Answer:
d
Step-by-step explanation:
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:
(-1,-1)
Step-by-step explanation:
Midpoint equation: 
= 
= 
=(-1,-1)
Use the formula and plug it in :)
Just plot the points on the graph.
2. You know since the graph is a straight line, the ratios are proportional and therefore equivalent
1) I put them in two separate brakets.
2) I solved it by equating both of them.
