If ABF= (7x + 20), FBC=(2x - 5), and ABC= 159", find the value of x. x =
Given :
∠ABF = ( 7x + 20 )°
∠FBC=(2x - 5)°
∠ABC= 159°
To Find :
The value of x .
Solution :
Assuming B the center of a circle .
So , all three given angles must be added to 360° .
[tex](7x+20)+(2x-5)+159=360\\\\9x+15+159=360\\\\x=20.67[/tex]
Therefore , the value of x is 20.67° .
Hence , this is the required solution .

The ' easiest' method here is to substitute k = 1, 2, 3, 4 into the expression and sum the terms, that is
(- 2 + 6(1) ) + ( - 2 + 6(2) ) + ( - 2 + 6(3) ) + (- 2 + 6(4) )
= (- 2 + 6) + (- 2 + 12) + (- 2 + 18) + (- 2 + 24)

Each large cookie is 5/6 oz and each small cookie is 4/9 oz.what is the total weight of 2 large cookies and small cookie? Help asap
Answer:
2 1/9 or 19/9 depends on what answer is required/you want to use
Step-by-step explanation:
First, common denominator
Big cookie = 15/18 oz
Small cookie = 8/18 oz
15*2=30
30+8=38
38/18 = total weight of 2 large and 1 small
2 2/18 mixed fraction
2 1/9 Simplest answer
The total weight of 2 large cookies and small cookie is 2 1/9 oz
Given:
Weight of each large cookie = 5/6 oz
Weight of each small cookie = 4/9 oz
Total weight of 2 large cookies and small cookie = 2(Weight of each large cookie) + Weight of each small cookie
= 2(5/6) + 4/9
= 10/6 + 4/9
= (30+8) / 18
= 38/18
= 2 2/18
= 2 1/9 oz
Therefore, the weight of 2 large cookies and small cookie is 2 1/9 oz

What is the equation of the line passing through the points (–5, –2) and (3, 14) in slope-intercept form?
Answer:
2x-y+2= 0
Step-by-step explanation:
(-5,-2)=(x1, y1)
(3, 14) =(x2, y2)
now,
slope(m)= y2-y1 / x2-x1
=14+2 / 3+5
= 16 /8
=2 units
passing point = (-5,-2) = x1,y1
now,
eqn of the line can be represented as,
y -y1 = m (x-x1)
y +2 = 2 (x +5)
y+2 = 2x +10
y = 2x+10-8
0 = 2x+2-y
2x-y+2 =0 is the required eqn

the length of a rectangle is 3 inches more than it’s width. if the perimeter is 42 inches, find the dimensions of the rectangle
Answer:
length = 12
width = 9
Step-by-step explanation:
We can use a system of linear equations to solve this problem. Lets make the variable L represent length and W represent width.
So we know that the length is 3 more than the width. An equation for this would be:
W = L - 3
We also know that the perimeter is 42 inches. The perimeter of a rectangle, using the variables L and W, is 2L + 2W, or 2(L + W). Using this, we can make the equation:
2(L + W) = 42
We can simplify the last equation by dividing both sides by 2:
L + W = 21
So now we have the two equations:
W = L - 3
L + W = 21
From here, there are multiple ways this question can be solved. I am going to use the substitution method here.
Knowing that W = L - 3, we can replace W in the second equation with L - 3.
L + L - 3 = 21
Add 3 to both sides.
2L = 24
Divide both sides by 2.
L = 12
Now we know that L = 12. Using this, we can replace L with 12 in the first equation to solve for W.
W = 12 - 3
W = 9
So:
L = length = 12
W = width = 9

if mBGC = 16x - 4 and mCGD = 2x + 13, find the value of x so that BGD is a right angle
Hi there! :)
Answer:
[tex]\huge\boxed{x = 4.5}[/tex]
m∠BGC = 16x - 4
m∠CGD = 2x + 13
m∠BGC + m∠CGD sums up to 90°, therefore:
(16x - 4) + (2x + 13) = 90
Combine like terms and simplify:
16x + 2x - 4 + 13 = 90
18x - 4 + 13 = 90
18x + 9 = 90
18x = 81
18x/18 = 81/8
x = 4.5

sum of the numbers m and n decreased by their product; write the algebraic expression
You can write mn as m*n
=================================
Explanation:
The sum is the result of adding two or more numbers. Saying the sum of m and n means m+n.
Then we subtract off the product of m and n. The product is the result of multiplying m and n. We say m*n or mn to indicate their product.
Overall, we end up with m+n-mn
