For this specific problem, this would be the solution:
<span><span>= 0.7(133) + 0.8(133) - 2(0.4[133]) </span><span>
<span>= 93 +
106 - 2(53) </span>
<span>= 199 -
106 </span>
<span>= 93 </span></span></span>
This means 93 students passed in both the subjects. I am hoping that
this answer has satisfied your query about and it will be able to help you.
Answer:
3
Step-by-step explanation:
Step 1:
- 5x + 2 = - 13 Equation
Step 2:
- 5x = - 15 Subtract 2 on both sides
Step 3:
x = - 15 ÷ - 5 Divide
Answer:
x = 3

Answer:
x = π/6, π/2, 5π/6, 3π/2
Step-by-step explanation:
cos x = sin(2x)
Use double angle formula.
cos x = 2 sin x cos x
Move everything to one side and factor.
cos x − 2 sin x cos x = 0
cos x (1 − 2 sin x) = 0
Set each factor to 0 and solve.
cos x = 0
x = π/2, 3π/2
1 − 2 sin x = 0
sin x = 1/2
x = π/6, 5π/6
The total solution is:
x = π/6, π/2, 5π/6, 3π/2
Answer:
2x-106
Step-by-step explanation:
-7(x+10)+9(x-4)
Expand parentheses:
-7x-70+9x-36
Combine like terms:
2x-106
