Answer:

$\huge{ \bold{ \boxed{ \text{30m + 21}}}}$

Step-by-step explanation:

$\text{4(9m + 3) + 9 - 2(3m) }$

$\text{Step \: 1} : \text{Distribute \: 4 \: through \: the \: parentheses}$

➵ $\text{36m + 12 + 9 - 2(3m)}$

$\text{Step \: 2} : \text{Multiply \: 2 \: by \: 3m}$

➵ $\text{36m + 12 + 9 - 6m}$

$\text{Step \: 3 : \: Combine \: like \: terms}$

$\text{Like \: terms \: are \: those \: which \: have \: the \: same \: base.}$

➵ $\text{36m - 6m + 12 + 9}$

➵ $\text{30m \: + 12 + 9}$

$\text{Step \: 4 : Add \: the \: numbers}$

➵ $\text{30m \: + \: 21}$

Bridget and Caroline win some money and share it in the ratio 7:3. Bridget gets £40 more than Caroline. How much did they get al

solong [7]

Answer:

£100

Step-by-step explanation:

if the ratio is 7:3, the difference between them is 7-3 . = 4.

So,

4x = £40

Now, calculate x

x = £10

Now,

we are able to calculate:

7x (Bridget's share) = £70

3x (Caroline's share) = £30

Sum = £100

Hope this helps.

Good Luck

15. Construct the slope-intercept form equation of the line passing through (-5,23) and (10,-5).

Radda [10]

Answer:

15y = -28 x + 205.

Step-by-step explanation:

Slope intercept form of equation is y = mx + c where m is slope and c is the y intercept.

Now slope of line passing through points (-5, 23) and (10, -5):

$m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} } = \frac{-5 -23}{10 + 5} = \frac{-28}{15}$

Now equation of line:

y = mx + c

substituting the value of m in above expression,

$y = -\frac{28}{15} x + c$

Now, since the line is passing through the point (-5, 23) therefore, x = -5 and y = 23. By substituting these values in above equation,

$23 = -\frac{28}{15} \times (-5) + c$

$23 = \frac{28}{3} + c$

$c = 23 - \frac{28}{3} = \frac{69 - 28}{3} = \frac{41}{3}$

So equation of line in slope intercept form:

$y = -\frac{28}{15} x + \frac{41}{3}$

Further solving,

15y = -28 x + 205.
