Answer:

(2 x 4) - 8

Step-by-step explanation:

Answer: 1 5/7

Step-by-step explanation:

First lets simplify 2/5x1/4,

-> 8/20x5/20

-> 40/20

-> 4/2

Now lets calculate:

42÷−7−6=?

In the second fraction, the negative numerator and negative denominator cancel each other.

The equivalent equation is

42÷76=?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

42×67=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

4×62×7=2414

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 24 and 14 using

GCF(24,14) = 2

24÷214÷2=127

The fraction

127

is the same as

12÷7

Convert to a mixed number using

long division for 12 ÷ 7 = 1R5, so

127=157

Therefore:

42÷−7−6=157

Solution by Formulas

Apply the fractions formula for division, to

42÷−7−6

and solve

4×−62×−7

=−24−14

A negative over a negative becomes positive

=2414

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(24,14) = 2

24÷214÷2=127

Convert to a mixed number using

long division for 12 ÷ 7 = 1R5, so

127=157

Therefore:

42÷−7−6=1 5/7

(Sorry for the 157s I meant 1 5/7)

Answer:

  (d)  x = 3

Step-by-step explanation:

The "vertex form" of the equation of a parabola is ...

  y = a(x -h)² +k

In this form, the vertex has coordinates (h, k).

Comparing the form to your equation, you see that h=3, k=4, so the vertex is (h, k) = (3, 4).

The line of symmetry is a vertical line through the vertex. It will have the same x-value as the x-coordinate of the vertex:

  x = 3

_____

In short, the equation of the line of symmetry has its constant equal to the opposite of the value added to x. Here, the added constant is -3, so the line of symmetry is x=3.

The values h and k in the vertex-form equation represent the amount of translation right and up from the parent function graph. When the graph is translated 3 units to the right, the line of symmetry moves from x=0 to x=3.

Answer:

Lines 1 and 2 are parallel because they have the same slope

Step-by-step explanation:

slope of line 1 = 1/2

slope of line 2 = 1/2

slope of line 3 = 4

slope of line 4 = 14

how to find slope of line 2, solve for 'y':

x - 2y = -1

-2y = x - 1

y = 1/2x + 2

how to find slope of line 4, simplify for 'y':

y + 3 = 1/4x - 1/4(6)

y = 1/4x - 6/4 - 3

y = 1/4x -6/4 - 12/4

y = 1/4x - 18/4

Answer:

48.14= $58.25

$97.92= 81.27 euro

Step-by-step explanation:

Giving the following information:

1 Euro is currently valued at 1.21 U.S. Dollars.

First, we need to calculate the dollar value of 48.14 euros.

Proportion equation used for answer below: 1e= 1.21d

48.14*1.21= $58.25

Now, the euro value of 97.72 dollars.

Proportion equation used for answer below: (1:1.21) 0.83

1 dollar equals 0.83 euro.

97.92*0.83= 81.27 euro

Answer:

option a 21 is the right answer

Step-by-step explanation:

7/12.36

12 into 3 is 36

so 12 1's are and 12 3's are

now it'll become 7 into 3

which is 21

therefore 21 is the answer

1). 24

2). 27

3). 5

PICTURE 1:

The answer is 24: (13 7/10) Rounded To The Nearest Whole Number is: (14)

[tex]13 \frac{7}{10} = 14[/tex]

AND,

(10 1/8) Rounded To The Nearest Whole Number is: (10)

[tex]10 \frac{1}{8} = 10[/tex]

So, 14 + 10 = 24

______________________________________

PICTURE 2:

The answer is 5: (8 1/5) Rounded To The Nearest Whole Number is: (8)

[tex]8 \frac{1}{5} = 8[/tex]

AND,

(2 7/8) Rounded To The Nearest Whole Number is: (3)

[tex]2 \frac{7}{8} = 3[/tex]

So, 8 - 3 = 5

PICTURE 3:

The answer is 27: (58 5/12) Rounded To The Nearest Whole Number is: (58)

[tex]58 \frac{5}{12} = 58[/tex]

AND,

(30 5/7) Rounded To The Nearest Whole Number is: (31)

[tex]30 \frac{5}{7} = 31[/tex]

So, 58 - 31 = 27

Answer:

Area = 1808.64 cm

Step-by-step explanation:

Circumference of a circle = 2πr

Circumference = 150.72

π = 3.14

r = radius

150.72 = 2 x 3.14 x r

150.72 = 6.28 r

r = 150.72/6.28

r = 24cm

Radius = 24

Area of a circle = πr²

Area = 3.14 x 24²

Area = 3.14 x 576

Area =1808.64 cm

Answer:

1808.64 cm

A (2, 4)

B (-6, 4)

C (-6, 2)

D (2, 2)

Step-by-step explanation:

If it is being reflecting across the y-axis, the rule is this:

(x, y) ---> (-x, y)

So...

A (-2, 4) ---> (2, 4)

B (6, 4) ---> (-6, 4)

C (6, 2) ---> (-6, 2)

D (-2, 2) ---> (2, 2)
