Answer:
1994
Step-by-step explanation:
x+(x+1)+(x+2)=75
3x=72
x=24
2018-24=1994
Por lo tanto, el hermano menor tiene 24 años y nació en 1996
Usando un sistema de ecuaciones, se encuentra que el menor nacio en 1994.
Tres hermanos nacieron en anõs consecutivos, o que implica que sus edades son dadas por: [tex]x, x + 1, x + 2[/tex].Suma de 75, o sea:
[tex]x + x + 1 + x + 2 = 75[/tex]
[tex]3x + 3 = 75[/tex]
[tex]3x = 72[/tex]
[tex]x = \frac{72}{3}[/tex]
[tex]x = 24[/tex]
O sea, el menor tiene 24 años en 2018.
2018 - 24 = 1994, o que implica que el menor nascio en 1994.

Solve the two-step inequality and match the answer to the graph
Answer:
(see below; answers at the bottom)
Step-by-step explanation:
-4x + 7 ≥ 27
-4x ≥ 20
-x ≥ 5
Whenever you multiply or divide by a negative number in an inequality, flip the sign:
x ≤ -5
x/1 - 9 < -10
x - 9 < -10
x < -1
3x - 10 < -25
3x < -15
x < -5
5 (x - 2) > -15
Use Distributive Property:
5x - 10 > -15
5x > -5
x > -1
A) x < -5
So, A) 3x - 10 < -25.
B) x ≤ -5
So, B) -4x + 7 ≥ 27.
C) x < -1
So, C) x/1 - 9 < -10.
D) x > -1
So, D) 5 (x - 2) > -15.

7 (4.3 + p) = 7 (4.3 + 5.7)
= 7 (10)
= 70
Answer:
4.3 + 5.7 = 10

Duane And his family are playing a game Dwayne scores 11 points each tile matches 1/3 point model the solution with an equation how many tile matches this Dwayne make
Answer:
33 tiles
Step-by-step explanation:
Given
[tex]1\ tile = \frac{1}{3}\ points[/tex]
Required
Determine the number of tiles in 11 points
Represent this with x. So, we have:
[tex]1\ tile = \frac{1}{3}\ points[/tex]
[tex]x = 11\ points[/tex]
Cross Multiply
[tex]x * \frac{1}{3} = 11 * 1[/tex]
Multiply through by 3
[tex]3*x * \frac{1}{3} = 11 * 1*3[/tex]
[tex]x = 33[/tex]

help me guysssssssssssssssss :D
Answer:
Slope=3
Step-by-step explanation:
m=y2-y1/x2-x1
m=19-10/6-3
m=3
Answer: The answer is C which is "m = 3"
Step-by-step explanation: To find the slope, the formula is change of y / change of x. The change of y in the graph is 9, and the change of x is 3. 9 divided by 3 is 3. Therefore, the option "m=3" is the correct answer.

plz help me hurry
Answer:
x=-1
Step-by-step explanation:
-2x - 5 = -3
add 5 to both sides
-2x = 2
divide both sides by -2
x = -1
Answer:
x = -1
Step-by-step explanation:
-2x - 5 = -3
Same to both sides:
-2x = -3 + 5
Simplify:
-2x = 2
Divide by -2 on each side to isolate x:
x = -1

A movie theater is located at (1,7) after walking 6 blocks to the movie theater you meet you friend at your friend's house. What ordered pair corresponds to the location of your friend's house
Answer:
(-5,1)
Step-by-step explanation:
Given the coordinate of the location of the theatre as (1,7)
If this was the coordinate after moving 6 blocks to your friend's house, then the coordinate of the location of my friend house will be gotten as thus;
C = (1-6, 7-6) (since he moved 6blocks)
C = (-5, 1)
Hence the required coordinate is (-5,1)

Ayako claims that there are centers of dilations through which a dilation of line n by a factor leaves n changed. Determine whether each point below represents a center of dilation that supports ayako's claim
Answer:
The answer is below
Step-by-step explanation:
The question is not complete. The points are not given, but I can explain it.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.
Dilation is the enlargement or reduction in the size of an object by a factor k. If a line AB is dilated by a factor k, with a center of dilation on the line AB, if the new line formed is A'B', then A'B' would lie on the same line AB irrespective of the dilating factor.
Dilation of a line segment is to smaller or larger a line with a specific scale factor. The line n when dilated with the center of dilation on the line, it will bring no change on the original line.
Given information
The line which is dilated is n.
DilationDilation of a line segment is to smaller or larger a line with a specific scale factor. If this scale factor is more than 1 then the line segment will larger otherwise smaller.
In the given problem a line n is dilated with the a scale factor that leaves the changed of n.
If the entire line is dilated and the point of this line passes through center of dilation then the change will be nothing. If dilated from the center of dilation the scale factor does not matter.
To find center of dilation which supports Ayako's claim the point below which represents the center of dilation are not given in the problem.
Hence, The line n when dilated with the center of dilation on the line, it will bring no change on the original line.

Find the value of 0.7x0.08
Answer:
0.056
Step-by-step explanation:
For decimals, you just multiply, and the hundredths would stay, so the answer is 0.056, because 8 x 7 = 56!
Answer:
0.056
Step-by-step explanation:
7*8 is 56 right
looking at 0.7 how many numbers are before that dot
1 right which is seven
then 0.08 has how many digits before the dot thing
2 right which is 0 and 8
in total making three
then in 56 move three times forward from behind
1 5.6
2 0.56
3 0.056
and thats how we got this
dont confuse this technique with numbers like 0.80
the zero at the end of that number is not needed
that is to say that
0.80 = 0.8
when theres a zero at the back of a decimal its not counted
e.g
0.50= 0.5
0.4000000= 0.4

Complete the equation of the line whose slope is −2 y-intercept is (0,3)
Answer:
y=-2x+3
Step-by-step explanation:
hope this helps
Answer:
y = -2x + 3
Step-by-step explanation:
So you want to put it in the form y = mx + b where m is the slope and b is the y-intercept (an example of an equation in this form is y = 2x + 1).
It tells you that the slope is -2 and the y-intercept is at y = 3, so the equation would be:
y = -2x + 3
Solve the equation, and choose the type of solution you
found.
2x + 8 = 2(x + 4)
Answer:
All real numbers are solutions
Step-by-step explanation:
2x + 8 = 2(x + 4)
~Simplify right side
2x + 8 = 2x + 8
~Subtract 8 to both sides
2x = 2x
~Divide 2 to both sides
0 = 0
Best of Luck!
Answer: the answer is infinite
Step-by-step explanation: so first you need to distribute the 2 into the () and you would get 2x+8 and since it is the same on both sides it cancles eachother out therefore there is infinite answers

Answer:
as the cycle continues, you will always get 50 as the answer, since you are dividing both the numerator and the denominator with 10 in each expression. In other words, the 10:00 you divide the numerator which cancels out with the 10 you divide the denominator with. So the answer will always be 50 in each next expression.
Step-by-step explanation:
(I) 45÷90= 4500/90 = 50
(ii) 450÷9= 450/9 =50
(iii) 45÷0.9 = 45/0.9=50
(iv) 4.5 ÷ 0.09 = 45/0.09
starting with (I) 4500÷90 = 4500/90 =50
you divide the numerator and the denominator by 10 to get ; (ii) 450÷9 = 450/9 = 50
as the cycle continues you will always get 50 as the answer since you are dividing both the numerator and the denominator with 10 in each expression. In other words, the 10:00 you divide the numerator with cancels out with the 10 you divide the denominator with. So the answer will always be 50.
