I don't agree with his method because he should've used the distribute method for the first step. For step 2, he would've needed to add 18 on both sides. Step 3 would be for him to divide both sides by 2, not subtract 2.
Step-by-step explanation:
2(x - 9) = 10
step one: distribute
⇒ 2x - 18 = 10
step two: add 18 on both sides and then simplify
⇒ 2x - 18 + 18 = 10 + 18
⇒ 2x = 28
step three: divide both sides by 2
⇒
⇒ x = 14

SI=(P*R*T)/100
P=2000
R=1.5
T=6
SI=(2000*1.5*6)/100
=(2000*9)/100
=180
Neil will earn interest of 180
The answer is in the image
F=ma
where F=force
m=mass
a=acceleration
Here,
F=4300
a=3.3m/s2
m=F/a
=4300/3.3
=1303.03kg
Approximately it is aqual to 1300kg
Here,
tip=18%of $32
tip=(18/100)*32
=0.18*32
=$5.76
Total payment=32+5.76=$37.76
The wood before starting =12 feet
Left wood=6 feet
Wood used till now=12-6=6 feet
Picture frame built till now= 6/(3/4)
=8 pieces
Therefore, till now 8 pieces have been made.
Salesperson will make 6% of 1800
=(6/100)*1800
=108
Salesperson will make $108 in $1800 sales
30% of 420 are first year students
first year students = (30/100 )*420
=126 students
Student who are not in first year = 420-126
=294 students
It will provide an instant answer!
