The number can be written as 4 tens 2 ones is 42
For a problem like this, you'll want to break it down ...
Total cost = $19.60.
Cost of beads = $12.80.
Cost of pendant = ?
We know that there are 4 necklaces. Each necklace has one pendant, so we have 5 pendants total. Therefore, your solution should look something like this ...
Total cost = Cost of beads - cost of pendant
$19.60 = 12.80 - 4x <- x is the variable representing the price for a single pendant.
6.80 = 4x <- Subtract 12.80 from both sides.
x = 1.70 <- Divide both sides by 4, and find your final answer.
x = 1.70; therfore, each pendant costs $1.70.
Answer:
Yes a third plane can be drawn which contains parallel lines.
Step-by-step explanation:
There are two points:
1) a third plane can cab drawn which can have two line parallel as shown in the figure 1.
2) If plane A has a line and plane B has a line such that they are parallel to each other than the third plane cannot be drawn which contains both lines and b parallel.
A third plane can have only two lines parallel if they are not parallel in the in the other two planes.
We see that lines c and d parallel in the third plane are perpendicular in the planes A an d B.
Answer:
7times 6<9 times 5
Step-by-step explanation:
7 times 6 is 42 and 9 times 5 is 45 so nine times five is larger
