Answer:

3 hours

Step-by-step explanation:

Let the number for hours afterward be represented as: x

The veteran tutor charges $15 for the first session plus $60 per hour afterward.

This is expressed as

$15 + $60 × x

15 + 60x

The new college graduate charges $45 for the first session plus $50 per hour afterward.

$45 + $50 × x

45 + 50x

The number of hours these two must tutor in order to earn the same amount of money is calculated as:

Veteran tutor = New college graduate tutor

15 + 60x = 45 + 50x

60x - 50x = 45 - 15

10x = 30

x = 30/10

x = 3 hours

Therefore, the number of hours these two must tutor in order to earn the same amount of money is 3 hours

Luke and isabella make scale drawings.The scale from isabella's drawing is 6 m to 3 cm. The height of the fountain in isabella's
den301095 [7]

Answer:

The answer is "2.5 \ cm"

Step-by-step explanation:

While Luke is 5m to 2cm in size, it implies that every 2cm to Luke's drawing is 5m in real life. That real pond width must therefore be 5 m, given the fountain's width is 2 cm. As shown in the illustration, the step size for IsabelLa from the illustration to real life is \frac{6}{3} =2, which makes it simple to multiply any measure in the cm of her illustration by 2 to accomplish the exact size in m. So, in another direction around, they just have to divide the value by 2, instead of the divide from reality for drawing. So if the actual worth is 5m, it ought to be \frac{5}{2} = 2.5 \ cm in its width.

12. The sum of three consecutive integers is 12 more than twice the largest integer. Which of the following
baherus [9]

Answer:

OPTION 4

Step-by-step explanation:

Let the three consecutive numbers be n, (n + 1) and (n + 2).

Note that the largest number of the three is (n + 2) and the smallest is n.

So, according to the given data, the sum of all the three integers is equal to 1 more than twice more than the largest number.

Writing it mathematically, we have:

n + (n + 1) + (n + 2) = 12 + 2(n + 2)

This is OPTION (4) and is the answer,
