Answer:
240
Step-by-step explanation:
20% of the students like rock and 40% like hip-hop. That means that 60% of the 360 students would be expected to choose one of the two. Because you don't know the other 10%, you would assume that they would have the same ratio of students who like the country to those who like rock and hip-hop. 60 is 2/3 of 90, so you would expect 2/3 of the students to like hip-hop or rock. 2/3 of 360 is 240.

Write an equation for the following graph.
Answer:
y = 25x
Step-by-step explanation:
slope is 25 because to move from one point to another (on the line) you move up 50 (from 0 to 50) and to the right 2 (from 0 to 2) slope is 50/2 which simplified to 25
when x = 0, y = 0 so the y intercept is 0 but it isn’t necessary to add it to the equation
Answer:
y=25x

A rectangle with a length of x+5 has a perimeter of 4x+ 14. What is the width of the rectangle?
What i put before is wrong sorrI
Length of the rectangle (l) = x + 5
Perimeter of the rectangle = 4x + 14
Formula of perimeter of the rectangle = 2(length + width)
Let the width of the rectangle be 'w'. So,
[tex] \rm \longrightarrow 2(l + w) = 4x + 14 \\ \\ \rm \longrightarrow 2(x + 5 + w) = 4x + 14 \\ \\ \rm \longrightarrow \dfrac{2(x + 5 + w)}{2} = \dfrac{4x + 14}{2} \\ \\ \rm \longrightarrow x + 5 + w = 2x + 7 \\ \\ \rm \longrightarrow x + 5 + w - (x + 5) = 2x + 7 - (x + 5) \\ \\ \rm \longrightarrow x - x + 5 - 5 + w = 2x - x + 7 - 5 \\ \\ \rm \longrightarrow w = x + 2[/tex]
[tex] \therefore [/tex] Width of the rectangle (w) = x + 2

5(7x-2)=60
Please show your work and explain how!
Do it quickly please
Answer: hope this helps <3
x=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(7x−2)=60
(5)(7x)+(5)(−2)=60(Distribute)
35x+−10=60
35x−10=60
Step 2: Add 10 to both sides.
35x−10+10=60+10
35x=70
Step 3: Divide both sides by 35.
=35x/35
=70/35
Answer:
5(7X-2)=60
First distribute the 5 so the new equation is 35x-10=60
Then add 10 on both sides +10 +10
___________
The new equation is 35x= 70
Then you divide by 35 on both sides to get X by itself
35x=70
35 35
The 35's cancel out leaving X by itself
70 divided by 35=2
x=2 is the final answer
Step-by-s35tep explanation:
55+(-72)-(-45)=x
what is x?
Answer: x=28
Step-by-step explanation:
55−72−(−45)=x
Step 1: Simplify both sides of the equation.
55−72−(−45)=x
55+−72+45=x
(55+−72+45)=x(Combine Like Terms)
28=x
28=x
Step 2: Flip the equation.
x=28

Find the x−and y−intercepts of −2x − 12y = 24.
Will give Brainliest!
Answer:
X= -12 -6y, Y= -2- x/6
Step-by-step explanation:
For x
-2x-12y=24
-2x/-2 -12y/-2. 24/-2. Divide all by -2
X+6y=-12 this is what you get after
-6y. -6y. Subtract from both sides
X=-12-6y this is what you get
Find y
-2x-12y=24
-2/-2. -12/-2. 24/-2
X -6y=-12
-x. -x
-6y=-12-x
-6y/-6. -12/-6. -x/-6
Y = -2 - x/6

Juan's Work. 4 b = 2.36. A number line going from 0.51 to 0.59. A point is at 0.59.
Daviana's Work. B minus 4 = 2.36. A number line going from 6.31 to 6.39. A point is at 6.36.
Answer:
B i think
Step-by-step explanation:
Juans work is correct because the equation to find cost of each banana is 4b=$2.36
What is Number system?A number system is defined as a system of writing to express numbers.
Given that the cost of 4 bananas is $2.36
We have to find the cost of each banana.
To find this we have to divide the cost by number of bananas
Divide two point three six by four
Banana is denoted by b
4b=$2.36 is the required equation
Cost of each banana =$2.36/4
=$0.59
Hence, Juans work is correct because the equation to find cost of each banana is 4b=$2.36
