Solve for m:
2 (m + 7) = -4- m
Your answer
Answer:
m = -6
Step-by-step explanation:
2 (m + 7) = -4 - m
2m + 14 = -4 - m
3m + 14 = -4
3m = -18
m = -6
Hopefully this helps!
Brainliest please?
Answer:
m = -6
Step-by-step explanation:
To solve this equation for m, we multiply out the left side to remove the parentheses:
2m + 14 = -4 - m
Next, we combine like terms: 2m and -m are like terms, as are 14 and -4:
3m = -18
Dividing both sides by 3 yields m = -6

resolver el sistema x-y =6 y este otro 2x+5y= -2 porfaaaa es para mañana
Answer:
x =4
y = -2
Step-by-step explanation:
a) x - y = 6
b) 2x + 5y = - 2
a) x = y + 6
b) 2(y+6) + 5y = -2
2y + 12 + 5y = -2
7y = -2 -12
y = -14/7
y = -2
a) x - (-2) = 6
x +2 = 6
x = 6-2
x = 4

Volume Of This Cylinder
Answer:
2827.4 cm
Step-by-step explanation:
Volume of cylinder
V= π*r^2*h
H= height and r= radius
H= 9cm and r = diameter ÷ 2
r= 20cm ÷2 = 10cm
V= 22/7* 10^2* 9cm
V= 2829cm^3
The volume of this sphere is 972 pi cubic inches. What is its radius?
A sphere.
Recall the formula Sphere Volume = four-thirds pi r cubed.
7 inches
9 inches
108 inches
324 inches
volume of a sphere = ⁴/₃ πr³
⇒ 972π in³ = ⁴/₃ πr³
729 in³ = r³
r = 9 in
∴ the radius of a sphere of volume 972π in³ is 9 inches.Answer:

Answer:
Sorry I can't give you a straight answer right now because I'm in a hurry but here is some help;
Step-by-step explanation:
Remember:
When adding positive numbers, count to the right. When adding negative numbers, count to the left. Add when two of the same signs appear next to each otherFind the exponential function that satisfies the given conditions:
Initial value = 66, decreasing at a rate of 0.5% per week (5 points)
f(t) = 0.5 ⋅ 0.34t
f(t) = 66 ⋅ 1.5t
f(t) = 66 ⋅ 0.995t
f(t) = 66 ⋅ 1.005t
Answer:
C. f(t) = 66 * 0.995^tStep-by-step explanation:
Required function is:
f(t) = 66*(1 - 5/100)^t = 66*0.005^tThe matching option is C
Mr. Chan places $4000 in a bank as a fixed deposit for 2 years. The bank offers an interest compounded yearly. At the end of 2 years, he receives a total of $4243.60. Find the interest rate.
Answer:
Step-by-step explanation:
Mr. Chan originally placed 4,000 in the bank as a fixed deposit for 2 years.
Each years the bank added a certain amount of interest.
At the end of the 2 years he gained 243 dollars and 60 cents just from interest.
How to solve:
Simply take away the 4 in the amount of money
Leaving: $243.60
( 2 years )
Now divide 243.60 by 1/2
which is 121.8
Mr.Chan got 121.8 worth of interest a year
$10.5 a month
$2.3 a week
6 cents a day
All in 2 years.

7. When Mrs. Santo lived in China, temperature was measured in Celsius. She constantly had to convertir
Celsius to Fahrenheit until she started learning Celsius temperatures and how warm they are.
The formula to convert from Celsius to Fahrenheit is F = = C) + 32
The mean temperature for one month was 34°C and the standard deviation was 2.27.C. Applying what
know about multiplying by a constant and adding a constant, what was the mean and standard deviation
Fahrenheit? Be sure to show your work for both the mean and the standard deviation.
Answer:
Mean: [tex]93.2\; \rm ^{\circ} F[/tex].
Standard deviation: [tex]4.086\; \rm ^{\circ} F[/tex].
Step-by-step explanation:
Consider a random variable [tex]X[/tex] with mean [tex]\overline{X}[/tex] and variance [tex]{\rm Var}(X)[/tex].
If a random variable [tex]Y[/tex] is obtained by linearly transforming [tex]X[/tex] for some constants [tex]m \ne 0[/tex] and [tex]b[/tex], then the mean of [tex]Y\![/tex] would be:
[tex]\overline{Y} = m\, \overline{X} + b[/tex].
[tex]\mathrm{Var}(Y) = m^{2} \, \mathrm{Var}(X)[/tex].
The standard deviation of a random variable is the square root of its variance. Therefore, the standard deviation of [tex]Y[/tex] would be:
[tex]\begin{aligned}\mathrm{SD}(Y) &= \sqrt{\mathrm{Var}(Y)} \\ &= \sqrt{m^{2}\, \mathrm{Var}(X)} \\ &= m\, \sqrt{\mathrm{Var}(X)} \\ &= m\, \mathrm{SD}(X)\end{aligned}[/tex].
In this question, the random variable [tex]F[/tex] is obtained by linearly transforming [tex]C[/tex] using the constants [tex]m = (9/5)[/tex] and [tex]b = 32[/tex]. That is:
[tex]F = (9/5)\, C + 32[/tex].
It is given that mean [tex]\overline{C} = 34[/tex] while standard deviation [tex]\mathrm{SD}(X) = 2.27[/tex]. The mean and standard deviation of [tex]F[/tex] obtained from the linear transformation would be:
[tex]\begin{aligned}\overline{F} &= m\, \overline{C} + b \\ &= (9/5) \times 34 + 32\\ &= 93.2\end{aligned}[/tex].
[tex]\begin{aligned}\mathrm{SD}(F) &= m\, \mathrm{SD}(C) \\ &= (9/5) \times 2.27 = 4.086\end{aligned}[/tex].
Thus, when measured in degrees Fahrenheit, the corresponding mean would be [tex]93.2\; \rm ^{\circ} F[/tex] and and standard deviation would be [tex]4.086\; \rm ^{\circ} F[/tex].
