Answer:

P( green or blue) = 9/20

P( green, yellow or blue) = 3/4

P( green, red or blue) = 7/10

Step-by-step explanation:

There are 40 slips in all, Green: 15, Red: 10, Blue: 3, Yellow: 12.

P( green or blue) = green or blue / total

= (15 + 3)/ 40

= 18/40

= 9/20

P( green, yellow or blue) = green yellow or blue / total

= (15+12 + 3)/ 40

= 30/40

= 3/4

P( green, red or blue) = green red or blue / total

= (15+10 + 3)/ 40

= 28/40

= 7/10

60 points on the line! If you can do this paper! Only 2 questions!

Stolb23 [73]

So y=mx+b
the 'm' part means the slope which is found by 'rise/run'
a. y=2x+3 or y=2x+3
b. y=-1x+6
c. i'm not sure what this part means
d. this means 'what values will work for x and y in both equations at once so
y=-x+6 and y=2x+3
y=-x+6
add x to both sides
x+y=6
subtitute 'y=2x+3' for y in x+y=6
x+(2x+3)=6
collect like terms
3x+3=6
subtract 3 from both sides
3x=3
divide both sides by 3
x=1
sibtitue into x+y=6
1+y=6
subtract 1 from both sides
y=5

(1,5) is the solution (x,y)

Question 2
so amount of peanuts (x) =60%
ammount of almonds (y)=40%
y=2(1/3x) or y=2/3x
so there is a mixture that is8/10 almonds
for
a. i'm not sure about this one
b. so 60% of 5 pounds=3 pounds
40% of 5 pounds=2pounds
we need to find out how many pounds, times 8/10, = 2pounds

she will need 2.5 pounds of the pure peanuts and 2.5 pounds of the almond-peanut mixture

Simplify – 2(7x – 3)

ANTONII [103]

All you need to do here is multiply the outside number by both 7x and -3.

When done correctly it should look like this:

-14x+6

Thats the answer.

7 times 2 gives you 14 but when multiplying mixed signs it turns negative so it would be -14.

negative 3 times negative 2 gives you 6. Both signs are negative, and you would suppose it would turn into a negative but thats only true when both signs are mixed. Both the 3 and the 2 are negative, making the signs the samez giving you positive

Dont forget to make this the brainliest answer to help those in need. also add a 5 star and a heart. thanks for the support hope it helped. have a nice day
