Answer: for a sum of 7 would either be 6 and 1, 5 and 2 or 4 and 3. you can roll a double 1,2,3,4,5,6. the sum of 8 would be 2 and 6, 3 and 5 and a double 4,

Step-by-step explanation:

well the there are six sides on a die so 6 x 2 is 12 so the max sum you can get is 12. So you take 7 and you start adding up to 7, same thing for sum of 8. since there is 6 sides and a pair of dices you will roll six doubles

Which equation is equal to 4a+2b=10<br> A. b=-2a+10<br> B. 2a+5<br> C. b=-2a+5<br> D. b=2a+10

nata0808 [166]

4a + 2b = 10

you are solving for b

isolate the b

subtract 4a from both sides

4a (-4a) + 2b = 10 (-4a)

2b = 10 - 4a

divide 2 from both sides to isolate the b

2b(/2) = (10 - 4a)/2

b = (10 - 4a)/2

b = 5 - 2a

C) b = -2a + 5 is your answer

Find the surface area of the cylinder.

Ronch [10]

Answer:

exact: 48pi cm^2

approximate: 150.8 cm^2

Step-by-step explanation:

SA = 2 * (pi)r^2 + 2(pi)rh

SA = 2 * pi * (3 cm)^2 + 2(pi) * 3 cm * 5 cm

SA = pi(18 cm^2 + 30 cm^2)
