Need help ASAP can figure out
s344n2d4d5 [400]

Answer:

Answer is D

Step-by-step explanation:

First use sine to figure out x

so "sin(31) = 12 ÷ x"

mulitply both sides by x and you get "x * sin(31) = 12"

divide both side by sin(31) so you get "x = 12 ÷ sin(31)"

after plugging it in a calculator, you get 23.2992 and just rounf to the nearest tenth and you get 23.3

1. Evaluate the expression -6.3a +2(a - b) for a = -2 and b = 1.1.
sasho [114]

Answer:

D or 6.4

Step-by-step explanation:

-6.3*(-2) + 2(-2 - 1.1)

- 6.3 * - 2 = 12.6 Notice that the two minus signs become a +

(-2 - 1.1)= (-3.1)   Multiply -3.1 * 2 = - 6.2

12.6 - 6.2 = 6.4
