All you have to do is make a equation. Which would be p5+3 =v  the answer should be 8 because if you plug 8 in you get (8)5+3=v  40+3= 43 then you add 8 to 43 and get 51 so i believe the answer to your question is 8

Answer: There are 8 pepperoni pizzas she order.

Step-by-step explanation:

Since we have given that

Number of vegetable pizzas and pepperoni pizzas for the eighth grade party = 51

Let the number of pepperoni pizzas be 'p'.

Let the number of vegetable pizzas be 'v'.

According to question,

v=5p+3

So, it becomes,

v+p=51\\\\5p+3+p=51\\\\6p+3=51\\\\6p=51-3\\\\6p=48\\\\p=\dfrac{48}{6}\\\\p=8

Hence, there are 8 pepperoni pizzas she order.

Use the multiplication property of equality to multiply both sides of the equation by 1/6 to get: (1/6)6x=(1/6)48.

X= 8 because by multiplying the fraction with a whole number you had to to convert it to i a fraction and that equals one and then 1/6 times 48 is 8

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = -8x

4x - y = 3

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em>:                    4x - (-8x) = 3
  2. Simplify:                               4x + 8x = 3
  3. Combine like terms:           12x = 3
  4. Isolate <em>x</em>:                              x = 3/12
  5. Simplify:                               x = 1/4

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                    y = -8x
  2. Substitute in <em>x</em>:                       y = -8(1/4)
  3. Multiply:                                  y = -2

A car and a truck left Washington, DC traveling in opposite directions. The car traveled 19 miles per hour faster than the truck
sertanlavr [38]
Truck speed be x
car travel at x+19
they travel in opposite directions
so the separation is (x+x+19) * no. of hours
1048 = (2x+19)*8
x = ((1048/8) - 19)/2
=56

truck speed is 56 miles per hour
car speed is 56+19 = 75 miles per hour
