Answer:
x < -9
Step-by-step explanation:
Hi there,
To isolate the variable x, you do the same steps like solving a regular equation.
x + 5 < -4 ← subtract 5 from both sides to make x by itself
x < -9 ← final answer (already in simplest form)
Hope this explanation helps. Cheers.
Answer:
B.The exponent of the solution is –12, the difference of the original exponents.
C.The coefficient of the solution must be greater than or equal to one but less than 10.

Answer:
9x + 17
Step-by-step explanation:
(3x - 1) + (4x + 7) + (2x + 11)
= 3x - 1 + 4x + 7 + 2x + 11
= 3x + 4x + 2x - 1 + 7 +11
= 9x + 17
Answer:
97.53 in³
Step-by-step explanation:
The cylindrical birthday cake has a diameter (d) of 14 inches and a height (h) of 6 inches.
The radius of the cake (r) = diameter / 2 = 14 inches / 2 = 7 inches.
The volume of the full cake = πr²h = π(7²)6 = 924 in³
Since only a part of the cake was cut and given to Myong. The total measure of the cake is 360°, but the part given to her was 38°. Hence the volume of her slice is given as:
Volume of her slice = (38 / 360) * volume of the full cake = (38 / 360) * 924 = 97.53 in³
Volume of her slice = 97.53 in³
To put words into equations:
x+y+z =50
x=4y
4y=5z -> z= 4/5 y
Which means
4y+y+ 4/5 y= 50
29/5 y =50
29y=250
Y=29/250
