Answer:
(x,y)=(3/2, -1/2)
Step-by-step explanation:
2x+4y=1 /*3
3x-5y=7 /*(-2)
6x+12y=3
-6x+10y=-14
...........................
/ 22y=-11
y= -11/22
y= -1/2
2x+4*(-1/2)=1
2x-2=1
+2 +2
2x=3
x=3/2
so the solutionis (x,y)=(3/2, -1/2)
Answer:
you predict
Step-by-step explanation:
i just took it
The volume of any "pointy" solid will be 1/3 that of the corresponding prism or cylinder (with same height and base area). The only caveat is that the slope of the sides of the pointy solid is constant.
For your figures: 1/3.
Answer:
Step-by-step explanation:
Step 1. Switch sides.
Step 2. Since the fraction 1/2 multiplies b, multiply both sides by the reciprocal of 1/2 which is 2.
Step 3. Since h is multiplying b, and you want b alone, divide both sides by h.
