When you multiply a number by 6 and subtract 5m the product ,you get 7. find the number.
with solution
Answer:
x = 2
Step-by-step explanation:
Let the number be x
When we multiply a number by 6 and subtract it by 5, we would get 7.
On multiplication of number x with 6 it will be 6x.12
On subtraction of 5 it will be 6x - 5
6x - 5 = 7
6x = 7 + 5
6x = 12
x = 12/6
x = 2
Answer:
The number is 2
Step-by-step explanation:
Let the number be n
Multiply the number by 6 = 6n
Subtract 5 from the number , 6n - 5
And we get 7
So , the expression : 6n - 5 = 7
6n = 7 + 5
6n = 12
n = 2
Marinas bill for dinner totals $38.65, including tax. She leaves a 20% tip. How much is Marinas total? (pls hurry i’m in summer school rn and i need the answer)
9514 1404 393
Answer:
$46.38
Step-by-step explanation:
When a 20% tip is added to the bill, the result is the bill being multiplied by a factor of (1 + 20%) = 1.20.
1.20 × 38.65 = 46.38
Marina's total with the tip is $46.38.

The probability that at least one number is odd and the sum of the two numbers is even is
v . The probability that exactly one
number is 6 and the product of the two numbers is at most 15 is
Step-by-step explanation:
There are 36 equally likely pairs: (1,1);(1,2);(1,3),…(6,4);(6,5);(6,6). The corresponding sums: 2,3,4,….10,11,12. are best observed with an addition table for 1-6 with 1-6. 3 is simple enough because only (1,2) and (2,1) can sum to 3. So P= 2/36 = 1/18. P(SUM =4) = 3/36 because (1,3);(2,2);(3,1) are the only pairs that sum to 4. The best way to see this is look at the first die. To get a sum of 4, the first die must be 1,2 or 3. Each of those first rolls forces one outcome for the second die. P(10) = 3/36 because the first die must be 4,5,or6.
which line on the graph represents the equation y=3x-2
line b
line a
line d
line c
Answer:
Line A.
Step-by-step explanation:
When you put x as zero into 3x-2, you get 3(0)-2. That equals -2. Therefore, y = -2. When x=0, that is the y-intercept, so the y-intercept is -2. Line A crosses the y-axis at -2, so line A has that y-intercept.
Slope is always y/x. On a graph, that is the number of squares UP over the number of squares ACROSS. Counting, we get, 3 squares up over 1 square across for line A. 3/1= 3. The slope is the number we multiply by x. In the equation, that is 3, because we see 3x, and no sign or space between 2 numbers automatically means we multiply. So line A also has the correct slope.
In linear equations (straight lines), the same slope and y-intercept are enough to tell you that the equation matches the line.
Therefore, the answer is A!

Help find the perimeter and area
Answer:
P =33.6 m
A = 70.56 m^2
Step-by-step explanation:
The perimeter of a square is given by
P =4s = 4(8.4) =33.6 m
The area of a square is given by
A = s^2 = (8.4) ^2 =70.56 m^2
Answer:
Perimeter = 8.4×4 = 33.6 meters
Area = 8.4^2 = 70.56 square meters

[Pre-Calc] Please Help! I don’t know where to start. How do I do this?
Answer:
See Below.
Step-by-step explanation:
Problem A)
We have:
[tex]\displaystyle \csc^2\theta \tan^2\theta -1=\tan^2\theta[/tex]
When in doubt, convert all reciprocal trig functions and tangent into terms of sine and cosine.
So, let cscθ = 1/sinθ and tanθ = sinθ/cosθ. Hence:
[tex]\displaystyle \left(\frac{1}{\sin^2\theta}\right)\left(\frac{\sin^2\theta}{\cos^2\theta}\right)-1=\tan^2\theta[/tex]
Cancel:
[tex]\displaystyle \frac{1}{\cos^2\theta}-1=\tan^2\theta[/tex]
Let 1/cosθ = secθ:
[tex]\sec^2\theta -1=\tan^2\theta[/tex]
From the Pythagorean Identity, we know that tan²θ + 1 = sec²θ. Hence, sec²θ - 1 = tan²θ:
[tex]\tan^2\theta =\tan^2\theta[/tex]
Problem B)
We have:
[tex]\sin^3x=\sin x-\sin x \cos^2 x[/tex]
Factor out a sine:
[tex]\sin x(\sin^2 x)=\sin x-\sin x\cos^2 x[/tex]
From the Pythagorean Identity, sin²θ + cos²θ = 1. Hence, sin²θ = 1 - cos²θ:
[tex]\sin x(1-\cos^2 x)=\sin x-\sin x\cos^2x[/tex]
Distribute:
[tex]\sin x- \sin x \cos^2 x=\sin x-\sin x\cos^2 x[/tex]
Problem C)
We have:
[tex]\displaystyle \frac{\cos 2x+1}{\sin 2x}=\cot x[/tex]
Recall that cos2θ = cos²θ - sin²θ and that sin2θ = 2sinθcosθ. Hence:
[tex]\displaystyle \frac{\cos^2 x-\sin^2 x+1}{2\sin x\cos x}=\cot x[/tex]
From the Pythagorean Identity, sin²θ + cos²θ = 1 so cos²θ = 1 - sin²θ:
[tex]\displaystyle \frac{2\cos^2 x}{2\sin x\cos x}=\cot x[/tex]
Cancel:
[tex]\displaystyle \frac{\cos x}{\sin x}=\cot x[/tex]
By definition:
[tex]\cot x = \cot x[/tex]

substituting the equation x=4y - 12 into the equation -2y= x- 6. will produce what equation?
Step-by-step explanation:
Given that,
x=4y - 12 ....(1)
And
-2y= x- 6 ....(2)
Put equation (1) in equation (2). So,
-2y= (4y - 12)- 6
-2y = 4y - 12 -6
-2y-4y = -12-6
-6y = -18
y = 3
So, substituting x=4y - 12 into the equation -2y= x- 6 will produce y = 3.

What is the slope of a line perpendicular to the line y=2x+5 ?What is the slope of a line perpendicular to the line y=2x+5 ?
1/2

−1/2
Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
Hi there!
In the given equation [tex]y=2x+5[/tex], the slope of the line is 2.
Perpendicular lines always have slopes that are negative reciprocals, like negative "flipped" fractions.
Example: The negative reciprocal of [tex]\frac{3}{1}[/tex] (which is the same as 3) is [tex]-\frac{1}{3}[/tex].
Example 2: The negative reciprocal of [tex]-\frac{4}{3}[/tex] is [tex]\frac{3}{4}[/tex].
Using this logic, the negative reciprocal of 2, or [tex]\frac{2}{1}[/tex], is [tex]-\frac{1}{2}[/tex]. Therefore, the slope of a line perpendicular to the line [tex]y=2x+5[/tex] is [tex]-\frac{1}{2}[/tex].

Solve the equation by factoring. 3x^2-5x-12=0
Answer:
x = 3
[tex]x=-1\frac{1}{3}[/tex] or [tex]x=-\frac{4}{3}[/tex]
Step-by-step explanation:
3x² - 5x - 12 = 0
Method 1: Factoring
3x² + 4x - 9x - 12 = 0
(3x² + 4x) + (- 9x - 12) = 0
x(3x + 4) - 3(3x + 4) = 0
(x - 3)(3x + 4) = 0
Two separate equations
x - 3 = 0
3x + 4 = 0
x - 3 = 0
x - 3 + 3 = 0 + 3
3x + 4 = 0
3x + 4 - 4 = 0 - 4
3x = - 4

Method 2: Quadratic Formula
Ignore the A before the ±, it wouldn't let me type it correctly.

3x² - 5x - 12 = 0
a = 3
b = - 5
c = - 12
[tex]x=\frac{-(-5)±\sqrt{(-5)^{2} -4((3)(-12))} }{2(3)}[/tex]
[tex]x=\frac{-(-5)±\sqrt{25 -4((3)(-12))} }{2(3)}[/tex]
[tex]x=\frac{-(-5)±\sqrt{25 +144} }{2(3)}[/tex]
[tex]x=\frac{-(-5)±\sqrt{169} }{2(3)}[/tex]
[tex]x=\frac{-(-5)±13}{2(3)}[/tex]
[tex]x=\frac{5±13}{6}[/tex]
Two separate equations
One must have a + (positive) and the other will have a - (negative).
[tex]x=\frac{5+13}{6}[/tex]
[tex]x=\frac{18}{6}[/tex]
x = 18 ÷ 6
x = 3
[tex]x=\frac{5-13}{6}[/tex]
[tex]x=\frac{-8}{6}[/tex]
x = - 8 ÷ 6
[tex]x=-1\frac{1}{3}[/tex]
