How do i solve the inequality & put it on a number line.|3x + 11 > 2

Answer:

ºC = (ºF - 32) / (9/5)

Step-by-step explanation:

Take the formula that you already have:

ºF = (ºC × 9/5) + 32

Flip the ºF and ºC:

ºC = (ºF × 9/5) + 32

Move the whole number to the right side of the equation and change it's sign:

ºC = (ºF - 32) / (9/5)

(This will also force the fraction to move to the right hand side of the equation, but for that you keep the value of the number the same)

Answer:

Valeria should use the reward worth $2 off her next purchase.

Step-by-step explanation:

To find the answer, you have to determine what Valeria would pay with each discount:

-reward worth $2 off her next purchase:

$7.50-$2=$5.50

-Save 15% coupon:

$7.50*0.15=$1.125

$7.50-$1.125=$6.375

According to this, the answer is that Valeria should use the reward worth $2 off her next purchase as she will pay $5.50 and with the save 15% coupon she would have to pay $6.375.

i think u multiply them i hope thats right srry if its not

Answer:

x > -3, x >7

Step-by-step explanation:

for -2x < 6:

first divide each side by 2: -x < 3

then divide each side by -1, so the final answer is: x > -3

(whenever you divide by a negative number you have to flip the sign)

for 4x-7>21:

first, add 7 to each side: 4x>28

then divide each side by 4, and the final answer is: x >7

Answer:

ok i know this is correct %100 it is D

Step-by-step explanation:

this is because if u have 8/20 and reduce by four do divide 8 by four and 20 by four that would be 2/5!!

IF THIS HELPED PLZ GIVE ME BRAINIEST!!

Answer:

2 / 5

Step-by-step explanation:

8/20 simplifies to 2/5. Simply divide 8 and 20 by 4 and you get your simplified fraction.

Answer:

-.32

Step-by-step explanation:

Answer:

The expression  -10 - (-4) represents the given diagram.

Step-by-step explanation:

Here, the total number of blue boxes marked with (-) = 10

So, in Total number of (-) are 10 x (-1) = -10

Now, the number of boxes crossed out = 4

So, the total value crossed out = 4 x ( Value on each box) = 4 ( -1) = -4

⇒ The value Left after crossing  = Total value - The crossed out value

                                                       = -10 - (-4)

Hence, the expression  -10 - (-4) represents the given diagram.

(3, 6)

Step-by-step explanation:

If you create a mini graph, like I did, you would have seen that the middle point is at the co-ordinates (3,6). I have attached a image to this reply, with my "graph". (Sorry if its a little ugly, but that doesn't matter, the math does.)

Answer:

x=5±√2

Step-by-step explanation:

x^2-10x=-23

x^2-10x+25=-23+25

(x-5)^2=2

x-5=±√2

x=5±√2

Answer: 35° and 55°

Step-by-step explanation:

For complementary angle, their total value equals to 90°.

Let the measure of the angle be y.

Therefore the complement will be:

= 90° - y

The measure of an angle plus twice its complement is equal to 145 can be expressed as:

y + 2(90 - y) = 145

y + 180 - 2y = 145

y = 180 - 145

y = 35°

The angle is 35° and its complement will be:

= 90 - y

= 90 - 35

= 55°

Answer:

Step-by-step explanation:

yes you can

the form of the equation is y=mx+b

the y intercept (0,b) when x=0 the y=b

and if you know the slope m, then you can form the equation

example : m=3 , and y intercept is (0,1)

y=mx+b

y=3x+b ( at point (0,1)

1=3(0)+b

b=1

the equation is y=3x+1

Step-by-step explanation:

Answer:

4.8 gallons of water.

Step-by-step explanation:

Mai is filling his fishing tank with water. This shows a proportional relation between the time and the amount of water filled.

Amount of water filled (In gallons) ∝ Duration (In minutes)

w ∝ t

w = kt  ---------(1)

For t = 0.5 gallons,

Amount of water = 0.8 gallons

From equation (1),

0.8 = k(0.5)

k = 1.6

So the proportionality equation will be,

w = 1.6t

Now we have to find the amount of water filled in 3 minutes.

w = 1.6 × 3

   = 4.8 gallons

Therefore, water filled in the tank after 3 minutes = 4.8 gallons.

Given:

Speed of train = 85 miles per hour

Total distance = 102 miles

To find:

The time taken by train to cover 102 miles.

Solution:

We know that,

[tex]Speed=\dfrac{Distance}{Time}[/tex]

On substituting the values, we get

[tex]85=\dfrac{102}{Time}[/tex]

[tex]Time=\dfrac{102}{85}[/tex]

[tex]Time=1.2[/tex]

Therefore, the time taken by train to cover 102 miles is 1.2 hours.

Answer:

it would take 20 months and it would cost $6450

Step-by-step explanation:

in order to solve this question we need to equate the amount at each dealer against one another

make the months as an unknown variable (x)

2450 + 200x = 2950 + 175x

now make x the subject of formula

200x - 175x = 2950 - 2450

25x = 500

x = 500/25

x = 20

the amount would be the same in 20 months

replace x with 20

2450 + 200 (20) = 6450

$6450

Answer:

D

Step-by-step explanation:

The relantionship is perpendicular, because when you do the procedure that the question talks about, you find a circumference, and A and B are points of that cirumference.

As the segment is her diameter, we know that they, the points A and B, are perpendicular to the segment.

Why?

Because the definition of a circumference is:

> A single point in a bidimensional space that has the same distance from a infinity amount of points - remember that a point has no dimension, so there is infinity points over one point -, what became to be a circumference.

Also, take note that the lower distance for any point is a straight segment, who is perpendicular for both points.

But talk maybe do not help. Look the annex.
