Which equation can be used to find the value of x?
109=180
x+42=67
x=180-109
42+67-x=180

Answers

Answer:

Step-by-step explanation:

We know every triangle equals 180 so were just going to take 180 - 42 = 138 then were going to do 138 - 67 = 71 we can check our work by doing

42 + 67+ 71 = 180. We also know 67 + 42 = 109.

Lets look at our answers;

A. 109 = 180 + x When solved it gave me; x = -71. We got a positive 71 so this is incorrect.

B. x + 42 = 67 When solved it gave me; x = 25, which is incorrect.

C. x = 180 - 109 When solved it gave me; x = 71

D. 42 + 67 - x = 180 When solved it gave me; x = - 71

Therefore the answer is C.

Answers

(X,Y) = (4,0)

That’s what I got.

Answer:

(4,0)

Step-by-step explanation:

4(-x + 5y) = 4(-)

4x + 3y = 16

-4x + 20y = -16

4x + 3y = 16

23y = 0

23y/23 = 0/23

= 0

y = 0

then for x

we substitute the value gotten from y into the equation.

On her 21st birthday, Sydney deposited $400 in a new bank account that earns 3.7% interest compounded continuously. If there are no other deposits or withdrawals, how much interest will she have earned by her 60th birthday

Answers

Answer:

$1,649.80

Step-by-step explanation:

Sydney will have earned $1293.35 in interest by her 60th birthday.

How to find interest?

To solve this problem, we need to use the formula for continuously compounded interest:

A = P [tex]e^{rt}[/tex]

Where:

A is the final amount of money in the account (including principal and interest)

P is the initial principal (in this case, $400)

r is the interest rate (in this case, 3.7% per year)

t is the number of years the money is invested (in this case, 39 years)

e is the mathematical constant approximately equal to 2.718

Plugging in the values from the problem, we get:

A = $400[tex]e^{0.037 \times 39}[/tex]

Calculating this, we find that A = $400[tex]e^{1.443}[/tex] = $1693.35

Therefore, he will have earned $1693.35 - $400 = $1293.35 in interest by her 60th birthday.

I do not believe that buying a mobile phone to children is a good idea for three reasons. The mobile phone negatively affects children's social life, it distracts them, and they may get abused.First of all, the mobile phone negatively affects children's social lives. They might spend all their time playing on the phone and neglecting to spend time with their family and friends. 2 Moreover, they might even hate going out to the park and prefer to stay home, playing video games on their phones. For all that , mobile phones are not good for children's social life. Secondly, mobile phones might distract children from studying. They spend all their time playing on the mobile phone without studying. Moreover, many children get addicted to mobile phones and then neglect everything else in their life. Mobile phones are very distracting to children. Thirdly, children may get abused. They might get calls and messages from older people who abuse them. Added to that, they can connect to the internet and view websites that are not suitable for their age. We should protect our children both from the internet and from getting abused. To sum up, I think that we should not buy mobile phones for children. They are young and need to be active and play around instead of playing on a mobile phone all the time.
