Answer:
44
Step-by-step explanation:
The relations can be written using one variable to represent Mikhail's age: m. Gabrielle's age is (m-11), so the sum of their ages is ...
m +(m -11) = 77
2m = 88 . . . . . . add 11
m = 44 . . . . . . . divide by 2
Mikhail's age is 44.
__
Additional comment
Gabrielle is 33.
You could solve this using two variables:
m - g = 11m + g = 77Adding these two equations gives the one we have above:
2m = 88
m = 44
__
You may have noticed we are given the sum and the difference of the two ages. The older Mikhail's age is half the sum of those two numbers. The younger Gabrielle's age is half their difference: (77 -11)/2 = 33. This "half the sum, half the difference" solution is the generic solution to a "sum and difference" problem.
Gabrielle : 33
Mikhail : 44
Explanation:
Let Mikhail's age be x
And Gabrielle's age be y.
======================
Gabrielle is 11 years younger than Mikhail
y = x - 11 [ equation 1 ]
sum of their ages is 77
x + y = 77 [ equation 2 ]
Insert equation 1 into 2
x + x - 11 = 77
2x = 77 + 11
2x = 88
x = 44
Therefore, the age of Mikhail is 44
Find Gabrielle's age:
y = x - 11
y = 44 - 11
y = 33
Therefore, the age of Gabrielle is 33
could someone please help ?
Answer:
No
Step-by-step explanation:
Put x = 2 into both equations:
For x- 10 = 2-10 = 8 (Not > 8)
For -0.5x-4 = -0.5*2-4 = -5 (Not < -8)
Hence, the answer is no.

Answer:
it is 25 as you go down
Step-by-step explanation:
97, 86, 75, 64, etc go in the sequence
I think this is correct
:) Hope you enjoy this :)Answer:
The 25th term is 97
Step-by-step explanation:

Step-by-step explanation:
This shifts the graph down 1 unit, reflects over the x axis, then vertically dilates by a factor of 2.
=============================================================
Explanation:
Refer to the figures below. The screenshots may be a bit on the big side, so brainly might attempt to reduce the size. To fix this, click on the magnifying glass to get a better look. There are 4 images in total.
Figure 1 is the original graph your teacher gave you.
Figure 2 shows the translation of the parabola 1 unit down. This aligns the right piece of the red parabola to the green V curve. This junction location is (1,0).
Afterward, in figure 3, we reflect the parabola over the x axis to have the left endpoint of the parabola (-3,8) move to (-3,-8). Unfortunately the (-3,-8) doesn't match up with the right most piece of the blue cubic curve.
Luckily, a quick fix is to double the y coordinate from -8 to -16 and the two pieces match perfectly. The other junction is (-3,-16). This is shown in figure 4.
To summarize, we did these transformations in the order presented.
Shift down 1 unit (figure 2)Reflect over the x axis (figure 3)Vertically stretch or dilate by a factor of 2 (figure 4)--------------
Now to shift down 1 unit, we subtract 1 from each g(x) output.
Therefore, we go from g(x) to g(x)-1
Reflect over the x axis to get -(g(x) - 1) = -g(x) + 1
Lastly, we double everything when applying the dilation mentioned to end up with the final answer: -2*g(x) + 2
You can use a tool like GeoGebra to check your work. It's the app I used to make the figures shown below.

Variables x, y, and z are integers such that xyz > 0. If xy=30, x/z=2/3, and z=9, what is the value of y?
Explanation:
Plug z = 9 into the second equation and solve for x.
x/z = 2/3
x/9 = 2/3
x = 9*(2/3)
x = 18/3
x = 6
This leads to
xy = 30
y = 30/x
y = 30/6
y = 5
Which is greater: 3x3/2 or 3X2/3 Why?
Answer:
3X3/2 is greater
Step-by-step explanation:
Go left to right and solve the equations.
Equation 1: 3 multiplied by 3 is 9. 9 divided by 2 is 4.5
Equation 2: 3 multiplied by 2 is 6. 6 divided by 3 is 2
Equation 1 yields a greater value.
Answer:
The 3x3/2 is greater than 3x2/3
Step-by-step explanation:
Here is a simple tip when solving these questions:
Decimal form is always great to use because you get the answer instantly instead of finding a common denominator while involving fractions.
Let's solve 3x3/2.
First, do 3x3 which is 9.
Your problem should be 9/2
Now, you could do this as a mixed number but like I said there shall be more work so you should do 9/2 on a calculator or divide but involve decimal point if you have a remainder.
9 divided by 2 is 4.5
9/2 is 4.5 (Above is the interpretation in words)
Next, do 3x2/3
The same thing as last, do 3x2 first.
Your problem should be 6/3
If we know our division facts then 6 divided by 3 is 2.
Lastly, compare our numbers.
The 3x3/2 is 4.5 and the 3x2/3 is 2
Line the numbers up:
4.5
2.0
The tens digit clearly shows that 4 is greater than 2.
Therefore,
The 3x3/2 is greater than 3x2/3

Tom's annual salary is $67,400. a) What is his monthly salary? b)What is his weekly
salary?
Answer:
Monthly salary: $5,617; Weekly salary: $1,296
Step-by-step explanation:
Since there are 12 months in a year, you would divide the number of months by the salary.
67400/12x≈5617
The monthly salary is about $5,617.
Since there are about 52 weeks in a year, you would divide the number of weeks by the salary.
67400/52x≈1296
The weekly salary is about $1,296.
