Find the error in the problem below

Mathematics
1 answer:
qaws [65]3 years ago
7 0

Answer:

You aren't supposed to add 3k

Step-by-step explanation:

3k is a positve number. So instead of adding you have to subtract to be able to move on. Correct way shown below. Once you get this step wrong your answer will also be wrong. At the end you also need to divide

19-2k= 3k-1

  -3k  -3k

19-5k= -1

-19      -19

 -5k= -20

-5/-5= -20/-5

    k=4

Find the area of the shapes
Dmitry [639]

Answer:

1. 800 cm squared

2. 152 cm squared

Step-by-step explanation:

let break it down

1. 800 cm squared

20 * 7 = 140

20 * 6 = 120

38 - 20 = 18

30 * 18 = 540

now add all of them together

140 + 120 + 540

100 + 100 + 500 = 700

40 + 20 + 40 = 100

700 + 100 = 800 cm squared

2. 152 cm squared

16 * 10 = 160

2 * 2 + 2 * 2 = 4 + 4 = 8

160 - 8 = 152 cm squared

What is the value of x?​
adell [148]

again, we're assuming that both triangles are similar, and thus using proportions.

\stackrel{\textit{assuming the triangles are similar}}{\cfrac{x+1}{27}=\cfrac{5}{x-5}\implies x^2+x-5x-5=135}\implies x^2-4x-5=135 \\\\\\ x^2-4x-140=0\implies (x-14)(x+10)=0\implies x = \begin{cases} 14~\textit{\large \checkmark}\\ -10 \end{cases}

we do not use the -10, because whatever value "x" may be, can't be negative or even 0.

Arelli is 12 5 6 years old. Carl is 1 1 3 years younger than Arelli and Jane is 1 1 4 years younger than Carl. How old is Jane?
Montano1993 [528]

Answer:

10 1/4

Step-by-step explanation:

Carls age = 12 5/6 - 1 1/3

12 5/6 - 1 1/3

11 (5 - 2) / 6 = 11 3/6

Jane's age = carl's age - 1 1/4

11 3/6 - 1 1/4

10 (12 - 6) / 24 = 10 6/24 = 10 1/4
