so 2 solutions :

4x-3= 0

4x=3

x = 3/4

and x+2 = 0.

x= -2

solutions are : -2 +and 3/4

--The sum of two numbers is 33. One number is 2 times as large as the other. What are the numbers?​
frozen [14]

Answer:

11 and 22

Step-by-step explanation:

Let x be the first number

the second number is twice the first one so it's 2x

The equation is

  • 2x+x =33
  • 3x = 33             divide by 3 in each side
  • x = 33/3
  • x= 11

so the first number is 11 and the second one 22 (11*2)

Pleaseeeeeeeee helpppp...
zvonat [6]

Answer:

x = 67

Step-by-step explanation:

∠ CRQ = ∠ BQR = 113° ( Alternate angles )

∠ CRQ and ∠ CRS are adjacent angles and supplementary, that is

x + 113 = 180 ( subtract 113 from both sides )

x = 67

Is 2.4, 4.5 and 5.2 a right triangle?
grandymaker [24]

Answer:

No

Step-by-step explanation:

Use the pythagorian theorm to find whether it's a right triangle or not.

So the hyp will be the largest number. And the hyp must be equal to the sum of b and c squared

5.2 squared= 2.4 squared+ 4m5 squared

27.04= 26.01

It's not equal so the triangle isn't a right triangle.

Answer:

30.5 ; 49 ; 27 ; 50 ; 45

Step-by-step explanation:

Determine the first and third quartiles. Determine the second decile and the eighth decile. Determine the 67th percentile

Given the ordered data :

13 13 13 20 26 27 29 32 34 34 35 35 36 37 38 41 41 41 42 44 46 47 48 50 53 55 56 62 67 82

Sample size, n = 30

The first quartile ;Q1

Q1 = 1/4(n+1)th term

Q1 = 31/4 = 7.75th term

Q1 = (29+32)/2

Q1 = 30.5

Q3 ;

Q3 = 3/4(n+1)th term

Q3 = 3(31)/4 = 23.25 th term

Q3 = (48 + 50) /2 = 49

2nd decile :

0.2 * (nth term

0.2 * 30 = 6th term = 27

8th decile :

0.8 * 30 = 24 th term

= 50

67th percentile :

0.67 * (n+1)th term

0.67 * 31 = 20.77

= (44 + 46) / 2

= 45
