Answer:

80%

Step-by-step explanation:

160 of 200

160/200=0.8

move the decimal point over to the right 2 times

then u have 0.80

80%

Answer:

They are the same fraction. 5/4 in it's mixed form will be written as 2 1/2

Answer:

The fractions are the same. In mixed form, 5/4 will be written as 2 1/2.

Answer:

It simply means getting rid of the square root or radical in the denominator

Step-by-step explanation:

Rationalizing the denominator simply means getting rid of the square root or radical symbol in the denominator thereby making the denominator to be just a whole number.

For example if we want to rationalize the denominator in; 3/√2

We will multiply the numerator and the denominator by √2 to get rid of the radical in the denominator which is the square root sign.

Thus;

(3/√2) × (√2)/(√2)

This gives;

(3√2)2

Answer:

"To rationalize the denominator means to eliminate any radical expressions in the denominator such as square roots and cube roots." It is done usually by multiplying both numerator and denominator by the radical expression or another expression including the radical to be eliminated.

Answer:

  c  (all real numbers)

Step-by-step explanation:

The first inequality has the solution ...

  3 + v ≤ -4

  v ≤ -7 . . . . . . . subtract 3 from both sides

__

The second inequality has the solution ...

  -2v ≤ 14

  v ≥ -7 . . . . . . . divide by -2. Division by a negative reverses the inequality

__

So, the solution to the compound ...

  v ≤ -7  or  -7 ≤ v

is every number — all real numbers. The graph of that is the entire number line, as in choice C.

Answer:

15/14

Step-by-step explanation:

3(x+1/2)

10x-6=3x+3/2

7x=3/2+12/2

7x=15/2

x=15/2*1/7

x=15/14

Answer:

y = - [tex]\frac{3}{2}[/tex] x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (2, - 3) ← 2 points on the line

m = [tex]\frac{-3=0}{2-0}[/tex] = - [tex]\frac{3}{2}[/tex]

Since the line crosses the y- axis at (0, 0 ) ⇒ b = 0

y = - [tex]\frac{3}{2}[/tex] x ← equation of line

Step-by-step explanation:

Answer:

c - 7 < -18

Step-by-step explanation:

Seven subtracted from c :   c - 7

c - 7 < -18

Step-by-step explanation:

As it is said that the triangles are similar so the ratio of the corresponding sides are equal so

AB / ED = BC / EF

x² / 18 = 7 / 14

x² / 18 = 1 / 2

2x² = 18

x² = 18 / 2

x² = 9

x² =( + 3)²

Therefore

x = 3 or x = - 3

Explanation:

given 7 - 2x

if x=-3

7-2(-3) = 7+6 = 13

Answer:

Step-by-step explanation:

when x = - 3

7 - 2x

= 7 - 2 *( - 3)

Answer:

-2

Step-by-step explanation:

5(2z + 4) = 0

Divide both sides by 5.

2z + 4 = 0

Subtract 4 from both sides.

2z = -4

Divide both sides by 2.

z = -2

Answer:

Z=-2

Step-by-step explanation:

5(2z+4)=0

2z+4=0/5=0

2z=0-4=-4

z=-4/2=-2

z=-2
