Answer:
x = 7
Step-by-step explanation:
Step 1: Add 6 to both sides.
[tex]3x - 6 + 6 = 15 + 6[/tex] [tex]3x = 21[/tex]Step 2: Divide both sides by 3.
[tex]\frac{3x}{3} = \frac{21}{3}[/tex] [tex]x = 7[/tex]Step 3: Plug in the value to see if it's correct.
[tex]3(7) - 6 = 15[/tex] [tex]21 - 6 = 15[/tex] [tex]15 = 15[/tex]Therefore, x = 7.

What value of x makes the equation -5x - (-7 - 4x) = -2(3x - 4) tru
Answer: 1/10 or 0.1
Step-by-step explanation:
-(-7 - 4x) = -2(3x - 4)
7 + 4x = -6x + 8
* subtract 7 from both sides
4x = -6x + 1
* Add 6x to both sides
10 x = 1
* Divide both sides by 10
x = 1/10 or 0.10

Least to greatest 3%,00.8,2/50
Answer:
3% , 2/50 , 0.08
Step-by-step explanation:
I believe the easiest way to go about this is to convert all the numbers t0o decimals!
0.08 is already given, so we just need to figure out what 3% and 2/50 are in decimal form.
When converting percents to decimals, a good rule of thumb to remember is to divide the percent by 100.
3 ÷ 100 = 0.03
For fractions, simply divide the numerator by the denominator:
2 ÷ 50 = 0.04
Now we just order the numbers based on their value...
0.03, 0.04, 0.08
So the final answer should be:
3% , 2/50 , 0.08

What is the slope-intercept form of (-12,-6) (8,9)
Answer:y=3/20+12m+6
Step-by-step explanation: The equation for these types of problems are y=mx+b
the y is the second number, so in the first one the y would be -6, so you replace the y with the -6 and the x with -12
so now the equation is -6=-12m+b
you add the -12m to the other side to make 12m+6=b
now onto the second one, the 9 is the y and the 8 is the x, now the equation is 9=8m+b
this time you replace the b with the equation you got earlier (12m+6=b)
So the equation is 9=8m+12m+6
minus the 6 on both sides
3=8m+12m
add the m's
3=20m
3/20=m
Now you replace the m and the b
y=3/20x+12m+6
(Hopefully im sorry if this isnint correct :) )

Aiden buys ice cream and apples at the store.
He pays a total of $15.05.
• He pays a total of $3.80 for the ice cream.
• He buys 3 bags of apples that each cost the same amount.
Write and solve an equation which can be used to determine x, how much each bag
of apples costs.
Answer:
Equation: y = 3x + 3.80
Cost of each bag: $3.75
Step-by-step explanation:
y = 3x + b
y = $15.05
x = cost of each bag
b = $3.80
3 = # of bags
15.05 = 3x + 3.80
11.25 = 3x
3.75 = x
The equation to determine x is y = 3x + 3.8
and cost of each apple bag is $3.75.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
Total amount paid by Aiden = $15.05
Total amount paid for ice cream = $3.80
Number of bags of apple = 3
So if x is the amount of each apple bag and y is the total amount paid by Aiden,
So,Cost of apple bags = 3x
And total amount = 3x + 3.8
or y = 3x + 3.8
this is the equation to determine x.
Now since, total amount paid is $15.05
⇒ 15.05 = 3x + 3.8
or,3x = 15.05 - 3.8
or 3x = 11.25
⇒ x = 11.25/3
⇒ x = $3.75
Thus,the equation to determine x is y = 3x + 3.8
and cost of each apple bag is $3.75.

Georg travels 60 miles in one hour. How many miles will he drive in 4 hours?
Answer: The answer is: " 240 mi. " .
_______
Step-by-step explanation:
To solve using a technique known as "dimensional analysis":
_______
→ " [tex]\frac{60 mi}{1 hr} * \frac{4hr}{1} =[/tex] ? mi
→ On the "left-hand side" of the equation; the units of "hr" ["hour(s)"] "cancel out"; since: "hr/hr = 1 " ;
→ and we are left with: " (60 mi * 4 )" = " 240 mi ".

if the breadth of rectangle in one fourth of its length and perimeter is 60 cm ,find the length and breadth of rectangle
Answer:
Breadth/width = 1.936cm, length = 7.746cm
Step-by-step explanation:
Perimeter of a rectangle would be [tex]2L*2W=60cm[/tex] in this case. Breadth is width.
But we can rewrite this equation given that the width is 1/4 the length. This means 4 of the widths would equal one length.
[tex]W=\frac{1}{4}L[/tex]
[tex]L=4W[/tex]
We can substitute L with the 4W
[tex]2(4W)*2(W)=60cm[/tex]
Now we can just solve for the width W.
[tex]8W*2W=60\\16W^2=60\\W^2=\frac{15}{4} \\W=\sqrt{\frac{15}{4} } \\W=\frac{\sqrt{15} }{2}=1.936cm[/tex]
We now know the width is about 1.936cm
We can find the length given our formula before of [tex]L=4W[/tex]
[tex]L=4(\sqrt{\frac{15}{2} } )=2\sqrt{15} =7.746cm[/tex]
So the breadth/width is 1.936cm and the length is 7.746cm.

Answer:
65
Step-by-step explanation:
45, 50, 52, 58, 62, 68, 72, 78, 81, 95
62 + 68 = 130/2 = 65
The median is 65
The median of the weight of the male dogs is M = 65 lb
What is Median?The median is the value that's exactly in the middle of a data set when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values. The steps for finding the median differ depending on whether you have an odd or an even number of data points
Arrange the data points from smallest to largest.
If the number of data points is odd, the median is the middle data point in the list.
If the number of data points is even, the median is the average of the two middle data points in the list.
Given data ,
Let the weights of the male dogs be represented as set A
where the value of A is
Set A = { 45, 50, 52, 58, 62, 68, 72, 78, 81, 95 }
On simplifying , we get
The number of terms = 10
So , the median M = ( 62 + 68 ) / 2
The median M = 130/2 = 65 lb
where the mean is C = 66.1 lb
Hence , the median is M = 65 lb
