Answer:

  • interest: $144
  • principal plus interest: $944

Step-by-step explanation:

The amount of interest is found using the simple interest formula. That is added to the principal to find the total account balance.

__

<h3>Interest</h3>

  I = Prt . . . . . P = principal, r = annual rate, t = number of years

  I = $800·0.06·3 = $144

The simple interest earned in 3 years is $144.

__

<h3>Principal plus interest</h3>

Adding that to the principal gives ...

  $800 +144 = $944

The total principal plus interest is $944.

Perform the indicated operation. 10 3/7 + 19 5/9
DanielleElmas [232]
Given expression is

10 \frac{3}{7} + 19 \frac{5}{9}

Now convert mixed fraction as improper fraction as

10 \frac{3}{7} + 19 \frac{5}{9} =  \frac{10*7 + 3}{7} +  \frac{19*9+5}{9}
                                                         =  \frac{73}{7}  +  \frac{176}{9}
                                                          =  \frac{73*9 + 176 * 7}{63}
                                                         =  \frac{657 + 1232}{63} =  \frac{1889}{63}
Now we can convert \frac{1889}{63 } = 29 \frac{62}{63}

So the answer is 29 \frac{62}63}

multiply 1 and 12= 12

find two numbers that multiply to get twelve AND add together to get -7(the middle number)

the two numbers are -3 and -4 (they add up to get -7 AND multiply together to get 12)

plug in these numbers for -7x

x^{2} -3x-4x+12

x(x-3)-4(x-3)

Is (2, -4) a solution to the inequality 2x - 3y &lt; 15? Yes or No
miss Akunina [59]

Answer:

No.

Step-by-step explanation:

We substitute the values x = 2 and y = -4 into the inequality.

Left side = 2(2) - 3(-4) = 4 + 12

= 16

Now the right side is 15 so we get 16 < 15 which is incorrect.

So (2, -4) is not a solution.
