7x+5y= 19
-7x-2y=-16 add because its a negative
-----------------
3y=3
y=1
then you find x by placing 1 for y
7x+5(1)=19
7x=14
x=2
(2,1)
M1+m2+m3=180
m5+m6+m7=180
Triangle angle sum theorem
m1+m2+m3=m5+m6+m7
Since m3 is congruent to m5
You can subtract m3 from the left and m5 from the right
m1+m2=m6+m7

Answer:
200
Step-by-step explanation:
If 40% are roses than 60% must be sunflowers (40% + 60% = 100%)
We are trying to find 60% of some number is 120.
Let n = the total number of flowers
.6n = 120 Divide both sides by .6
n = 200
