Answer

-4y - 67 = y - 17


Step by step explanation

Let y be the unknown number.

-4 times a number minus 67 is equal to 17 less than the number.

The number is y

times means multiplication

-4y - 67 = y - 17

Hope you will understand the concept.

Thank you.

<u>Answer:</u>

-4y - 67 = y - 17

<u>Step-by-step explanation:</u>

We are given y to be assumed as the unknown number here in this word problem.

So we will establish the equation step by step.

-4 times a number: the number y is multiplied by -4 to give -4y

minus 67: 67 is subtracted from -4x to give -4y - 67

is equal to 17 less than the number: it means that half of the already constructed equation is equal to y - 17

so the full equation will be:

-4y - 67 = y - 17

bixtya [17]
I believe the form you mean is

4.8732 x 10^{7}

Well move the decimal point of the 4.8732...7 places to the right.

48,732,000

Now find that answer. 

The answer is A.

The circumference of the inner circle is 66 ft. The distance between the inner circle and the outer circle is 44 ft. By how many
Ray Of Light [21]

Answer:

  276 4/7 ft

Step-by-step explanation:

Let r1 represent the radius of the inner circle. Then its circumference in feet is ...

  C = 2πr

  66 = 2π(r1)

If the radius of the outer circle is (r1 +44), then its circumference is ...

  C = 2π(r1 +44) = 2π(r1) +2π(44)

  C = 66 +88π

Then the difference in the circumferences is ...

  (66 +88π) - (66) = 88π

Using the given value of π, the difference in circumferences is ...

  (88 ft)(22/7) = 1936/7 ft = 276 4/7 ft

Which method would be more efiicient to solve the system y=1/2x and 2x+3y=28
Licemer1 [7]
Probably the subsitution method


y=1/2x
subsitute that fr y

2x+3(1/2x)=28
2x+3/2x=28
times 2 both sides
4x+3x=56
7x=56
divide by 7 both sides
x=8
sub back

y=1/2x
y=1/2(8)
y=4

(x,y)
(8,4)

Write the equation of the line that has the indicated slope and contains the indicated point. Express the final equation in stan
OlgaM077 [116]

Answer:

y = 1/2x + 5

Step-by-step explanation:

Given :

Slope, m = 1/2

(x1, y1) = (6, 8)

y - y1 = m(x - x1)

y - 8 = 1/2(x - 6)

y - 8 = 1/2x - 3

y - 8 + 8 = 1/2x - 3 + 8

y = 1/2x + 5

Stamdard form of equation :

y = mx + c

Hence, equation is :

y = 1/2x + 5
