Answer:
13
Step-by-step explanation:
25 x 2 = 50. 10% of 70 equals 7. 50 + 7 = 57. 70 - 57 = 13.
9.2 could represent the lengh of teds pencil because it is larger than 8.5 which is jans pencil
-2x-7=3
or,-2x=10
or,x=-5
Since we`ve got the value of x.let`s substitute it in 9x-7
=9×(-5)-7
=-52
You subtract 2 on each side. so then it will be 2x=2. then you divide each side by 2 to get x=1.
hope this helped!
