A trading token is in the shape of a trapezoid and has an area of 25 cm² if the bases are three and 7 cm what is the height of the tokens

Answers

Answer 1

Answer: $Area = (b1 + b2)/(2) *h$
$25 = (3 + 7)/(2) * h$
25 = $(10)/(2)$ *h
25 = 5h
5 = h
the height is 5

A China cup and saucer cost 12$. The cup on its own cost 3$ more than the saucer. Form an eqaution for s and solve it. Find the cost of the cup

Answers

If the cup = S + 3
and the
saucer = S
then

(S + 3) + S = 12
2s + 3 = 12
2s = 9
s = 4.50

So by itself the saucer costs $4.50. To find the cost of the cup look to the beginning of the problem where we learned that

Cup = S + 3
cup = 4.50 + 3
cup = 7.50

So the saucer is $4.50 and the cup is $7.50...

4.50 + 7.50 = $12.00

Erykah has 6 less than 3 times the number of stamps in her collection that Chris has in his. Let r equal the number of stamps Chris has. Which expression represents the number of stamps Erykah has? (Let r = the number of stamps Chris has)A. 6 - 3r
B. 3r + 6
C. 3r - 6
D. 6 + 3r

Answers

C. 3r-6 is the answer

Answer:

Step-by-step explanation:

let r be the number of stamps Chris has then

3times this amount is 3r and less 6 is subtract 6 from 3r, hence

Erykah has 3r - 6 stamps → C

What can be multiplyed by 3 to equal 40

Answers

Let's say that the number we are looking for is called 'x'.

3 * x = 40
3x = 40

To solve for 'x', we will need to divide both sides by 3.

3x/3 = 40/3

$x = \boxed{\bf{(40)/(3) = 13(1)/(3)}}$

40/3 or 13 1/3 can be multiplied by 3 to get 40.
