Step-by-step explanation:
(5+w) + w + (w-2)=120
-5 from both sides
w+w+(w-2)=115
+2 from both sides
w+w+w=117
117/3 = w

Answer:
x = 9
Step-by-step explanation:
5+ 2/3x= -x+20.
Add x to each side
5+ 2/3x +x= -x+x+20
5 + 2/3x+3/3x = 20
5 + 5/3x = 20
Subtract 5 from each side
5+5/3x -5 = 20-5
5/3x = 15
Multiply each side by 3/5
3/5 * 5/3x = 15*3/5
x = 9
Answer:
Step-by-step explanation: 5+2/3x= -x+20
-5. -5
2/3x= -x +15
+x +x
1 2/3x/1 2/3 = 15/1 2/3

HELP ME ASAP Given f(x) = 5x + 2 and g(x) = -x -3, find h(x) = f(x) + g(x).
Answers
Answer:
h(x) = 4x - 1
Step-by-step explanation:
h(x) = f(x) + g(x)
= 5x + 2 - x - 3 ← collect like terms
= 4x - 1
Answer:
4x-1
Step-by-step explanation:
h(x)=5x+2+ (-x-3)
h(x) = 5x+2-x-3
h(x)=5x-x+2-3
h(x)=4x-1
There are two twins. One twin wants to explore the planet near Proxima Centauri and leaves on a spaceship traveling at 90% of the speed of light, while the other twin stays home on Earth. How much does the twin on Earth age while the other twin travels to Proxima Centauri?
Answers
Answer:
4.7 years
Step-by-step explanation:
Distance of planet from Earth = 1.3 parsec
We know that 1 parsec = 3.26 light years
And a light year is the distance traveled by light in time period of 1 year.
So, Distance of planet from Earth = 1.3 [tex]\times[/tex] 3.26 = 4.24 light years
Given that, the person travels at a speed equal to 90% of the light speed.
To travel to the planet from Earth, Light takes 4.24 years.
To travel the distance [tex]D[/tex], at a speed [tex]s[/tex] light takes time of 4.24 years.
To travel the distance [tex]D[/tex], at a speed [tex]0.90s[/tex], the person takes time:
[tex]\dfrac{4.24}{0.90} = \bold{4.7\ years}[/tex]
So, the twin on Earth ages by 4.7 years.
Answer:
4.7 years

2ax - 15 = 3(x + 5) + 5(x - 1) In the equation above, a is a constant. If no value of x satisfies the equation, what is the value of a ?
NEED EXPLANATION!
Answers
Answer:
Step-by-step explanation:
Hello,
let s regroup the terms
2ax - 15 = 3(x + 5) + 5(x - 1) *** add 15 to both sides ***
<=> 2ax = 15 + 3x + 15 + 5x - 5 *** develop to remove the parentheses***
<=> 2ax = 8x + 25 *** simplify ***
<=> (2a-8)x = 25 *** subtract 8x from both sides ***
<=> (a-4)x=25/2 *** divide by 2 both sides ***
There is no solution is a-4 = 0 ,
because it would mean 0 = 25/2 and this is not possible
So it gives a = 4
Thanks
In the case when no value of x satisfies the equation so there the value of a should be 4.
Calculation of the value of a:Since
the equation is
2ax - 15 = 3(x + 5) + 5(x - 1)
2ax = 15 + 3x + 15 + 5x - 5
2ax = 8x + 25
(2a-8)x = 25
So a = 4
hence, In the case when no value of x satisfies the equation so there the value of a should be 4.

Gregoria borrowed $2,450, to be paid back at 3.5% simple interest. She repays $3221.75. How many years was the loan period?
Answers
Answer:
90.7yrs.
Step-by-step explanation:
Given parameters:
Amount borrowed = $2450
Interest rate = 3.5%
Amount repaid = $3221.75
Unknown:
Number of years the load was paid = ?
Solution:
The formula of simple interest;
I = PRT
Where I is the interest
P is the principal
R is the rate
T is the time
To find the interest;
Interest = Amount paid back - loan = 3221.75 - 2450 = 771.75
Now;
P = IRT
2450 = 771.75 x [tex]\frac{3.5}{100}[/tex] x T
2450 = [tex]\frac{2701.25T}{100}[/tex]
T = [tex]\frac{245000}{2701.125}[/tex] = 90.7yrs
The number of years of the loan period was 90.7yrs.
