how to cancel 10+5/12*9l​

k=-3

6*(-4k)=18

subtract 6 from both sides

-4k=12

divide by -4 on both sides

k=-3

Answer:

[tex] \sf \: k = - 3[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of k.

The equation is,

→ 6 + (-4k) = 18

Then the value of k will be,

→ 6 + (-4k) = 18

→ 6 - 4k = 18

→ -4k = 18 - 6

→ -4k = 12

→ k = 12 ÷ (-4)

→ [ k = -3 ]

Hence, the value of k is -3.

Answer is 33,385

I multiply 12244 and 5 which gave me 11220. Then I multiply 4433 and 5 which gave me 22165. Lastly you add 11220 and 22165 which you answer is 33,385

25° is the correct answer.

Step-by-step explanation:

(4x+20) +60°=180° [°.° Linear Pairs]

[tex](4x + 20) + 60° = 180°\\ ⟹ 4x + 20 + 60° = 180° \\ ⟹ 4x + 80° = 180° \\ ⟹ 4x = 180° - 80° \\ ⟹x = \frac{100°}{4} \\ ⟹25°[/tex]

Infinite solutions because the equation is true but it doesn't tell anyone what number it equals to and it says the x equals to itself.

Answer:

18x + 24

Step-by-step explanation:

Given

6(3x + 4) ← distribute by multiplying each term in the parenthesis by 6

= 18x + 24

Answer:

You use substitution

Step-by-step explanation:

Because you can see that y= both of those answers, you can set them equal to each other, creating the equation 2=x^2-3x-8

You then can use quadratics to solve the equation as follows:

-2 from both sides, 0=x^2-3x-10

Factors of -10 that add up to -3 are -5 and 2 leaving

0=(x-5)(x+2)

The 0 product property tells us that the answer is 5 and -2

Answer:

0.01

Step-by-step explanation:

When rounding to the nearest hundredth, you look in the thousandths place to see if the number is 5 or greater. In this case it is. The hundredths place then moves up one number.

=0.01

Answer:

-5 is an integer.

Step-by-step explanation:

Answer:

it is an integer

Step-by-step explanation:

It's and integer because a whole number goes up higher but never pass 0

an integer has whole numbers and their negative counterparts it would be a whole if it was just 5 and not -5 and it would be rational if it were -5.5

Answer:

Each side is 4 cm.

Step-by-step explanation:

We need to try to express the perimeter of the figure in terms of "square sides". Basically, we're going to count how many square sides the perimeter is.

Starting from the top, the very top is 1 side.

Moving down to the right, we have another side.

Then half a side as we go to the right edge.

The right edge is 1 full side.

Another half side, going left.

Going down, we have 1 full side.

The other side is mirrored, meaning we just have to double this to get the full figure's perimiter.

Counting up our sides (we'll call one side [tex]s[/tex] ), we have:

1s + 1s + 0.5s + 1s + 0.5s + 1s = 4s + 0.5s + 0.5s = 5s

Doubling it:

5s * 2 = 10s

The whole perimiter is 8 square sides. Since we know the perimeter is 40 cm, we can find the length of one side by solving this equation:

10s = 40

Dividing both sides by 10:

s = 40/10 = 4

Answer: Each side is 4 cm.

Answer:

Perimeter = 28.84 m

Step-by-step explanation:

Since the other two points will make the shape to look like a square, each length of the square will be equal.

We can therefore find the length PQ by using the formula

L = sqrt ( [ X2 - X1 ]^2 + [ Y2 - Y1 ]^2

L = sqrt( [ -2 + 4 ]^2 + [ 4 + 3]^2

L = sqrt (4 + 49)

L = sqrt (52)

L = 7.2 m

Each length of the square is 7.2 m approximately

The parimeters will be:

Perimeter = 4L

Perimeter = 4 × 7.2

Perimeter = 28.84 metres

Therefore, the perimeter of the square is 28.84

Answer:

the answer for x<5

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

−4<−4x+16

Step 2: Flip the equation.

−4x+16>−4

Step 3: Subtract 16 from both sides.

−4x+16−16>−4−16

−4x>−20

Step 4: Divide both sides by -4.

Answer:

C

Step-by-step explanation:

Both the given equations are of Perpendicular lines.

Perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).

Given are two equations of lines

y-2= x+20

y = x+20+2

y = x+22.....(i)

y-2= -(x+20)

y = -x-20+2

y = -x-18,,,,,,,(ii)

The slopes of the equation are 1 and -1, We know that perpendicular lines have slopes that are negative reciprocals of one another.

Hence, The lines given are perpendicular lines

Answer:

15

Step-by-step explanation:

====================================================

Explanation:

Divide by the smallest prime 2

90/2 = 45

Then divide by the next smallest prime 3 (since 2 won't go into 45)

45/3 = 15

Repeat the last step

15/3 = 5

We stop because the result is prime.

Note the denominators are 2, 3, 3. The final result is 5 which is prime.

So the prime factors are 2, 3, 3,  and 5

They multiply to 2*3*3*5 = 90.

We can condense it to 2*3^2*5 = 90 because 3*3 = 3^2.

Answer and Step-by-step explanation:

The prime factorization of 90 is 2 × 3 × 3 × 5 or 2 × 32 × 5, where 2, 3, and 5 are the prime numbers. You can find "prime factorization" by following two simple steps. Step 1: Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Step 2: Write the number as a product of prime numbers.
