Solve the given equation.
- 29 = - 13 - n
Write step by step how you solved it.

Answers

Answer:

The answer is n=16

Step-by-step explanation:

Let's solve your equation step-by-step.

−29=−13−n

Step 1: Simplify both sides of the equation.

−29=−13−n

−29=−13+−n

−29=−n−13

Step 2: Flip the equation.

−n−13=−29

Step 3: Add 13 to both sides.

−n−13+13=−29+13

−n=−16

Step 4: Divide both sides by -1.

−n/−1 =−16/−1

n=16

Triangles PQR and STU are similar. The length of PQ = 36 cm, RP = 48 cm and QR = 24
cm. THe length of the longest side of triangle STU is 92 cm. What is the perimeter of
triangle STU?

Answers

Answer:

207 cm

Step-by-step explanation:

Because ΔPQR ≅ΔSTU and the longest side in the ΔPQR is RP then the longest side in ΔSTU must be SU = 92 cm

Perimeter of triangle PQR is

P(ΔPQR) = 36+48+24 = 108 cm

Because the triangles are are similar their sides are in proportion.

But how much bigger did the second triangle get?...is (92/48) times bigger

P(ΔSTU) = 180*(92/48) = 207 cm

...you can also use proportions to find each side and then find the perimeter

TU = 24*92 /48 = 46

TS = 36*92/48 = 69

SU = 92

P(ΔSTU) = 92+69+46 =207 cm

Anna is counting the number of seeds in her fruit. Her watermelon has one less than three times the number of seeds as her apple. Her orange has 13 less than 5 times the number of seeds as her apple. Her watermelon has more seeds than her orange. Which inequality represents the number of seeds her apple could have?

Answers

Inequalities are used to represent unequal expressions

The inequality that represents the number  of  seeds her apple could  have is [tex]\mathbf{A < 6}[/tex]

Represent the fruits with the first letter.

So, we have:

[tex]\mathbf{W =3A - 1}[/tex] --- watermelon is one less than three times apple

[tex]\mathbf{O =5A - 13}[/tex] --- orange is thirteen less than five times apple

[tex]\mathbf{W > O}[/tex] --- the seeds in watermelon exceeds orange

Substitute expressions for W and O in [tex]\mathbf{W > O}[/tex]

[tex]\mathbf{3A - 1 > 5A - 13}[/tex]

Collect like terms

[tex]\mathbf{13- 1 > 5A - 3A}[/tex]

[tex]\mathbf{12 > 2A}[/tex]

Divide both sides by 2

[tex]\mathbf{6 > A}[/tex]

Rewrite as:

[tex]\mathbf{A < 6}[/tex]

The inequality that represents the number  of  seeds her apple could  have is [tex]\mathbf{A < 6}[/tex]

Step-by-step explanation:

mark as a brainlist

Answer:

8 : 24 = 1 : 3

Step-by-step explanation:

The ratio is not in lowest terms so we found an equivalent ratio by simplifying

We can simplify the ratio 8 : 24 by dividing both terms by the greatest common factor (GCF).

The GCF of 8 and 24 is 8.

Divide both terms by 8.

8 ÷ 8 = 1

24 ÷ 8 = 3

Therefore:

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equation is (3j+k)/2=15-4k

We need to prove j=10-3k

(3j+k)/2=15-4k

Apply cross multiplication and solve for k

3j+k=2(15-4k)

3j+k=30-8k

Subtract k from both sides

3j=30-9k

C.Associative Property of Addition
D.Associative Property of Multiplication

Answers

The answer is D. Associative Property of Multiplication.

(7a*2b)+3c=3c+(7a*2b) the property for the given expression is Option A) Commutative Property of Addition.

The given expression is (7a*2b) + 3c = 3c + (7a*2b). This equation demonstrates the Commutative Property of Addition.

The Commutative Property of Addition states that the order in which numbers are added does not affect the result.

In mathematical terms, it can be written as: a + b = b + a.

In your expression, you have terms involving both addition and multiplication. However, since addition is involved on both sides of the equation, we can focus on the addition aspect.

(7a*2b) + 3c = 3c + (7a*2b)

First, we can rearrange the terms on the left side:

7a*2b + 3c = 3c + 7a*2b

Now, observe that the terms on both sides of the equation are the same: 7a*2b and 3c.

They are just arranged in a different order. This aligns with the Commutative Property of Addition, which says the order of addition doesn't matter.

Therefore, the expression is an illustration of this property, and the correct answer is the Commutative Property of Addition (A).

In summary, the expression shows that changing the order of terms within an addition does not change the result, thus demonstrating the Commutative Property of Addition.

Answer:

y = 2/3x - 5  or   in standard form 3y = 2x - 5

Step-by-step explanation:

Remember this fact: Parallel lines have the same slope

Step 1   Solve for y  so that the equation is in the slope- intersect form

         2x - 3y = 6

          -3y = -2x + 6  

           -3y/-3  = -2x/-3 + 6/-3

             y = 2/3 x -2        

  now we know the slope is 2/3  or

   when the equation is in Standard form Ax + By = C   you can use this fact:  slope = - A/B    so  the slope = -2/-3 = 2/3

    Remember the   Parallel lines have the same slope

     Find the y-intersect "b"     use the slope = 2/3 and point (6, -1)

      y = mx + b

       -1 = 2/3(6) + b

       -1 = 4 + b

       -5 = b    

Now write the equation of line that is parallel to the given line and passes through  point (6, -1)

y = 2/3x - 5  or  in standard form 3y = 2x - 5

Which equation has only one unique solution?

A.
|3 − x| = 3
B.
|x − 2| − 7 = 7
C.
-4|x| + 1 = -3
D.
9 − |2x − 1| = 9

Answers

The equation with only one unique solution is 9 − |2x − 1| = 9, with the solution x = 1/2. D.

To determine which equation has only one unique solution, let's analyze each equation:

|3 − x| = 3

In this equation, the absolute value term represents a distance.

By setting up two cases, where the absolute value is positive and negative, we can find the solutions.

Case 1:

3 - x = 3

Solving for x, we have x = 0.

Case 2:

x - 3 = 3

Solving for x, we have x = 6.

Thus, this equation has two solutions.

|x − 2| − 7 = 7

Similar to equation A, the absolute value term represents a distance.

By adding 7 to both sides, we have |x - 2| = 14.

This equation implies that the distance between x and 2 is 14.

There are two possible values for x: x = 2 + 14 = 16 and x = 2 - 14 = -12.

This equation has two solutions.

-4|x| + 1 = -3

To solve this equation, we isolate the absolute value term:

-4|x| = -4

Dividing both sides by -4:

|x| = 1

The absolute value of any number is always positive or zero.

The equation |x| = 1 has two solutions: x = 1 and x = -1.

9 − |2x − 1| = 9

The absolute value term represents a distance.

Subtracting 9 from both sides, we have |2x - 1| = 0.

The only way the absolute value of a real number can be equal to zero is if the number inside the absolute value is zero.

Thus, we set 2x - 1 = 0 and solve for x:

2x - 1 = 0

2x = 1

x = 1/2

Equation D has only one unique solution: x = 1/2.
