Sheila can pay her hotel bill in Euros (€) or Pounds (£).
The bill was €425 or £365 when the exchange rate was £1 = €1.14.
In which currency was the bill cheaper?
Show all your working.​

Answers

Answer:

£365 is cheaper than  €425.

Step-by-step explanation:

We want to convert both prices to the same currency. It is easier to convert pounds to euros, as the exchange rate uses £1.

€425 or £365

£365 = €(365 * 1.14)

£365 = €416.10

€425 > €416.10

£365 is cheaper than  €425.

(SUBSTITUTION ASAP)

Answers

x = -2, y = -1

Substitution method:

2x + 3y = -7

y = 8x + 15

2x + 3(8x + 15) = -7

2x + 24x + 45 = -7

26x = -52

x = -2

Substituting x value back into 1st equation for y:

2(-2) + 3y = -7

3y = -3

y = -1

Which graph shows the following system of equations and its solutions? -0.1x-0.3y=1.2 and 0.2x-0.5y=2

Answers

Answer:

Option b is the correct answer as both the equations are true for given solution.

Step-by-step explanation:

Given equations are:

-0.1x-0.3y=1.2

0.2x-0.5y=2

We can observe each graph and find the point that is the solution and put the point in the equations to know if that point is the solution

For option A:

(0,4)

Putting x=0 and y = 4 in both equations

[tex]-0.1(0)-0.3(4)=1.2\\0-1.2 =1.2\\-1.2 \neq 1.2\\0.2(0)-0.5(4)=2\\0-2 = 2\\-2 \neq 2[/tex]

This is not the correct answer as both equations are not true with this solution

For Option B:

(0,-4)

Putting x = 0 and y = -4 in both equations

[tex]-0.1(0)-0.3(-4)=1.2\\0+1.2 = 1.2\\1.2 = 1.2\\0.2x-0.5y=2\\0.2(0)-0.5(-4) = 2\\2 = 2[/tex]

Both equations are true for (0,-4) hence it is the solution of the system.

For Option C:

(4,0)

[tex]-0.1(4)-0.3(0)=1.2\\-0.4-0 = 1.2\\-0.4 \neq 1.2\\0.2x-0.5y=2\\0.2(4)-0.5(0) = 2\\0.8 \neq 2[/tex]

Not true for both equations

Hence,

Option b is the correct answer.

Step-by-step explanation:

Trust me this is easy

Answer:

4x+2 =90°

3x+2=68°

x=22

Step-by-step explanation:

The interior angles of a triangle always add up to 180° so you will add the angles together and set them equal to 180° to solve for x. You will find that x should be equal to 22. Plug 22 into each equation to find the angle measure.

I don't know what essay format looks like ;n;Having to be at school by 7:30 or 7:00 in the morning eventually turns teens and kids into zombies, and not in a healthy way. Most days, kids, especially teens, come home with loads of homework, causing them to go to bed late, leaving them with only a few hours of sleep. Early times such as these can also cause stress, which can lead to loss of sleep too. This means that kids and teens still have to get up early in the morning and sit through hours of learning with only a few hours of sleep. This can be extremely harmful to teens' health and grades. With this being said, later times such as 8:00, 8:30, or maybe even 9:00 would be a better option considering the health and standards of teens and kids. The reason for this is because schools always start in the mornings, and some teens can barely wake up for this movement, so they fall asleep when set to do work and tasks. Every school thinks that they can keep their kids awake by starting maybe an hour later than Elementary schools, well truthfully they're wrong. Many teens always stay up late, and nothing is going to stop them from it because they want to go to sleep when they feel like it is not a set time. The reason the kids that are falling asleep and not doing no work are called zombies. In our view, they are always "moaning" and are always looking tired and acting tired. Kids at school with barely any rest act and sometimes look the same exact way.
