Answer:
the right answer would be 13
You would set up the problem like this: 3n-25=38
To solve for n:
3n-25=38
+25 +25 (Add 25 to both sides)
3n=63
/3 /3 (Divide by 3 on both sides)
n=21
The answer is 21.
Answer:
B, or second answer choice
Step-by-step explanation:
y - 
= m(x - 
)
y - 1/3 = 3/4 (x - 4)
B
The solution of the equation x2+7x is 0, -7 using the quadratic formula.
Step-by-step explanation:
x2 + 7x = 0
-b ± √
b2 - 4(ac)/ 2a
substitution,
a = 1, b = 7, c = 0
= -7 ± √(7)2 - 4(1 x 0) / 2 x 1
= - 7
± 7 / 2
x = 0 , -7
Answer:
4
Step-by-step explanation: 3 x 4 = 12.
12 - 8 = 4.
