What is the solution to
this system of linear
equations?
Solve the system of linear equations. 3x−2y=1 9x−6y=3
solve for x: 2+x+x+x+4=9
Answer:
x=1
Step-by-step explanation:
2+1+1+1+4=9
2+x+x+x+4=9
=> 3x + 6 = 9
=> 3x = 9-6
=> 3x = 3
=> x = 3/3
=> x = 1

Answer:
P = 10x + 2
Step-by-step explanation:
Formula to find perimeter:
P = 2(l + w)
P = 2(4x + 1 + x)
P = 2(5x + 1)

One number is 60 more than another. If the larger number is divided by the smaller number, the quotient is 4.
What are the numbers?
Answer:
80 and 20
Step-by-step explanation:
Let the 1st no. be 'x'.
2nd no. should be 'x + 60'.
If the larger no.(x + 60) is divided by the smaller number(x), the quotient is 4.
=> (x + 60)/x = 4
=> x + 60 = 4x
=> 60=4x-x
=> 60=3x
=> 60/3 = x
=> 20 = x
No. are x = 20 and x+60 = 20+60= 80
In the interval 0° < x < 360°, find the values of x for which sin x = 0.6691 Give your answer tot he nearest degree
Answer:
x are 42 and 138degees
Step-by-step explanation:
Given the expression sin x = 0.6691
sin x = 0.6691
Take the sin inverse of both sides
sin⁻¹(sin x) = sin⁻¹(0.6691 )
x = sin⁻¹(0.6691 )
x = 41.99
x = 42 degrees (to the nearest degree)
Since sin theta is positive in the second quadrant;
x = 180 -theta
x = 180 - 42
x = 138degrees
Hence the value of x are 42 and 138degees

y = x + 5
Step-by-step explanation:
The output (y) is five more than the input (x)
and this is expressed symbolically as
y = x + 5
A teacher places 10 marbles in a bag.
- 2 blue marbles
- 3 red marbles
- 5 yellow marbles
A student draws one marble from the bag, does not replace it, then draws another marble from the bag. What is the probability that the first marble will be yellow and the second marble will be red?
Step-by-step explanation:
Since they do not replace it the total amount of marbles are the same

Answer:
45
Step-by-step explanation: 180- 135
Answer:
<L = 45
<N = 135
Step-by-step explanation:
<L + 135 = 180
<L = 180 - 135
<L = 45
<N = 135 because of vertical angles

2. a. - 1b.[tex] - \frac{2}{3} [/tex]3. a. 4b. 6Step-by-step explanation:
[tex]2. \: a. \: \sqrt[3]{ - 1} [/tex]
[tex] = \sqrt[3]{( - 1 )\times ( - 1 )\times( - 1)} [/tex]

[tex]b. \: \sqrt[3]{ - \frac{8}{27} } [/tex]
Since,
[tex] \sqrt[3]{ - x} = - \sqrt[3]{x} [/tex]
Hence,
[tex] = - \sqrt[3]{ \frac{8}{27} } [/tex]
[tex] = - \sqrt[3]{ \frac{2 \times 2 \times 2}{3 \times 3 \times 3} } [/tex]
[tex] = - \frac{2}{3} (ans)[/tex]
[tex]3. \: a. \: 10 - 2 \sqrt{9} [/tex]
[tex] = 10 - 2 \sqrt{3 \times 3} [/tex]
= 10 - 2 × 3
= 10 - 6
= 4 (Ans)
[tex]b. \: 70 - {( \sqrt[3]{64} )}^{3} [/tex]
[tex] = 70 - \sqrt[3]{ {64}^{3} } [/tex]
[tex] = 70 - \sqrt[3]{64 \times 64 \times 64} [/tex]

whats the slope using Rise/Run?
thanks, if you help
Answer:
the slope of the given line is m = rise / run = -1/2
Step-by-step explanation:
Going from (1, -1) to (3, -2), the 'rise' is actually a drop of 1 unit; the 'run' is +2.
Thus, the slope of the given line is m = rise / run = -1/2
Two observers are standing on shore ½ mile apart at points A and B and measure the angle to a sailboat at a point C at the same time. Angle A is 63° and angle B is 56°. Find the distance from each observer to the sailboat. Round to the nearest hundredth of a mile.
Answer:
Step-by-step explanation:
The length 0.51 miles and 0.47 miles are the distances from each observer to the sailboat.
What is the Sine Rule?The Law of Sines (also called the Sine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.
Triangle is a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry.
As per the given question, the given data as:
A = 63
B = 56
C = 61 (because these angles should add up to 180)
c = 1/2
We know that the Sine Rule,
sin 63 / a = sin 61 / .5
a = 0.51 miles
sin 56 / b = sin 61 / .5
b = 0.47 miles
Therefore, the length 0.51 miles and 0.47 miles are the distances from each observer to the sailboat.

A triangle prism has a volume of 240m3.The area of the base is 16m2 what's is the height of the triangle prism
Answer:
The height is 45 m
Step-by-step explanation:
The volume of a triangular prism is V = (1/3)(area of base)(height)
If the voume is 240 m^3 and the area of the base 16 m^2, then the height of the prism is determined as follows:
3V = (area of base)(height)
Dividing both sides by (area of the base), we get:
3(240m^3)
height = ------------------------- = 45 m
16 m^2
