Answer: p=8

Step-by-step explanation:

4p-11=21

We move all terms to the left:

4p-11-(21)=0

We add all the numbers together, and all the variables

4p-32=0

We move all terms containing p to the left, all other terms to the right

4p=32

p=32/4

p=8

Answer:

p=-8

Step-by-step explanation:

21=-4p-11

1) Add 11 to both sides:

32=-4p

2) Divide both sides by -4 to isolate p:

p=-8

Which expression is equal to (6x−4)(3x−1)?

Natali5045456 [20]

Answer:

$(6x-4)(3x-1) = 18x^2 - 18x + 4$ is the required simplification.

Step-by-step explanation:

Here, the given expression is (6x−4)(3x−1).

By DISTRIBUTIVE PROPERTY of numbers:

A ( B + C ) = AB + AC

Simplifying the given expression, we get:

$(6x-4)(3x-1) = 6x(3x-1)-4(3x-1)\\= 6x(3x) -1(6x) -4(3x) +4\\=18x^2 - 6x - 12x + 4\\18x^2 - 18x + 4$

or, $(6x-4)(3x-1) = 18x^2 - 18x + 4$

Hence the given expression is simplified.

Can someone help me for this question?

Taya2010 [7]

Answer:

2x + 1y =< 300

x + y =>150 units

y <= 2x

Step-by-step explanation:

Let x and y be the numbers of corndogs and shakes that will be sold.

1. The total cost of making these items is given by the sum of:

(x)(RM2) + (y)(RM1)

A total of RM300 is allocated for the cost of these items, so:

2x + 1y =< 300 [Units are RM)

2. Sales are expected to exceed 150 units, in total. This means:

x + y =>150 units

3. Sales for the shakes is less than 2 times that of the corndogs:

y <= 2x
