, x would have to equal 0.

Therefore, the equation is x = 0

Hope this helps!!

Step-by-step explanation:

let length of the pool be l feet and width be w feet.

l = 2w + 1 --(1)

2(l + w) = 74 --(2)

sub (1) into (2):

2(2w + 1 + w) = 74

6w = 72

w = 12

therefore, length is 25feet and width is 12feet

Answer:

75/100

Step-by-step explanation:

Answer: He will miss 57 out of 200 shots

so the answer is 200-57=

**143**

Step-by-step explanation:  The REAL ratio is 2:7 (2 out of 7 shots will miss ---- referring to the hint given)

Solution:

Since

2 : 7 = X : 200

Then we know

2/7 = X/200

Multiplying both sides by 200 cancels on the right

200 × (2/7) = (X/200) × 200

200 × (2/7) = X

Then solving for X

X = 200 × (2/7)

X = 57.142857142857

Therefore

2 : 7 = 57.142857142857 : 200

Answer:

Slope = 1

Step-by-step explanation:

Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]

Given points: (-2, 1), (3, 6)

(-2, 1) = (x1, y1)

(3, 6) = (x2, y2)

When two lines are parallel, their slopes are equal. So to find the slope of a line parallel to line A, all we need to do is find the slope of line A. To do this, input the given points into the formula used to find slope:

[tex]\frac{6-1}{3-(-2)}[/tex]

Simplify:

6 - 1 = 5

3 - (-2) = 3 + 2 = 5

[tex]\frac{5}{5}=1[/tex]

The slope of line A and the line parallel to it is 1.

Answer:

14 eggs

Step-by-step explanation:

Answer: It takes 14 eggs to make 42 dozen cookies

Step-by-step explanation: To solve using a proportion first start out with 2eggs/6cookies (They are in a dozen but 42 is also in a dozen so it cancels out). Now that you have 2/6 you now have to find the x in x/42. 42 divided by 6 is 7 so multiply 2 by 7 and you get: It takes 14 eggs to make 42 dozen cookies or 14/42. Hope this helps

Step-by-step explanation:

Answer:

Step-by-step explanation:

16). m∠1 = m∠2 = m∠3 = m∠4 = 74°

m∠5 = m∠6 = m∠7 = m∠8 = 180° - 74° = 106°

17). m∠2 = m∠5 = m∠15 = 125°

m∠1 = m∠6 = m∠10 = m∠16 = 180° - 125° = 55°

m∠11 = 125° - m∠12 = 125° - 37° = 88°

m∠3 = m∠9 = m∠13 = m∠18 = 102°

m∠4 = m∠14 = m∠17 = 180° - 102° = 78°

m∠8 = 180° - (m∠12 + m∠13) = 180° - (102° + 37°) = 41°

m∠7 = m∠14 - m∠8 =  78° - 41° = 37°
