Answer:
x = 4
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
6*x-9-(2*x+7)=0
Pull out like factors :
4x - 16 = 4 • (x - 4)
Solve : 4 = 0
Add 4 to both sides of the equation :
x = 4
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
Step-by-step explanation:
and your answer is x=4
In the equation 3x - 5 = 22,
where "x is the cost of a sandwich"
Diana said that "the sandwich cost $9."
Victor's answer is $5.
Who is right? Support your claim with math evidence or reasoning.
Answer:
Diana said that "the sandwich cost $9
Step-by-step explanation:
3x - 5 = 22
3x = 22 + 5
3x = 27
x = 27 / 3
x = 9
4 + 4x = -5(x - 8)
Solve Multi-Step equation.
Please explain how you i can understand too!
Answer:
If solving for x its
4 + 4x = -5(x - 8) (side math --> -5x +40)
-4. = -4
4x = -5x + 36
+5x = +5x
9x = 36
÷ ÷ (by 9)
x = 4

How do you solve these two problems please explain step by step
Answer:
1) [tex]x=15, y=41[/tex]
2) [tex]x=6, y=24[/tex]
Step-by-step explanation:
1)
The two triangles are similar by AA similarity.
That means [tex]5x-5=4x+10[/tex].
We can add [tex]5[/tex] to both sides to get [tex]5x=4x+15[/tex].
We can then subtract [tex]4x[/tex] from both sides to get [tex]x=15[/tex].
We know that the [tex](5x-5)+(6y-4)=180[/tex] because they both lie on a straight line.
We can plug in for [tex]x[/tex] to get [tex](5(15)-5)+(6y-4)=75-5+6y-4=6y-66=180[/tex].
We can divide both sides of the equation by [tex]6[/tex] to get [tex]y-11=30[/tex].
We then add [tex]11[/tex] to both sides to get [tex]y=41[/tex].
So, [tex]\boxed{x=15, y=41}[/tex] and we're done!
2)
Because the two bases of a trapezoid are parallel, meaning adjacent top and bottom angles sum to [tex]180^{\circ}[/tex], we have that [tex]90+3y+18=180[/tex].
We can subtract a [tex]90[/tex] and an [tex]18[/tex] from both sides to get [tex]3y=72[/tex].
We then divide both sides of the equation by [tex]3[/tex] to get [tex]y=24[/tex].
We do the same thing for [tex]x[/tex]. On the other side of the trapezoid, we have that [tex]15x+30+10x=180[/tex].
We combine like terms on the left side to get [tex]25x+30=180[/tex].
We subtract a [tex]30[/tex] from both sides to get [tex]25x=150[/tex].
We divide both sides of the equation to get [tex]x=6[/tex].
So, [tex]\boxed{x=6, y=24}[/tex] and we're done!

A number is multiplied by 3. Next, 6 is added to the product. Then, the sum is divided by 8. If the result is 6, what is the number?
Answer:
14
Step-by-step explanation:
14 x 3 = 42
42 + 6 = 48
48 ÷ 8 = 6
Therefore, the answer is 14.
Answer:
14
Step-by-step explanation:
let us call the number x for now
the number (x) is multiplied by 3 to give us
3x
then,
it is added to 6 to give
3x + 6
then, our sum is divided by 8:
(3x + 6) / 8
according to the question, the result is 6
therefore,
3x + 6 / 8 = 6
if we cross multiply,
3x + 6 = 8 ( 6 )
3x + 6 = 48
collecting like terms,
3x = 48 - 6
3x = 42
divide through by 3 to give
3x / 3 = 42 / 3
x = 14
therefore, x = 14
to reassure us of our answer,
since (3(x) + 6) / 8 = 6
and we know that x = 14,
therefore,
(3(14) + 6) / 8 = 6
(42 + 6) / 8 = 6
48 / 8 = 6
6 = 6
therefore, we are now sure that x = 14
hope this helps

Shannon says that the lines y=-3x-4, y = -x + 6, y = -4x - 5, and y=-x-5 could represent the sides of a rectangle. Explain Shannon's error.
The adjacent sides of rectangle form 90° to each other or are
perpendicular, while the opposite sides are parallel.
The error, is that the coefficient of x, in the four equations can only take on two values, such that if one of the values is m, the other will be [tex]-\dfrac{1}{m}[/tex]
Reasons:
In a rectangle, the adjacent sides are perpendicular to each other, while
the opposite sides are parallel.
The slope of parallel lines are equal, and the slope, of a line perpendicular to another line with slope, m, is [tex]-\dfrac{1}{m}[/tex], therefore the slopes of the parallel sides should be equal, which gives;
The equations should consist of two pairs of equations of lines with equal slopes, such as the pair, y = -x + 6, and y = -x - 5The slope of the other two lines should therefore be [tex]-\dfrac{1}{-1} = 1[/tex], which gives the equations of the other two lines as y = x - 4, and y = x - 5, respectively.Therefore;

prove that 5^(2n - 1) is divisible by 8
Your teacher must have made a typo somewhere. The expression 5^(2n-1) is not divisible by 8.
The expression 5^(2n-1) is composed of 2n-1 copies of "5" multiplied together. The key here is that 5 is the only unique prime factor of this number.
On the other hand, 8 = 2*2*2 = 2^3 showing that 2 is the only prime factor for this number. At this point, we can see that there's no way that 5^(2n-1) is divisible by 8. It all comes down to the clash of the primes 5 and 2 not matching up, and having nothing in common.
Let's consider a few concrete examples:
If n = 1, then 5^(2n-1) = 5^(2*1-1) = 5^1 = 5 which is not divisible by 8. The number 5/8 = 0.625 isn't an integer.If n = 2, then 5^(2n-1) = 5^(2*2-1) = 5^3 = 125 which is also not a multiple of 8. The number 125/8 = 15.625 isn't an integer.I'll let you try other natural numbers for n, and you'll find that [tex]\frac{5^{2n-1}}{8}[/tex] isn't an integer.

A car is traveling at 40 mi/hour. What is the car's speed in feet per second?
Answer:
58.8 feet per second
Step-by-step explanation:
At 40 miles per hour, you are traveling 58.8 feet per second. To convert miles per hour to feet per second, multiply the miles per hour figure by 1.47. There are 5280 Feet in a mile and 3600 Seconds in an hour. If you divide 5280 Feet by 3600 Seconds (5280 FT /3600 SEC.), you get 1.47.

JL has endpoints J(8,10) and L(20,5). Point K has coordinates (13,9). What is the length of JL?
The length of line JL which has endpoints J(8,10) and L(20,5) is; JL = 13.
According to the question, we are required to determine the length of line JL.
However, the coordinates of the end points of line JL are given as;
Point J; (8,10)Point L; (20,5).The length of line JL is given by Pythagoras theorem as;
JL = √(20-8)² + (5-10)²JL = √ 12² + (-5)²JL = √ 144 + 25JL = √169JL = 13.
Therefore, the length of line JL which has endpoints J(8,10) and L(20,5) is; JL = 13.
