5 plus 6 = 11 and their is your answer
Hi there!
if the corresponding sides are equal the 2 triangles are congruent ( by SSS) so their areas are the same.
So area of triangle DEF = 4 sq units
<span> (−3,5) and (2,−3)
slope = (5+3)/(-3-2) = -8/5
equation
y -5 = -8/5(x + 3)</span>
So he has to sell it at 19.5+2=21.5 dollars
so assume19.5=100%
the markup is 2 dollars
2=x%
find x if 19.5=100%
so since they are proportionite
19.5:100 and 2:x
if we make them fractions and flip one of them then multiply we will get 1 since
2/4=1/2
2/4 times 2/1=4/4=1 so
19.5/100 times x/2=19.5x/200=1
19.5x/200=1
multiply both sides by 200
19.5x=200
divide both sdies by 19.5
x=10.256 aprox
x=10.3% markup
Answer:
16
Step-by-step explanation:
3x+3+3x+3+5x+7+4x-1+4x-1=106
19x+11=106
19x=95
x=5
JL=5(5)+7=32
ST=1/2 of JL = 1/2 of 32 = 16
