Step-by-step explanation:
y>= x -2 is easy to see but x + 2y <4 is easier to see if rewritten in slope-intercept form:
y< -1/2x +2
Answer:
864 sq. in.
Step-by-step explanation:
The figure is a cube
The surface area of a cube is equal to
S= 6b^2
where
b is the length side of the cube
In this problem we have
b=12 in.
substitute
S=6(12)^2 = 864 sq. in.
You use subtraction in this operation:
70 seashells - 19 seashells = 51 seashells
Thus, Joan is given 51 seashells.
Answer: 6 3/4
Step-by-step explanation:
1. Use proportion:
8:4.5=24:x
8x=24*4.5
x=3*4.5
x=13.5
2. Use proportion
8:4.5=4:x
x8=18
x=18/8
x=9/4
x=2.25
3. For 24 people you need 13,5
for 12 people you need :
24:13.5=12:x
x=13.5/2
x=6.75
