Solve the proportion. I need to show much work so a step by step explanation would help!
Answer:
Solution: x=5
Step-by-step explanation:
Equations
This is an equation in the form of a proportion or ratio:
[tex]\displaystyle \frac{2}{x+3}=\frac{5}{4x}[/tex]
To solve it, we eliminate the denominators by multiplying by both of them.
Multiply by (x+3)(4x):
[tex]\displaystyle (x+3)(4x)\frac{2}{x+3}=(x+3)(4x)\frac{5}{4x}[/tex]
Simplify both sides:
[tex](4x)*2=(x+3)*5[/tex]
Operate:
[tex]8x=5x+15[/tex]
Simplify:
[tex]3x=15[/tex]
Solve for x:
[tex]x=15/3=5[/tex]
Solution: x=5

#2) A 12-ounce bag of marbles contains 64 marbles. Assume the relationship between weight and number of marbles is proportional. How much would you expect a bag of 160 marbles to weight (in ounces)? *
Answer:
Step-by-step explanation:
a 12 ounce bag = 64 marbles
So first you want to find out how much each marble weighs. To do this divide 12 ounces by 64.
1 marble = [tex]\frac{12}{64} = \frac{3}{16} ounces[/tex]
To find the weight of 160 marbles, you just multiply the weight of 1 marble by 160.
160 marbles = [tex]\frac{3}{16}[/tex] ×[tex]160[/tex] = 30 ounces.
What is the slope of the line that passes through the points M (-3,5) and N (1,8)
Answer:
m=3/4
Step-by-step explanation:
See the attached above.
Hope it helps :)
The slope of line passing through M (-3,5) & N (1,8) will be 3/4.
We have been given a line passing through points M (-3,5) & N (1,8) .
We have to find out what will be the slope of the line ?
What is the formula for slope of a line ?
Slope of line is given by , m = (y2-y1) / (x2-x1).
Given that line is passing through points M (x1 , y1) and N (x2,y2) or M (-3,5) & N (1,8).
here , x1 = -3 , y1 = 5 , x2= 1 . y2 = 8
The slope (m) of line will be ;
∵ m = ( y2-y1) / (x2-x1)
m = ( 8-5) / (1- (-3))
m = 3 / 4

then y= 32. What is the value of x when y= 176?
Answer: Wouldn't that make it x=44
Step-by-step explanation:
I just divided 176 by 4 because it said the value of y varies directly with x. So just used the rule they used i guess.

Step-by-step explanation:
Answer:
10
Step-by-step explanation:
Kinsey is 7 years less than twice Jacob's age. Let's call Jacob's age x. IF we call Jacob's age x, our equation can be 2x-7 = 13
2x - 7 = 13
2x = 20
x=10

x^2+6x≤-5 with an explanation pls
Answer:
−5≤x≤−1
Step-by-step explanation:hope that helps :)))
x2+6x=−5
x2+6x−(−5)=−5−(−5)(Subtract -5 from both sides)
x2+6x+5=0
(x+1)(x+5)=0(Factor left side of the equation)
x+1=0 or x+5=0(Set factors equal to 0)

What is the value of s?
Answer:
s = 3.5
Step-by-step explanation:
Lets begin by distributing -8 into the two values in the paranthesis, s and +4. By doing this, we get -8s -32 = -60
We can now take that -32 and bring it to the right side of the equation, making it now -8s = +32 -60
After simplyfing, we now have -8s = -28. Dividing -28 by -8 , we get positive 3.5.
