Regroup 5 4/6

5 4/6 = (5*6 + 4) / 6 = (30 + 4) / 6

= 34/6

So we have regrouped it as 34/6 which is also an improper fraction.

Hope this helps.

6 1/2 + 1 3/5 + 4 3/4

taurus [48]

Answer:

The answer for this question would be 85 and 17/20 or /20

Step-by-step explanation:

You must first find the LCD of these terms (everything that is separated by the addition signs).

The LCD is 20 because:

2 x 10 = 20

5 x 4 = 20

4 x 5=20

and there is no number lower than 20 that all of these numbers share in their multiplication table.

Now you must multiply every term by the number you used to make its denominator 20. Since 2 x 10 = 20, the new term would be:

60 10/20

Since 5 x 4 = 20, the new term would be:

4 12/20

Since 4 x 5 = 20, the new term would be:

20 15/20

Now we put all the whole numbers and numerators together to get:

60 + 4 + 20 = 84 - whole numbers

10 + 12 + 15 = 37 - numerators

84 37/20 = 85 17/20 or 1717/20

4. Determine all unknown sides and angles to 1 decimal place.

Ksju [112]

Answer:

The unknown sides are 60.81cm and 51.57cm while the unknown angle is 58degrees

Step-by-step explanation:

4a) Given the following

Opposite side = 38cm (side facing the given angle)

Required

Adjacent and hypotenuse side

According to SOH CAH TOA

$tan \theta = \frac{opp}{hyp}\\tan 32=\frac{38}{hyp}\\hyp=\frac{38}{tan 32}\\hyp=\frac{38}{0.6249}\\hyp= 60.81cm$

Next is to get the adjacent

$Cos 32=\frac{adj}{60.81}\\adj=60.81cos32\\adj=60.81(0.8480)\\adj= 51.57cm$

Next is to get the missing

Since sum of angle in the triangle is 180degrees

32 + 90 + x = 180

122 + x = 180

x = 180 - 122

x = 58degrees

4x2 + 9y2 = 72 2x - y = 4 Which of the following is a solution to the system shown?

Ede4ka [16]

If you would like to solve the system of equations, you can do this using the following steps:

4x^2 + 9y^2 = 72
2x - y = 4 ... 2x - 4 = y
_________
4x^2 + 9y^2 = 72
4x^2 + 9 * (2x - 4)^2 = 72
4x^2 + 9 * (4x^2 - 16x + 16) = 72
4x^2 + 36x^2 - 144x + 144 = 72
40x^2 - 144x + 144 - 72 = 0
40x^2 - 144x + 72 = 0
10x^2 - 36x + 18 = 0
5x^2 - 18x + 9 = 0
(5x - 3) * (x - 3) = 0
1. 5x - 3 = 0 ... 5x = 3 ... x = 3/5
2. x = 3

1. y = 2x - 4 = 2 * 3/5 - 4 = 6/5 - 20/5 = -14/5
2. y = 2x - 4 = 2 * 3 - 4 = 6 - 4 = 2

1. (x, y) = (3/5, -14/5)
2. (x, y) = (3, 2)

The correct result would be (3/5, -14/5) and (3, 2).
