Answer:
A. x = -7, B. x = -8, C. x = 9, D. x = 2, E. x = -3
Step-by-step explanation:
A. 4x= -28
Divide both sides by 4.
=
. x= -7
B. x- -6= -2 -> x+6= -2
Subtraction 6 to both sides.
x- +6-6= -2-6, x= -8
C. -x+= -9 -> x= 9
D. -3x+7=1
Subtraction 7 to both sides.
-3x+7-7 =1-7 , -3x=-6
Divide both sides by -3.
= 
, x= 2
E. 25x+-11= -86 -> 25x-11= -86
Add 11 to both sides.
25x-11+11= -86+11, 25x= -75
Divide both sides by 25.
= 
, x= -3
2. 2x+9= -15
Subtraction 9 to both sides.
2x+9-9= -15-9, 2x= -24
Divide both sides by 2.
= 
, x= 12
I don't think there's an answer.
I hope it helps you!
Answer: 36
Step-by-step explanation:
The 100% of the sweater is 45, we multiply 45 per 20 divided by 100, that will give you 9, you want to rest 45-20%
45-9=36
Answer:
The percentage loss = 10.9375 %
Step-by-step explanation:
Let the cost price = x
Since the marked price is 18.75% above the cost price so the
Marked price = 1.1875 x
When a discount of 25% is allowed on the marked price , the selling price will be Rs. 1425
⇒ Marked price × 0.75 = 1425
⇒ Cost price × ( 1.1875 × 0.75 ) = 1425
⇒ Cost price × ( 0.890625 ) = 1425
⇒ Cost price = 1600
Selling price = 1425
So percentage loss = × 100
% Loss = × 100
% Loss = 10.9375 %
For this question you should know that you can multiply both number in 1/4 by 3 and you will have:
1*3 / 4*3 = 3/12
so the answer is yes they are equivalent :)))
i hope this is helpful
have a nice day
