x = lbs
y = total cost
ABC shipping: $7 + $1x = y
XYZ shipping: $10 + $0.75x = y
We set each equation equal to the other.
$7 + $1x = $10 + $0.75x. Subtract $7 from both sides and subtract $0.75x from both sides
$0.25x = $3. Divide each side by $0.25.
x = 12 lbs
When a package is 12lbs the cost is the same.
Answer: ' i think the answer is x
/10 + 1/8 . let me know if this is wrong !
M1 = 65°
M2= 75°
all three angles is 180°
M7 = 40°
7 and 6 are identical angles corresponding
M6= 40°
Answer:
The length of each side is 4 m
Step-by-step explanation:
The volume of a cube is given by
V = s^3 where s is the side length
64 = s^3
Take the cube root of each side
64 ^ (1/3) = s^3 ^ (1/3)
4 = s
The length of each side is 4 m
(4x - 10) + (12x + 6) = 68
16x - 4 = 68
16 x = 72
x = 4.5
So, 12 (4.5) + 6 = 60
