To find your answer you must substitute y for 0.8
4x + (8)(0.8) = 40
Now solve for x
====================================================================
SOLVING...
<span>4x + (8)(0.8) = 40
</span><span>4x + 6.4 </span>= <span>40
</span>
Subtract 6.4 from each side
<span><span><span>4x</span>+ 6.4 </span>− 6.4 </span>= <span>40 − <span>6.4
</span></span>4x = 33.6
Divide each side by 4
4x ÷ 4 = 33.6 ÷ 4
x = 8.4
D)
6 5/8
or 6.625
Basically
1/8*3 =0.375
1/4 * 3 =0.75
1/2*5 =2.5
and 3/4*4=3
So then,
0.375+0.75+2.5+3=6.625 or 6 5/8 in fraction!
20-16 get four then u woukd have to subtract it ant the answer is 4
