Bye

Answers

Answer 1

Answer:

#1) 4x (less than or equal to) 320

#2) B (5 - 2 = 3 , 70

#3) -10.5

Hope this helps!

Step-by-step explanation:

Answer 2
1)

Ms. Sung is not able to spend more than 320 per month.

The best inequality for this would be

320 - 4x ≥ 0

Where x is the amount she spends per shopping trip

2)

x = 5 so let’s plug in 5 for x

It seems as if your inequalities glitched so I’m unable to help you directly.

a.
-2(5) (something) 12
-10 (something) 12

If it’s the less than symbol, then it is true
If it is the greater than symbol, then it is false
If it’s the less than or equal to symbol, it is true
If it’s the greater or equal to than symbol, then it is false

b.

(5) - 2 (something) 7
3 (something) 7

If it’s the less than symbol, then it is true
If it is the greater than symbol, then it is false
If it’s the less than or equal to symbol, it is true
If it’s the greater or equal to than symbol, then it is false

c.

2(5) (something) 12
10 (something) 12

If it’s the less than symbol, then it is true
If it is the greater than symbol, then it is false
If it’s the less than or equal to symbol, it is true
If it’s the greater or equal to than symbol, then it is false

d.

(5) - 7 (something) 2
-2 (something) 2

If it’s the less than symbol, then it is true
If it is the greater than symbol, then it is false
If it’s the less than or equal to symbol, it is true
If it’s the greater or equal to than symbol, then it is false

3)

-4x = 42
Divide by -4

x = -10.5

To solve for x we need to get it by it’s self.

So let’s multiply 4 on both sides:

x = (5•4)/6

x = 20/6 = 10/3 = 3.33333333

Eddie is going to flip a coin and spin a spinner. The coin has a heads and a tails. The spinner has three equal parts that are yellow, blue, and green. What are the chances that Eddie gets heads and blue on the spinner?

A. 1/2
B. 1/3
C. 1/5
D. 1/6

Answers

Answer:

C. 1/5

Step-by-step explanation:

the chances that Eddie gets heads and blue on the spinner is [tex]\frac{1}{6}[/tex]  such that the spinner has three equal parts that are yellow, blue, and green.

Probability

The possibility of the occurrence of an event is the concept of probability.

How to find the probability of the event?

Find the probability of the event that Eddie gets head.

The total number of outcomes in a coin that has a head and a tail is 2 and the chance in which Eddie will get the heads will be once.

So, the probability of the event that Eddie gets head will be [tex]\dfrac{1}{2}[/tex].

Find the probability of the event that Eddie gets blue.

Now, the total number of outcomes in the spinner will be 3 as the spinner has three equal parts and the chances of blue on the spinner will be once.

So, the probability of the event that Eddie gets blue on the spinner is [tex]\dfrac{1}{3}[/tex].

Find probability of the event that Eddie gets heads and blue

Then, the chances that Eddie get heads and blue on the spinner will be [tex]\frac{1}{2} \times\frac{1}{3} =\frac{1}{6}[/tex]

So, the chance will be [tex]\frac{1}{6}[/tex].

Thus, option C. [tex]\dfrac{1}{6}[/tex] is the correct option.

The graph represents the cost y (in dollars) to open an online gaming account and buy x games. Write an equation in slope-intercept form that represents the graph.

Answers

Answer:

y = 10x + 15

Step-by-step explanation:

you pick two points on the line

I picked (3,45) and (6,75)

you subtract the two x’s and y’s

75 - 45 = 30 (30 is the rise) you go up from 45 to 75

6 - 3 = 3 (you move 3 times to the right to get to the 6) so 3 is the run

slope = rise/run so 30/3 = 10

The y-intercept is the place you start on the graph so that is 15

Work:

In this diagram the big square is divided into 7 congruent small squares and two congruent triangles. The area of the shaded square is 4sq cm. What is the area of the shaded triangle?

PLS HELP. PLS TELL ME HOW YOU GOT THE ANSWER TOO!

Answers

Since each square will have an area of 4 cm^2 because they are congruent, then let’s find the side length of them.

Square root of 4 is two

Each side is 2 cm. Since the unshaded triangle has 3 on the base and height, then it is same to assume that the triangle has a base of 6 cm (2 * 3) and a height of 6 cm.

The formula of the area of a triangle is:
1/2 ( base times height)

Let’s plug in some values

1/2(6 * 6)

Multiply

1/2 (36)

Divide

18

Since the triangles are also congruent, then the shaded side has the same area.

The shaded triangle has an area of 8 cm ^2
