Ii.First ,expand: 5(x-2)=32
5x-10=32
bring 10 to the other side (add it to 32)
5x=42
divide both sides by 5 to get x
x=42/5
x=8.4
iii.Expand 5+2(x+3)=21
5+2x+6=21
bring 5 and 6 to the other side
2x=21-5-6
2x=10 divide both sides by 2
x=5
Answer:
-4f
Step-by-step explanation:
Hi! Let's work on simplifying this.
f(4) = 4f
f(0) = 0, because anything x 0 is 0
f(-8) = -8f
Our equation is 4f + -8f
We can get rid of the plus negative...
4f - 8f
So we get:
-4f
Answer:
the answer is 4
Step-by-step explanation:130-50=80
80/20=4
Answer:
Step-by-step explanation:
The original price of the math book is
50$, The amount of money that you have with you is $35.
If you get a discount of 20%, it means that you get 20% of $50. This is expressed as
20/100 × 50 = 0.2 × 50 = $10
The new cost of the math book is determined by subtracting the discount from the original price. It becomes
50 - 10 = $40
Since the amount that you have with you is $35, the amount that you need to borrow in order to buy the math book is
40 - 35 =$5
