1) 30% - 212.52/(427.25+212.52+75)
2) 893.59
Total amount spent on Flooring (427.25+212.52+75) = 714.87
Amount spent on furniture = 714.87 * 1.25= 893.59
3) 13%
(893.59-558.49-893.59/4)/893.59
X=cost of large snack
Y=cost of small snack
X+Y=60
5X+3Y=220
To solve for y, solve x+y=60 for x. Subtract y from both sides so you're left with x=-y+60. You now plug in -y+60 for x in the second equation.
5(-y+60)+3y=220
-5y+300+3y=220
-2y+300=220
-2y=-80
Y=40
40 small snack packs is the final answer
Step-by-step explanation:
angle A = 38
now come with me inside the triangle ABC
use two property of isoceles traingle and sum of angles of triangle
you get x= 71°
3ˣ (x² - 3)
Basically, just multiply everything together.
Step 1 : 3x × x² = 3x³ because when multiplying exponents, all you're really doing is adding them on top. So, x + 2x = 3x! But, they are exponents, so you get 3x³.
Step 2 : 3x ˣ × (-3) = -9ˣ
Now, our new question is : 3x³ - 9x
You wouldn't simplify this because x³ is NOT the same as x.
