Answer:
option 4
Step-by-step explanation:
Solving the inequality
4.5 + 1.2x ≥ 10 - x ( add x to both sides )
4.5 + 2.2x ≥ 10 ( subtract 4.5 from both sides )
2.2x ≥ 5.5 ( divide both sides by 2.2 )
x ≥ 2.5
3, 4, 5, 6 are all greater than 2.5, thus
All values in the set make the inequality true
Step-by-step explanation:
Let the number of children that swam be A
Let the number of adults that swam be B
1.75A+2B=1113.75 Equation 1
Total number of people that used that pool =602
A+B=602 Equation 2
These are simultaneous Equations
multiply Equation 2 by(2) on both the sides we get
2A+2B=1204 Equation 3
Subtract Equation 1 from Equation 3
2A+2B=1204 Equation 3
1.75A+2b=1113.75 Equation 1
<u> - - -</u>
.25A+0 =90.25
.25A=90.25
A=90.25/.25
A=361
putting value of A in Equation 2 we get
361+B=602
B=602-361
B=241
so number of children is 361
and number of adults is 241
