Answer:
x=4
Step-by-step explanation:
-2x-5-x=-17
-3x-5-x=17
-3x=-17+5
-3x=-12
x=-12÷-3
x=4
make me as brilliant answer
70a + 55b = 905
a + b = 14
55a + 55b = 770
(70a-55a) + (55b-55b) = 905 - 770
15a = 135
a = 9
a + b = 14
9 + b = 14
b = 5
9/20, 3/5, 7/10, 23/30, 4/5
That means to multiply right? it's 10,800
Solve for x in the first equation:
X -2 = 1/3
Add 2 to both sides:
X = 2 1/3
Now replace x in the second equation:
2 1/3 ^2 - 4(2 1/3) + 4
5 4/9 - 9 1/3 + 4 = 1/9
Answer is B.
