Answer:
His rate of change is 7 pounds per week.
Step-by-step explanation:
Rate of change = change in weight ÷ change in time
change in weight = 188 - 167 = 21 pounds
change in time = 6 - 3 = 3 weeks
Rate of change = 21 ÷ 3 = 7 pounds/week
Step-by-step explanation:
1) Perimeter = 2(l + w)
Perimeter = 2(94 + 64)
Perimeter= 2(158) = 361 cm
2) Fabric required = Area
Area = l × b
Area = 94 × 64
Area = 6016 cm²
2(x+2)=3(x-3)
2x+4=3x-9
2x=3x-13
-x=-13
x=13
The number is 13
