Answer:
Jimena tiene 8 años de edad.
Step-by-step explanation:
Sean [tex]x[/tex], [tex]y[/tex], [tex]z[/tex] las edades de Jimena, su padre y su madre. A continuación, traducimos cada oración relevante del enunciado a expresiones matemáticas:
(i) Si su papá tiene 27 años más que Jimena:
[tex]y = x+27[/tex] (1)
(ii) Su mamá tiene 34 años:
[tex]z = 34[/tex] (2)
(iii) La suma de las tres edades es igual a la diferencia de 10 veces la edad de Jimena, menos 3 años:
[tex]x+y+z = 10\cdot x-3[/tex] (3)
Al aplicar (1) y (2) en (3), tenemos la siguiente ecuación resultante:
[tex]x +(x+27)+34 = 10\cdot x-3[/tex]
[tex]2\cdot x +61=10\cdot x-3[/tex]
[tex]8\cdot x = 64[/tex]
[tex]x = 8[/tex]
Jimena tiene 8 años de edad.

Solve For x.
x
_ = 4
40
A) 16
B) 36
C) 160
D)176
Answer:
It would be 160 (C)
Step-by-step explanation:
160 is the only one that works if u rplace x with 160.
Answer:
160
This is how I got my answer I divided each answer by 4 to see if it equaled 40 and 160 divided by 4 equals 40 so 160 is your answer
Calculate the frequency of light that has a wavelength of
4.25 x 10^-9m and a velocity of 300 m/s.
Answer:
The velocity of light, v, is the product of its wavelength, λ , and its frequency, f. This means that the wavelength is the velocity, v, divided by the frequency, f.
Wavelength of light = velocity of light / frequency of light
λ = v/f
λ = Wavelength of light, meters
v = Velocity of light (c = 3.0 x 108 m, for speed of light if not otherwise defined)
f = frequency of light, Hz

Can someone help.me with this pls.....
Answer:
5/14
Step-by-step explanation:
To work this out, we simply need to divide 1 3/4 miles by 4 9/10 miles.
1 3/4 ÷ 4 9/10
Start by converting both terms to improper fractions:
(4/4 + 3/4) ÷ (40/10 + 9/10)
= 7/4 ÷ 49/10
To divide, we simply multiply by the reciprocal of the second fraction:
7/4 * 10/49
= 70 / 196
Now we can take out common factors of the 70 / 196
70 / 196
= (5 * 2 * 7) / (14 * 2 * 7)
= 5 / 14
So the straight section of the track is five fourteenths of the entire length.
The difference between the roots of the quadratic equation x2 -14x +q =0 is 6. Find q
9514 1404 393
Answer:
q = 40
Step-by-step explanation:
When the quadratic has roots p and r, it can be factored as ...
(x -p)(x -r) = x² -(p+r)x +pr
So, the sum of the roots is 14, and their difference is 6. This lets us find the roots from ...
p + r = 14
p - r = 6
2p = 20 . . . add the two equations
p = 10
r = 14 -p = 4
The value of interest is then ...
q = pr = (10)(4)
q = 40
__
The graph shows the roots to be 4 and 10, as we found.

Answer:
slope= 6.25
Step-by-step explanation:
the slope represents the meters he travels per second
Answer:
The slope is 0.16
Step-by-step explanation:
You have the run over the rise as a slope equation.
x/y or 5/31.25
The answer to that will be the answer to all of them.
5/31.25=0.16
10/62.5=0.16
15/93.75= 0.16
The rate of change(or slope) is 0.16.
The slope represents time over distance(t/d or x/y) for Oren's 100-meter race.

A bookstore costs $96 a day to keep open, and it spends $12 for each book that it sells. If each book sells for $18, what is the break-even point
for this bookstore?
Answer: The break even point is when they have sold 16 books and have made $288
Step-by-step explanation: The costs are modeled in the equation y = 12x + 96. x is the number of books sold.
The earnings are modeled by he equation y = 18x.
Substitute 18x for y and solve for x.
18x = 12x + 96 Subtract 12x from both sides.
6x = 96 Divide both sides by 6
x = 16
Substitute into the original equations to solve for y
y = 12(16) + 96
y = 192 + 96
Y = 288
y = 18(16)
y = 288

C = 12n + 90

Answer:
The system is consistent; it has one solution ⇒ D
Step-by-step explanation:
A consistent system of equations has at least one solution
The consistent independent system has exactly 1 solutionThe consistent dependent system has infinitely many solutionsAn inconsistent system has no solution
In the system of equations ax + by = c and dx + ey = f, if
a = d, b = e, and c = f, then the system is consistent dependent and has infinitely many solutionsa = d, b = e, and c ≠ f, then the system is inconsistent and has no solutiona ≠ d, and/or b ≠ e, and/or c ≠ f, then the system is consistent independent and has exactly one solutionIn the given system of equations
∵ -2y + 2x = 3 ⇒ (1)
∵ -5y + 5x = 12 ⇒ (2)
→ By comparing equations (1) and (2)
∵ -2 ≠ -5
∵ 2 ≠ 5
∵ 3 ≠ 12
→ By using the 3rd rule above
∴ The system is consistent independent and has exactly one solution
∴ The system is consistent; it has one solution

A TV originally priced at $500 is discounted 5%. How much is the discount?
Answer:
The discount price for the TV is $475
Step-by-step explanation:
You multiply the original price by 0.95 (95%)
Answer:
$400
Step-by-step explanation:
Take the original price. Divide the original price by 5. Alternatively, divide the original price by 100 and multiply it by 20. Subtract this new number from the original one.
500/100=5
5*20=100
500-100=400

April. The actual rainfall
was 5.8 inches. What
was the percent error of
the estimate to the
nearest tenth of a
percent?
