Evie is making wedding invitation cards in three different colours — blue, green and purple. She uses the different colours in the ratio 2 : 7 : 3. Evie has made 12 green cards so far and has 72 more green cards to make. Work out how many purple cards she will need to make.

she needs to make 36 purple cards.

Step-by-step explanation:

B : G : P

2 : 7 : 3

the 7 units belongs to the green and the qn stated that she needs to make 72 more cards after the 12 that she made in order to have the 7 units of green card.

Thus,

7 units = 12 + 72 = 84

1 unit = 12

3 units(amt of purple cards needed)= 12 × 3 = 36 #

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
