Answer:

For number remember that the negative number are smaller, but if it question like this which one is bigger -5 or -6 will -5 will be the answer because it is not smaller than -6. For ratios just remember divide or number of something like there are 3 to 8 child in the classroom then thee ratios would be 3:8. Lastly for the times tables learn all of your times tables like your favorite game, so things will be easier on you.

If you borrow $12,000 for 30 months at 6.5% simple interest, what is the total amount you will have to repay?
Eddi Din [679]
From your statement, i can assume that the interest 6.5% is for yearly.

30 months = 2.5 years

1 year interest for 100           = 6.5
1 year interest for 12000       = 6.5/100 * 12000
                                              = 780

2.5 years interest for 12000  = 780*2.5
                                              = 1950

so the total amount that you have to pay 
12000 + 1950
$ 13950

I need help w/ this problem...please don't answer if you don't know and PLEASE answer as fast as you can...I'm desperate.
Wittaler [7]
There's a very simple rule for geometries like this. The measure of the arc is double the measure of the angle. It helps to remember this.

Your angle is 65°.
The measure of the arc is 2×65° = 130°.

Solve, showing all work: (4x − 6) + (3x + 6)<br><br> Note: Drop the parenthesis and add like terms.
qwelly [4]

Answer:

The answer is 7x

Step-by-step explanation:

To solve the problem drop the brackets and add the like terms

∵ (4x - 6) + (3x + 6)

- There is no number multiplied by each bracket so drop the

    brackets without any change in the values inside them

∴ (4x - 6) + (3x + 6) = 4x - 6 + 3x + 6

- The terms 4x and 3x are like terms, so add them

∵ 4x + 3x = 7x

- The terms -6 and 6 are like terms, so add them

∵ -6 + 6 = 0

∴ 4x - 6 + 3x + 6 = (4x + 3x) + (-6 + 6)

∵ (4x + 3x) + (-6 + 6) = 7x + 0

∴ 4x - 6 + 3x + 6 = 7x

∴ (4x - 6) + (3x + 6) = 7x

The answer is 7x
