(a)

different possibilities
(b)


So, there is a 1 in 4 chance that both dice will show an even.
2(4x-3)-7(x+1) first distribute
8x-6-7x+7 then combine the x's
<u>x+13 </u>
<span>3x=4y=7z
so
GCF:
3 * 4 * 7 = 84
3x = 84
x = 28
4y = 84
y = 21
7z = 84
z = 12
</span><span>least possible value for
</span><span>x + y + z = 28 + 21 + 12 = 61
</span>
answer
(d) 61
<span>Twice a number is equal to negative four :
2n = -4
answer
</span><span>2n = -4
last one is your answer</span>
