The equation is
The total cost will be the same for the two services at
hours.

Answers

Answer: both services will cost the same if it is for 3 hours service.

Step-by-step explanation: Hope this helps.

Define x: Let x be the number of hours

Derrick Dogs sitting:

Fixed charged=$12

Hourly change=$5

Total charge=12+5x

Darlene dog sitting:

Fixed charged=$18

Hourly change=$3

Total charge= 18+3x

Find the total number of hours so that both cost are the same:

12 + 5x = 18 + 3x

5x - 3x = 18 - 12

2x = 6

x = 3

I need help with square roots. I would really appreciate it if you help me understand them. Thank you! I'll give you 10 points and a five star review for a good answer.

Answers

Answer: 9/8

Step-by-step explanation:

The square root of this is 9/8 because when you square 9/8, you get 81/64, and when you square root it, you get 9/8.

The easiest way tho is knowing that when you square a number and square root the square, you get the same number, cuz the square root cancels the square. Does that make sense?

Anyways hope this helped!

GUYS PLEASE HELP I MARK BRAINLIEST 5 STARS IM SORRY ABOUT THE POINTS I ONLY HAVE 13 Andre’s school orders some new supplies for the chemistry lab. The online store shows a pack of 10 test tubes costs $4 less than a set of nested beakers. In order to fully equip the lab, the school orders 12 sets of beakers and 8 packs of test tubes.

Write an equation that shows the cost of a pack of test tubes, t, in terms of the cost of a set of beakers, b.
t=b-4

The school office receives a bill for the supplies in the amount of $348. Write an equation with t and b that describes this situation.
b+t=348

Since t is in terms of b from the first equation, this expression can be substituted into the second equation where t appears. Write an equation that shows this substitution.
b+(b-4)=348

b=176

How much did the school pay for a set of beakers? $____

How much did the school pay for a pack of test tubes? $____

Answers

Answer:

this is not originally by me

Step-by-step explanation:

10t = b - 4

12b+8t = $348

This is a system of equations. I’ll be solving through substitution.

In the first equation. solving for b (the easier variable to isolate) gives you:

b = 10t + 4

Substitute this into the second equation:

12(10t+4) +8t = 348

120t+48+8t = 348

128t = 300

t = 2.34375 —> round it to the nearest cent to get 2.34 dollars

b = 10t+4

b = 10(2.34)+4

b = 27.4 dollars

Find all possible solutions for x and y such that △ABC is congruent to △DEF.

Use Phythagoras Theorem!!

the length pf a rectangle is 50 cm and its diagonal is 51 cm. work out the area of the rectangle, to the nearest square centimetre.

Answers

a² + b² = c²

50² + 51² = c²

2500 + 2601 = c²

5101 = c²

√5101 ≈ 71.42 cm.

Answer: Area of the rectangle = 102.5 cm² Round to 103 cm²

Step-by-step explanation:

The diagonal is the hypotenuse, c So subtract the square on the base (length) to find the altitude (height).

a² + b² = c²

a² + 50² = 51²

a² = 51² - 50²

a² = 2601 -2500

a² = 101 take the square root of both sides

a = √101

a = 10.04987562 Round to 10.05

Area = LW

Area = 50 × 10.05

Area = 102.5 cm² Round to 103 cm²
