Answer:

-8/5 + 2x = y

Step-by-step explanation:

-8=-10x + 5y

Add 10x to each side

-8+10x=-10x+10x + 5y

-8+10x = 5y

Divide each side by 5

-8/5  + 10x/5 = 5y/5

-8/5 + 2x = y

[tex]\sf\dashrightarrow -8=-10x + 5y [/tex]

[tex]\sf\implies -8=5(2x+y)[/tex]

[tex]\sf\implies \dfrac{-8}{5}=-2x+y [/tex]

[tex]\sf\implies \dfrac{-8}{5}+2x=y[/tex]

figure b, it's rectangle.so length×width

=7×17

=119

area of the shape=153+119

=272cm squared

Answer:

D.    272 cm²

Step-by-step explanation:

will make it easy and short

use the area of a trapezoid = (a + b) * h/2

where a = 25,  b = 7,  h = 17

Area = (25 + 7) * (17/2)

Area = 32 * 8.5

Area = 272 cm²

Answer:

21 packets bought, 10 packets free

Step-by-step explanation:

To find the cost of planting grass , we have to find area of the field.

Area of field = Length × Breadth

[tex]{= 300×170}[/tex]

[tex]{=51000 sq. m}[/tex]

Now convert into hectare.

1 hectare = 10000m sq.

51000 / 10000

So area field = 5.1 hectare sq.

Now cost = 5.1 x 0.80 p

[tex]{= 0.408 p}[/tex]

Answer:

$9600.72

Step-by-step explanation:

Area of the field = length × width

Length = 1,021 feet

Width= 725 feet

Area of the field = length × width

= 1,021 feet × 725 feet

= 740,225 square feet

One bag covers 1000 square feet

There are 740,225 square feet

Find the number of bags that will cover the total of 740,225 square feet

Total bags = 740,225 / 10000

=740.225 bags

A bag cost $12.97

Total cost of 740.225 bags= 740.225 × 12.97

= $9600. 71825

Approximately

$9600.72

Floor ride up to = 13 floor

Step-by-step explanation:

Given:

Parking garage = 4 floors under ground

Elevator up-to = 17 floor

Find:

Floor ride up to

Computation:

Floor ride up to = Elevator up-to - Parking garage

Floor ride up to = 17 floor - 4 floor

Floor ride up to = 13 floor

Answer:

x = -2

Step-by-step explanation:

3(3 - x) = 5(2x + 7) multiply 3 with both 3 and -x then 5 with 2x and 7

9 - 3x = 10x + 35 add like terms

9 - 35 = 10x + 3x

-26 = 13x

Answer: Volume of a sphere = 4/3 * pi * r^3       r = radius of sphere      pi~ 3.14

Step-by-step explanation: If you use the radius in inches, your result will be in cubic inches (in^3)

The amount of water in cubic inches, that Mya's exercise ball will hold is 904.779 in³.

The volume of a sphere is the volume of space occupied by a sphere.  It is given by the formula:

[tex]\text{Volume of Sphere} = \dfrac{4}{3}\pi r^3[/tex]

As it is given that the diameter of Mya's ball is 12 inches, also we know that the volume of a sphere is given by the formula,

[tex]\text{Volume of Sphere} = \dfrac{4}{3}\pi r^3[/tex]

As we know that the diameter of Mya's ball is 12 inches, therefore, the radius of Mya's ball can be written as,

[tex]\rm Radius = \dfrac{Diameter}{2} = \dfrac{12\ in}{2} = 6\ in.[/tex]

Now, if we substitute the value of the radius of Mya's ball in the formula of the volume of the ball,

[tex]\rm \text{Volume of Ball} = \dfrac{4}{3}\times \pi \times 6^3 = 904.779\ in^3[/tex]

Hence, the amount of water in cubic inches, that Mya's exercise ball will hold is 904.779 in³.

Sol: importance: mathematics can be tricky, so precise definitions are essential. Without them, there can be confusion, which will generate the wrong answer more often than not.  It teaches the students exactly how to use formulas and under what condition a mathematical statement is true.

Some words related to geometry that are quite hard to define precisely are the line, the plane, and the point. In mathematics, the unit square is area one and any other shape.

Answer:

50sq cm

Answer:

Domain is the set of all x values, the independent quantity, for which the function f(x) exists or is defined.

Step-by-step explanation:

i just graphed it

Answer:

Domain:

[tex]x\in\mathbb{R}[/tex]

Range:

[tex]y\geq -5[/tex]

Step-by-step explanation:

The domain is the span of x-values covered by the graph, and the range is the span of y-values covered by the graph.

From the graph, we can see that the x-values covered by the graph will extend infinitely in both directions. Therefore, the domain of the graph is all real numbers.

We can't write this as an inequality, but we can write:

[tex]x\in\mathbb{R}[/tex]

For the range, we can see from the graph that the lowest y-value is y=-5. The graph doesn't go any lower than that. However, the graph will also cover all values greater than -5. Therefore, the range of the graph is all values greater than or equal to -5. In an inequality, this is:

[tex]y\geq -5[/tex]

Answer:

the answer is 80

Step-by-step explanation:

Answer:

Step-by-step explanation:

s + at = F

at = F - s

t = (F - s)/a

x/a + y/b = 1

x/a = 1 - y/b

a(x/a = 1 - y/b)

x = a - ay/b

Answer:

C

Step-by-step explanation:

the statement (y<1/2x -4) reads "y is LESS than 1/2 x -4."

to fulfil this statement, follow these steps.

1) graph the line 1/2x -4, there will be a yintercept at (0,-4). Also the slope will be increasing (left to right) because 1/2 has no negative sign before it.

2) recognize the inequality sign. In this situation, the solution does NOT INCLUDE THE LINE, rather it includes the area BELOW/LESS THAN the line. If this, < had a line under it, it would mean less than OR equal to.

3) know that if the line is not included, the line will be broken. If the line IS included, which it is not, it would be a solid line.

Answer:

C

Step-by-step explanation:

First, graph the equation:

The y-intercept is -4.

And the slope is 1/2, an upward sloping line.

So, our graph should be either A, B, or C.

D is not correct, so eliminate that.

So, our inequality is:

[tex]y<\frac{1}{2}x-4[/tex]

Note that this inequality is strictly less than. There's no "or equal to" bar. Therefore, our line should be dotted.

Thus, eliminate A and B.

So, C is our answer

Further notes:

The inequality sign means that y is less than the equation. In other words, our shaded region should be below the line.

In C, the shaded area is indeed below the line.

So, C is indeed our answer :)

Answer:

H = 8 + 3t

Step-by-step explanation:

H = height

t = time in months

H = 8 + 3t

H is the height at and given time. 8 is the initial height and since it grows 3 in a month it would be 3 times how ever many months have passed.

For example after 6 months

t = 6

H = 8 + 3 (6)

H = 8 + 18

H = 26in

3 of the 6 sides that exist on a dice have odd numbers.

Answer:

Step-by-step explanation:

Dice have the given outcomes of getting a 1, 2, 3, 4, 5, or 6. Considering that the desired outcomes are only 3 out of 6 of those given outcomes, that leaves us with a 3/6 or 1/2 chance of getting an odd number.
