help idk how to do math

use the distributive property

Answers

Answer:

Distributive property is when you multiply or add the numbers in the parentheses equally to the number outside the parentheses.

That probably isn't a good answer, here's what I found on google:

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Step-by-step explanation:

I'll do #10 as an example:

(x-5)y

distribute the numbers-  y(x)-y(5)

without the parentheses-  yx-y5

you can't really get an answer by multiplying a number and a variable, or a variable and a variable, so you just leave them and take the parentheses.

Here's #11:

-4(2a-3b+c)

distribute the numbers-  (-4*2a)-(-4*3b)+(-4c)

solve-  -4*2= -8

-4*3= -12

-8a-(-12)b+4c

*I dunno how to use parentheses for negative numbers but what I did for distributing is pretty much the same thing

Hope this helps you.

whats -5 5/8 divided by -4 7/12 as a fraction?

Answers

Turn the mixed numbers into improper fractions:
-5 5/8 = - 45/8
-4 7/12 = - 55/12

Remember, when you divide by a fraction, you take its reciprocal and multiply it:
(-48/8) / (-55/12) = (-48/8) x (-12/55)

Simplify the fraction:
72/55

I think this is the answer.

what do racecar drivers like to do

Answers

They like to flip over and set their car on fire

In general, racecar drivers like to engage in activities related to speed, adrenaline, and competition both on and off the race track.

Racecar drivers have a passion for speed and competition, which extends beyond their time on the track. When not racing, many of them enjoy activities that provide an adrenaline rush, such as go-karting, motocross, or other extreme sports. Staying physically fit is crucial for their performance, so they often participate in rigorous training, including cardio workouts, strength training, and reflex drills.

Additionally, they may spend time honing their racing skills through simulators or practice sessions on race circuits. Away from the track, some drivers may have interests in classic cars, car collecting, or automobile engineering. Their lifestyle revolves around the excitement of racing and everything associated with it, both professionally and recreationally.

what two numbers multiply to -36 and add up to 5

Answers

Answer:

9 and -4

Step-by-step explanation:

Finding these 2 numbers can be found by guessing and checking. By doing this, it will get you the numbers 9 and -4.

First, test if they multiply to -36:

9(-4)

= -36

Then, check if they add up to 5:

9 + (-4)

= 5

So, 9 and -4 are the 2 numbers that multiply to -36 and add to 5

Neil's bank offered him a 4.95% interest rate for his mortgage. If he
purchases 3 points, what will his new rate be?
O A. 0.375%
O B. 4.575%
C. 1.75%
O D. 4.375%

Answers

I honestly think it’s C

Neil's new interest rate after purchasing 3 points would be 7. 95%. The closest option is B. 4.575%.

How to calculate the interest rate?

To calculate the new interest rate after purchasing points, we need to know the cost of one point and the number of points purchased.

One point typically costs 1% of the mortgage amount, so three points would cost 3% of the mortgage amount. The cost of the points is usually paid upfront at closing.

Assuming Neil's mortgage amount is $100,000, the cost of 3 points would be:

3% x $100,000 = $3,000

To calculate the new interest rate, we need to add the cost of the points to the original interest rate and then recalculate it as a percentage:

New rate = Original rate + (Cost of points / Mortgage amount)

New rate = 4.95% + ($3,000 / $100,000)

New rate = 4.95% + 3%

New rate = 7.95%

So, Neil's new interest rate after purchasing 3 points would be 7. 95%. The closest option is B. 4.575%.
