Answer:
y=20
Step-by-step explanation:
25+15=40
2y=40
40/2=20
y=20
Answer:
y = 20
Step-by-step explanation:
25=2y - 15
2y - 15 = 25
2y - 15 + 15 = 25 + 15
2y = 40
2y ÷ 2 = 40 ÷ 2
y = 20
__________________________
2y - 15 = 25
2(20) - 15 = 25
40 - 15 = 25
25 = 25

Answer:
W = 8.2 cm
Step-by-step explanation:
The perimeter formula is P = 2W + 2L and here the perimeter is 65.6 cm.
Thus, 65.6 cm = 2W + 2L. Substituting 3W for L, we get
65.6 cm = 2W + 2(3W) = 8W.
Solving for W by dividing both sides by 8, we get W = 65.6 cm / 8, or
W = 8.2 cm

How much space is inside the steps?
Answer:
The answer is 0.045
Step-by-step explanation:
1. Use this formula V=lwh
0.5 x 0.4 x 0.15 = 0.03
That is the volume of the lower prism
2. Do V=lwh again for the volume of the upper prism
0.5 x 0.15 x 0.2 = 0.015
3. After that add both of them up together
0.015 + 0.03 = 0.045

Bekkah's savings account earns 2.75% interest per year.
If she put $12,500 into the savings account, how much interest is earned in a year, in dollars?
Answer:
343.75 dollars
Step-by-step explanation:
First I like to solve for the value of 1% which is 125 then we solve for .10% which is 12.5 then we solve for .01% which is 1.25 I find this helpful because now we have the unit amount for each percent we use in this equation now to multiply we have .05 percent so we take our 1.25 value for .01 percent and multiply by 5 which give us 6.25 then we do .7% we take our .1 percent value and multiply 12.5 x 7 give us 87.5 then we do the 2% we take our 1 percent value and multiply by 2 125 x 2 give us 250 now we add it all together 250+87.5+6.25 = 343.75 I hope this help you out :)

What year(s) did the cities have the same population? What was the population of both cities during the year(s) of equal population? Answers: (year 1995, 425000 people) and (year 2022, 1910000 people)
Baskinville: y = x2 – 22x + 350
Cryersport: y = 55x – 95
I NEED THE EXPLANATION OF HOW TO GET TO THE ANSWER PLEASE
Answer: hope this helps love.
Step-by-step explanation:
years of equal population are 1995 and 2022.
in 1995, population was 425,000 people and in 2022, population was 1,910,000 people.
Step-by-step explanation: Baskinville: y = x2 - 22x + 350
Cryersport: y = 55x - 950
Note that x2 is xsquare not x2
Resolving the quadratic equations carefully will give the values of y and x which represent the population and years.
