Answer:
x = 3 + 2 sqrt3 Or 3 - 2 sqrt 3
Step-by-step explanation:
Solve for x:
1/5(5x + 12) = 18
Answer:
5x+12=18*5
5x=18*5-12
x=(18*5-12)/5
x=78/5
If fifteen workers did a job in eight hours, how long would it take five workers to do half of this job?
Answer:
2 i think
Step-by-step explanation:
(6 - 1) + (3m)i = -12 + 27i
Answer:
We want to solve the equation:
(6 - 1) + (3m)i = -12 + 27i
Where m is a complex number.
first, we can rewrite this as:
5 + 3*m*i = -12 + 27*i
3*m*i = -12 - 5 + 27*i
3*m*i = -17 + 27*i
And we can write m as:
m = a + b*i
Replacing that in the above equation we get:
3*(a + b*i)*i = -17 + 27*i
3*a*i + 3*b*i^2 = -17 + 27*i
and we know that i^2 = -1
3*a*i - 3*b = -17 + 27*i
The real part in the left (-3*b) must be equal to the real part in the right (-17)
then:
-3*b = -17
b = -17/-3 = 17/3
And the imaginary part in the left (3*a) must be equal to the imaginary part in the right (27)
then:
3*a = 27
a = 27/3.
Then the value of m is:
m = a + b*i = (27/3) + (17/3)*i

Answer:
y= -7
Step-by-step explanation:
So first distribute the 8
4=8y+32-4y
now combine like terms (the -4y+8y)
4=32+4y
Subtract 32 on both sides to isolate 4y
-28=4y
now divide 4 on both sides to isolate Y
-7=y
so y= -7

7x-6y=18 14x+9y=-27?
Answer: Hope this helped(tried my best thinking what the question was asking)
x=0
y=-3
Step-by-step explanation:
(Im going to add and subtract)
Add:
14x-12y=36
14x+9y=-27
28x-3y=9
Subtract:
-14x+12y=-36
14x+9y=-27
21y=-63
y=-3 (substitute in first equation)
7x+18=18
7x=0
x=0
SO
y=-3 and x=0

Answer:
The answer to the question provided is:
[tex] \frac{7}{4} [/tex]
Step-by-step explanation:
❃This what the slope formula looks like:
[tex]slope = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]
❃All we have to do is plug in:
[tex]slope = \frac{4 - ( - 3)}{6 - 2} = \frac{7}{4} [/tex]
❃Therefore, the slope is:

The Guinness book of world records states that the tallest trophy is about 270 inches. If they stacked 4 of those trophies on top of each other, how high would they be?
answer plz
Hey there!
If the tallest trophy is about 270 inches, and you stack 4 of those trophies on top of each other, you'd be multiplying 270 times 4.
270×4= 1,080
So, if you stacked four 270-inch trophies on top of each other, they would be 1,080 inches high.

original selling price of the house is $275,000. How much commission will Mrs. Cherry earn on this sale ?
Answer:
a commission of $7755
Step-by-step explanation:
original price = $275,000 x 0.94 = $258,500
258500 x 0.03 = $7755
Answer:
$7,755
Step-by-step explanation:
94% of $275,000 is $258,500
3% commission off that would be $7,755

what is 3x2 + 5x - x2 - 2x + 3 simplifyed completely
Answer:
2x^2+3x+3
Step-by-step explanation:
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2". 1 more similar replacement(s).
STEP 1
The Equation at the end of step 1
(3x2 + 5x) - x2) - 2x) + 3
STEP 2
Trying to factor by splitting the middle term
2.1 Factoring 2x2+3x+3
The first term is, 2x2 its coefficient is 2.
The middle term is, +3x its coefficient is 3.
The last term, "the constant", is +3
Step-1: Multiply the coefficient of the first term by the constant 2 • 3 = 6
Step-2: Find two factors of 6 whose sum equals the coefficient of the middle term, which is 3.
-6 + -1 = -7
-3 + -2 = -5
-2 + -3 = -5
-1 + -6 = -7
1 + 6 = 7
2 + 3 = 5
3 + 2 = 5
6 + 1 = 7
Observation: No two such factors can be found !!
Conclusion: Trinomial can not be factored
Final result :
2x^2 + 3x + 3
Hope this helps!

Answer:
The ordered pair that corresponds to point P is: (4, 2)
Step-by-step explanation:
It is clear from the graph that the point P is located at the location (4, 2).
In other words,
at x = 4, y = 2
It means:
The x-coordinate of the point P is: x = 4
The y-coordinate of the point P is: y = 2
Thus, the location of the point P → P(x, y) = P(4, 2)
Please check the attached graph.
Therefore, we conclude that:
The ordered pair that corresponds to point P is: (4, 2)

Un călător parcurge un drum în trei zile în prima zi merge o treime din drum și încă 15 km A doua zi parcurge două Septimi din rest iar în a treia zi ultimii 75 km Ce lungime are drumul
Answer:
Step-by-step explanation:
Fie distanța totală = x
Un călător parcurge un drum în trei zile
În prima zi merge o treime din drum și încă 15 km
= 1 / 3x + 15km
A doua zi călătorește două șapte din restul
= 2 / 7x
În a treia zi
75 km
Cât de lung este drumul
= 1 / 3x + 15 + 75 + 2/7 (2 / 3x).
