What is the value of (3-5)*(2) — 16- 2?<br> -40<br> 0 -16<br> ооо<br> 24<br> 56
valina [46]

if i didn't understand it wrong, * is (3-5) x (2)

so,

(3-5)x 2-16-2

=-2x2-16-2

=-4-16-2

= -22

But if * means (3-5)^2 -16-2

then its,

(3-5)^2-16-2

=(-2)^2 -18

=4-18

= - 14

But looks like both of them are not in your choice at all

If the ratio of red roses to pink roses is 5 to 4 and there are a total of 45 roses, how many of them are red?
RUDIKE [14]

Answer: There will be 25 red roses and 20 pink roses.

Step-by-step explanation: If the ratio is 5 to 4 then we can add 5 and 4 together to get 9. 45 is divisible by 9. 9 goes into 45, 5 times. If we multiply 5 by 5 then it will be 25 which is 5/9 of 45. Then if we do the same thing but we multiply 4 times 5 then we will get 20 which is the other 4/9 of the ratio.
