Find the value of 5x - 4x^2 for x=2

Answer:

E1800.00

Step-by-step explanation:

1584 and x. Change is 12.

x-1584/x=0.12

x-1584=0.12x

x-0.12x=1584

0.88x=1584

x=1584/0.88

x=1800.

simplified answer

Step-by-step evaluation:

-9(-8p + 12) - 6p

-9 x -8p = 72p   -9 x 12 = -108

(72p + -108) - 6p

72p + -108 - 6p

(72p + −6p) + (−108)

66p + −108

Answer:

Given:

Fabric required for each chair = 10 yards

Fabric required for each sofa = 20 yards.

Total available fabric = 300 yards.

The number of sofas must be at least twice the number of chairs.

Profit on each chair = $50

Profit on each sofa = $80.

To find:

The function that represents the manufacturer's profit, P.

Solution:

Let P represents the manufacturer's profit, x represent the number of chairs and y represent the number of sofas.

Profit on 1 chair = $50

Profit on x chairs = $50x

Profit on 1 sofa = $80

Profit on y sofas = $80y

Total profit = Profit on x chairs + Profit on y sofas

[tex]P=50x+80y[/tex]

Therefore, the required profit function is [tex]P=50x+80y[/tex].

Answer:

36 crickets per day

Step-by-step explanation:

Calculation for how many crickets do the lizards eat each day

 Using this formula

Numbers crickets eaten per day=Crickets per week/Numbers of days in a week

Let plug in the formula

Numbers crickets eaten per day=250 crickets per week/7days

Numbers crickets eaten per day=35.7

Numbers crickets eaten per day=36 crickets per day (Approximately)

Therefore the numbers of crickets that the lizards eat each day is 36 crickets per day

Answer:

Step-by-step explanation:

0.04

All the numbers that show 4% as an equivalent fraction, decimal or percent from the listed options are:

Percent counts the number compared to 100.

So, if we have a%, that means for each 100, there are 'a' parts. If we divide each of them with 100, we get:

For each 1, there are a/100 parts.

Thus, 50% = 50/100 = 0.50 (in decimal)

For this case, the percent we have is 4%

That shows that for each 100 items, we have 4 of them. This can be written in fraction as 4/100

Solving this division, we get the result in decimal as 0.04

Thus, all the numbers that show 4% as an equivalent fraction, decimal or percent from the listed options are:

Answer:

x = 68

Step-by-step explanation:

The consecutive angles of a parallelogram are supplementary, sum to 180° , then

69 + 43 + x = 180 , that is

112 + x = 180 ( subtract 112 from both sides )

x = 68

Answer:

B!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The equation x = 3y + 3w - 1 can be written as in terms of x and y by making the subject w is w = (x - 3y + 1)/3 option (B) is correct.

It is defined as the combination of constants and variables with mathematical operators.

The question is incomplete.

The complete question is:

If x = 3 (y + w) -1 what is the value of w in terms of x and y?

We have an expression:

x = 3 (y + w) -1

To find the value of w in terms of x and y.

By using the distributive property:

x = 3y + 3w - 1

By arranging the equation:

3w = x - 3y + 1

Divide by 3 on both the side:

w = (x - 3y + 1)/3

Thus, the equation x = 3y + 3w - 1 can be written as in terms of x and y by making the subject w is w = (x - 3y + 1)/3 option (B) is correct.

Answer:

Step-by-step explanation:

Since both equations equals y, then both equations equal each other.

3x - 1 = 2x + 2

Subtract 2x from both sides

x - 1 = 2

Add 1 to both sides

x = 3

Plug x = 3 into one equation(doesn't matter which)

y = 3x - 1

y = 3(3) - 1

y = 9 - 1

y = 8

Answer:

[tex]x=3[/tex]

[tex]y=8[/tex]

Step-by-step explanation:

From these two equations, we can substitute the first equation into the second equation (or the other way round). This gives us:

[tex]3x-1=2x+2[/tex]

[tex]3x-2x=2+1[/tex] (minus [tex]2x[/tex] and add [tex]1[/tex] on both sides)

[tex]x=3[/tex]

To solve for [tex]y[/tex], we can use substitution again:

[tex]y = 3(3)-1[/tex] (using the first equation given)

[tex]y=8[/tex]

Inequality is [tex]15 + p \le 44[/tex]

Choice A) 30 more passengers cannot board the plane. Only 29 more passengers can board the plane

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

Explanation:

15 people are already on the plane.

p is a placeholder for a positive whole number representing the additional number of people that can get on the plane.

In total, the plane holds 15+p individuals.

This expression's largest possible value is 44. Think of it as the ceiling. In terms of math, we call it the maximum. Since at most 44 people can be on the plane, this means the inequality we'll set up is [tex]15+p \le 44[/tex]

This says "15+p is less than or equal to 44". It's the same as saying "15+p is 44 or smaller".

---------------------------

To isolate p, we subtract 15 from both sides

Doing so leads to...

[tex]15+p \le 44\\\\15+p-15 \le 44-15\\\\p \le 29[/tex]

We can see that the largest p can get is 29, meaning that at most 29 more people can board the plane. There's no way that 30 people can board. That unfortunate 30-29 = 1 person must wait for another plane.

This all shows why choice A is the answer.

----------------------------

As a way to check the answer, we can note how p = 29 leads to 15+p = 15+29 = 44. We've filled the plane to full capacity.

If p = 30, then 15+p = 15+30 = 45, and we've gone 1 seat overboard.

Answer:

A multiple is a number that basically can be a number that can be divided by another number without a remainder.

Answer:

1. LCM of 7, 10 and 3 = 210

2. LCM of 15, 3 and 2 = 30

3. LCM of 7, 3 and 5 = 105

First, factorize each of the numbers:

[tex]7 = 1 * 7[/tex]

[tex]10 = 1 * 2 * 5[/tex]

[tex]3 = 1 * 3[/tex]

Multiply the factors the highest number of times it occur in any of the terms

[tex]LCM = 1 * 2 * 3 * 5 * 7[/tex]

[tex]LCM = 210[/tex]

Solving (2): LCM of 15, 3 and 2

First, factorize each of the numbers:

[tex]15 =1 * 3 * 5[/tex]

[tex]3 = 1 * 3[/tex]

[tex]2 = 1 * 2[/tex]

Multiply the factors the highest number of times it occur in any of the terms

[tex]LCM = 1 * 2 * 3 * 5[/tex]

[tex]LCM = 30[/tex]

Solving (3): LCM of 7, 3 and 5

First, factorize each of the numbers:

[tex]7 = 1 * 7[/tex]

[tex]3 = 1 * 3[/tex]

[tex]5 = 1 * 5[/tex]

Multiply the factors the highest number of times it occur in any of the terms

[tex]LCM = 1 * 3 * 5 * 7[/tex]

[tex]LCM = 105[/tex]

Solving (4): LCM of 4 and 7

First, factorize each of the numbers:

[tex]4 = 1 * 4[/tex]

[tex]7 = 1 * 7[/tex]

Multiply the factors the highest number of times it occur in any of the terms

1.25 x 1.75

(20/16) x (28/ 16)

The required blueprint dimensions of a room are given as 1.25 in.  × 1.75 in. Option C is correct.

As mentioned in the question,
The scale factor of 1 inch = 16 feet, dimensions of a room that is 20 feet * 28 feet.
Dimensions of a room on a blueprint is to be determined.

The scale factor is defined as the ratio of the modified change in length to the original length.

Here,
1 inch = 16 feet
1 feet = 1/16 inch,
Now,
Scaled dimensions,
= 20 (1/16) inch × 28 (1/16) inch
= 1.25 in × 1.75 in

Thus, The required blueprint dimensions of a room are given as 1.25 in.  × 1.75 in. Option C is correct.
