Answer:20%
Step-by-step explanation:Based on the given conditions, formulate:( 35 - 28 ) divided by 35
Calculate the sum or difference: 7/ 35
Cross out the common factor: 1/5
Multiply a number to both the numerator and the denominator: 1/5 x 20/20
Write as a single fraction: 20/5x20
Calculate the product or quotient:20/100
Divide the sale price by the original price:
56 / 89 = 0.7
Multiply by 100:
0.7 x 100 = 70%
The sale price is 70% of the original price, so the discount would be 30% (100-70= 30)
Answer:
21 degrees
Step-by-step explanation:
Triangles have a total angle of 180 degrees.
This makes our equation:
3x+3+4x+135=180
Subtract 135 from both sides and combine like terms
7x + 3 = 45
Subtract 3 from both sides
7x = 42
Divide both sides by 7
x = 6
Plugging the number in:
3x + 3 =
3(6) + 3 =
21
