The two angles form a right triangle which is 90 degrees.
Add the two to equal 90:
3x-8 + 4x = 90
simplify:
7x-8 = 90
Add 8 to both sides:
7x = 98
Divide both sides by 7:
x = 14

Answer:
111.46 units
Step-by-step explanation:
The right triangle has side lengths that are 1/√2 times the hypotenuse length, so each is (18√2)/(√2) = 18 units. The top is this length shorter than the bottom, so the total of all side lengths (CW from left) is ...
18 + (43 -18) +18√2 +43 = 86 +18√2 ≈ 111.46 units

Four families went out for lunch. The total food
bill came to $167. The families also left a $30 tip for the
waitress. If each family spent the same amount, about how
much did each family spend on dinner? Explain how you
found your answer.
Answers
Answer:
Each family spent about 34.25 on dinner
Step-by-step explanation:
$167 - $30 (tip) = 137
137 ÷ 4 (for each family) = 34.25
BUT
if each family is seperate than they each spent about 11.75 on dinner
167 - (30 x 4) = 47
47 ÷ 4 = 11.75
I'm pretty sure the first one is the answer though
If the total includes the tip, each family spent $34.25 on their food bill and $7.50 on the tip for the waitress.
If the total doesn't include the tip, but you want to include the tip, each family spent $49.25 on the food bill AND tip.
167/4 = 41.25
(167-30)/4 = 34.25
30/4 = 7.50
(167+30)/4 = 49.25

See attachment for further explanation
Hope this helps (:
The slope of the line that passes through (2, 3)(5, 9) is 2
Slope formula is describe below:m = y₂ - y₁ / x₂ - x₁Therefore, the slope of the line that passes through the points (2, 3)(5, 9) can be found as follows;
y₁ = 3
y₂ = 9
x₁ = 2
x₂ = 5
m = 9 - 3 / 5 - 2
m = 6 / 3
m = 2
slope = 2
Therefore, the slope of the line that passes through (2, 3)(5, 9) is 2

Farmer Brown has 360 feet of fencing to use to construct a rectangular enclosure for his prized goats. Which equation gives an area A as a function of the width w of the enclosure?
A(w)=180−w2
A(w)=360−w2
A(w)=180w−w2
A(w)=360w−2w2
Answers
Answer:
A(w) = 180w-w²
Step-by-step explanation:
Farmer Brown has 360 feet of fencing to use to construct a rectangular enclosure for his prized goats.
It means that the perimeter of the rectangle is 360 feet
The formula for the perimeter of a rectangular shape is given by :
P = 2(l+w)
l is length and w is width
ATQ,
2(l+w) = 360
(l+w) =180
l = 180 -w .....(1)
The formula for the area of a rectangle is given by :
A = lw
Put the value of l form equation (1).
A = (180-w)w
A(w) = 180w-w²
Hence, the correct option is (c).
Determine the number and types of solutions for

To find:
The number and types of solutions for the given equation.
Solution:
We have,
[tex]6m^2-3m-4=0[/tex]
It is a 2nd degree polynomial because the highest degree of the variable x is 2.
Number of solutions = Degree of the polynomial
Number of solutions = 2
Therefore, the given equation has 2 solutions.
In a quadratic equation [tex]ax^2+bx+c=0[/tex], if [tex]b^2-4ac>0[/tex], then the equation has two distinct real solutions.
For the given equation, a=6, b=-3 and c=-4.
[tex]D=b^2-4ac[/tex]
[tex]D=(-3)^2-4(6)(-4)[/tex]
[tex]D=9+96[/tex]
[tex]D=105>0[/tex]
Therefore, the given equation has two distinct real solutions.
Use the associative property of addition to write an equivalent expression for (x+17) + y
An equivalent expression is
Answers
Answer:
x + (y + 17)
Step-by-step explanation:
The associative property of addition is characterized by altering the order of operations by putting brackets in a different place. The answer will always be the same. Just the order is different.
So one possibility and the one you are likely expected to give is
x + (y + 17)
That means that if 17 and y can be added by giving y a value, then they will be done first.
Then you add z to the result if it has been given a value.
The answer you are expected to give is x + (y + 17)
