Because of the rules for sequence of operations, multiplication is done before addition or subtraction.
3-(3*6)+2
= 3-18+2
=-13
Answer:
56
Step-by-step explanation:
Let the angle be " x ".
Complement of the angle = ( x - 22 )
To find : x = ?
x + x - 22 = 90
2x - 22 = 90
2x = 90 + 22
2x = 112
x = 112 / 2
x = 56
Therefore, the angle is 56.
Multiply 15%*9.99=1.4985 this is the discount.
If you substract 9.99-1.4985= $8.4915 this is the sale price.
Answer:
ST = 15 cm
Step-by-step explanation:
find BC first by adding four other sides and subtracting from 36.8
sum of 4 sides is 30.8, so BC = 6
Now find ST by creating a proportion from corresponding sides:
BC / ST = DE / UV
6 / ST = 13.2 / 33
Cross-multiply:
13.2ST = 198
ST = 198/13.2
ST = 15
