Gabrielle is x years old.
Felicia is 6 years older.....so Felicia is x + 6
the mom is twice as old as felicia...so the mom is 2(x + 6)
the aunt is x years older then mom....so the aunt (tanya) is 2(x + 6) + x
so Tanya/s age is :
2(x + 6) + x =
2x + 12 + x =
13x + 12 <===
.4 is tenths .42 is hundredths and .422 is thousandths
Answer:
for 18 x is 6 and for 20 it is 11
Step-by-step explanation:
For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6
For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11
Hope this helps :)
Answer:
$7.50
Step-by-step explanation:
3 hours + 5 hours = 8 hours
8 hours = $85 (total) - $25 (allowance)
8 hours = $60 (money earned from work)
1 hour = $60 ÷ 8 (hours he worked)
1 hour = $7.50
