#1: Find the value of X. (GEOMETRY)

Mathematics
1 answer:
grandymaker [24]2 years ago
3 0

Answer:

x = 14

Step-by-step explanation:

1. We know that all angle measures in a triangle sum to 180 degrees.

  • This means that 7x - 11 + 5x - 2 + 2x - 3 = 180.

2. (Solving)

Step 1: Combine like terms.

  • (7x+5x+2x)+(-11-2-3)=180
  • 14x -16 = 180

Step 2: Add 16 to both sides.

  • 14x - 16 + 16 = 180 + 16
  • 14x = 196

Step 3: Divide both sides by 14.

  • \frac{14x}{14}=\frac{196}{14}
  • x = 14

Step 2: Check if solution is correct.

  • 7(14)-11+5(14)-2+2(14)-3=180
  • 98-11+70-2+28-3=180
  • 180=180

Therefore, the answer is x = 14.

Y = 5- 2<br> 1-3x + y = -12<br><br> What is the value of x and y ?
zloy xaker [14]

Answer:

x=5.333

y=3

Step-by-step explanation:

given, y=5-2............(1)

1-3x+y=-12...............(2)

y=5-2=3

put y=3 in equ (2)

1-3x+3=-12

1+3+12=3x

3x=16

x=\frac{16}{3}

x=5.333

hence, x=5.333

⚠️⚠️Please help⚠️⚠️ Pip and Ali share S785 in the ratio Pip:Ali = 4:1.<br><br> Work out Pip's share.
oksano4ka [1.4K]
<h3>Answer:   $628 </h3>

==========================================================

Work Shown:

x = Ali's share

4x = Pip's share, because it is four times bigger due to the ratio 4:1

x+4x = 5x = total amount of money = 785

5x = 785

x = 785/5

x = 157 dollars is Ali's share

4x = 4*157 = 628 dollars is Pip's share

Note that 157+628 = 785 to help confirm the answer.

“Write an equation in slope-intercept form for the line with slope 3/2 and y-intercept -7.”
gregori [183]

Answer:

y = 3/2x - 7

Step-by-step explanation:

slope-intercept: y = mx + b

m = slope (3/2)

b = y-intercept (-7)

when put together, the equation is y = 3/2x - 7.
