Step-by-step explanation:

Im guessing its telling you to solve using substitution ?

Well your lucky, most of the work is already done :D

you know y=x-7 , so just replace y with (x - 7) in the other equation

4x - 7(x-7) = 10

4x - 7x + 49 = 10

-3x = -39

x = 13

Now just plug X in the original equation to fine Y

y = x - 7

y = 13 - 7

y = 6

so the solution would be

(13,6)

Given:

The perimeter of a backyard basketball court with four sides is 90 feet.

Two sides of the court are each 20 feet long.

One side of the court is 25 feet long.

To find:

The missing side length of the basketball court.

Solution:

Let x be the missing side length.

The three given sides of the basketball court  are 20 feet, 20 feet, 25 feet.

We know that the perimeter is the sum of all sides.

[tex]Perimeter=x+20+20+25[/tex]

[tex]Perimeter=x+65[/tex]

The perimeter of a backyard basketball court with four sides is 90 feet.

[tex]x+65=90[/tex]

[tex]x=90-65[/tex]

[tex]x=25[/tex]

Therefore, the missing side length is 25 feet and the correct option is B.

Answer and Step-by-step explanation:

Section the figure into two 3D shapes.

We get both figures to be a rectangular prism.

The Volume of a rectangular prism is length times width times height.

V (of top Rectangular Prism) = 2 × 2 × 4 = 16

V (of bottom Rectangular Prism) = 6 × 4 × 2 = 48

Now, we add those two volumes together to get the volume of the irregular figure.

16 + 48 = 64.

The volume of the irregular figure is 64 [tex]cm^3[/tex]

Answer:

Step-by-step explanation:

This is quite and easy one, but also vague at the same time.

A polygon is a shape with 5 or more sides, so, if she were drawing a pentagon, then the second polygon has to be an octagon. A pentagon has 5 sides, and an octagon has 5 + 3 sides

In the same vein, if she were drawing a hexagon, with 6 sides, the other polygon has to be monsoon, with 6 + 3 sides.

A heptagon also gives us a 7 + 3 polygon, in decagon.

All in all, it depends on the first polygon she's drawing as the question is vague in that aspect.

Answer:

9(11+8)=171    8 is your answer

Step-by-step explanation:

99+72=171

For the expression 99 + 72 = 9 (11 + x) the value of x is 8.

Calculate the answer using a math operator is referred to as a mathematical operation.

Basic mathematical operations are addition, multiplication, subtraction and division.

The given expression is,

99 + 72 = 9 (11 + x)

To find the value of x, simplify the expression by using mathematical operations,

171 = 9 (11 + x)

171 / 9 = 11 + x

19 = 11 + x

19 - 11 = x

8 = x

x = 8

The required value of x is 8.

3.25 times 4 equals 13. So, the plant cost needs to add up to 37. 37 divided by 2.5 is 14.8, or rounded, 15. So she can buy around 15 plants.

x=7, x=8

Answer:

x= -7

Step-by-step explanation:

You need to first add 5 to the -5. Even though the - is a subtraction sign, you can still count it as a subtraction sign. In order to balance it out again, so you add the 5 to the 16. 16+5=21, so the equation would be -3x=21. To get x by itself, you divide by -3. So, -3x/-3 and 21/-3. That gets rid of the -3, and you get a -7 as an answer.

Answer:

219.05 m²

Step-by-step explanation:

Dimension of right angle triangle : 109 m and 190 m

The right angle triangle has a height of 190 m and base length of 109 m

A corner of the base from the pyramid's top is equivalent to the hypotenus of the right angle triangle :

Let :

hypotenus = c ; base = b ; height = a

Hypotenus² = opposite² + adjacent²

c² = a² + b²

c² = 190² + 109²

c² = 36100 + 11881

c² = 47981

c = sqrt(47981)

c = 219.04565

A corner of the base from the pyramid's top is 219.05 m²

Answer:

C) 17.1 square units

Step-by-step explanation:

Use Heron's formula to calculate the area of the triangle:

[tex]Area = \sqrt{s(s-a)(s-b)(s-c)}[/tex]  where  [tex]s=\frac{a+b+c}{2}[/tex] which represents the semi-perimeter of the triangle:

[tex]s=\frac{9.9+6.1+6}{2}=11[/tex]

Therefore:

[tex]Area = \sqrt{11(11-9.9)(11-6.1)(11-6)}\\[/tex]

[tex]Area = \sqrt{11(1.1)(4.9)(5)}\\[/tex]

[tex]Area = \sqrt{296.45}\\[/tex]

[tex]Area = 17.2[/tex]

Therefore, the closest answer choice is C) 17.1 square units

Answer:   x + y=100---equation 1

               y =10+ 2x-----equation 2

                 x=30, y=70

Step-by-step explanation:

Given that

x added to a number y is equal to 100 which means that

x + y=100

and also that

y is also equal to 10 more than the number x doubled which is

y =10+ 2x

we have the linear systems to solve the equations as

x + y=100---1

y =10+ 2x-----2

Solving

Putting the value of y =10+ 2x in equation 1

x +10+ 2x =100

10+3x=100

3x=100-10

x=90/3=30

x=30

y=10 +2x = 10+2x30 =70

Answer:

8.38

Step-by-step explanation:

The underlined number is in the hundredths place, so that means that we're going to round there. That means that you look at the number to its right and if it's lower than 5, it stays the same. However, if it's 5 or higher, you round it up. For example, if the number was 8.386, we would round it to 8.39.
