The difference of a number and -6 is less than 9 write an inequality and solve

Pavlova-9 [17]

Answer:

n - (-6) < 9

n < 3

Step-by-step explanation:

When setting up an inequality, using the key words from the problem will help. The word 'difference' would indicate subtraction and 'less than' would be the '<' inequality sign. Since the expression is 'the difference of a number and -6', we write:

n - (-6) < 9

Whenever we subtract a negative number, we change both signs to positive:

n + 6 < 9

Using inverse operations to solve: n + 6 - 6 < 9 - 6

n < 3

Alan says that the distance from Hadley to Greenville is 16 miles. Is he correct?Explain

yuradex [85]

Answer:

Step-by-step explanation:

Considering the complete question attached in figure.

Consider

Hadley = x

Parker = y

Greenville = z

Distance between Greenville and Parker = yz = 29

Given that distance between Hadley and Greenville is 13 miles less than the distance between Parker and Greenville.

xz = yz -13 --- (1)

Distance between hardley and greenville = xz = ?

From (1)

xz = 29 -13

xz = 16 miles

So Alan is right that distance between Hadley and Greenville is 16 miles

Question 4 of 5

Arturiano [62]

Answer:

D. 9 cm

Step-by-step explanation:

The radius of the sphere can be found by solving the volume equation for the radius.

V = 4/3πr³

3V/(4π) = r³

r = ∛(3V/(4π)) = ∛(3×3052/(4×π)) ≈ ∛728.611

r ≈ 9.0 cm

The radius of the sphere is about 9 cm.

What is the value of x?<br>30<br>45<br>55<br>60

KATRIN_1 [288]

Answer:

$\boxed {\tt B. \ x=45}$

Step-by-step explanation:

x and 3x are on a straight line together. Therefore, they are supplementary and must add to 180 degrees.

Add x and 3x, and set that equal to 180.

$x+3x=180$

Combine like terms on the right side of the equation. Both x and 3x have a variable, so they can be added together.

$(x+3x)=180$

$4x=180$

Since we want to find x, we have to isolate x. x is being multiplied by 4. The inverse of multiplication is division. Divide both sides of the equation by 4.

$\frac{4x}{4} =\frac{180}{4}$

$x=\frac{180}{4}$

$x=45$

x is equal to 45, so the correct answer is B. 45
