Answer:
994
Step-by-step explanation:
2(s+t)= 10
10^3= 1.000
1.000-6= 994
A. 20% because you paid $21 out of $105 so 21/105 =.2 and to make it a percent you move the decimal over to places, making it 20%
-2x^2-3x is how you can simplify the expression
X = 8
y = 40
the two base angles are equal to each other so you would do 5x = 40 and solve for x
a triangle has 180 total degrees. 40*2 = 80
180 - 80 = 100
2y + 20 = 100
2y = 80
y = 40
