I'm confused, it shows y at a right angle = 90°
we can solve for x
(x-7) and (x-3) = x=7
Set the smaller one to x. 2x+6=22, so 2x=16. Thus, x=8 and x+6=14, so 8 and 14 are our numbers.
I need a little more to work with
Given:
Entrance fee per student: $5(29)
Lunch costs: $4(29 + 6)
Bus fees: $25 + 8($2 + $3)
Total cost: 5(29) + 4(35) + 25 + 8(5)
To find:
The equivalent expressions of the total cost that use the properties of operations to simplify the math.
Solution:
We have,
Total cost = 5(29) + 4(35) + 25 + 8(5)
To simply this expression, we need to write 29 and 35 in the expand form or as the sum of their place values because it is easy to multiply a number with multiply of 10 and single digit.
Total cost = 5(20+9) + 4(30+5) + 25 + 40
Therefore, the correct option is B.
Answer:
do the work on your calculator to double check yourself :)
