A is 40
B is 50
C is 115
Explanation, A is the same as the opposite, A + B + 90 = 180, and C + 65 = 180
12q+3r=15
-4q-4r=-44
-4q=-44+4r
q=11-r
12(11-r)+3r=15
132-12r+3r=15
132-9r=15
117=9r
r=13
-4q-4(13)=-44
-4q-52=-44
-4q=8
q=-2
Answer:
18 1/2
Step-by-step explanation:
Let’s start out by breaking down the equation
1. eight more than. we know this must mean we are adding 8, so (+ 8)
2. the difference of a number and sixteen. we know the number (x) and 16 are being subtracting as indicated by the word difference, so (x-16)
now let’s combine them (x-16) + 8
let’s set it equal to 0, just to confirm it is correct.
(x-16) +8 = 0
x-16 = -8
x = 8
so substituting x for 8 in the translation: (8-16) + 8 = 0
-8 +8=0
it is correct! :)
