The square of the quantity 17 less than x

Mathematics

Hi! so you have the number x, and you're trying to find the square of x - 17. since order of operations is important here, you should put x - 17 in parenthesis first to get (x - 17). then square it to get (x-17)^2!

A(n) = -5 + 6(n - 1)a(n)=−5+6(n−1)a, left parenthesis, n, right parenthesis, equals, minus, 5, plus, 6, left parenthesis, n, min
DENIUS [597]

Answer:

The 12th term is 61

Step-by-step explanation:

I will assume that your a(n) = -5 + 6(n - 1) is correct; the rest is redundant (duplicative, unneeded).

To find the 12th term, substitute 12 for n in the above formula:

a(12) = -5 + 6(12 - 1) = -5 + 6(11) = 66 - 5, or 61

The 12th term is 61

Roger makes 70 gallons of pink paint by mixing 21 gallons of white paint. what part of every gallon is from red paint?
forsale [732]
There are 49 gallons of red paint.
I figured it out by doing the following:

70 \:  -  \: 21 \:  =  \: 49
If you subtract the gallons of pink paint (21) from the total number of gallons (70), then you get the number of gallons of red paint (49) because 49 + 21 = 70. I hope that helps :)

anzhelika [568]

Answer

1946.8 cm

Step-by-step explanation:

you first need to find the circumference of the tire. to do this you use the formula C=d(3.14)

you plug in the 62 to the d

62 times 3.14 = 194.68

and multiply that by 10 because it is 10 revolutions to get 1946.8 cm

Needs help answering
Savatey [412]

Answer:

b = 100°

c = 30°

Step-by-step explanation:

b = 100° bc the two angles are supplementary, that is, together they form a straight angle and add up to 180°.

c = 30°

because a + b + c = 180. There's 180° in a triangle.

How to do 2/5 = (x-3)/(7x+15)
Zigmanuir [339]

Answer:

x =  - 5

Step-by-step explanation:

To work out this question you have to first cross multiply.

\frac{2}{5} =  \frac{(x - 3)} {(7x + 15)}  \\ \\  2(7x + 15) = 5(x - 3)

When you cross multiply you will get the equation above. Therefore

(2 \times 7x) + (2 \times 15) = (5 \times x) \\   - (5 \times  3) \\ \\ 14x + 30 = 5x - 15 \\ \\ 14x - 5x =  - 30 - 15 \\ \\ 9x =  - 45

Therefore

\frac{9}{9} x =  \frac{ - 45}{9}  \\ \\ x =  - 5
