Helga [31]3 years ago

Answer:

If the sum of a triangle equals 180 degrees we’ll go off of that by doing this.

(7x+8)+(5x+2)+(7x-1)=180
7x+8+5x+2+7x-1=180
19x+9=180
19x=180-9
19x=171
19x/19=171/19
x=9

With that let’s find each angle,

I’ll just label them A, B, C.

A: (7x+8)
7(9)+8
63+8=71

B: (7x-1)
7(9)-1
63-1=62

C: (5x+2)
5(9)+2
45+2=47

71+62+47=180

solniwko [45]

Answer:

Step-by-step explanation:

m=p/3

t=(3/10)(1-1/3)

t=(3/10)(2/3)=p/5

p-p/3-p/5=35

(15p-5p-3p)/15=35

7p=525

p=75

olya-2409 [2.1K]

Answer:

x = \{13,14\}

Step-by-step explanation:

Given

x + 2x + 6 < 50

Required

True values of x

We have:

x + 2x + 6 < 50\\

3x + 6 < 50

Collect like terms

3x < 50-6

3x < 44

Divide both sides by 3

x < 44/3

x < 14.67

This means that x has a value lesser than 14.67.

Hence, the valid values are:

x = \{13,14\}
