<span>a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.</span>
Answer:
Step-by-step explanation:
What we know is that A + S = 111. That is, the miles Andre drove plus the miles Scott drove totalled 111 miles. What we also know is that Scott drove quite a bit more than Andre did. Scott drove 7 miles more that ( +7 ) 3 times the number of miles Andrea drove. That looks like this algebraically:
S = 3A + 7
Now we can sub in that value for S to the original equation:
If A + S = 111 and S = 3A + 7, then
A + 3A + 7 = 111 and
4A + 7 = 111 and
4A = 104 so
A = 26 and
S = 3(26) + 7 so
S = 85 miles.
Scott drove 85 miles.

Answer:
x = 28/3
Step-by-step explanation:
We can solve this problem by using similar triangles:
Both of these triangles have a 90 degree angle and they share angle A, meaning that they are similar by AA similarity.
Now we can set up ratios and solve:
13/7 = (x+8)/x
multiply both sides by x:
13x/7 = x+8
Multiply both sides by 7:
13x = 7x + 56
move the 7x over and divide by 6:
6x = 56
x = 28/3
