Answer: the ordered pair is (-14,-6)
Step by step:
x – 2y = -2 (Eq. 1)
x – 4y = 10 (Eq. 2)
Isolate x in Eq. 2:
x = -2 + 2y
Substitute that solution x in Eq. 2:
x - 4y = 10
-2 + 2y - 4y = 10
Solve for y:
-2 - 2y = 10
-2y = 10 + 2 = 12
y = -6
Then calculate value for x using the above value for y
x = -2 + 2y
x = -2 + 2(-6) = -14
The solution is (x,y)=(-14,-6)
Answer:
180 - 61 = 119
Step-by-step explanation:
So from A to D it is 180 degrees so just have to subtract 61 from 180 for an answer.
Answer:
368 cans.
Step-by-step explanation:
Volume of 1 can = π r^2 h.
Here h (height) = 12 and r (radius) = 1/2 * 6 = 3 cm.
So V = π * 3^2 * 12
= 108π cm^3.
The tank hold 125 liters
= 125,000 cm^3, so:
Number of cans that could be filled = 125000/ 108 π
= 368.4.
