Answer:
x >2
Step-by-step explanation:
x/2 +3 > 4
Subtract 3 from each side
x/2 +3-3 > 4-3
x/2 >1
Multiply each side by 2
x/2*2 >1*2
x >2
Answer: There are 24 pieces of silverware in all.
Step-by-step explanation:
3+ 7 + 14 = 24
3 forks
There are 4 more knives than forks - 7 knives
There are twice as many spoons as knives - 7.2 = 14
Explanation:
All of these are done the same way.
1. Set your compass to a distance slightly longer than the distance from the point to the line you want the perpendicular to.
2. Using the point as a center, draw an arc that intersects the line in 2 places. Consider those points to be "P" and "Q".
3. You can leave the compass as is, or set it to any other distance longer than half the distance between P and Q. Using this radius, and using P and Q as centers, draw intersecting arcs on the other side of the line from the original point. Consider the intersection of those arcs to be point "R".
4. A line through the original point and point R will be perpendicular to the line, as you want.
_____
In problem 1, the point and line are obvious.
In problem 2, the point is the vertex opposite the line of interest. (There will be 3 similar constructions.)
Ignore the second fraction for a moment. say Jackson eats 1/4 of a banana every serving. how many servings would it take to eat the whole banana? 4, of course, because 4 1/4's equals one. now say that each serving is the same as 1/2 minute. Just multiply 1/2 minute by the 4 servings. 2 full minutes.
