Answer:
x = 8
Step-by-step explanation:
The diagram shows two similar triangles. Similar triangles have all the same angles and the sides are proportional to one another. So, by setting up a proportion of the sides, you can solve for the missing variable:
Cross-multiply: 72(14x + 5) = 156(54)
Distribute: 1008x + 360 = 8424
Subtract 360 from both sides: 1008x + 360 - 360 = 8424 - 360
Divide: 1008x/1008 = 8064/1008
Solve for x: x = 8

Answer:$7.50
Step-by-step explanation: make 4 boxes on a paper and put two lines in each box and you see that it is 8 in the boxes all to heather so that equals $8.00 so you can’t put a dollar in each box because if you do it will equal twelve dollars and you have to make ten dollars so you put $0.50 in each box so in each box it will be $2.50 in each box so you have to add $2.50 for times so it equals $10.00 so I added it it does add up to ten dollars so to see how much 3 bottles of water count you have to add up $2.50 3 timer and it equal $7.50
If the "break apart stradegy" is the same as what I was taught, you would add the ones place, the tens place, the hundreds place, and so on. This would be 7 + 8 then 40 + 50 and then 200 + 300. Add what you got together. So 247 + 358. You would get 605.
