Answer:

3 * 1.4 = 4.2

Answer:

about 2,546

Step-by-step explanation:

Answer:

the answer is the 2nd one

Step-by-step explanation:

Just subtract the sum of 1/4 and 1/3 on 1

.

1 - [(1/3) + (1/4)]

Get the least common denominator. LCD = 12

= 12/12 - [(4/12) + (3/12)]

= 12/12 - (7/12)

= 5/12

.

Therefore, 5/12 of the tank is empty.

Answer:

-17

Step-by-step explanation:

ok well I can't really see Sam and John's answer but -3-14 is equal to -17

if you see that there's a negative in front of the first number and its also subtracting you have to make that subtract sign an addition sign then change the second number to a negative like this:

-3+-14 then you just add.

With Sam and John whichever one had -17 as their answer is correct

Answer:

This depends on the drop downs but its probably this:

1. Coefficient

2. Factor (I changed this one after the asker said what options there are)

3. Constant

Answer:

In the first term, 3 is a coefficient

In the second term, (x + 2) is a factor

In the last term, 4 is a constant

Answer: 12

Step-by-step explanation:

Let p represent this unknown amount.

Nari pours three-fourths of this volume into an empty pot. This can be written as:= 3/4 × p = 3/4p = 0.75p

She then adds another 2 pints of water and the pot now holds a total of 11pints of water. This means we will add 2 to 0.75p and equate to 11. This will be:

0.75p + 2 = 11

0.75p = 11 - 2

0.75p = 9

p = 9/0.75

p = 12

P equals to 12

This question is based on solving linear equation.Therefore, the answer is 12 pints of total amount of water.

Given:

Nari pours three-fourths of this volume into an empty pot.She then adds another 2 pints of water. The pot now holds a total of 11 pints of water.

Let the unknown amount of pints of water is  p.

According to the question,

She pours three-fourths of this volume into an empty pot. This can be written as:

[tex]\dfrac{3}{4}\times p= \dfrac{3}{4} p = \bold{0.75p}[/tex]

She add on  2 pints of water  to 0.75 p in pot, then it becomes  total of 11 pints of water.

In ,mathematically expressed as,

[tex]\begin{alligned}0.75p+2&=11\\0.75p&=11-2\\0.75p&=9\\p&=\frac{9}{0.75}\\\bold{p&=12}\end{alligned}[/tex]

Therefore, there is total amount of 12 pints water.

Answer:

x=4

Step-by-step explanation:

5x-x=15+1

4x÷4=16÷4

x=4

The solution to the given linear equation with one variable is 4.

The given equation is 5x-1=x+15.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Here, the equation can be solved as follows

5x-1=x+15

5x-x=15+1

4x=16

x=16/4

x=4

Answer:

D. [tex]y = 2x[/tex]

Step-by-step explanation:

A proportional relationship is represented by the formula [tex]y = mx + b[/tex].

m = the slope, which is  [tex]\frac{y_{2}-y_{1} }{x_{2} - x_{1}}[/tex].

b = the y-intercept, the point where the line crosses the y-axis. We actually don't have to worry about the [tex]+ b[/tex] part of the formula because [tex]b = 0[/tex], so it can be left out.

To find the slope, use [tex]\frac{y_{2}-y_{1} }{x_{2} - x_{1}}[/tex]. Subtract the smaller y value (2) from the larger y value (6).

(6 - 2 = 4)

Then subtract the smaller x value (1) from the larger x value (3).

(3 -  1 = 2)

So it looks something like this now:

[tex]\frac{6-2}{3-1}[/tex] , which equals [tex]\frac{4}{2}[/tex]

Then you divide the top part of the fraction (4) by the bottom part. (2).

[tex]\frac{4}{2}[/tex] = 2. The slope (m) is 2.

So the final equation is [tex]y=2x[/tex].

Students in a pre-algebra class are given the polynomial 12x²y - 6xy +18y² and told to factor out the greatest common factor.

Which student has made the correct choice? (1 point)

a) Delia chose 3y because she said that it was a factor of every term.

b) Pedro chose y because he said that the greatest common factor can be found only by looking at the variable terms.

c) Mike chose 6y because he said that it was the largest factor of every term. d) Marisol chose 6 because she said that it was the only greatest common factor in each term.

Answer:

c) Mike chose 6y because he said that it was the largest factor of every term.

Step-by-step explanation:

Step 1

Identify the GCF of the coefficients.

12x²y - 6xy + 18y²

Coefficients are :

12, 6, 18

The Greatest Common Factor for 12, 6, 18 =

The factors of 6 are: 1, 2, 3, 6

The factors of 12 are: 1, 2, 3, 4, 6, 12

The factors of 18 are: 1, 2, 3, 6, 9, 18

Then the greatest common factor is 6.

Step 2

Identify the GCF of the variables.

x²y , xy, y²

The GCF of these variables is y

Step 3

Combine to both GCF's to obtain the GCF of the expression.

= 6 × y

= 6y

The Greatest Common Factor for the expression 12x²y−6xy + 18y² is 6y

Step 4

We factorise

= 12x²y−6xy + 18y²

= 6y(2x² - x + 3y)

Therefore, Option c) Mike chose 6y because he said that it was the largest factor of every term is the correct option.

Mike is correct.

Answer:

h =10

Step-by-step explanation:

3/7 = h/14 -2\7

3/7 = 1/14 h + -2/7

1/14 h + -2/7 = 3/7

1/14 h + -2/7 +2/7 = 3/7 + 2/7

1/14 h = 5/7

14 * ( 1/14h) = 14* (5/7)

h =10

Answer:

  18 square meters

Step-by-step explanation:

The area of a trapezoid is given by the formula ...

  A = 1/2(b1 +b2)h

The bases are the parallel line segments, and the height is the perpendicular distance between them.

  A = (1/2)(7 m + 5 m)(3 m) = 1/2(12 m)(3 m) = 18 m^2

The area of the trapezoid is 18 square meters.

Line GH bisects angle FGI, that means angle FGH = angle HGI

the value of x and angle FGI

angle FGH = angle HGI

6x - 11 = 4x + 7

or, 6x - 4x = 7 + 11

or, 2x = 18

or, x = 18/2 = 9

angle FGI = angle FGH + angle HGI

or, angle FGI = 6x - 11 + 4x + 7

or, angle FGI = 10x - 4

By putting the value of x, we get

angle FGI = 10(9) - 4

or, angle FGI = 90 - 4 = 86°

The value of x is 9.

Angle FGI = 86°
