Keiko, Chang, and Abdul sent a total of 109 text messages over their cell phones during the weekend. Keiko sent 7 fewer messages

lbvjy [14]

9514 1404 393

Answer:

Keiko: 17
Chang: 24
Abdul: 68

Step-by-step explanation:

Let c represent the number of messages sent by Chang. Then Keiko sent (c-7) messages, and Abdul sent 4(c-7) messages. The total number sent was ...

c + (c -7) +4(c -7) = 109

6c -35 = 109 . . . . . . . . . . simplify

6c = 144 . . . . . . . . . . . add 35

c = 24 . . . . . . . . . . . divide by 6

c-7 = 17

4(c-7) = 68

Keiko sent 17, Chang sent 24, and Abdul sent 68 text messages.

= 98 - 40 $\sqrt{6}$

Step-by-step explanation:

i) (5 $\sqrt{2}$ - 4 $\sqrt{3}$ ) × (5√2 - 4√3)

=(5 $\sqrt{2}$ × 5 $\sqrt{2}$ ) - (5 $\sqrt{2}$ × 4 $\sqrt{3}$ ) - (4 $\sqrt{3}$ × 5 $\sqrt{2}$ ) + (4 $\sqrt{3}$ × 4 $\sqrt{3}$ )

= 50 - 20 $\sqrt{6}$ - 20 $\sqrt{6}$ + 48

= 98 - 40 $\sqrt{6}$
