Answer: 
Step-by-step explanation:
By the exterior angle theorem,
A community needs to raise at least $5000 to build a new skateboarding
park. They are selling backpacks for $25 each to raise the money. Write
and solve an inequality to determine the minimum number of backpacks
they need to sell in order to reach this goal.
Answer:
2525
Step-by-step explanation:
1. Draw a block diagram to illustrate the different types of chocolate bars. (In this diagram, the creamy chocolate bars are shown as orange blocks, the milky chocolate bars as blue blocks and the white chocolate bars as red blocks.)
2. Since the number of creamy chocolate bars was 5 times the number of milky chocolate bars, we can replace one orange block (creamy) with 5 blue blocks (milky).
Since the number of white chocolate bars was 715 more than the number of milky chocolate bars, we replace one red block with one blue block + 715.
3. Looking at the block diagram, find the number of milky chocolate bars (blue block)
4250 – 715 = 3535
7 blue blocks = 3535
1 blue block = 3535 ÷ 7 = 505
The number of milky chocolate bars made was 505.
4. Calculate the number of creamy chocolate bars.
The number of creamy chocolate bars was 5 times the number of milky chocolate bars = 5 × 505 = 2525
First you need to subtract 35 to get one equation =0.
x^2-10x-10=0 then use the quadratic formula (let me know if you need the formula of need to see these steps)
and solve to = approximately 8.87 and 1.12
