5/3x = ? ; where x = 90
90/1 times 5/3
cross simplification
now it's 30/1 times 5/1 i divided the numerator of the first fraction and the denominator of the second fraction by 3
now it is 5 times 30
so... 5/3 of a 90 degree angle is 150 degrees
Answer:
C.) y/2
Step-by-step explanation:
We can simplify (x+3)/3 to x/3 + 3/3, then simplify (y+2)/2 to y + 2/2, and since 2/2 and 3/3 are both 1, so we can say that x/3 + 1 = y/2 + 1, meaning that x/3 = y/2.
Answer:
Jane scored 28 and Lenny scored 7
Step-by-step explanation:
x^6
When multiplying numbers in exponential form, if the number is the same, you can simply add the exponents:
x^2 * x^4 = x^(2+4) = x^6
Use equation C1M1+C2M2=CM
C1=15%, M1=10000 mg (starting ointment)
C2=0% M2=to be found (diluent)
C=12% M=M1+M2 (product)
Solve for M2
0.15*10000+0*M2 = 0.12(10000+M2)
M2=(0.15-0.12)*10000/0.12=2500 mg
Answer: 2500 mg of diluent is required.
