-4(7a+5)= —160
distribute the -4 on the left hand side
-4* 7a + -4*5 = -160
-28a +-20 = 160
-28a -20 = -160
add 20 to each side
-28a-20+20 = -160 +20
-28a = -140
divide by -28 on each side
-28a/-28 = -140/-28
a = 5
Answer: a=5
Answer: (a) 9
<u>Step-by-step explanation:</u>
1st multiple of 3: 1(3x)
2nd multiple of 3: 2(3x)
3rd multiple of 3: 3(3x)
Sum = 4(1st multiple of 3) + 6
1(3x) + 2(3x) + 3(3x) = 4(3x) + 6
3x + 6x + 9x = 12x + 6
18x = 12x + 6
6x = 6
x = 1
Largest (3rd) multiple is: 3(3x)
= 9x
= 9 · 1
= 9
