Ms. Naima is 25.
(I used s for nasser and m for naima)
Set up equations.
2s - 5 = m
s + m = 40
m = 40 - s
m = m so...
40 - s = 2s - 5
Move like terms to same side
40 + 5 = 2s + s
45 = 3s
15 = s
Substitute s into an equation.
(15) + m = 40
m=40-15
m=25
since naima is represented by m, naima’s age is 25.
Answer:
Step-by-step explanation:
The hour hand is 20 mm and the minute hand is
- 200% of 20 mm = 2*20 mm = 40 mm long
The tip of the hour hand travels 1/12 of the circle and the tip of the minute hand travels full circle in one hour.
Find each length and their difference using circumference formula.
<u>Hour hand</u>
- 1/12*(2*3.14*20) = 10.47 mm (rounded)
<u>Minute hand</u>
<u>The difference between the two above</u>
- 251.2 - 10.47 = 240.73 mm
Answer:
The fully factored form is 3(x^2 - 7))
Step-by-step explanation:
The only thing you can do with this equation is take out a factor of 3. You cannot simplify the resulting parenthesis without using irrational numbers.
The last one x^4.
A: If you bring 2^-5 to the numerator which is what the - expects you to do, then you get x^5 which is 32
B: No problem here. 32 = 32
C: 2^1 * 2^4 = 2^(1 + 4) = 2^5.
C: 2^5 is 32
D: 2^4 = 16.
Answer: D does not agree with the others.
