15,518, because it is over 15,500 and below 16,499.999999...
A+B=15 —>A+15=B(plug this into the other equation)
60a+30b=600
60a+30(a+15)=600
60a+30a+150=600
90a+150=600
90a=450
A=5 (plug back in to first equation)
A+B=15
5+B=15
B=10
They have 5 of the Model A and 10 of model B.
Answer:
Step-by-step explanation:
4.0 | <u> 4.50 </u> | -0.3(4.0) + 6.71 = <u>5.51</u> | 4.50 - 5.51 = <u>-1.01</u>
5.9 | <u> 5.50 </u> | -0.3(5.9) + 6.71 = <u>4.94</u> | 5.50 - 4.94 = <u>0.56</u>
Negative infinity to positive infinity
Answer:
Step-by-step explanation:
