What’s the solution for this 4(1-x)+2x=-3(x+1). ?
Answer: x = -7
Step-by-step explanation:
4(1 - x) + 2x = -3(x + 1)
First, use distributive property
4 - 4x + 2x = -3x + -3
Combine like terms
4 - 2x = -3x - 3
Add 3x to each side
4 + x = -3
Subtract 4 from each side
x = -7
Answer:
-2
Step-by-step explanation:1. Equation at the end of step 1 ((4•(1-x))+3x)-(0-2•(x-1)) = 0
2. Equation at the end of step 2 (4 • (1 - x) + 3x) - -2 • (x - 1) = 0
3. Equation at the end of step 3 x + 2 = 0
4. End of equation Solve : x+2 = 0

Todd swam three trials of the 50-meter freestyle. His time was 32.15 seconds for the first trial, 31.67 seconds for the second trial, and 30.55 seconds for the third trial. Part A What is Todd's combined time for all three trials? Enter your answer in the box. seconds Part B How much faster was Todd's second trial than his first trial? Enter your answer in the box. second(s)
Answer:
A. 94.37 seconds
B. 0.48 seconds
Step-by-step explanation:
Total distance = 50 meters
First trial = 32.15 seconds
Second trial = 31.67 seconds
Third trial = 30.55 seconds
A. What is Todd's combined time for all three trials
Todd's combined time for the three trials = First trial + Second trial + Third trial
= 32.15 seconds + 31.67 seconds + 30.55 seconds
= 94.37 seconds
B. How much faster was Todd's second trial than his first trial?
Second trial = 31.67 seconds
First trial = 32.15 seconds
Time taken for first trial - Time taken for second trial -
= 32.15 seconds - 31.67 seconds
= 0.48 seconds
Todd's second trial was 0.48 seconds faster than his first trial
Let logp/n=5 and logm/n=9
Answer:
we know that
log (P/N) = log P - log N
so
log P - log N = 5----------------> equation 1
log (M/N) = log M - log N
so
log M - log N = 9 ------------------> equation 2
If you subtract equation 2 from equation 1,
you have
log M - log P = 4
That means that log (M/P) = 4 ----> 10^4 = M/P ---> M = 10000P
the answer is
the relationship between P and M is
M = 10000P
Help me find the X! UwU..
Well all the angles in a triangle add up too 180º and this triangle is obviously a equilateral triangle (all sides are same) BUT as you see the other people saying X = 60º notice that it says 2 xº meaning that it is X x 2 so 60º is actually wrong :).
If it is X is 60º (since the 3 angles add together since it’s equilateral) then that would be 2 x 60º = 120º times 3 WHICH IS NOT 180.I think U get what I mean now,it’s 2 Xº; so X is 30 because 30 x 2 = 60º and 60 x 3 = 180º!
So Da Answer is X = 30º
Hope this helped :)

Write the slope of a line perpendicular to y=-6x+4. Explain why it is perpendicular
Answer:
1/6 is the slope since you have to flip it
Step-by-step explanation:
Answer:
The slope of a line perpendicular to the equation is 1/6 or x/6.This is perpendicular because it is the reciprical of the other equation
Step-by-step explanation:
y=-6x+4.
the slope intercept form is y=mx+b
m is the slope
m=-6
for the equation to be perpendicular then the slope is the reciprical
Knowing this lets find a line perpendicular to this equation
Equation:
y=1/6x+2/3
or
y=x/6+2/3

After being dilated by a scale factor 1.5?
Given:
The given figure is dilated by a scale factor 1.5.
To find:
The coordinates of B' and C'.
Solution:
If a figure is dilated by a scale factor k at point (a,b), so the rule of transformation is
[tex](x,y)\to (k(x-a)+a,k(x-b)+b)[/tex]
From the given figure it is clear that A(3,-3), B(-2,2) and C(-3,-5).
The figure is dilated by a scale factor 1.5 at point A(3,-3), so the rule of transformation is
[tex](x,y)\to (1.5(x-3)+3,1.5(x-(-3))+(-3))[/tex]
[tex](x,y)\to (1.5(x-3)+3,1.5(x+3)+(-3))[/tex]
[tex](x,y)\to (1.5(x)-4.5+3,1.5(x)+4.5-3)[/tex]
[tex](x,y)\to (1.5x-1.5,1.5x+1.5)[/tex]
Using this rule, we get
[tex]B(-2,2)\to B'(1.5(-2)-1.5,1.5(2)+1.5)[/tex]
[tex]B(-2,2)\to B'(-3-1.5,3+1.5)[/tex]
[tex]B(-2,2)\to B'(-4.5,4.5)[/tex]
And
[tex]C(-3,-5)\to C'(1.5(-3)-1.5,1.5(-5)+1.5)[/tex]
[tex]C(-2,2)\to C'(-4.5-1.5,-7.5+1.5)[/tex]
[tex]C(-2,2)\to C'(-6,-6)[/tex]
Therefore, the coordinates of B' and C' are B(-4.5,4.5) and C'(-6,-6).

c. 13 + 9x2 + 4
d. 4r - 13.rº + 9
Answer:
a. 4x³+13x²+9
Step-by-step explanation:
1. Distribute 4x to every term in the second set of parenthesis to get:
4x³-16x²+12x
2. Distribute 3 to every term in the second set of parenthesis to get:
3x²-12x+9
3. Add/subtract terms with the same variables/degrees:
4x³-16x²+12x+3x²-12x+9
4. The simplified answer is:
4x³+13x²+9
Answer:
4x³ - 13x² + 9
Step-by-step explanation:
(4x + 3)(x² - 4x + 3) =
(4x)(x²) + (4x)( - 4x) + (4x)(3) + 3(x²) + 3( - 4x) + 3(3) =
4x³ - 16x² + 12x + 3x² - 12x + 9 =
= 4x³ - 13x² + 9

A tile backsplash is being installed. The installation fee is $150.00. The title is priced at $2.75 per square foot, f. Which equation best represents the total cost, c, of the backsplash
A. c = 150f + 2.75
B. c = 2.75 - 150f
C. c = 2.75 + 150
D. c = 152.75f
Answer:
c = 2.75f + 150Step-by-step explanation:
The installation fee is one off payment and tiles price depends on the area, so the total price for f square foot tile is:
c = 2.75f + 150It seems to be the option C but there is a typo (missing f)
Answer:
c = 2.75f + 150Given:
Installation fee is $150.00The title is priced at 2.75 square footOption C represents the answer.
Answer - c = 2.75f + 150
x+8y
units
8x -x+5y units
what’s the perimeter?
Answer:
P = 16x+26y units
Step-by-step explanation:
Let the length is (x+8y) units
Width = (8x-x+5y) units
We need to find the perimeter. We know that the perimeter is equal to the sum of all sides.
P = 2[(x+8y) + (8x-x+5y)]
= 2[(8x+8y+5y)]
= 2[8x+13y]
= 16x+26y
Hence, the required perimeter is 16x+26y.

Emilio has 2 quarters, 4 dimes, 3 nickels and 5 pennies. How much money does Emilio have in all?
Answer:
$1.10
Step-by-step explanation:
What we know:
Emilio has 2 quarters, 4 dimes, 3 nickels, and 5 pennies.
Quarters = 0.25 * 2
Dimes = 0.1 * 4
Nickels = 0.05 * 3
Pennies = 0.01 * 5
$0.50 + $0.40 + $0.15 + $0.05
$0.90 + $0.20 = $1.10 in total
Rearrange w=3(2a+b)-4 to make a the subject
Answer:
a=[tex]\frac{-1}{2}[/tex]b+[tex]\frac{2}{3}[/tex]+[tex]\frac{1}{6}[/tex]w
Step-by-step explanation:
Original equation: w=3(2a+b)-4
1. Distribute the 3 to the numbers inside parenthesis to get:
w=6a+3b-4
2. Subtract 6a from both sides to get:
-6a+w=3b-4
3. Subtract w from both sides to get:
-6a=3b-4-w
4. Divide both sides by -6 and simplify to get:
a=[tex]\frac{-1}{2}[/tex]b+[tex]\frac{2}{3}[/tex]+[tex]\frac{1}{6}[/tex]w

Given m|n, find the value of x.
t
(6x+10)
(5x+28)
line m || line n
To Find:The value of x.
Alternate Interior Angles:The angles formed when a transversal intersects two parallel lines ( m and n ).
Explanation:6x + 10° = 5x + 28° ( Alternate Interior Angles )
By transposition method, we get
6x - 5x = 28° - 10°
By simplifying the like terms, we get
x = 18°
Answer:The value of x is 18°.
Tristan rode his bike for 9 kilometers. One mile is approx. equal to 1.6 kilometers. Which measurement is closest to the numbers of miles Tristan rode his bike?
A. 5.625 mi
B. 2.8 mi
C. 6.4 mi
D. 4.4
Answer: A.
Step-by-step explanation: First you must think about how many miles is 9 kilometers. How many miles in 9 kilometers is 5.59234. And A is the closest to the numbers of miles Tristan rode his bike. The other questions would be wrong. It isn't the exact one because it's the closest, not exact. Hope that helps :).
Find the equation of line that passes through the points (2.0) and (4.6). Write the equation in slope-intercept form
Answer:
y = 3x - 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 0) and (x₂, y₂ ) = (4, 6)
m = [tex]\frac{6-0}{4-2}[/tex] = [tex]\frac{6}{2}[/tex] = 3, then
y = 3x + c ← is the partial equation
To find c, substitute either of the 2 points into the partial equation
Using (2, 0 ) , then
0 = 6 + c ⇒ c = 0 - 6 = - 6
y = 3x - 6 ← equation of line

Answer:
m = 2
Step-by-step explanation:
The given equation is :
8x – 4y - 9 = 0
The general equation of a line is given by :
y = mx+b ...(1)
here m is slope and b is y-intercept
Equation (1) can be written as :
8x – 4y = 9
Dividing both sides by (-4)
[tex]\dfrac{8x}{-4}-\dfrac{4y}{-4}=\dfrac{9}{-4}\\\\-2x+y=-\dfrac{9}{4}\\\\y=2x+\dfrac{-9}{4}[/tex] ...(2)
Comparing equation (1) and (2), we get :
m = 2
Hence, the slope of the line is 2.
