Solve
1. 3x(4-9)+7x-5=303
2. 5(2x+3)+12x=17
3. 7(4x-4)-20=38

Answers

Answer 1

1. 12x - 27x + 7x - 5 = 303

- 15x + 7x - 5 = 303

- 8x = 303 + 5

-8x = 308

x = - 38.5

2. 10x + 15 + 12x = 17

22x + 15 = 17

22x = 17 - 15

22x = 2

x = 0.0909090909

3.28x - 28 - 20 = 38

28x - 48 = 38

28x = 38 + 48

28x = 86

x = 3.07

x=10, y=20

Step-by-step explanation:

180-20-=160

160-90=7x

7x=70

x=10

5x+2y=90

5(10)+2y=90

50+2y=90

2y=40

y=20

Hope this helps! :)

Answer:

x=10     y= 20

Step-by-step explanation:

to find x use the 20* and the 90* from the top to get 110

then use the straight  line to subtract 110     180-110=70  

then do 70 / 7 =10

to find y solve for 5x first to get 50 add 70* from the vertical angle to get 120

then use the vertical angle from 20* to get 140

then use the straight line to subtract  140          180-140=40

then do 40/2 = 20

1) x = 20

2) Try it yourself based on #1

3) D. BE (it a a segment, it is on the hypotenuse, and it is adjacent to AB)

Step-by-step explanation:

I'll do the first one and you can try the second one

1) Since the two triangles are similar, corresponding parts are similar (CPSP - corresponding parts of similar polygons)

2) Since the corresponding sides are similar, [tex]\frac{AX}{AB} = \frac{XY}{BC}[/tex]

3) We know that AX is 12, AB is 20 (AX+XB=12+8 because of pwp -> part whole postulate), XY is 17, and BC is x

4) Substitute these values into the equation from step 2

[tex]\frac{12}{20} = \frac{12}{x}[/tex]

5) Cross-multiply to get 12x = 12(20)

6) Solve

12x = 240

The value of x is 3 in the triangle.

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

By pythagoras theorem we find the value of x.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides

x²+x²=(3√2)²

2x²=9×2

2x²=18

Divide both sides by 2

x²=9

Take square root on both sides

x=3

Hence, the value of x is 3 in the triangle.
