Answer:
angle C = 36°
Step-by-step explanation:
Fun fact that I found out:
all interior angles of a triangle added together = 180°
5x + 3x + 2x = 180°
combine like terms:
10x = 180°
divide both sides of the equation by 10:
x = 18°
angle C = 2(18°) = 36°
Answer:
y=2
Step-by-step explanation:
(y+7)÷3=3y-3
y+7=9y-9
7+9=9y-y
16=8y
2=y
Answer:
The sale price of the item is $
255
Step-by-step explanation:
To determine the amount of discount (
d
) offered by the store, we calculate
15
% of the sale price. Thus:
d = 300 × 15
÷ 100
d = 3
00 × 15 ÷ 1
00 (take the 2 zeros out on both the hundred and 3 hundred)
d = 3 × 15
d = 45
If the amount of discount is known, the sale price (
s
) of the item will be the regular price minus the discount. Hence:
s = 300 − 45
s = 255
Hope this helps you! If not sorry!
Answer:
The value would be
Step-by-step explanation:
What is the value of x in: 4x+3y=12 and 2x-3y=-30 *
4x + 3y
The answer is x = 2 - 3y = 4
3y = 30
So 2x + 3y = 12 is
X = 3 - 3y/4
2x - 3y = 30
X = 15 + 3y/2
