Please Help!! I don’t understand this!!

Answer:

Y+9>= -1

Step-by-step explanation:

The sum of a number y and 9 means that we wanna add Y and 9, but since y is a variable and 9 is just a number, we can't add them.

Now we have Y+9

Now, we plug in our inequality sign which is at least.

at least is >=

Now we have Y+9>=

And all you have to do is place the negative one after the inequality sign, and you get Y+9>= -1

Hope this helps! :)

Answer:

11) 1 3/8

12) 17/18

Step-by-step explanation:

Step-by-step explanation:

From the table we can make comparison between the distance travelled and the time taken. It can be seen that the time increases as the distance decrease.

If the car travels 700 miles in 0.5seconds and 600miles in 1.5secs, we can calculate the speed of the car using the formula;

v = change in distance/change in time

v = ΔS/Δt

v = 700-600/0.5-1.5

v = 100/-1

v = -100mi/hr

Since Speed = Distance/Time

-100 = 480/Time

Time = 480/-100

Time = -4.8s

Hence it will take the car 4.8seconds to travel 480miles.

Answer:

Yes, they are correct. Hernando divided 6 by 6.

Step-by-step explanation:

Given that:

Hernando ate 2/8 of a pizza for dinner.

Let the pizza be x. Then:

Hernando ate [tex]\dfrac{2}{8} \ \ o f \ \ x[/tex]

Then he gave the rest of the pizza to his friends

Hernando now carried out the  following calculations to support his activities;

[tex]\dfrac{6}{8} \div 6= \dfrac{6 \div 6}{8}= \dfrac{1}{8}[/tex]

[tex]\dfrac{6}{8} \times \dfrac{1}{6}= \dfrac{6 \div 6}{8}= \dfrac{1}{8}[/tex]

From the above calculation; we will see that Hernando divided 6 by 6 in both cases to get [tex]\dfrac{1}{8}[/tex].

Thus, the correct answer is:

Yes, they are correct. Hernando divided 6 by 6.

Answer:

A Yes, they are correct. Hernando divided 6 by 6. on edge

Answer:

2/3 or 66.6%

Step-by-step explanation:

Based on the information provided we see that there are a total of 3 sections that make up the entirety of the art room. Since the artwork will only be displayed on 2 sections out of the 3 that are available then there is 2/3 of the total amount of space available for the art section. In other words, only 66.6% of the art room is available for the art to be displayed on, while 33.3% is currently occupied and unavailable.

Answer:

3 1/9

Step-by-step explanation:

28/9=

9*3=27 r1

3 1/9

Answer: 3 1/9  

Step-by-step explanation:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 28 by 9 and keep only what is to the left of the decimal point:  28 / 9 = 3.1111 = 3

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.  28 - (9 x 3) = 1

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer.

Answer: the answer would be

ANSWER#2 The store charges $2 for a pizza and then adds on $3 for every topping added

assuming that the equation is The equation Cost = 3(number of toppings ) +2 that means that its the number of toppings times 3, so 3 dollars for every topping and than the additonal 2 dollars for the pizza cost

....and dang, I wish i could get a two dollar pizza :(

Answer:

The set of numbers 3 in, 4 in, and 5 in can form a triangle. a) is correct

Explanation:

A triangle is possible to be drawn only if the sum of the lengths of any two sides is greater than the length of the third side.

a) Is correct.

Testing all the posible combinations: 3+4>5, 4+5>3, 3+5>4. True. Hence, Option a is the correct choice,

b) Is incorrect

Since 1+7>8 is false, this choice is not correct

c) Is incorrect

Since 3+5>9 is false, this choice is not correct

Answer:

[tex]\boxed {\angle 1 = 45\textdegree}[/tex]

Step-by-step explanation:

First you need to write an expression by using the following equations from both [tex]\angle 1[/tex] and [tex]\angle 2[/tex] and solve for [tex]x[/tex]:

[tex]\angle 1 = 2x + 13[/tex]

[tex]\angle 2 = 8x - 83[/tex]

[tex]2x + 13 = 8x - 83[/tex]

-Solve:

[tex]2x + 13 = 8x - 83[/tex]

[tex]2x + 13 - 8x = 8x - 8x - 83[/tex]

[tex]-6x + 13 = -83[/tex]

[tex]-6x + 13 - 13 = -83 - 13[/tex]

[tex]-6x = -96[/tex]

[tex]\frac{-6x}{-6} = \frac{-96}{-6}[/tex]

[tex]x = 16[/tex]

After you have found the value of [tex]x[/tex], you need to apply the value of [tex]x[/tex] to the equation of [tex]\angle 1[/tex] and solve for the measurement of [tex]\angle 1[/tex]:

-The value of [tex]x[/tex]:

[tex]x = 16[/tex]

-Solve for the measurement of [tex]\angle 1[/tex]:

[tex]2x + 13[/tex]

[tex]2(16) + 13[/tex]

[tex]32 + 13[/tex]

[tex]45\textdegree[/tex]

-The measurement of [tex]\angle 1[/tex]:

[tex]\boxed {\angle 1 = 45\textdegree}[/tex]
