Although you didn’t list any equations, here is the correct one:

15 + 5x = 25

1.5 twice a day makes it so it’s 3 miles total. Thus, you need to multiply that by 5 to get the total amount in one week.

x will solve for each evening per day.

Hope this helps!

Answer:

Equation used to find the distance Rin ride in evening is 15 + 5x = 25

Step-by-step explanation:

In a Day Rin ride in morning and in the evening.

In Morning, Rin ride 1.5 miles to school then then ride back to house.

Total Distance ride by the Rin in morning = 1.5 + 1.5 = 3 miles

Let, In evening Rin ride x miles to park and park to home

Total Distance ride by the Rin in evening = x

According to the question,

In 5 days,

3 × 5 + x × 5 = 25

15 + 5x = 25

Therefore, Equation used to find the distance Rin ride in evening is 15 + 5x = 25

A snowstorm began on Monday evening. It snowed steadily until 6:00 am on Tuesday morning when the snow was 12 inches deep. Kevin
poizon [28]

Answer:

what is expected at 7am is 15 inches deep snow but what we have is 12 inches deep snow. The equation has failed in its prediction.

Step-by-step explanation:

In this question, we are asked to calculate if the prediction made by an equation modeled is correct.

Firstly let’s look at the equation in question;

y = 3t - 6

where y is the snow depth and t is the number of hours after midnight.

now we are looking at 7am, that’s 7 hours past 12am, meaning 7 hours after midnight.

let’s plug the value of t as 7 into the equation

y = 3(7) - 6

y = 21-6

y = 15 inches

according to the equation by Kevin, what is expected is 15 inches deep snow but what we have is 12 inches deep snow. The equation has failed in its prediction.

A refrigerator costs $580 a year to run. A family purchases a new one for $1200 that will save them 22% annually in energy costs
NeTakaya

Answer:

It will take nine years and four months for the refrigerator to pay for itself.

Step-by-step explanation:

The new refrigerator which costs $1200, saves the family 22% annually in energy cost.

Since the old refrigerator costs $580 to run, we want to determine how many years it will take for 22% of $580 per year to make $1200.

22% of $580

= 580 × 0.22

= 127.6

That is, it saved then $127.6 per year.

Now,

$1200/127.6

≈ 9.4

Which means, it will take 9 years and 4 months for the refrigerator to pay for itself.

Factorize (4d-3e)2 +6d(4d-3e)​
Natasha_Volkova [10]

Answer:

(4d - 3e)(10d - 3e)

Step-by-step explanation:

(4d - 3e)² + 6d(4d - 3e) ← factor out (4d - 3e) from each term

= (4d - 3e)(4d - 3e + 6d) ← collect like terms inside parenthesis

= (4d - 3e)(10d - 3e)

V2 - 15 = -2v Solve the Quadratic. What are the 2 solutions?
ki77a [65]

Answer:

v=-5 and v=3

Step-by-step explanation:

We are given that

v^2-15=-2v

We have to find  two solutions of quadratic equation.

v^2+2v-15=0

Using addition property of equality

v^2+5v-3v-15=0   (By using factorization method)

v(v+5)-3(v+5)=0

(v+5)(v-3)=0

Substitute each factor equal to 0

v+5=0 and v-3=0

v=-5 and v=3

Hence, two solutions of quadratic equation are

v=-5 and v=3
