The sum of x and 10 is less than -6

1 answer:

6 0

Try breaking these into sections.

Twice: 2 times

The sum of: add

A number: choose a variable, like x

---Thus "the sum of a number and 4" becomes "add x and 4" which, mathematically, is "x+4"

-----Continuing to put it all together, "Twice the sum of a number and four" becomes "2 times (x+4)" which, mathematically, is "2(x+4)"

Is: equals

-------"Twice the sum of a number and four is" becomes "2(x+4)="

23 less than: subtract 23. This one tends to trick people; "23 less than" will become "__ - 23", NOT "23 - __"

three times the number: 3 times x

---"23 less than three times the number" becomes "subtract 23 from 3 times x" which, mathematically, is "3x-23"

-------So the final phrase: 2(x+4)=3x-23"

6 cousins inherited a total of 58 of their great aunt's assets which they divided evenly what fraction of their great aunt's ass

mina [271]

Answer:

9 1/9 per cousin

Step-by-step explanation:

if the aunt has 58 items to be distributed to 6 cousins, we would set a fraction of 58/6. performing that is 9 with 4/6 left over.

since there is 6 cousins, there will be 2/3 divided by 6 = 2/18, or 1/9

What is 3:120 equivalent to

fenix001 [56]

1:40 because if we think of this just like a fraction $\frac{3}{120}$ that simplifys down to $\frac{1}{40}$ and because fraction simplifications are similar (related to each other) we can concur that these would be too.

Enjoy!=)

What survival rate in the 10th year would make the average of loss over the 10 year period equal to 38.0%

Marat540 [252]

Answer: 63%

Step-by-step explanation:

First step

Find the 10th year rate of loss that will make the average of loss over the 10 years to equal 38.0%.

Assume this rate is x;

$\frac{(36.2 + 29.0 + 46.2 + 37.5 + 40.9 + 40.0 + 32.6 + 40.5 + 40.1 + x)}{10} = 38.0\\\\\frac{343 + x}{10} = 38\\\\x = 380 - 343\\\\x = 37$

x = 37%

Second step - Survival rate

The survival rate is calculated by;

= 1 - rate of loss

= 1 - 37%

= 63%

Halp?

____ [38]

The formula for finding the volume of a rectangular prism (the cargo area of the truck is the shape of a rectangle in 3D; a rectangular prism) is V = (l)(w)(h); where l = length, w = width, and h = height.

First, substitute the known values into the equation:

l = 8.5

w = 6

h = 10.5

V = (8.5)(6)(10.5)

(Note: .5 = 1/2)

Now, all we need to do is simplify:

V = 535.5 ft³ OR 535 1/2 ft³

(Note: ft³ is the condensed form of cubic feet)

You can pick whichever form your test directs you to use. They are both the same value though.

Hope this helps!
