2y=100
y=50
x=54
seven more than twice a number is greater than negative fifteen
Answer: 2n > -15
Step-by-step explanation:
We can use the variable n to show the unknown number.
It says that there is twice a number, meaning two of an unknown number. We can show it by using the term 2n.
It also states that 2n is greater than -15. Because of that, we can use the equation 2n > -15, to show that 2n is greater than -15.
(Quick note: The variable n just represents the unknown number, you can subsitutue any variable into its place.)
The Inequality that shows seven more than twice a number is greater than negative fifteen is; 2n > -15
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
We can consider the variable n to show the unknown number.
That says, there is twice a number, meaning two of an unknown number. We can show it by using the term "2n".
It states that seven more than twice a number is greater than negative fifteen
MEans 2n is greater than -15.
we can use the equation 2n > -15, to show that 2n is greater than -15.

Solve the system of equations using substitution.
y = -7x
2x - y = -9
Step-by-step explanation:
Since y= -7x you will want to substitute the y in the other equation.
2x -(-7x) = -9
2x + 7x = -9
9x = -9
so x will be -1
y= -7(-1)
x= -1
y= 7
Answer:
x = -1 , y =7 (-1,7)
Step-by-step explanation:
[tex]y=-7x\\2x-y = -9\\[/tex]
[tex]2x+7x = -9[/tex]
[tex]2x+7x = 9x\\[/tex]
[tex]9x = -9\\[/tex]
[tex]\frac{9x}{9} =\frac{-9}{9}[/tex]
[tex]x = -1\\[/tex]

Given :
segment AB = segment ADsegment BC = segment DC∠B =∠Dsegment AC bisects ∠BADThis means that △ABC≅△ADC under the SAS congruence criterion because according to this criterion if two sides and one included angle is equal two triangles are congruent and since these two triangles fulfill these rules they are said to be congruent under the SAS congruence criterion. But they are also congruent under the ASA congruence criterion which states that if two angles and one included side is equal two triangles are congruent. Since △ABC and △ADC fulfill these rules too they can said to be congruent under the ASA congruence criterion.

Sequence find the 82nd term
Answer:
1385
Step-by-step explanation:
1) the difference is d=25-8=42-25=17;
the sequence given in the condition is arithmetic one (linear relationship).
2) in order to calculate the value of the 82d term:
a(n)=a(1)+d*(n-1), where n - number of required term (it is 82), then
a(82)=8+17*(82-1)=8+1377=1385.

your family went out to dinner to celebrate your grandmas 100th birthday. The total for the dinner was $208.60, so your parents left a $31.29 tip. What percent of the bill was the tip?
Answer:
[tex]\%Tip = 13.04\%[/tex]
Step-by-step explanation:
Given
[tex]Tip= \$31.29[/tex]
[tex]Bill = \$208.60[/tex]
Required
Determine the percentage of the tip
First, we calculate the amount paid
[tex]Amount = Tip + Bill[/tex]
[tex]Amount = \$31.29 + \$208.60[/tex]
[tex]Amount = \$239.89[/tex]
The percentage of the tip is then calculated using:
[tex]\%Tip = \frac{Tip}{Amount} * 100\%[/tex]
[tex]\%Tip = \frac{31.29}{239.89} * 100\%[/tex]
[tex]\%Tip = \frac{31.29* 100}{239.89} \%[/tex]
[tex]\%Tip = \frac{3129}{239.89} \%[/tex]
[tex]\%Tip = 13.04\%[/tex]

convert 10009 out of 17%
Answer:
Step-by-step explanation:
To convert 10,009 to 17%, turn 17% to decimal and multiply that by 10,009 (10,009 * 0.17), which equals 1,701.53
IF you meant to convert the fraction 10,009/17% (read as "10,009 out of 17 percent, ") then simply convert 17% to a decimal (0.17) and divide 10,009 by 0.17 (10,009/0.17) which is about 58,876.47, for full decimal, use a calculator and do 10,009/0.17
The question is kind of confusing so tell me what you meant

traveling with the current a certain boat went 24 km/h. Against the same current it only went 2 km/h. Find the current and the speed of the boat if there were no current.
Answer:
Current= 13
Speed= 11
Step-by-step explanation:
Let x represent the speed of the boat
Ley y represent the rate of current
x + y= 24......equation 1
x - y= 2...........equation 2
Using elimination method
x + y= 24
+
x - y= 2
2x = 26
x = 26/2
x = 13
Sub 13 for x in equation 1
x + y= 24
13 + y = 24
y = 24-13
y = 11
Hence the current and speed of the boat when there were no current are 11 and 13 respectively
