Answer: 23(1/4)
Step-by-step explanation: this is the answer you can star resolving the equation into the parenthesis
(3/6)² + 7 *4 - 5
if we elevate to the power of 2 the values into the parenthesis, we get the following equation.
(9/36) + 7*4 -5
after this we follow with the values into the parenthesis, if you divide 9 over 36 we get the following result
9/36 = 0.25
then we get the following equation
0.25 +7*4 - 5
after that we can resolve the multiplication getting the following equation
0.25 +28 - 5
then if we resolve the subtraction, we will get this result.
28-5 = 23
then we have 0.25 + 23 this equation is equal to 23.25
if you follow the answer will be one with 23, then we get the possible results, if you divide 1/4=0.25
then we get that the result is
23(1/4)
Add 13 to both sides
13 = 2x + 15x
Simplify right side
13 = 17x
Divide through by 17
13/17 = x
Answer:
77
Step-by-step explanation:
percentage Students
78%-------------- -273
100%-------------- ---X
(100x273)/78 = 350 students in class so
how many did not pass?
350-273 = 77 students not pass
