Answer:

[tex]x>-5[/tex]

Step-by-step explanation:

[tex]\frac{-1}{5} x+1<2[/tex]

Subtract 1 from both sides

[tex]\frac{-1}{5} x+1-1<2-1[/tex]

Simplify

[tex]\frac{-1}{5} x<1[/tex]

Multiply both sides by -1, which reverses the inequality also

[tex]\frac{-1}{5} x(-1)>1(-1)[/tex]

Simplify

[tex]\frac{1}{5} x>-1[/tex]

Multiply both sides by 5

[tex]5*\frac{1}{5} x>5(-1)[/tex]

Simplify

[tex]x>-5[/tex]

Answer:

a negative plus positive equals a negative-

Answer:

"To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values. The result takes the sign of the integer with the larger absolute value. The sum of any integer and its opposite is equal to zero."

Step-by-step explanation:

Simpler Explanation: If you add a positive number with a negative number, the sign (negative/positive) of the sum is the same as the integer (number) with the largest absolute value. For example;

1. 10 + -12 = -2

Here, the sum has the same sign (negative) as the largest number in the equation (-12).

2. 7 + -3 = 4

Here, the sum has the sign (positive) as the largest number in the equation (7).

Answer:

The third statemnet

Step-by-step explanation:

I say the third statement is correct because it says its 31.2 degrees above 0 which is positive. Also it says in the morning it was 6.7 below 0 which is negative which equlas-6.7. So that is why statement 3 is the correct answer.

x=-2,y=-2

Step-by-step explanation:

x+y=-4

x=-4-y--(3)

substitute (3) in (1)

5(-4-y) -3y=-4

-20-5y-3y=-4

-8y=16

y=16/-8

y=-2

substitute y in (3)

x=-4-(-2)

x=-2

Answer:

The midpoint is (-1, 1.5)

Step-by-step explanation:

To find the x coordinate of the midpoint, average the x coordinates of the endpoints

(2+-4)/2 = -2/2 = -1

To find the y coordinate of the midpoint, average the y coordinates of the endpoints

(-3+6)/2 = 3/2 = 1.5

The midpoint is (-1, 1.5)

Answer:

[tex]\frac{1}{64}[/tex]

Step-by-step explanation:

Using the rule of exponents

[tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]

and 4³ = 4 × 4 × 4 = 16 × 4 = 64

Then

[tex]4^{-3}[/tex] = [tex]\frac{1}{4^{3} }[/tex] = [tex]\frac{1}{64}[/tex]

Answer: 8.25mi

Step-by-step explanation:

Just add them all together

8.25 mi

Step-by-step explanation:

2.75 mi + 3 mi + 2.5 mi

= (2.75 + 3 + 2.5)mi

= (5.75 + 2.50)mi

= 8.25 mi

x = 72

y = 54

z = 54

================================================================

The regular pentagon has all five sides the same length. It also has all interior angles the same measure. This leads to y = z. These two angles are the congruent base angles of the isosceles triangle. The base angles are opposite the congruent sides.

The fact that we have a regular pentagon also means that the five triangles shown are identical copies of one another (i.e. they are congruent triangles). Divide the full 360 degree rotation into 5 parts to get 360/5 = 72, which represents the measure of the central angle x.

--------------

For any triangle, the three angles always add to 180. This means,

x+y+z = 180

72+y+z = 180 .... plug in x = 72

72+y+y = 180 ... recall that y = z

2y+72 = 180

2y = 180-72

2y = 108

y = 108/2

y = 54, which is also the measure of angle z as well

--------------

As a quick check,

x+y+z = 72+54+54 = 180

which helps confirm the answer.

Step-by-step explanation:

I can't draw here, but I can describe :

an isoceles triangle means that 2 sides of the triangle are equally long (they are typically called the "legs" left and right on top of the baseline).

this fact makes the triangle symmetrical.

and that means that 2 angles are also equal (the angles of the legs with the baseline).

so, knowing that one angle is 34 degrees can mean 2 things :

either 34 degrees is the angle between the 2 legs, or it is one of the 2 equal angles between legs and baseline.

as we know the sum of all angles in a triangle is always 180 degrees.

so case 1 : 34 degrees is the angle between the legs

180 = 34 + 2×base-leg-angle

144 = 2×base-leg-angle

each base-leg-angle = 72 degrees

case 2 : 34 degrees is one of the base-leg-angles

180 = 2×34 + between-the-legs-angle

180 = 68 + between-the-legs-angle

between-the-legs-angle = 112 degrees

so, you need to draw one triangle for each case.

since we don't know anything about the side lengths, size does not matter. only the angles need to be correct :

one triangle with 34, 72, 72 degrees

and one triangular with 34, 34, 112 degrees

Answer:

Step-by-step explanation:

3/5 = 0.6

1/2 = 0.5

it has to be in between these two numbers

5 x 0.11 = 0.55

Answer:

Step-by-step explanation:

It is between 0.4 and 0.6

It is greater than 1/2. That means that the starting point is 0.5 to 0.6

The final clue should nail it. It is a multiple of 0.11. That means it is 0.55. One possible answer is 11/20
