Answer:

0.63333333333... or 19/30

Step-by-step explanation:

<u><em>Here's how to subtract 1/5 from 5/6: </em></u>

5/6-1/5

<u>Step 1</u>

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 5 by 5, and get 25.

Then we multiply 1 by 6, and get 6.

Next we give both terms new denominators ~ 6 × 5 = 30.

So now our fractions look like this:

25 /30  − 6 /30

<u>Step 2 </u>

Since our denominators match, we can subtract the numerators.

25 − 6 = 19

So the answer is:  19 /30

<u>Step 3 </u>

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

No, we can't. Therefore the answer is 19/30, or in decimal form, 0.633333333.

What is X squared +3x-70
Aleksandr-060686 [28]

Answer:

x = 7, x = -10

Step-by-step explanation:

x^2+3x-70 = 0

Use the quadratic formula.

x = \frac{-3 + \sqrt{3^2-4(1)(-70)} }{2(1)} \\x = \frac{-3 - \sqrt{3^2-4(1)(-70)} }{2(1)} \\

Solve.

x = 7, x = -10

You can also factor if you want - that is a faster method.

The area of a trapezoid is 168cm2. The height is 16cm and the length of one of the parallel sides is 9cm. Find the length of the
dmitriy555 [2]

Answer:

12 cm

Step-by-step explanation:

The formula for the area of a trapezoid is written as:

1/2(b1 + b2)h

h = height = 16 cm

b1 = Length of one parallel side = 9cm

b2 = Length of second parallel side = ?

Area of trapezoid = 168cm²

The formula to find the length of the second parallel side =

b2 = 2A/h - b1

b2 = 2 × 168/16 - 9

b2 = 336/16 - 9

b2 = 21 - 9

b2 = 12cm

Therefore, the length of the second parallel side is 12 cm

2 + 3 × (8 + 53 ÷ 1)<br><br> Can please include the working to it. Thank you,
luda_lava [24]

Step-by-step explanation:

2 + 3 × (8 + 53 ÷ 1)

we first work out the equation in the brackets

so...

(8 + 53 ÷ 1)

division comes first so we divide 53÷1 which is 1 so the equation looks like this:

(8+53)

we work this out and get

61

then we work the rest out

2 + 3 × <u>61</u>

multiplication comes first so...

3×61= 183

and

2+ 183= 185

Therefore 2 + 3 × (8 + 53 ÷ 1)= <u>185</u>

Hope this helped- have a good day bro cya)
