can you help me with this question I need the answers,please.

Answer:

X=-3

Step-by-step explanation:

To find the unknown variable: X, we need to see how mich 4x equals to. to do this, we must first subtract 3 from both sides of the equation. The left side will be left with -12, and the right side will be left with 4x. This means:

-12=4x So...

x=-3

To check if this is right, you can subsitute this back into the equation.

4 times -3= -12. -12=3=-9

Answer:

Worker 2 : 10 feets above roadway

Worker 4 : standing on roadway

Worker 1 : 7 feets below roadway

Worker 3 : 10 feets below roadway

Step-by-step explanation:

Given the question :

Four workers are repairing a bridge. Show the workers locations from highest to lowest position in relation to the roadway. worker 1 is 7 feet below the roadway worker 2 is 10 feet above the roadway worker 3 is 10 feet below the roadway worker 4 is standing on the roadway

Worker 1 : 7 feets below roadway

Worker 2 : 10 feets above roadway

Worker 3 : 10 feets below roadway

Worker 4 : standing on the roadway

Highest to lowest position in relation to the bridge :

Worker 2 : 10 feets above roadway

Worker 4 : standing on roadway

Worker 1 : 7 feets below roadway

Worker 3 : 10 feets below roadway

Answer:

The 2 above the 10 is called a power. It means 10 times itself twice. So 10 times 10 is 100. 3050/100=30.5

Answer:

Step-by-step explanation:

Given that the cost of cooler is $44

money given to the two sons $50

let S represent the amount the two son will have to share equally

the change is 50-44=6

=$6

Then s=6/2=$3

applying with the expression directly we have

S = (50 - 44)/2

S = (6)/2

S=$3

Answer:

$680

Step-by-step explanation:

Capacity of the truck: 4200 pounds and 480 cubic feet of cargo.

Small package: 25 pounds and 3 cubic feet each.

Large package: 50 pounds and 5 cubic feet each.

For x number of small packages:

25x pounds and 3x cubic feet

Let x = 8,

200 pounds and 24 cubic feet.

For y number of large packages:

50y pounds and 5y cubic feet

Let y = 80,

4000 pounds and 400 cubic feet.

Since delivery service charges $5 for each small package and $8 for each large package.

The maximum revenue per truck = ($5x + $8y)

                                                       = ( $5 x 8) + ($8 x 80)

                                                       = $680

Answer:

The technical writer should expect his annual pay to decrease by $1,059

Step-by-step explanation:

52 weeks = $55,068

51 weeks =

Cross Multiply

51 weeks × $55,068/52 weeks

= $54009

The writer will be paid $54009 for 51 weeks

His pay reduced by:

$55,068 - $54,009

= $1,059

The correct form of the partial fraction decomposition for the expression (13x - 7)/((x + 2)(4x - 3)) is;

Option B; [A/(x + 2)] + [(Bx + C)/(4x - 3)]

The given complex fraction is;

(13x - 7)/((x + 2)(4x - 3))

      Now partial fractions are simply decomposition of complex fractions into simpler fractions. For example we want to decompose the complex fraction;

4/[(x - 1)(x + 5)]

The right format will be;

[A/(x - 1)] + [B/(x + 5)]

Applying this same pattern above to our question, we can decompose the fraction (13x - 7)/((x + 2)(4x - 3)) into;

[A/(x + 2)] + [(Bx + C)/(4x - 3)]

In conclusion, the correct answer is Option B.

Answer:

0.4 or a 40% Chance. Because its 4/10.

Answer:

f(x)=y.

Explanation

In a function, f(x) means "the function of x". For example, f(x)=2x is the same thing as y=2x. But f(y) would be something different entirely, because that would be using the function definition to change the y-value.

Answer:

noooooo thx

Step-by-step explanation:

Answer:

let the $12 dish be x and the other y

x + y = 12 <--- 1

12x + 10.50y= 138 <--- 2

multiply equation 1 by 12

so now we have

12x + 12y = 144

12x + 10.50y = 138

now subtract each one and that cancels out x

1.5y = 6

y = 4

now subsitute that into any equation

x + 4 = 12

x = 12 - 4

x = 8

Answer: 60 cents

Step-by-step explanation: 1 Dime= 10 cents; 10x6= 60.

Answer: 60 cents.

Step-by-step explanation:

One dime is worth 10 cents. Therefore, if you have six of them it's simple repeated addition

10+10+10+10+10+10

or simple multiplication.

10(6)

Which are both the same exact thing.

So six dimes are 60 cents. Hope that helps!!

Answer: 2.4

Step-by-step explanation:

10 divided by 5 = 2
