Step-by-step explanation:

x > -7

Open circle means the solution does not include -7 and it is more than -7

Answer:  6:5 ; 18:15 ; 36:30

Step-by-step explanation:

6/5 = x/15

5x = 6(15)            use cross multiply

5x = 90

x = 18

6/5 = 36/x

6x = 5(36)            use cross multiply

6x = 180

x = 30

Answer:

Answer below

Step-by-step explanation:

For every 6 taxis, there are 5 busses

if there are 15 busses, thats 3 sets of 5

6x3 is 18. so for every 15 busses, there are 18 taxis

If there are 36 taxis, thats 6 sets of 6

since there are 5 busses for every 5 taxis

5x6 is 40

for every 30 busses, there are 36 taxis

Which do you think it is?

Answer:

41 years approx

Step-by-step explanation:

Given data

P=  £3000

R=3%

Simple Interest= £3720

Time=???

We know that from the simple interest expression

SI= PRT/100

substitute

3720= 3000*3*T/100

Make T subject of the formula

T= 3720*100/3000*3

T= 372000/9000

T= 41.33

Hence the number of years is 41 years approx

Answer:

Original coordinates of F is (2,1)

Step-by-step explanation:

when DEFG is dilated by a scale factor of 1/2 with a dilation center of (0, 0), coordinates of point F' will be

( 2 x 1/2, 1 x 1/2 ) = ( 1, 1/2 )

Answer:

105 for 3 hours

Step-by-step explanation:

First we have to find that how much he is charged for 1 hour.

140 : 4 = 35 per hour

Then we have to find how much he is charged for 3 hours by multiplying with 3.

3 x 35 = 105 per 3 hours

Answer:

£105

Step-by-step explanation:

let y represent the unknown amount

£150 = 4 hrs

y = 3 hrs

we then cross multiply

£150 x 3 hrs = y x 4 hrs

450= 4y

divide both sides by 4

450/4 = 4y/4

105 = y

Answer:

Not probabillity of picking a green marble is 80%

Step-by-step explanation:

Answer:

.80 or 4/5

Step-by-step explanation:

Probability is all about figuring out what you are or not going to get.

One good trick of figuring this out is taking what you don't want, (here its green marbles) take them out, then add all the marbles (G,B,R) and divide. Here you are dividing 8 by 10 which comes out to .80

The only other thing to do is simplify if needed. .80 turns into 8/10 and the only thing that 8 and 10 are divisible by is 2 so it would turn into 4/5

Hope this info can help ;)

Answer: the answer is 8 and 3

Step-by-step explanation:

factors are numbers that can be multipiled together to find a whole number. since 8 and 3 are being multiplied together to get 24, 8 and 3 are factors of 24.

Answer:

-14°C

Step-by-step explanation:

Given that,

The mean temperature for the first 4 days in January was -4°C.

The mean temperature for the first 5 days in January was -6°C.

Mean = sum of observations/no. of observations

For first 4 days,

[tex]-4=\dfrac{S_4}{4}\\\\S_4=-16\ ...(1)[/tex]

For first 5 days,

[tex]-6=\dfrac{S_4+T}{5}\\\\S_4+T=-30\ ..(2)[/tex]

Let the temperature on 5th day is T. So,

Put S₄ = -16 in equation (2).

-16 + T = -30

T = -30+16

T = -14°C

So, the temperature on the 5th day is -14°C.

Answer:

y = 5x + 14

Step-by-step explanation:

Let x = number of day and y = number of drawings.

She draws 5 drawings per day, so in x days, she draws 5x drawings.

She started with 14 drawings, so the total number of drawings in any day, x, is

5x + 14.

The equation is

y = 5x + 14
