Answer:

Y=-2.5

Step-by-step explanation:

In order to solve this we need to isolate the variable

First we have to subtract five Y from both sides.

-2y-5=0

Then we have to add five to both sides

-2y=5

then divide by -2 to find the value of y alone

y=-2.5

Eric plans to rent a car for a day from Easy Car Rental. He has a coupon for 25% off the daily base rate of $40. He will also ha

Volgvan

In this situation, there are 2 separate terms (parts of the story). The first part is the information about the coupon that applies to the daily rate of $40. You will represent this as 0.75 (for the 75% that you will be paying) x 40. (The other part of this story is that you are paying $0.15 per mile which is represented as 0.15m. You need to put these together to get 0.75(40) + 0.15m. The 0.25 times 40 can be simplified to say 30, so write it as $30 + $0.15m.

Convert to length 2.1 cm to mm

Anastasy [175]

Here we need to convert 2. 1 cm to mm .

And for that we will use the following conversion .

1cm = 10 mm

So for 2.1 cm, we will multiply 2.1 and 10 to convert it to mm. Therefore 2.1 cm = 2.1* 10mm = 21mm

And that's the required answer .

Mr. Tally inherited $200,000. He used a portion of the inheritance to build a house. He invested the rest of the money for one y

Ivan

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Amount inherited = $200,000

Portion used to build house = h

Invested amount = 200,000 - h

1/3 of (200,000 - h) was invested at 12%

2/3 of 200,000 - h was invested at 15%

Interest from both investment = 8400

Cost of building =?

Using the simple interest formula :

Principal(P) * rate(r) * time

If the investment was for a year:

1st investment :

(200,000 - h)/3 * 0.12 * 1 = (24000 - 0.12h) / 3 = (8000 - 0.04h)

2nd :

(200,000 - h)*2/3* 0.15 * 1 = (20,000 - 0.1h)

Summing both :

8000 - 0.04h + 20,000 - 0.1h = 8400

28000 - 0.14h = 8400

-0.14h = 8400 - 28000

-0.14h = - 19600

= 140,000
