Hello!
2x + 1 = 5x - 8
Solve by subtracting both sides by 2x:
2x - 2x + 1 = 5x - 2x - 8
1 = 3x - 8
Add 8 to both sides:
1 + 8 = 3x - 8 + 8
9 = 3x
Divide both sides by 3:
9/3 = 3x/3
x = 3
What we know: Lucy's snake eat's 2 mice a week.
To find the answer, you'll have to multiply 2 by 6.
So, since Lucy's snake eats 2 mice a week for 6 weeks.
To find the amount of mice her snake has eaten in the past 6 weeks you'll have to multiply 2 and 6.
2x6=?
------------------------------------------------------------------
The first week the snake ate 2 mice.
The second week the snake ate 2 mice.
The third week the snake ate 2 mice.
The fourth week the snake ate 2 mice.
The fifth week the snake ate 2 mice.
The sixth week the snake ate 2 mice.
Your answer would be: 12
Answer:
x = 10
Step-by-step explanation:
Perimeter of a triangle = the sum of the three sides.
In an isosceles the legs are equal (2x - 6) and the base is x
Perimeter = (x) + (2x - 6) + (2x - 6)
38 = 5x - 12
38 + 12 = 5x
50 = 5x
10 = x
h = 6
l = 8
w = 6
surface area = 2 (wl +hl +hw) =
2( (6*8) +(6*8)+(6*6)) =
2(48 +48 +36)=
2(132)= 264 square inches
