Step-by-step explanation:

..

Answer:

X=3, y=5

Step-by-step explanation:

3x + y = 14 equation 1

y=5 equation 2

3x + 5 = 14.    substitute value of y from equation 2 into equation 1

3x=9

x-3

Answer:

X=-4, y=-7

Step-by-step explanation:

6x-5y=11.     1st equation

y=7x+21    2nd equation

6x-5(7x+21)=11. Sub value of y in 2nd equation (7x+22) into 1st equation

6x-35x-105=11. Solve by distributative property

-29x-105=11.   Add x values

-29x=116.         add 105 to both sides

x=-4.                Solve for x

solve for y:

y=7x+21

y=7(-4)+21

y=-28+21

y=-7

check answer by substituting x and y into either equation

6x-5y=11

6(-4)-5(-7)=11

-24+35=11

11=11

Answer:

x - 3.8 = y

Step-by-step explanation:

3.8 - 3.8 = 0

4.2 - 3.8 = 0.4

5.1 - 3.8 = 1.3

7.3 - 3.8 = 3.5

Answer:

10 feet

Step-by-step explanation:

pythagorean theorem

Answer:

Hypotenuse = 10.

Step-by-step explanation:

h^2 = 6^2 + 8^2

= 36 + 64

= 100

So h= 10.

Answer:

314.16 ft²

Step-by-step explanation:

The flower garden is circular is shape.

To solve for this question, we have to find the area of the circular flower bed

The formula is given as

= πr²

Hence,

= π × 10²

= 314.15926536 ft²

Approximately = 314.16ft²

Therefore, 314.16ft² of plastic is needed

Answer:

It really all depends on how much percent of your grade the test is worth. If your current average is 77%, and the test is worth 30-100% of your grade, then the 77% will likely become 75% or even 73%.

Step-by-step explanation:

It all just depends.

The volume of the triangular prism is 1360 cubic centimeters, which is option G.

A triangular prism is a three-dimensional geometric shape that consists of two parallel triangular bases and three rectangular faces. It has six faces, nine edges, and six vertices. The volume of a triangular prism is found by multiplying the area of the base triangle by the height of the prism.

V = A * height

To find the volume of a triangular prism, we need to multiply the area of the base (a triangle) by the height of the prism. The area of a triangle is given by the formula:

A = (1/2) * base * height

In this case, the base of the triangle is 10 cm and the height is 8 cm, so:

A = (1/2) * 10 cm * 8 cm

A = 40 cm²

Therefore, the volume of the prism is:

V = A * height

V = 40 cm² * 34 cm

V = 1360 cm³

So, the volume of the triangular prism is 1360 cubic centimeters, which is option G.

Answer:

[tex]5.11 \times {10}^{3} \\ = 5.11 \times 1000 \\ = 5110[/tex]

Answer:

5110

Step-by-step explanation:

In order to solve this, we need to know what a "power" in math is, and then we just do the following...

[tex](5.11)(10^{3}) = (5.11)(1000) = 5110[/tex]

Answer:

6.65 kilometers

Step-by-step explanation:

950 * 7 days a week = 6650 meters

6650 meters / 1000 (conversion to kilometers) = 6.65 kilometers

Answer:

6.65  km

Step-by-step explanation:

Let's solve this in a set of fraction forms. Since 1 day is 950 meters, 1 week will be converted to days to be on equal grounds. 1 week = 7 days. Therefore, let us set up a fraction; Let "x" be the variable

[tex]\frac{950}{1}=\frac{x}{7}[/tex]

Step 1: Switch sides

[tex]\frac{x}{7}=\frac{950}{1}[/tex]

Step 2: Apply rule [tex]\frac{a}{1}=a[/tex]

[tex]\frac{x}{7}=950[/tex]

Step 3: Multiply both sides by 7

[tex]\frac{7x}{7}=950\cdot \:7[/tex]

Step 4: Simplify

[tex]x=6650[/tex]

Expressed: [tex]\frac{6650 meters}{1000}[/tex] (convertion to kilometers) = 6.65 kilometers

Therefore, Janet would walk 6.65 km in an entire week
