Is -4(5x)=12 true false or open

Answer:

(3/5, 1/5)

General Formulas and Concepts:

Pre-Algebra

Algebra I

Step-by-step explanation:

Step 1: Define systems

3x + y = 2

4x + 3y = 3

Step 2: Rewrite systems

y = 2 - 3x

4x + 3y = 3

Step 3: Solve for x

Step 4: Solve for y

Step 5: Check

Graph the systems of equations.

Answer:

x = 3/5, y = 1/5

Step-by-step explanation:

Starting with:

3x + y = 2

4x + 3y = 3

Multiplying the first equation by -3:

-9x - 3y = -6

4x + 3y = 3

Adding the equations:

-5x = -3

Simplifying:

x = 3/5

Substituting x = 3/5 into the first equation:

9/5 + y = 2

Subtracting:

y = 1/5

Answer:

x = 18

Step-by-step explanation:

The product of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord, that is

21x = 14 × 27 = 378 ( divide both sides by 21 )

x = 18

Answer:

66

Step-by-step explanation:

because if you ad 60 and 6 it makes yes

Answer:x = 3

because (34x - 2) and (32x + 4) are two opposite angles

=> 34x - 2 = 32x + 4

⇔ 34x - 32x = 4 + 2

⇔ 2x = 6

⇔ x = 3

Answer:

{x+y=36

0.1x+0.25y=5.4

Step-by-step explanation:

just took the test sorry for being late

The system of equation that is used to find how many dimes and quarters Victor has is :

x + y = 36

0.1x + 0.25y = 5.40

x = number of dimes

y = number of quarters

Therefore,

Total number of coins will be

1 dime = $0.1

1 quarters =$0.25

Therefore,

Total amount of dollars will be

combine the equations:

x + y = 36

0.1x + 0.25y = 5.40

Therefore, the system of equation that is used to find how many dimes and quarters Victor has is as follows:

x + y = 36

0.1x + 0.25y = 5.40

Answer:

There is 2145.52 cubic inches of air in the ball

Step-by-step explanation:

A round ball is an example is hollow sphere. In order to find how much air the ball holds, the volume of the sphere needs to be found.

Given

Radius = r = 8 in

The volume of sphere is given by:

[tex]V = \frac{4}{3} \pi r^3[/tex]

Putting the values we get

[tex]V = \frac{4}{3} * \frac{22}{7} * (8)^3\\V = \frac{4}{3} * \frac{22}{7} * 512\\V = \frac{45056}{21}\\V = 2145.52\ in^3[/tex]

Hence,

There is 2145.52 cubic inches of air in the ball

Answer:

y = 2x -1

Step-by-step explanation:

when a two lines are parallel to each other that means they have the same slope.

you use point slope formula to find a line with the same slope and passes through (2,3)

y - y' = m(x - x') is the general form so you plug in (2,3) and the slope and you get

y - 3 = 2(x -2)

first your distribute the 2 into the parenthesis and you get

y-3 = 2x -4

now add 3 to both sides

y = 2x -1

Answer:

[tex]Number = 11\frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]Soup = 7\frac{1}{2}[/tex] quarts

[tex]Portion = \frac{2}{3}[/tex] quarts

Required

Determine the number of portions in the soup

The question illustrates division of fractions and to solve this question, we simply divide the size of the soup by the size of the given portion

[tex]Number = Soup/Portion[/tex]

Substitute values for Soup and Portion

[tex]Number = 7\frac{1}{2}\ quarts /\frac{2}{3} \ quarts[/tex]

[tex]Number = 7\frac{1}{2}/\frac{2}{3}[/tex]

Convert mixed fraction to improper fraction

[tex]Number = \frac{15}{2}/\frac{2}{3}[/tex]

[tex]Number = \frac{15}{2} * \frac{3}{2}[/tex]

[tex]Number = \frac{15*3}{2*2}[/tex]

[tex]Number = \frac{45}{4}[/tex]

[tex]Number = 11\frac{1}{4}[/tex]

Hence, there are [tex]11\frac{1}{4}[/tex]  of [tex]\frac{2}{3}[/tex] quarts in [tex]7\frac{1}{2}[/tex] quarts of soup

Answer: It should be division property of equality.

Answer:

Division Property of Equality

Step-by-step explanation:

To solve this problem Remus needs to isolate the variable, which means to get rid of the 7. Since the 7 is being multiplied the opposite operation needs to be used; the opposite of multiplication is division. So each side needs to be divided by 7, the division property of equality tells us that an equation can be divided by anything as long as it is done on both sides. So to solve use the division property of equality to do 7q/7=49/7, which equals q=7 when simplified.

∠ PRQ = 55°

Step-by-step explanation:

The angle subtended at the centre by an arc is twice the angle subtended at the circumference by the same arc, thus

∠ PQR = 0.5 × 110° = 55°

Answer: AC = 7√3

tan 30° = [tex]\frac{BC}{AC}[/tex]

=> [tex]\frac{BC}{AC}=\frac{1}{\sqrt{3} }\\\\\=> AC=BC\sqrt{3} =7\sqrt{3}[/tex]

He will cover 2,827.433 feet² area of the park with plant food.

Step-by-step explanation:

The diameter of the garden is 60 feet and the radius will be 60 feet/2 = 30 feet.

diameter= 60 feet

radius = diameter/ 2= 60/2= 30 feet

The area of the circle can be found by the formula πr²

Area= πr²=π(30)²

 Area = 900π= 2,827.433 feet²

He will cover 2,827.433 feet² area of the park with plant food.
