Answer:

x=1

Step-by-step explanation:

steps:

1: write the question question nicely.

2: the value outside multiply with the value inside but remember it should be separated by equal sign(=).(EXPAND).

3:Collect the like and unlike terms

4:remember - make x alone = ans.

so :write 6x/6=6/6

cancel 6 on both side and u will left with x onthe left side= and ans.

Answer:

$x = - \frac{19}{9}$

Step-by-step explanation:

5 - 2 (3x - 4) = 3 (x - 4) + 6

5 - 6x + 8 = 3x - 12 + 6

13 - 6x = 3x - 6

-6x - 3x = -6 - 13

-9x = 19 ÷ 9

x = 19/9

Halp me plz i stuck for so long (its part b)

vovangra [49]

The school can expect to raise 1500p for charity.

Explanation:

(a)

The possibility space is solved in the image attached.

(b)

20p for each player

30p for lollipop

Number of people = 120

Charity amount = ?

Out of 12 outcomes, the probability of getting 7 is 3

So, probability of getting 7 for 120 people = $\frac{3}{12} X 120$

= 30

Money earned from the players = 20p X 120

= 2400p

Cost of 30 lollipops = 30p X 30

= 900p

Money received for charity = 2400p - 900p

= 1500p

Therefore, the school can expect to raise 1500p for charity.

Answer:

Question 3

Given expression:

$\sf \left(\dfrac{-8}{9} \times \dfrac{1}{-5}\right)+\left(\dfrac{-8}{9} \times \dfrac{-7}{11}\right)$

Both parentheses share a common term.

To factor out a common term: ab + ac = a(b + c)

$\textsf{Factor out the common term }\dfrac{-8}{9}$

$\sf \implies\dfrac{-8}{9} \times \left(\dfrac{1}{-5}+\dfrac{-7}{11}\right)$

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

Question 4

To calculate the amount of money Rajni had to begin with, sum the three amounts she spent:

$\sf \implies total=10\frac14+25\frac34+16\frac12$

As $\sf a\frac{b}{c}=a+\frac{b}{c}$ , then:

$\sf \implies 10+\frac14+25+\frac34+16+\frac12$

Collect and sum the whole numbers:

$\sf \implies (10+25+16)+\frac14+\frac34+\frac12$

$\sf \implies 51+\frac14+\frac34+\frac12$

As $\sf \frac14+\frac34=\frac44=1$ , then

$\sf \implies 51+1+\frac12$

$\sf \implies 52+\frac12$

$\sf \implies 52\frac12$

Answer:

80.88

Step-by-step explanation:

The mean is the average of the numbers. To calculate that, just add up all the numbers, and then divide by how many numbers there are. In other words it is the sum divided by the count.

95 + 45 + 37 .....

divided by 24 (the total number of numbers)

1,941 / 24 = 80.875

80.875 rounded to the nearest hundredth = 80.88

(hundredths place)

Rounding rule: If the digit to the right of the place you are rounding to is 5 or more, then round up to the next digit.
