16 because the neg next to the subtraction sign becomes positive then you’re just adding 14+2.

The sum of twice a number and three is greater than forty-nine

We divide both sides by 2 to isolate x... 
x > 23 
There you go. Any number greater than 23 is a correct answer to your problem. Let's verify by substituting x for 24. 
2(24) + 3 > 49 
48 + 3 > 49 
51 > 49 </span>

Correction is the question: 6\frac{1}{2}%% = 6.5%

Answer:

Amount to be repaid is $335798.833

Step-by-step explanation:

Amount of loan = $332,200

Rate of interest = 6.5%

time =  2months = 2/12 = 1/6 years

The amount of interest is simple interest

SI = \frac{P * R * T}{100}

    =\frac{ 332200 * 6.5 *1 }{100 * 6}

    = $3598.833

Final amount to be repaid = 332200+ 3598.833

                                            = $335798.833

The length of a rectangle is 7 cm than 6 times its width. It's area is 10 square centimeters. Find the dimensions
ad-work [718]
So legnth is 7 more than 6 times width
l=7+6w
area=10 cm^2

lw=area

subsitute
7+6w for l
(7+6w)(w)=10
7w+6w^2=10
subtract 10 from both sides
6w^2+7w-10=0
factor
multiply 6 and -10
get -60
now find what 2 numbers multiply to get -60 and add to get 7
the answe ris -5 and 12
split up 7w into that
6w^2+7w-10=0
6w^2+12w-5w-10=0
group
(6w^2+12w)+(-5w-10)=0
undistribute factors
(6w)(w+2)+(-5)(w+2)=0
reverse distribute (ab+ac=a(b+c)
(w+2)((6w)+(-5))=0
(w+2)(6w-5)=0
set each to zero
w+2=0
subtract 2
w=-2
false, legnths cannot be negative

6w-5=0
add 5
6w=5
divide both sides by 6
w=5/6
subsitute
l=7+6w
l=7+6(5/6)
l=7+5
l=12


legnth=12 cm
width=5/6 cm
