$1.54
Step-by-step explanation:
18% of $15.85 is 2.853, so your total is $18.703
20% of $14.30 is 2.86, so their total is $17.16
So the difference is $1.543, rounded (since your dealing with money) would be $1.54
Answer:
x = 3
Step-by-step explanation:
Since the triangles are congruent then corresponding sides are equal, thus
x - y = x + 2 ( subtract x from both sides )
- y = 2 ( multiply both sides by - 1 )
y = - 2
and
4x + 2y = 2x - y
substitute y = - 2
4x - 4 = 2x + 2 ( subtract 2x from both sides )
2x - 4 = 2 ( add 4 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
8 x 45 = 8(40 + 5) = 320 + 40 = 360
