Step 1: Add 5129 to both sides.
w−5129+5129=2329+5129
w=7458
Answer is C
Hello!
We want isolate the n. This is
6,2 n - 3,7 n = 85 + 45
2,5 n = 130 . ( 10 )
25 n = 1300
n = 1300 / 25
n = 52
Hope this helps, good studies.
Answer:
X=4-2y/6
Y=4-6x/2
Step-by-step explanation:
For X:
1) -2y
Once you subtract 2y you are left with 6x=4-2y
2) Divide by 6 on both sides to get x alone
That would give you your answer of X=4-2y/6
For Y:
1) -6x
After subtracting 6x you would have 2y=4+6x
2) Like the steps above, you divide by 2 on both sides and that would give you your answer of Y=4-6x/2
Answer:
f(-1) = 2
f(0) = 3
Step-by-step explanation:
f(a) = 3a - a²
f(4)= 3*4-4²= -4 ⇒ correct
f(3)= 3*3-3²= 0 ⇒ correct
f(-1) = 3*(-1)-(-1)²=-3+1= -2 ⇒ incorrect
f(0) = 3*0-0²= 0 ⇒ incorrect
f(-5) = 3*(-5)-(-5)²= -15-25= -40 ⇒ correct
Charges 0.50 per mile with a 5 dollar surcharge. Spending at most 30 dollars, the equation would be:
0.5x+530
To find how many miles they can travel/the solution, solve the inequality:
Subtract 5 from both sides.
Divide both sides by 0.5.
They can travel (at most) 50 miles.
Hope this helps :)
