Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°, thus

6x + 1 + 9x - 24 + 5x - 17 = 180, that is

20x - 40 = 180 ( add 40 to both sides )

20x = 220 ( divide both sides by 20 )

x = 11

Hence

∠PTA = 9x - 24 = (9 × 11) - 24 = 99 - 24 = 75°

∠APT = 6x + 1 = (6 × 11) + 1 = 66 + 1 = 67°

∠PAT = 5x - 17 = (5 × 11) - 17 = 55 - 17 = 38°

Answer:

x = 11 ,

<APT = 6x + 1 ➡ 67°

<PTA = 9x - 24 ➡75°

<PAT = 5x - 17 ➡ 38°

Step-by-step explanation:

(5x - 17) + (9x - 24) + (6x + 1)=180°

20x - 40 = 180°

20x = 180° + 40°

20x = 220°

x = 11

A restaurant with two locations buys twelve bags of flour and eight large bags of sugar. Location A receives seven bags of flour
Alborosie
You want to solve this set of linear equations by the elimination method.

Let x=price of bag of flour and y=price of bag of sugar

Multiply the first equation by -3.

-3(7x+5y=584)
Multiply the second equation by 5.
5(5x+3y=384)

Solve by elimination.

X=42

Substitute value of x into one of the original equations.

Y=58

HELP?! PLEASE! Which point is a reflection of7(-6.5,1) across the x-axis and y-axis?
Mandarinka [93]

Answer:

Dont need to worry

First, start off with the x-axis. -6.5, 1 becomes 6.5, 1. This is because point T is 6.5 to the left of the x-axis line, so our new point would be 6.5 to the right of the x-axis line. Same thing for the y-axis, (6.5, 1) would become (6.5, -1).

(5,1); m=2 write an equation of the line
gtnhenbr [62]
Hey there! :) 

To find an equation of a line that passes through (5, 1) and has a slope of 2, we'll need to plug our known variables into the slope-intercept equation.

Slope-intercept equation : y = mx + b ; where m=slope, b=y-intercept

Since we're already given the slope, all we really need to do is find the y-intercept.

We can do this by plugging our known values into the slope-intercept equation.

y = mx + b

Since we're trying to find "b," we need to plug in "y, m, x" into our formula.

(1) = (2)(5) + b

Simplify.

1 = 10 + b

Subtract 10 from both sides.

1 - 10 = b

Simplify.

-9 = b

So, our y-intercept is 9! 

Now, we can very simply plug our known values into slope-intercept form.

y = mx + b

y = 2x - 9 → final answer

~Hope I helped!~

Hat is the solution to the equation 3/3(4c + 16)=2c+9 ?<br><br> c =
marusya05 [52]
If it is \frac{3}{3(4c+16)}=2c+9, go to AAAAAA
if it is (\frac{3}{3})(4c+16)=2c+9, go to BBBBB

AAAAAAAAA
\frac{3}{3(4c+16)}=2c+9
\frac{1}{4c+16}=2c+9
times 4c+16 to both sides
1=(2c+9)(4c+16)
distribute
1=8c^2+68c+144
minus 1 both sides
0=8c^2+68c+143
use quadratic formula
c=\frac{-17- \sqrt{3} }{4} or \frac{-17+ \sqrt{3} }{4}




BBBBBBBBBBBB
(3/3)(4c+16)=2c+9
1(4c+16)=2c+9
4c+16=2c+9
minus 2c both sides
2c+16=9
minus 16 both sides
2c=-7
divide both sides by 2
c=-7/2
c=-3.5





if it is \frac{3}{3(4c+16)}=2c+9,
c=\frac{-17- \sqrt{3} }{4} or \frac{-17+ \sqrt{3} }{4}


if it is (\frac{3}{3})(4c+16)=2c+9, c=-3.5
