Sidana [21]3 years ago

Answer:

x = 1/2

Step-by-step explanation:

5(2x + 1) + 4 = 6 (3x + 2) - 7

~Simplify both sides

10x + 9 = 18x + 5

~Subtract 9 from both sides

10x = 18x - 4

~Subtract 18x to both sides

-8x = -4

~Divide -8 to both sides

x = 1/2

Best of Luck!

5(2x+1)+4=6(3x+2)-7

10x+5+4=18x+12-7

10x-18x=12-7-5-4

-8x=-4 (-1)

8x=4

x=4/8 (/4)

x=1/2

Radda [10]

Answer:

Total fine paid by Amelia =  £1.44

Step-by-step explanation:

Given that:

Number of days = 27 November to 12 December

Number of days = 16 days

Per day fine = 9p

Total fine = Per day fine * Number of days

Total fine = 9 * 16

Total fine = 144p

1£ = 100p

144p = \frac{144}{100}

144p = £1.44

Hence,

Total fine paid by Amelia =  £1.44

What is measurement angle C?<br>​
11Alexandr11 [23.1K]
So you know all angles in a triangle add to 180 degrees and you have x + 3x + 2x which adds to 6x so you do 180/6 to get x = 30 and c = 2x so you do 30 x 2 which is 60 degrees. Hope this helps :)

A family is purchasing a house and needs to finance a $195,000 mortgage from the bank with an annual percentage rate (APR) of 5.
Alecsey [184]

Monthly payment is $1082.84.

Solution:

Given data:

Principal = $195000

Rate per year = 5.3\% =\frac{5.3}{100}=0.053

Rate per month = \frac{0.053}{12} =0.004416

Time = 30 × 12 = 360 month

<u>To find the monthly payment using formula:</u>

$\text{Monthly payment}=P\times\frac{r(1+r)^n}{(1+r)^n-1}

                           $=195000\times\frac{0.004416(1+0.004416)^{360}}{(1+0.004416)^{360}-1}

                           $=195000\times\frac{0.004416(1.004416)^{360}}{(1.004416)^{360}-1}

If you simplify this using calculator, we get

                           =1082.84

Monthly payment = $1082.84

Option C is the correct answer.

Hence monthly payment is $1082.84.

Answer:

In Step 2, 90 should be multiplied by the quantity 10 – 12, not by 10

Step-by-step explanation:

90 * x - 90 * 12 = 90(x - 12)

From the question, x = 10

Hence,

90(10 - 12)

(90* 10) - (90 * 12) - - - > correct evaluation

900 - 1080

= - 180

Hence, both values in the bracket, that is 10 and - 12 should be multiplied by 90. Not just 10 alone.
