7) x= men
x+6= women
x + (x+6)= 30
2x + 6= 30
2x= 24
x= 12
x+6= 18
8) x= first integer
x+1= second integer
x+2= third integer
x + (x+1) + (x+2)= 153
3x + 3= 153
3x= 150
x= 50
Second integer
= x+1
= x+50
= 51
9) x= first integer
x+2= second integer
x+4= third integer
x + (x+2) + (x+4)= 54
3x + 6= 54
3x= 48
x= 16
x + (x+2)= 34
16 + 16 + 2= 34
34=34
10) rate= 356 km/hr
distance= 1424 km
Distance= rate * time
D= rt
1424= 356 * t
divide both sides by 356
4 hrs= t

Answer:
63% of students
Step-by-step explanation:
Z = (X - μ) / σ
Z = 520 - 500 / 60
Z = 0.33
ON THE Z-TABLE
0.33 = 0.6293
<em>62.93% = 63% of students answer</em>
Well brake 7 into 5 and 2 and then just multiply it by 3 so it would be 5 x3=15 and 2x3=6 then u add 15+6 it would be the sum, of 21 so 3x7=21
Answer:
1.) $1.07
2.) $2.25
3.) $14.20
Step-by-step explanation:
