1.80 x 5= 2.16
b
1.80 ÷ 5= 2.16
c
1.80 ÷ 2= 0.90
d
1.80 ÷ 5= 0.36

Answer:

It means (x+2) is a factor and x = -2 is a root.

Step-by-step explanation:

I know this bc i took the test and got it right

[tex]a(c - b) = d[/tex]

Divided sides by a

[tex] \frac{a}{a}(c - b) = \frac{d}{a} \\ [/tex]

[tex]c - b = \frac{d}{a} \\ [/tex]

Plus sides b

[tex]c - b + b = \frac{d}{a} + b \\ [/tex]

[tex]c = \frac{d}{a} + b \\ [/tex]

Done.....♥️♥️♥️♥️♥️

Answer:

[tex]c = \frac{ab + d}{a}[/tex]

Step-by-step explanation:

Step 1: Add ab to both sides.

−ab + ac + ab = d + ab

ac = ab + d

Step 2: Divide both sides by a.

[tex]\frac{ac}{a} =\frac{ab + d}{a}[/tex]

[tex]c = \frac{ab + d}{a}[/tex]

Answer:

B.

Step-by-step explanation:

Answer:

[tex]\angle 1=39\textdegree[/tex]

Step-by-step explanation:

Remember that the sum of the interior angles of a triangle always equal 180. Therefore:

[tex]\angle 1+\angle Y+102=180[/tex]

Let's subtract 102 from both sides. This yields:

[tex]\angle 1+\angle Y=78[/tex]

Now, notice the that both ∠1 and ∠Y have exactly one arc mark.

Arc-marks denote congruence. Therefore, ∠1 and ∠Y are congruent to each other. In other words:

[tex]\angle 1=\angle Y[/tex]

So, we can substitute ∠Y for ∠1 for our equation. This yields:

[tex]\angle 1+\angle 1=78[/tex]

Combine like terms:

[tex]2\angle 1=78[/tex]

Divide both sides by 2. So, the measure of our angle is:

[tex]\angle 1=39\textdegree[/tex]

And we're done!

Answer:

Step-by-step explanation:

given the total amount at hand is $25

let the price of  candy be x

then the cost of 3 candy will  be 3x

the cost of a candy snake is $12.50.

balance at hand after the end of buying $8.75

the total expenses summed up must equal the initial amount at hand which is $25

the expression for the scenario is 3x+12.5+8.75=25

3x+21.25=25

3x=25-21.25

3x=3.75

x=3.75/3

x=$1.25

The cost of a candy is $1.25

Answer:

x = 25

Step-by-step explanation:

3x + 5 + 5x - 25 = 180 (collect like terms)

8x - 20 = 180 (add 20 on both sides)

8x = 200 (divide by 8 on both sides)

x = 25

Since they are supplementary that mean together they add up to 180 so that's why I added them together.

Answer:

A) 3w(w-7)

Step-by-step explanation:

[tex]\frac{w-5}{w-7} and \frac{w+8}{3w}[/tex]

w-7 is a binomial, and 3w is a monomial. Because you cannot put one denominator into the other or multiply both denominators by a number when you have this type of difference where multiplying by a number won't get you the same result, you must multiply them each other.

Therefore:

3w(w-7) would be your LCD.

Answer:

Step-by-step explanation:

Fractions

We observe that the fractions can't be simplified any more and they are in the simplest form

Next, the denominators w - 7 and 3w don't have common factors

Therefore the common denominator is the product of denominators:

Answer:

7 degrees

Step-by-step explanation:

The temperature in Monday was 14 degrees

On tuesday the temperature decreased by 5 degrees

On Wednesday it decreased by 10 degrees

On thursday the temperature increased by 8 degrees

Therefore the temperature at the end of the day on Thursday can be calculated as follows

= 14 - 5 - 10 + 8

= 7

Hence the temperature at the end of the day on Thursday is 7 degrees

1kg = 2.2lb

1lb = 0.454kg

132lb = 0.454*132

132lb = approx 60kg

Given parameters:

Mark up percentage  = 150%

Original cost = $488

Sales tax = 5%

Unknown:

His total cost  = ?

Solution:

Marking up a good is the amount a sell adds to a product which makes its selling price usually for a profit.

 Since the emerald was marked up by 150%;

   New cost  = (1 + 1.5) x $488 = $1220

Now, the additional tax was 5%;

   Tax = [tex]\frac{5}{100}[/tex] x 1220 = $61

So, the total cost = New cost + tax  = $1220 + $61 = $1281

Step-by-step explanation:

Two- fifths

Answer:

The answer is 2/5 (B)

Step-by-step explanation:

1/3 divided by 5/6

To solve, we need to multiply the reciprocal of the divisor (5/6 in this case)

The reciprocal of 5/6 is 6/5

1/3*6/5 = 6/15 which can be reduced to 2/5

The answer is 2/5 (B)

Answer:

y = -4x - 6

Step-by-step explanation:

12x + 3y = -18

Solve for y.

3y = -12x - 18

y = -12/3 x - 18/3

y = -4x - 6

Answer:

Step-by-step explanation:

<a = 85° ( Vertically Opposite Angles )

<b = 180 - 85 = 95° ( Adjacent Angles )

Hope this helps

Plz mark as brainliest!!!!!!!!

Answer:

<a=85

<b=95

Step-by-step explanation:

<a is going to be the same as the other angle is across from it. So <a equals 85 degrees. So now since we know that two parts are 85 degrees we add 85 + 85 and we get 170 degrees. Since the whole thing is 360 degrees we need to subtract the 170 degrees that we already have. So 360-170 is equal to 190 degrees. Now since <b is the same as the angle across from it is we just need to divide the remaining degrees in half. So we take the 190 degrees and divide that in half. When you divide that in half you get 95 degrees. So <b is 95 degrees.

[tex]4 - 2(x - 3) = 24 \\ [/tex]

[tex]⇒4 - 2x + 6 = 24 [/tex]

[tex]⇒ - 2x = 24 - 6 - 4[/tex]

[tex]⇒ - 2x = 14[/tex]

[tex]⇒x = \frac{14}{ - 2} [/tex]

[tex]⇒x = - 7[/tex]

Hence, Answer is -7.

Answer:

- 7

Step-by-step explanation:

Step 1:

4 - 2 ( x - 3 ) = 24      Equation

Step 2:

4 - 2x + 6 = 24           Multiply

Step 3:

- 2x + 10 = 24       Combine Like Terms

Step 4:

- 2x = 14           Subtract 10 on both sides

Step 5:

x = 14 ÷ - 2       Divide

Answer:

x = - 7
