(7+x)+x=15
I did trial and error to get x=4.
Answer:
$10.80 (about $11)
<em>Brainliest, please!</em>
Step-by-step explanation:
20% = 0.2
+20% = x 1.2
1.5 x 1.2 = 1.8
1.8 x 6 = 10.8
Answer:
40mph
Step-by-step explanation:
Using D = rt, the current variables we have are
D = 20 miles
t = 30 minutes
Since the goal is rate, we alter the equation to r = D/t.
In addition, we have to convert minutes into hours so we can
r = (20 / 30)*2/2
r = (40/60)
60 minutes is converted into an hour so the rate <em>r</em> is 40 miles per hour.
r = 40/1
M^2 + 12m + 35
Factored:
(m+5)(m+7)
Check:
(m+5)(m+7)
(m*m) + (m*7) + (5*m) + (5*7)
m^2 + 12m + 35
Hope this helps! :)
