Write an equation to represent the following statement. j is 25 more than 3 Solve for j​

Answers

Answer:

j=3+25, here's the equation

Step-by-step explanation:

J=28

Answer:

j = 28

Step-by-step explanation:

Since we know that j is 25 more than 3, then we must know that 3+25= J (because J is 25 more/+ than 3) So, we simply solve 25+3 which equals 28.

A cellphone store has 120 cell phones in stock. Of these, 45 have keyboards. The manager of the store wants to add more cell phones with keyboards so that 40% of the stock has keyboards.

Answers

Answer:

5

Step-by-step explanation:

Let x be the number of cell phones with keyboards needed.

40% = [tex]\frac{40}{100}[/tex]

[tex]\frac{x+45}{x+120}[/tex] = [tex]\frac{40}{100}[/tex]

x+45 = 40 -----1

x+120 = 100 -----2

You would want to make the total of 1 the same as 2.

1×[tex]\frac{100}{40}[/tex]: 2.5+112.5 = 100 -----3

Now 2 and 3 are equal.

x+120 = 2.5x+112.5

Isolate the x and numbers.

120-112.5 = 2.5x-x

Simplify.

1.5x = 7.5

x = [tex]\frac{1}{1.5}[/tex] × 7.5

x = 5

The manager of the store needs to add 5 more cell phones with keyboards.

express 20cm as a percentage of 3m.
give your answer as a mixed number

Answers

Answer:

[tex]6\frac{2}{3}[/tex] %

Step-by-step explanation:

First, convert 3 meters into centimeters.

1m = 100cm

3m = 100 × 3 = 300cm

Now, form the fraction by putting the given value, 20cm, over the total measurement, 300cm.

[tex]\frac{20}{300}[/tex] = [tex]\frac{2}{30}[/tex] = [tex]\frac{1}{15}[/tex]  ⇒ Simplify your fraction to its simplest terms.

Next, multiply your simplified fraction by 100 to get your percentage.

[tex]\frac{1}{15}[/tex] × [tex]100[/tex] = [tex]\frac{100}{15}[/tex] = [tex]6\frac{10}{15}[/tex] = [tex]6\frac{2}{3}[/tex] %   ⇒ Simplify your percentage to its simplest terms.

Hope this helped! I would really appreciate it if you would please mark me brainliest!

20cm as a percentage of 3m as a mixed fraction is 6  2/3 %

let's convert centimetre to metre

1 cm = 0.01 m

20 cm = ?

cross multiply

length in metre = 20 × 0.01 = 0.2 m

Therefore,

0.2 m as a percentage of 3m is as follows:

0.2 / 3 × 100 = 20 / 3 = 6  2 / 3 %

need a answer asap

Answers

Answer

13x-37=112

13x =149

X=11.4

2y+7=41

Y=24

The value of x and y respectively will be 13° and 17°.

Based on the equation that's given in the question, the value of x will be found thus:

13x - 37 = 112

Collect like terms

13x = 112 + 37

13x = 149

x = 149/13

x = 13

Also, note that 2y + 7 = 41, therefore, the value of y will be:

2y = 41 - 7

2y = 34

y = 34/2 = 17°

Therefore, the value of x and y respectively will be 13° and 17°.

x = 2

Step-by-step explanation:

4(2x - 1) = 3x + 6

Simplify

8x - 4 = 3x + 6

Subtract 3x from both sides

8x - 3x - 4 = 3x - 3x + 6

5x - 4 = 6

Add 4 to both sides

5x - 4 + 4 = 6 + 4

5x = 10

Divide both sides by 5

5x/5 = 10/5

x = 2

Step-by-step explanation:

4(2x - 1) = 3x + 6

8x-4=3x+6

8x-3x=6+4

Which graph represents the polynomial function h(x) = x3 + 2x2 – 11x – 12?
y

Answers

Answer:

I attached a pic of the answer. I just did the quiz. Hope this helps!!!

Step-by-step explanation:

The graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.

Given that,
To determine the graph of the polynomial function h(x) =  x³ + 2x² - 11x -12.

What is the graph?

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
The graph of the function h(x) = x³ + 2x² - 11x -12 can be drawn as the function is a polynomial of degree 3 so it will follow two ups  and down,
So the graph can be drawn as shown in the image.

Thus, the graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.

Ronald said that (8.0 × 107) + (6.2 × 103) = 14.2 x 1010. Amy added the numbers too and said the sum was 8.00062 × 107. Ronald then added the numbers a second time and came up with his original result. Whose solution is correct? Ronald is correct because 80,000,000 + 6,200 = 142,000,000,000.

Yes No B
Amy is correct because adding the decimals and then adding the exponents is not the correct procedure for adding numbers in scientific notation.

Yes No C
Amy is correct because 6.2 × 103 is a much smaller number than 8.0 × 107, so the sum of the two numbers cannot be as large as a decimal times 1010.

Yes No D
Ronald is correct because when you add the exponents in 107 and 103, you get 1010.
