<h2>Fractions</h2>

Which expression is equal to \large\tt \frac{4}{8}?

Option 1

  • \large \tt 4  \times \frac{1}{2}  =  \frac{4}{1}  \times  \frac{1}{2}  =   \red{\frac{4}{2}}

Option 1 is not equal to \large\tt \frac{4}{8}

Option 2

  • \large \tt 3 \times  \frac{1}{5}  =  \frac{3}{1}  \times  \frac{1}{5}  =   \red{\frac{3}{5}}

Option 2 is not equal to \large\tt \frac{4}{8}

Option 3

  • \large \tt 3  \times \frac{1}{8}  =  \frac{3}{1} \times  \frac{1}{8}   =   \red{\frac{3}{8}}

Option 3 is not equal to \large\tt \frac{4}{8}

Option 4

  • \large \tt 4  \times \frac{1}{8}  =   \frac{4}{1}  \times  \frac{1}{8}  =   \green{\frac{4}{8}}

Therefore, option 4 is equal to \large\tt \frac{4}{8}

One angle of a triangle has a measure of 36°. The measure of the third angle is 28° less than 3 times the measure of the second
Alex_Xolod [135]

Answer:

  1. Define your variable and write your equation:  36 + b + (3b-28) = 180°.
  2. measure of the second angle: 43°.
  3. measure of the third angle: 101°

Step-by-step explanation:

a = 36

c = 3b - 28

a + b + c = 180°

a = measure of the first angle

b = measure of the second angle

c = measure of the third angle

then:

1)  36 + b + (3b-28) = 180   ⇒ )Define your variable. Write your equation and solve)

b + 3b + 36 - 28 = 180

4b + 8 = 180

4b = 180 - 8

4b = 172

b = 172/4

2)   b = 43°        ⇒   measure of the second angle

c = 3b - 28

c = 3*43 - 28

c = 129 - 28

3) c = 101°      ⇒   measure of the third angle

Check:

36° + 43° + 101° = 180°

Answer:

M=7/8

Step-by-step explanation:

The equation used to solve this is yz-y1/x2-x1.

This applied to the problem would look like 9-2/3--5

Simplified this would be, 7/8 as your slope

Are all triangles similar
laila [671]
No. There are 3 types of triangles.

Scalene: Triangle which no sides are equal, so all angles aren't congruent

Isosceles: A triangle with 2 equals sides, but has 1 not equal sides.

Equilateral: A triangle which all sides are equal
