Answer:
its suposed to be written [(40+5)-3^2]÷9·2
so the answer would be C.8
Step-by-step explanation:
first do whats in the brackets but inside the ark looking brackets first
[(40+5)-3^2]÷9·2
will be [45-3^2]÷9·2
and then you do the rest of the brackets but first you square 3 sitch will be come 9
so [45-9]÷9·2
witch will become
36÷9·2
now divide by 9 and get
4·2
witch is going to be
8
therefore the answer is C.8
if brainiest is earned then its greatly appreciated. have a wonderful day
Correct Answer are A and D
You need k by itself, so the only way to do that is to divide both sides by 5
Q + n = 91
q +n -n =91-n
q= 91-n
.25q +.05n = $14.55
.25(91-n)+.05n = $14.55
22.75-.25n+ .05n= $14.55
22.75 -.20n =14.55
22.75-22.75-.20n=14.55-22.75
-.20n=-8.2
-.20n/-.20n= -8.2/-.20n
n= 41
q + 41 = 91
q +41 -41 = 91-41
q = 50
CHECK
.25(50) + 0.05(41) = $14.55
12.50 + 2.05 = $14.55
$14.55 = $14.55
