Answer:
x = 16
Step-by-step explanation:
Verticle angles are always congruent, so:
(8x + 15) = 143
Now, we can solve to isolate x:
8x + 15 - 15 = 143 - 15 (subtract 15 from both sides)
8x/8 = 128/8 (divide both sides by 8)
x = 16
You can always plug in the value of x to the original equation to check your answer:
8(16) + 15 = 143

Answer:
(-5,29)
(2,1)
(4,-7)
Step-by-step explanation:
y = -4x + 9
When x is -5;
y = -4(-5) + 9 = 29
When x is 2;
y = -4(2) + 9 = 1
When x is 4;
y = -4(4) + 9 = -7
Answer:
11 and 13
Step-by-step explanation:
let smaller odd number be x
larger odd nuber be x+2
according to the question algebraic expression can be written as
6x+3(x+2)=105
6x+3x+6=105
9x=105-6
9x=99
x=99/9
x=11
larger number=x+2
11+2
13
