Answer:
Step-by-step explanation:
Adding both equations
4x+5y+5y-4x=19+38
10y = 57
y= 5.7
Subtracting equation i from ii
5y-4x-4x-5y=38-19
-8x=9
x= -0.9
Answer:
x = 4
Step-by-step explanation:
- = 6x - - 5
Multiply through by 15 ( the LCM of 5 and 3) to clear the fractions
5(7x + 14) - 3(17 - 3x) = 90x - 5(4x + 2) - 75 ← distribute parenthesis on both sides
35x + 70 - 51 + 9x = 90x - 20x - 10 - 75 , that is
44x + 19 = 70x - 85 ( subtract 44x from both sides )
19 = 26x - 85 ( add 85 to both sides )
104 = 26x ( divide both sides by 26 )
4 = x
Answer:
when u add .1 to the 1.9
Step-by-step explanation:
X=<span><span><span><span>−4/</span>3</span>y</span>+<span><span>−8/</span><span>3
and

Volume of padding = volume of box - volume of calculator
= (14.5 x 24 x 6) - (8.5 x 18 x 2.5)
answer = 1705.50 cm^3
