x = # of hours the DJ was booked

$90 + $60x = $300

Subtract $90 from both sides.

$60x = $210

Divide both sides by $60

x = 3.5 hours

They had the DJ for 3.5 hours

Ilya [14]

Answer:

$Yearly = \$59.88$

Step-by-step explanation:

Given

$Monthly = \$4.99$

Required

Determine the yearly cost

To do this, we multiply the monthly subscription by 12

$Yearly = Monthly * 12$

$Yearly = \$4.99 * 12$

$Yearly = \$59.88$

Hence, the yearly servics cost is $59.88

Noa was walking in the forest and measured the circumference of two trees that he found. The first tree measured 37 5/8 inches a

rodikova [14]

Answer:

Step 4: 44 32/24 - 37 15/24= 8 17/24

Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.

Step-by-step explanation:

1. Let's review carefully all the steps taken by Noa to calculate the difference of the circumferences of the two trees.

Circumference Tree 1 = 37 5/8 inches around

Circumference Tree 2 = 45 1/3 inches around

Step 1: 45 1/3- 37 5/8

The measures are correct, no issues copying them.

Step 2: 45 8/24 - 37 15/24

Noa looked for common denominators

1/3 * 8/8 = 8 /24 is correct; 5/8 * 3/3 = 15/24 is also correct.

Step 3: 44 32/24 - 37 15/24

Noa looked for making the fraction part higher on the left side:

45 8/24 = 44 32/24 is correct because 24/24 = 1

Step 4: 44 32/24 - 37 15/24= 8 17/24

Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.

Anais bought 3 1/2 yards of ribbon. She had 2 feet 10 inches of ribbon left after trimming some curtains. How many inches of rib

Lesechka [4]

First, convert how many yards there were to inches. 3 1/2 yards gets you 126 inches. Next, find out how many inches 2 feet and 10 inches of ribbon is. 34 is your answer. Subtract 34 from 126 to get an answer of 92 inches (7 feet, 6 inches.)

stepladder [879]

Answer:

-1/8

Step-by-step explanation:

lim x approaches -6 (sqrt( 10-x) -4) / (x+6)

Rationalize

(sqrt( 10-x) -4) (sqrt( 10-x) +4)

------------------- * -------------------

(x+6) (sqrt( 10-x) +4)

We know ( a-b) (a+b) = a^2 -b^2

a= ( sqrt(10-x) b = 4

(10-x) -16

-------------------

(x+6) (sqrt( 10-x) +4)

-6-x

-------------------

(x+6) (sqrt( 10-x) +4)

Factor out -1 from the numerator

-1( x+6)

-------------------

(x+6) (sqrt( 10-x) +4)

Cancel x+6 from the numerator and denominator

-1

-------------------

(sqrt( 10-x) +4)

Now take the limit

lim x approaches -6 -1/ (sqrt( 10-x) +4)

-1/ (sqrt( 10- -6) +4)

-1/ (sqrt(16) +4)

-1 /( 4+4)

-1/8
