First, determine what 15% of $40 is.
Convert 15% to a decimal: 0.15
Then multiply this decimal by $40: 0.15 x 40 = 6
So the discount is $6.
We subtract the discount from original price to get sale price.
40-6= 34
So the item will cost $34.
Four apples.
Fifty percent - or half - of eight is four
Answer:
a. The variable X represents the amount of hot dogs
b. the variable Y represents the amount of sodas
c. Their total expense would be $13.50
If you multiply $1.50 by 7 you would get $10.50, then you would multiply $0.75 by 4 and get $3.00.
then you would add 10.50 and 3.00 to get $13.50
First, square the entire problem. Then add the n's and subtract 10 from 5. You will then get 2n-5=0. Add 5 to both sides, then divide by two to get the answer. (2n=5, n=2.5)
Answer: Yes! those are indeed apart of the fact family
Step-by-step explanation:
Notice that 9+5=14 and 5+9=14, thus the first two equations
show that if we add two numbers in any order, we get the same answer.
Notice that 14-9=5 and 9+5=14, so subtraction and addition are
related. Similarly 14-5=9 and 5+9=14
Notice that 14-9=5 and 14-5=9, so if you subtract one of the
members of the fact family from 14, you get the other.
