Answer:
15pages
Step-by-step explanation:
there are 75 pages on her book
lilla read 1/5 of her book last week=1/5*75=15pages
this week she read 3times as much as she read last week=3*15=45pages
pages left to readcan be given as;
75-(15+45)
75-60= 15pages
X = number of weeks
1 week =
3x = $90
Divide by 3
3x/3 = x
$90/3 = $30
1 person = $30 per week
x 5
5 people = $150 per week
x6
6 people = $180 per week

now, the x-axis has years after 1987, so 2007 is 20 years after 1987, 1987 + 20 = 2007, therefore x = 20, what is y?............
.
and you know how much that is.
Answer:
The sandbox is most likely in the shape of a kite. As it has only two right angles, it cannot be a square or other form of rectangle. It also cannot be a parallelogram, which has no right angles, nor is it a rhombus- all four sides are not of the same length.
A kite, however, has two pairs of equal-length sides that are adjacent to each other. It also has two sets of equal-measure angles, one of which can be 90° if it is a cyclic kite.
