Answer: (2,30), (5,66)

Step-by-step explanation: I truly don’t know if this is correct, but at the beginning, the crystal was already 6 mm. She then realized it increased 12 mm every hour, so if one hour passed, it would be 12+6= 18. Okay, so now that we know that, we multiple the hours by 12 and then add the 6.

12x2= 24

24+ 6= 30,

12x5= 60

60+6= 66

If Maya orders a $1.89 drink, 3 cookies at $.99 each, and 2 slices of pizza at $2.50 each. How much did Maya pay for her order?
sweet [91]

Answer:

$9.86

Step-by-step explanation:

Frist you read the problem and you see that she pays $1.89 for one drink

so you write down $1.89

then 3 cookies for $0.99 so you multiply $0.99 by 3 and you get $2.97

so you write down $2.97

next 2 slices of pizza for $2.50 so you multiply 2 by $2.50 and you get $5.00

so you write that down

lastly you and the answers you wrote down and you get $9.86

Maya payed $9.86 for her order.

Please do them step by step;
ELEN [110]
For the first one c-9=(2)(4)+6
You are gonna multiply 2 and 4 first, 2*4=8. Now you have c-9=8+6. 8+6=14. So now the equation is c-9=14. Now we are going to add 9 to both sides. So c=23
For the second equation 10+y=90. We are going to subtract 10 from both sides. So, y=80.
Third, add 4 to both sides. a=10.
Fourth, subtract 8 from both sides. d=-9
Fifth, 5+2(3+4)=-x.
First we are going to add 3 and 4. 3+4=7. 5+2(7)=-x. Next we are going to multiply 2 and 7. 2*7=14. 5+14=-x. 5+14=19. So our equation is 19=-x. Next we are going to multiply both sides by -1. Making our final equation x=-19.
c=23
y=80
a=10
d=-9
x=-19
I hope that helps, if you need any further explanation just ask.<span />

Two cards are drawn without replacement from a standard deck of 52 cards. What is the probability that one of the cards is red a
alukav5142 [94]
Total cards = 52
Total red cards = 26
Total black cards = 26

P(one red and one black) = P(red and then black)+ P(black and then red)
P(one red and one black) =(26/52)(26/51) + (26/52)(26/51)
P(one red and one black) = 26/51 (Answer A)
