Answer:
x = 35
Step-by-step explanation:
Sum of angles of triangle = 180°
60 + 60 + 4x - 80 = 180 40 + 4x = 180 4x = 140x = 140/4 x = 35°❒ Required Solution:
We are here to find the three angles with the help of the angle sum property (Sum of the angles of a triangle = 180°). So, using this property we can find all the angles.❍ According to the question :
[tex]\\ \tt \implies \: 60{}^{ \circ} + 60{}^{ \circ} +(4x - 80) {}^{ \circ} = 180{}^{ \circ} \\ \\ \\ \implies \tt \: 120{}^{ \circ} - 80{}^{ \circ} + 4x = 180{}^{ \circ} \: \: \: \: \: \: \\ \\ \\ \implies \tt 40{}^{ \circ} + 4x = 180{}^{ \circ} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \implies \tt \: 4x = 180{}^{ \circ} - 140{}^{ \circ} \: \: \: \: \: \: \\ \\ \\ \tt \implies \: 4x = 140{}^{ \circ} \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \implies \tt \: x = \frac{140}{4} \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \tt \implies \: { \boxed{ \mathfrak{ \pmb{ \pink{x = 35}}}}} \bigstar \\ \\ \\ [/tex]

4 less than n is 9.?
Answers
Answer:
13. Bestie literally 9+4
Answer:When solving a question like "What number is 4 less than 9?", take a close look at what it is really asking.
You have the number 9 and you are looking for a number that is 4 less than 9. In other words, if you have 9 and take away 4, then how many do you have?
You guessed it! This is a subtraction problem. 9 is the minuend and 4 is subtrahend and the answer we are looking for is the difference.
Therefore, to solve "What number is 4 less than 9?", you subtract 4 from 9 like so:
9 - 4 = 5

James fences in his backyard. The perimeter of his fence is 20 feet, and the width of his yard is 2 feet wide. Use the perimeter formula to find the length of his rectangular yard in INCHES: P = 2L + 2W
Answers
Answer:
96 inches
Step-by-step explanation:
Because we already have the perimeter, we have to solve the formula for L (length). To do this, simply subtract 2W (width) from both sides so that we're left with 2L by itself. The formula is now 2L= P-2W. When we plug in the numbers we get 2L= 20'-2(2'). All we have to do is solve for L.
2L= 20'-4'
2L=16'
[tex]\frac{2L}{2}[/tex]=[tex]\frac{16}{2}[/tex]
L=8'
We need the answer to be in inches, so multiply 8(12) to get 96''

Answer:
you would need 12 gallons of water.
Step-by-step explanation:
The ratio is 4 : 1/3. This means that for every 1/3 cups of cleaner, there is 4 gallons of water.
This in mind, 3 1/3 cups of cleaner would be 1/3 x 3.
Whatever you do to one side, you have to do to the other.
4 gallons x 3 = 12.

Can anybody help find the line of reflection??
Answers
I'll do part (a) to get you started. Part (b) will follow the same sort of steps.
In part (a), we have these two points
A = (-3,2)B = (3,8)You can call the points any letters you want. Let's find the slope of line AB
m = (y2-y1)/(x2-x1)
m = (8-2)/(3-(-3))
m = (8-2)/(3+3)
m = 6/6
m = 1
The slope of line AB is 1.
The mirror line will have the negative reciprocal of this slope, so the slope of the mirror line is -1. In other words, the mirror line slope is perpendicular to line AB. We'll use this perpendicular slope later.
-------------------------------------------
Next, we find the midpoint of segment AB
Average the x coordinates to get (x1+x2)/2 = (-3+3)/2 = 0/2 = 0
Repeat for the y coordinates: (y1+y2)/2 = (2+8)/2 = 10/2 = 5
The midpoint of AB is (0,5)
-------------------------------------------
The mirror line will have two defining traits
The slope of the mirror line is m = -1The mirror line goes through the midpoint (x,y) = (0,5)So,
y = mx+b
y = -1x+b ... plugging in that perpendicular slope
5 = -1*0+b .... plugging in (x,y) = (0,5)
5 = 0+b
b = 5
The equation of the mirror line is y = -x+5 as shown in the diagram below. The mirror line is shown in green. Point D isn't important as it's just used to help set up the 90 degree angle.
This wraps up part (a) and I'll let you handle part (b). If you're stuck, then feel free to ask.

Step-by-step explanation:
When both integers are negative, you can treat them the same as positive numbers and add a negative sign to your final sum.
1+2 2/5 (or 2 4/10 or 2.4) is equal to 3 2/5. So (-1)+ (-2 2/5) is equal to -3 2/5, or -3.4.
