Simplify this please 2 7/8 - 4 3/8

Mathematics
1 answer:
nalin [4]3 years ago
4 0

Answer:

The answer is -1 1/2

Step-by-step explanation:

This problem doesn't have that much steps.

What you do is this.

Step 1: You have 2 7/8 and 4 3/8 now turn it into a improper faction it will look like this 23/8 -35/8

Step 2: Now minus 23/8 and 35/8 23-35= -12 and the 8's stay the same now it will look like this -12/8

Step 3: Now see how many times 8 can go into -12 so -8 times 1= -8 now get from -8 to -12 that equals 4 so it will look like this -1 4/8 that can be simplify by 4 because 4x1=4 And 4x2=8 Now your answer is -1 /12

A rectangle patio that originally measured 5 feet by 10 feet was extended on one side each by x feet. The area of a new, larger,
Neporo4naja [7]
We solve for the area of the original triangle and solution is shown below:
Original triangle area = LW = 5*10 = 20 squared units

If we extend this x on one side that resulted to L-shaped, we have the new area such as shown below:
New area = (L+X) (W)
126 = (5+x) * 10
126/10 = 5+x
12.6 - 5 = x
7.6 =x

I. The equation that could be used to solve for x is below:
126 = (5+x)*w
II. We arrived on this because of the statement that "x is added to one side that resulted to L-shaped rectangle, therefore it is added on 5 ft side"
III. The value of x is equal to 7.6 ft.

So I have this question I cannot figure out 3w+w2+1=10−w
Mandarinka [93]

Answer:

<u>Answer</u><u>:</u><u> </u><u>w</u><u> </u><u>is</u><u> </u><u>1</u><u>.</u><u>6</u><u> </u><u> </u><u>or</u><u>. </u><u>-</u><u>5</u><u>.</u><u>6</u><u> </u>

Step-by-step explanation:

• I guess the question asks to find the value of w

{ \rm{3w +  {w}^{2} + 1 = 10 - w }}

• arrange the equation in a quadratic equation format. i.e; ax² + bx + c = 0

{ \rm{ {w}^{2} + (3w + w) + 1 - 10 = 0 }} \\  \\ { \rm{ {w}^{2} + 4w - 9 = 0 }}

• let's solve the equation using the quadratic formular

\hookrightarrow \: { \tt{w =  \frac{ - b \pm \sqrt{ {b}^{2}  - 4ac} }{2a} }} \\

  • a is 1
  • b is 4
  • c is -9

• Substitute following the mathematical operation rules:

{ \rm{w =  \frac{ - 4 \pm \sqrt{ {4}^{2} - (4 \times 1 \times  - 9) } }{(2 \times 1)} }} \\  \\ { \rm{w =  \frac{ - 4 \pm \sqrt{52} }{2} }}

• split the result:

{ \rm{either \:  \{w =  \frac{ - 4 +  \sqrt{52} }{2} \} \:  \: or \:  \:  \{w =  \frac{ - 4 -  \sqrt{52} }{2}  \} }} \\  \\ { \rm{either \:  \{w = 1.6 \} \:  \: or \:  \:  \{w =  - 5.6 \}}}
