Solve for x:
7x = 105

Answer:

Step-by-step explanation:

you just need to add both equations

you will get 3y=12+6=18

3y=18

y=6

now replace y=6

3x+12=6

3x=6-12

3x=-6

x=-2

(-2,6)

Answer:

(-2,6)

Step-by-step explanation:

3x + 2y = 6

-3x + y = 12

3x + -3x = 0

2y + y = 3y

6 + 12 = 18

3y = 18

3y/3 = 18/3

y = 6

-3x + y = 12

-3x + 6 = 12

-3x = 12 - 6

-3x = 6

-3x/-3 = 6/-3

x = -2

Check the graph for proof

Answer:

Continuous

Step-by-step explanation:

The graph is considered continuous due to the fact that it can take any amount of height, weight, and temperature. If it was discrete there would be a limit to your hike.

Answer:

166m

Step-by-step explanation:

To calculate the area you multiply the length of all the pieces and add them to get. 4x5=20 then double that because there is 2 of those pieces and do the same for the rest of them. After all the multiplying you should get 40, 70, and 56 add them all up to get the answer

Answer:

The perimeter of the rectangle is 27n + 1 feet

Step-by-step explanation:

The formula of the perimeter of the rectangle is P = 2(L + W), where

∵ The width of a rectangle is 7n - 6.5 feet

∴ W = 7n - 6.5 feet

∵ The length of the rectangle is 6.5n + 7 feet

∴ L = 6.5n + 7 feet

→ Substitute W and L in the formula of the perimeter above

∵ P = 2[6.5n + 7 + 7n - 6.5]

→ Add the like terms

∴ P = 2[(6.5n + 7n) + (7 - 6.5)]

∴ P = 2[13.5n + 0.5]

→ Multiply the terms in the bracket by 2

∴ P = 27n + 1

∴ The perimeter of the rectangle is (27n + 1) feet

Answer:

[tex]in (y\sqrt{\frac{x}{y}}) =\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]

Step-by-step explanation:

From the question we are told that the expression [tex]ln(y √x/z[/tex]

[tex]in (y\sqrt{\frac{x}{y}})[/tex]

[tex]in(y)+in(y\sqrt{\frac{x}{y}})[/tex]

[tex]in(xy)=in(x)+in(y)[/tex]

[tex]in(xy)=in\frac{x}{z} ^1^/^2 +in(y)[/tex]

[tex]in(xy)=\frac{1}{2} in(\frac{x}{z}) +in(y)[/tex]

[tex]in(xy)=\frac{1}{2} in(x)-in(z) +in(y)[/tex]

[tex]in(xy)=\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]

Mathematically

[tex]in (y\sqrt{\frac{x}{y}}) =\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]

Step-by-step explanation:

Law of Indices: (a^m)^n = a^(mn).

Therefore (y⁴)² = y^(4*2) = y⁸.

Step-by-step explanation:

[tex] = ({y}^{4})^{2} \\ the \: power \: gets \: \: multipied \\ = ( {y})^{8} [/tex]

Answer:

Step-by-step explanation:

If you're asking for the area of the sector, it's the central angle of 360, times the area of the circle, for example, if the central angle is 60, and the two radiuses forming it are 20 inches, you would divide 60 by 360 to get 1/6.

The requried area of a sector bounded by a 180° arc is 8π square inches.

The area of a sector is a portion of the circle enclosed by two radii and an arc and is given by the formula A = (θ/360)πr², where θ is the angle in degrees and r is the radius of the circle.

Here,
The area of a sector bounded by a 180° arc in a circle with a radius of 4 inches can be found using the formula;

A = (θ/360)πr²

Where θ is the angle in degrees and r is the radius.
Since the angle is 180°, we have:

A = (180/360)π(4²) = 8π square inches.

Thus, the area of a sector bounded by a 180° arc is 8π square inches.

Answer:

We have the angles as;

8.9 and 72.2

Step-by-step explanation:

When two angles are complementary, they add up to 90

Let the first angle be x , the second angle is 72.2 degrees less and it is x-72.2

Thus, mathematically;

x + x - 72.2 = 90

2x = 90+ 72.2

2x = 162.2

x = 81.1

x = 81.1

The other will be

81.1 - 72.2 = 8.9

Answer:

0.625

Step-by-step explanation:

To solve the problem, we merely just divide the rates by each other. Ratios are just the fractions of two terms, after all.

Therefore, the answer would be 5/8, or 0.625.

To verify, we can use the other values given in your question.

10/16 is also an answer, but when you simplify, you get 5/8, which gives the same answer- 0.625.

You can do the same with the other ratios given.

15/24 simplified is 5/8, which, once again, is 0.625.

Thus, I can say with certainty that the answer is 0.625.

Answer:

The two will retain its unit place value

Step-by-step explanation:

We are given the number 506,092

Which is stated in words as

"Five hundred and six thousand and ninety two"

2 represents 2 units in the number

When we shift 2 by two places to the right, the number becomes

50,609,002

We can still see that "two" still retains it unit place value and the whole number now reads fifty million six hundred and nine thousand and 2

Step-by-step explanation:

When lines are parallel they travel side-by-side without ever crossing paths.

Answer: Parallel

Step-by-step explanation:

16. Length of a line = sqaureroot of ((x1-x0)^2 - (y1- y0)^2)

C (2,-3) D (6,3)

CD = sqaureroot of ((6-2)^2 + (3-(-3))^2)

CD = sqaureroot of ( 16 + 36)

CD = sqaureroot of 52 = 2 root 13 = length
