7(1 - y) = -3(y - 2)

Answer:

12

Step-by-step explanation

so what I did is I divided 15 by 5 to get 3 also 9 divided by 3 equals 3 to so you could of also done that.

then i multiplied to 4 x 3 to get the missing side length which equals 12

Answer:

the answer is 12

Step-by-step explanation:

to find the length we us this formula a²+b²=c²

a²+b²=c²

a²+(9)²=(15)²

a²+81=225

a²=225-81

a²=144

a=√144

a= 12 unit

10x + 8y - 2

Step-by-step explanation:

[tex]-2(-5x – 4y+1) \\ \\ = ( - 2)( - 5x) - 2 ( - 4y) - 2 \times 1 \\ \\ = 10x + 8y - 2[/tex]

Answer:

True

Step-by-step explanation:

This equation correctly represents the total cost of the food that the friends ended up paying for the popcorn and sodas. In this expression, the cost of each individual soda is represented by the variable x which is multiplied by 4 since each one of the four friend's purchased their own soda. After making this multiplication process that product is added to the initial $12 that they all spent together on the popcorn.

Each friend paid $4 for popcorn.

The total cost of the food can be represented by the expression 4x + $12.

Given

Four friends bought an extra-large $12 popcorn.

Each person bought their own drink.

Let x be the number of friends.

The total cost of food= Total number of friends + cost of popcorn.

The total cost of the food can be represented by the expression 4x + $12.

Therefore;

The amount paid by each friend is;

[tex]\rm 4x=12\\\\x=\dfrac{12}{3}\\\\x=4[/tex]

Hence, each friend paid $4 for popcorn.

Answer:

27 isn't a prime because of the fact that it can be divided by 27.

And for your information, Prime numbers are numbers that can't be divided by any number other than 1 and itself.

Every triangle has a total of 180 (when you add all three angles together), and the same would be for a straight angle, or two angles formed by am angle bisector (DC). 180-33=147, so the top part of C would be 147, which isn't necessarily needed, but that'd be how to solve that. A+B+C=180. A+2x+C=180. A would be 33 because AB and DC (segments) are parallel, and the segment bisector AE is a straight line, so 33+2x+C=180. 180-33=147/2=73.5, if I did that correctly.

Step-by-step explanation:

Answer:

(1, -3) is a solution to the system of equations ⇒ B

Step-by-step explanation:

Let us solve the system of equations

∵ 3x + 2y = -3 ⇒ (1)

∵ 3x - y = 6 ⇒ (2)

→ Subtract equation (2) from equation (1)

∵ (3x - 3x) + (2y - -y) = (-3 - 6)

∴ (0) + (2y + y) = (-9)

∴ 3y = -9

→ Divide both sides by 3 to find y

∴ y = -3

→ Substitute the value of y in equation (2) to find x

∵ 3x - (-3) = 6

∴ 3x + 3 = 6

→ Subtract 3 from both sides

∵ 3x + 3 - 3 = 6 - 3

∴ 3x = 3

→ Divide both sides by 3 to find x

∴ x = 1

To check the answer substitute the values of x any in each equation if the two sides of the equation are equal, then the solution is right

∵ 3x + 2y = -3

∵ 3(1) + 2(-3) = -3

∴ 3 - 6 = -3

∴ -3 = -3

→ The two sides of the equation are equal

∵ 3x - y = 6

∵ 3(1) - (-3) = 6

∴ 3 + 3 = 6

∴ 6 = 6

→ The two sides of the equation are equal

∴ The solution satisfies the two equations

∴ (1, -3) is a solution to the system

Answer:

Your answer should be 15.

Step-by-step explanation:

3 times 9 is 27. When you subtract a negative number they combine to sign to be a + so you would get 30 since you would be adding 3. You would then divide 30 by two to get 15! <3

Answer:

B. [tex] y = 160x + 2400 [/tex]

Step-by-step explanation:

The linear equation for that represents the above data is given in slope-intercept form as [tex] y = mx + b [/tex], where:

m = slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]

b = starting value = y-intercept = 2,400

Slope of the linear equation using (0, 2400) and (10, 4000):

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4000 - 2400}{10 - 0} = \frac{1600}{10} = 160 [/tex]

Substitute m = 160, and b = 2,400 in [tex] y = mx + b [/tex].

Thus, the linear equation in slope-intercept form would be:

✅[tex] y = 160x + 2400 [/tex]

A. a two-column proof consist of a list of statements and the reasons the statements are true.

B. a flowchart proof gives a visual representation of the sequence of steps without justification.

D. a two-column proof list only the given information and what is to be proven.

Step-by-step explanation: This is the correct answer on Edge 2021, just took the quiz. Hope this helps. ^-^

The correct statements are:

In a paragraph proof, statements and their justifications are written in sentences in a logical order.

A two-column proof consists of a list of statements and the reasons the statements are true.

A flowchart proof is a visual way of describing the statements and reasons for a proof.

A flowchart is a graphical representation of a process, algorithm, or system that uses symbols, shapes, and arrows to depict the various steps and their interconnections.

We have,

In a two-column proof, each statement is listed in one column, and the justification for the statement is listed in a separate column.

A flowchart proof also provides a visual representation of the sequence of steps, but it includes justifications for each step.

So,

The following statements are incorrect:

A flowchart proof gives a visual representation of the sequence of steps without justifications.

A two-column proof lists only the given information and what is to be proven.

Thus,

The correct statements are:

In a paragraph proof, statements and their justifications are written in sentences in a logical order.

A two-column proof consists of a list of statements and the reasons the statements are true.

A flowchart proof is a visual way of describing the statements and reasons for a proof.
