Answer:
x = - 8
3x - 2y = 18 is the same as 3x - (2x - 13 times 2) = 18
Then I used an algebra site for the rest.
It should be x = - 8
volume of the center sphere = 4/3*PI*r^3
r = 3 ( given in the picture)
so 4/3 * 3.14 *3^3 = 113.04 cubic feet
volume of 1 cone: pi *r^2 *h/3
r = 3 and h=3 ( given in the picture)
so 3.14 * 3^2 * 3/3 = 28.26 cubic feet
there are 4 cones so 28.26* 4 = 113.04 cubic feet
113.04 + 113.04 = 226.08 cubic feet
rounded to nearest cubic foot = 226 cubic feet
Answer:
y=-2x-3
Step-by-step explanation:
4x+2y=-6
2y=-6-4x
y=-6/2-4/2x
y=-3-2x
y=-2x-3
Answer:
45
Step-by-step explanation:
Subtract $34.99 from $40 to figure out how much money you have left for text messages.
You have $5.01 left and you divide that by $0.11 (cost for each text). Your answer is 45.5454. Since you can’t send 1/2 a text, your answer is 45.
