Sara has 24 sweets
Tresset [83]
<h2>Hello!</h2>

The answer is:

The expression for the number of sweets that Sara and Tim have now, are:

Sara=(17-x)Sweets\\\\Tim=\frac{(24+x)Sweets}{2}

<h2>Why?</h2>

To write the expressions for the number of sweets that Sara and Tim have now, we need to follow the next steps:

Sara starts with 24 sweets and Tim starts with 24 sweets

Sara=24 Sweets\\Tim=24 Sweets

Then, Sara gives Tim x Sweets

Sara=(24-x)Sweets\\Tim=(24+x)Sweets

Then. Sara eats 7 of her Sweets

Sara=(24-x-7) Sweets\\Sara=(17-x )Sweets\\Tim=(24+x) Sweets

Then, Tim eats half of his sweets

Sara=(17-x)Sweets\\\\Tim=\frac{(24+x)Sweets}{2}

So, the expression for the number of sweets that Sara and Tim have now, are:

Sara=(17-x) Sweets\\\\Tim=\frac{(24+x)Sweets}{2}

Have a nice day!

A triangle has a height that is 5 units shorter than its base. If b represents the base and h represents the
11111nata11111 [884]

Answer: A = (b²-5b)/2

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Base =b

Height = h = b-5 (the height is 5 units shorter than the base)

Since:

Area of a triangle (A)= (base x height) ÷ 2

Replacing with the values given:

A = [b (b-5)] ÷2

A = (b²-5b)/2

Feel free to ask for more if needed or if you did not understand something.
