Roman solved the equation 5 a + 2 b = 10 for a. His steps are shown below. 1. Subtract 2b: 5 a + 2 b minus 2 b = 10 minus 2 b. 5 a = 10 minus 2 b. 2. Multiply by 5: a = 50 minus 10 b. Which statement about Roman’s work is true? In step 1, he needed to add 2b to both sides of the equation. In step 1, he needed to divide both sides of the equation by 2b. In step 2, he needed to divide both sides of the equation by 5. In step 2, he needed to subtract 5 from both sides of the equation.

Write 25 % as a fraction

Answers

Answer:

1 / 4

hope this helps (✿◡‿◡)

Change 25% to a decimal as step one.

So, 25% becomes 0.25.

0.25 means 25/100.

We can reduce 25/100 to the lowest terms.

Doing so, we get 1/4. Do you know how 25/100 becomes 1/4?

Look here:

We divide the numerator and denominator by the greatest common factor.

25÷ 25 = 1

100 ÷ 25 = 4

Thus, we get 1/4 as the final answer.

Is this in any way clear?

POINT: (12,5)

SLOPE : -3


Write is the equation to the line that is parallel to the y=6x+19, but goes through the point (4,-5)


Answers

Answer:

the first answer ( I think these are 3 different questions) is y = -4x + 7

the second answer is y = -3x + 5

the third answer is y = 6x - 5, because the lines are parallel, they have the same slope and the y int is -5 from the point given.

URGENT!!!!!! URGENT!!!! WILL MARK AS BRAINLIEST!!!! Benjamin considers purchasing a car for $35,000. He has been approved for a 6-year loan for $30,000 with an interest rate of 5.25%. He also has the option to lease the car for $600 per month for 6 years with a $2,500 down payment. Using the loan amortization formula, how much money does Benjamin save over the 6 years if he purchases the car? Do not consider the future value of the car in your answer. Enter your answer as a dollar amount, such as: $4253

Answers

Answer: $1250

Step-by-step explanation:

Given data:

Cost of car = $35,000

Down payment made = $2500

Interest rate = 5.25%

Duration of loan = 6 years

Loan Amount = $3000

Solution:

I = prt/100

where

I = interest

p = principal ($30,000)

r = 5.25%

t = 6

I = $30,000 * 5.25 * 6 /100

= $9450

interest payable on the loan in 6 years is $9450.

Rental

=$600 monthly * 6(12)

= $43,200

Amount made from renting the car is $43,200.

• Money saved by Benjamin in 6 years

= $43,200 – $32500 + $9450

= $43,200 – $41,950

= $1250

Benjamin would have saved $1250 in 6 years.

The distance between (-4,6) and (3, -7) is *round to the nearest tenth!!

Answers

Use the Pythagorean theorem
d = sqr ((x2-x1)^2 + (y2-y1)^2)
d = sqr ((3+4)^2 + (-7-6)^2)
d = sqr ((7)^2 + (-13)^2
d = sqr ((49 + 169)
sqr of 218 = 14.76

The required distance between points (-4,6) and (3, -7) is 14.8.

Given that,

To determine the distance between (-4,6) and (3, -7).


What is coordinate?

Coordinate, is represented as the values on the x-axis and y-axis of the graph

Here,

distance between (-4,6) and (3, -7) is given by the distance formula,
Distance = √[( x₁ - x₂ )² + ( y₁ - y₂ )²]
Distance = √[( -4 - 3 )² + ( 6 - (-7) )²]
Distance = √[( -7 )² + (13 )²]
Distance = √[49 + 169]
Distance = √218
Distance = 14.8

Thus, the required distance between points (-4,6) and (3, -7) is 14.8.
