Answer:
The answer is 18
Step-by-step explanation:
1.5(p+n) for p= and n =6
As we know the values of p=6 and n=6
Solve it according to the BODMAS rule. According to this rule if we have brackets or parenthesis then first we have to solve or simplify the brackets.
Put the values in the given expression:
1.5(6+6)
Now solve the parenthesis first:
1.5(12)
Now multiply 1.5 by
The answer is 18....
1
It's whole number
So I think it's the answer

<span><span>time she spent walking = T
</span><span>
</span></span>
time she spent jogging = 1.2 - T
<span>
<span>
</span></span>
<span><span>2T + 4(1.2 - T) = 3.4
</span><span>
</span></span>
<span><span>2T + 4.8 - 4T = 3.4
</span><span>
</span></span>
<span><span>2T - 4T = 3.4 - 4.8
</span><span>
</span></span>
- 2T = - 1.4
T = -1.4—2 = 0.7 hours = 42 minutes
Time she spent jogging = 1.2-0.7 = 0.5 hours = 30 minutes
2.
Against wind :2400 miles in 10 hours
With wind : 2400 miles in 8 hours
Speed of plane = x
Speed of wind = y
t=d/r
against the wind speed x-y mph
with the wind x=y mph
2400/(x-y)=10
2400 = 10x-10y
240 =x-y eq.1
2400/x+y=8
2400 = 8x+8y
300 = x+y eq 2
Add eq1 & eq 2 = 740 = 2x
X = 740/2 = 370 mph for plane
300 = 370 +y
Y = 370-300 = 70 mph wind speed
2/15 is the correct answer
Answer:
3/4
18/24
Explanation:
9/12 in simplest for is 3/4
9/12 times 2=18/24
