How many solutions are there to the equations 5x+1=3x+7?

Answers

Answer 1

Answer: 5x + 1 = 3x + 7

Subtract 3x to both sides:

2x + 1 = 7

Subtract 1 to both sides:

2x = 6

Divide 2 to both sides:

x = 3

So this equation only has 1 solution.

Answer 2

Answer: $5x+1=3x+7\n2x=6\nx=3$

One.

Electrons and protons are particles in an atom with equal but opposite charges. Electrons have a negative charge and protons have a positive charge. What is the charge amount of an atom with 2 more electrons than protons?

Answers

Answer:

$-3.2\cdot 10^(-19)C$

Step-by-step explanation:

- Protons are positively charged particles contained in the nucleus of the atom. They have a charge of $q_p=+1.6\cdot 10^(-19)C$

- Electrons are negatively charged particles orbiting around the nucleus of the atom. They have a charge of $q_e = -1.6\cdot 10^(-19)C$

For a neutral atom, the number of protons is equal to the number of electrons, so the total charge of a neutral atom is:

$Q=Nq_p + Nq_e = N(q_p+q_e)=N(+1.6\cdot 10^(-19)-1.6\cdot 10^(-19))=0$

In this problem, we have an atom having an excess of 2 electrons, i.e. it has 2 more electrons than protons.

Therefore, the charge of this atom will be:

$Q=0+2q_e$

and substittuing, we find

$Q=2(-1.6\cdot 10^(-19))=-3.2\cdot 10^(-19)C$

Amanda figured out that her aunt's age is 5 more than one - half the square of her own age. If Amanda is 8 years old, how old is her aunt? A) 21 B) 32 C) 37 D) 59
THE ANSWER IS 37 BUT HOW DO U SOLVE IT

Answers

so the way that i would solve it is i would take 8 and square it which would equal 64 then devide it by 2 and that gives me 32 and then add 5 which gives me 37 and thats how i would get the answer. (8^{2}=64 /2=32+5=37)

the answer is D because that's 5 more than one (half the square of her own age) ;)

If Jill bought an item on the sale rack and saved a total of $84, what is the value of x in the table above? (x=1/4)

84 = 3/4
how much is 1/4?
possible answers:
$21
$28
$84 - not
$112 - not

Answers

The best way to solve this is to put it into a proportion:
$(x)/(84) = ( (1)/(4) )/( (3)/(4) )$
So you cross multiply to get:
$21= (3)/(4) x$ (the 21 is from $(1)/(4)$ •84)
Then multiply by $(4)/(3)$
And you get $28, so the reduced price would be $28.
