Value of P: 3/15(p+10)=-15
ArbitrLikvidat [17]
<span>Step  1  :</span> 1 Simplify — 5 <span>Equation at the end of step  1  :</span> 1 (— • (p + 10)) - -15 = 0 5 <span>Step  2  :</span><span>Equation at the end of step  2  :</span> (p + 10) ———————— - -15 = 0 5 <span>Step  3  :</span>Rewriting the whole as an Equivalent Fraction :

<span> 3.1 </span>  Subtracting a whole from a fraction 

Rewrite the whole as a fraction using <span> 5 </span> as the denominator :

-15 -15 • 5 -15 = ——— = ——————— 1 5

<span>Equivalent fraction : </span>The fraction thus generated looks different but has the same value as the whole 

<span>Common denominator : </span>The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

<span> 3.2 </span>      Adding up the two equivalent fractions 
Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(p+10) - (-15 • 5) p + 85 —————————————————— = —————— 5 5 <span>Equation at the end of step  3  :</span> p + 85 —————— = 0 5 <span>Step  4  :</span>When a fraction equals zero :<span><span> 4.1 </span>   When a fraction equals zero ...</span>

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the <span>denominator, </span>Tiger multiplys both sides of the equation by the denominator.

Here's how:

p+85 ———— • 5 = 0 • 5 5

Now, on the left hand side, the <span> 5 </span> cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :
   p+85  = 0

Solving a Single Variable Equation :

<span> 4.2 </span>     Solve  :    p+85 = 0<span> 

 </span>Subtract  85  from both sides of the equation :<span> 
 </span>                     p = -85 

One solution was found :                  <span> p = -85</span>

2. Which product is negative?
Paul [167]

Answer:

B) , C)

Step-by-step explanation:

Assuming that you are multiplying each of the numbers for each given answer.

Look at the amount of negative signs provided. Odd amounts of negative will always guarantee a product of a negative answer. Even amounts of negative will always guarantee a product of a positive answer.

In this case, C. -4 , -4 , -4 , 4 & B. -4 , -4, -4, 4 are your answers, for both only have 3 negative signs, which would make a negative answer.

A line intersects the point (6,9) and (7,4). What is the slope intercept equation for this line?
taurus [48]

Answer:

y = -5x + 39

Step-by-step explanation:

Plug either ordered pair into the Point-Slope Formula FIRST, <em>y</em><em> </em><em>-</em><em> </em><em>y</em><em>₁</em><em> </em><em>=</em><em> </em><em>m</em><em>(</em><em>x</em><em> </em><em>-</em><em> </em><em>x</em><em>₁</em><em>)</em><em>,</em><em> </em>then convert to Slope-Intercept Form by moving whichever term is nearest to <em>y</em><em>,</em><em> </em>over to the right side of the equivalence symbol to get the above answer.

2c +3 = 3c - 4<br> Help me please
VashaNatasha [74]

Hey there!

<u>Solve </u><u>the </u><u>equation</u><u>:</u>

  • Answer :

c = 7 ✅

  • Explanation

2c + 3 = 3c - 4

<em>></em><em>></em><em> </em><em>Subtract </em><em>3</em><em> </em><em>from </em><em>both </em><em>sides </em><em>:</em>

<em> </em>

2c + 3 - 3 = 3c - 4 - 3

2c = 3c - 7

<em>></em><em>></em><em> </em><em>Substrat </em><em>3</em><em>c</em><em> </em><em>from </em><em>both </em><em>sides </em><em>:</em>

2c - 3c = 3c - 7 - 3c

-c = -7

<em>></em><em>></em><em> </em><em>Divide</em><em> </em><em>each </em><em>side </em><em>by </em><em>-</em><em>1</em><em> </em><em>:</em>

-c / -1 = -7 / -1

c = 7

  • Let's verify:

2c + 3 ⇔ 2(7) + 3 ⇔ 14 + 3 ⇔ 17

3c - 4 ⇔ 3(7) - 4 ⇔ 21 - 4 ⇔ 17

Therefore, your answer is c = 7 .
