Answer:
x=10
Step-by-step explanation:
first substitute y with the value (-5)
2x+5(-5)=-5 which is simplified to 2x+-25=-5
add 25 to -5 which gives you 2x=20
then divide 20 by 2 which makes x=10
<span>2^x+4 -12=20
</span><span>2^x+4 = 20+12
</span><span>2^x+4 = 32
</span><span>2^x+4 = 2^5
x+4 = 5
x = 1
answer is </span><span>B. x=1</span>
Answer:
in this case, x is the amount more he needs to save per month
350=12(x+20)
distribute
350=12x+240
minus 240 both sides
110=12x
divide both sides by 12
9.166666=x
needs to save about $9.17 more per month or 29.17 permonth
