the sum of the digits of a two-digit number is 11 the tens digit is one less thn three times the ones didgit find the original number
Answer:
The original number is 83
Step-by-step explanation:
let the number be ab
Sum of the two is 11
a + b = 11
tens digit a is one less than 3 times the ones digit
3b - a = 1
a = 3b - 1
3b -1 + b = 11
4b = 11 + 1
4b = 12
b = 12/4
b = 3
a = 3b - 1
a = 3(3) - 1
a = 9-1
a = 8

h > 75.5
Answer:
DStep-by-step explanation:
hope it helps....... .
The value of the variable h is greater than 75.5 that means at 75.5 there will be an open circle.
What is a number line?A number line refers to a straight line in mathematics that has numbers arranged at regular intervals or portions along its width. A number line is often shown horizontally and can be postponed in any direction.
Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The inequality is given below.
h > 75.5
The value of the variable h is greater than 75.5 that means at 75.5 there will be an open circle.

Her budget is $65 a month. To find out how many gigabytes of data she could use if she chose this plan, she writes C(x)=65 and solves for x. What value of x makes this equation true?
Remember the function is C(x)=30x+5.
Answer:
Consider all the info you are given:
The monthly allowance is 2 GB...this is basically how much data is included in the the plan so that the monthly pymt is the same every month. When the GBs used goes pass 2GB...there is a cost to that.
You're given C(x) = 30x + 50, the monthly cost of the plan
'x' is the GB of data used OVER the allowance (2GB.)
They put over in italics to give you a hint to the solution.
(a) C(0.7) is the cost when the data used goes over 2GB by 0.7 GB. C(0.7) = 30(0.7) + 5 = 26
The college student would pay $26 when they use an extra 0.7GBs (pass the allowance.)
(b) This part to the problem wants you to figure out how much the overage, pass the 2GBs, the college student can go and only end up paying $50 (the set budget)
So you the solve for x by setting C(x) = 50
30x + 5 = 50
30x = 50 - 5 = 45
x = 45/30
x = 1.5
Remember x is the overage (the GBs over the allowances), so to stay at budget, the college student can use 3.5 GBs of data (2GBs + 1.5 GBs) only pay $50 that month.
Hope this helps...

Solve the inequality and enter your solution as an inequality comparing variable to solution-31>x-48
Answer:
solving the inequality [tex]-31>x-48[/tex] we get: [tex]\mathbf{x<17}[/tex]
Step-by-step explanation:
We need to solve the inequality [tex]-31>x-48[/tex]
Solving the inequality and finding value of x:
[tex]-31>x-48[/tex]
First we will be switching sides i.e. left hand side will become right hand side and right hand side will become left hand side. In doing so, the inequality sign i.e. > will be reversed and changed with <
[tex]x-48<-31[/tex]
Now, for finding value of x, we will be adding 48 on both sides
[tex]x-48+48<-31+48\\x<17[/tex]
The value of x is less than 17 i.e. [tex]\mathbf{x<17}[/tex]
So, solving the inequality [tex]-31>x-48[/tex] we get: [tex]\mathbf{x<17}[/tex]

You set up a hot chocolate stand at a football game. The cost of your supplies is $75. You charge $0.50 for each cup of hot chocolate. Write a function that represents the profit P for selling c cups of hot chocolate.
Answer:
P = 0.5c - 75
Step-by-step explanation:
Profit is = selling price. - cost price
Cost price is the amount the supplies were bought = $75
The cost of c cups at $0.5 per cup will be
0.5 * c = $0.5c
The profit here is thus;
P = 0.5c - 75

Answer:
angle 3 = 27 degrees
Step-by-step explanation:
Answer:
Angle 3 = 27

If we have six decisions to make and 2 choices for each decision, how can we represent the number of potential outcomes?
A 6 to the power of 2
B 2 to the power of 2
C 6 to the power of 6
D 2 to the power of 6
Answer:
A
Step-by-step explanation:
because for each 6 you have 2
We can represent the number of potential outcomes by 2 to the power 6.
What is permutation and combination?'In mathematics, permutation relates to the act of arranging all the members of a set into some sequence or order.
The combination is a way of selecting items from a collection, such that the order of selection does not matter.'
'The power of a number says how many times to use the number in a multiplication. Powers are also called exponents or indices.'
According to the given problem,
We can assume, for two choices, we have one decision.
This can be represented as [tex]2^{1}[/tex].
Since, we have six decisions,
Representation of the potential outcomes ⇒[tex]2^{1}+2^{1} +2^{1} +2^{1} +2^{1} +2^{1}[/tex]
= [tex]2^{6}[/tex]
= [tex]64[/tex]
Hence, the representation of the number of potential outcome is 2 to the power 6.

5. A system of equations is below. For what value would
you multiply the first equation to eliminate the x-term?
(y=x+2
3x + 3y = 6
Answer:
We would multiply the first equation by -3 to eliminate the x-term.
Step-by-step explanation:
Given the system of equations
y = x+2 Equation 1
3x+3y = 6 Equation 2
Multiply the Equation 1 by -3
-3y = -3(x+2) ⇒ -3y = -3x-6 ⇒ -3x+3y = 6
Thus, equation 1 becomes
-3x+3y = 6
Now, adding equation 2
-3x+3y = 6
+
3x+3y = 6
________
0x + 6y = 12
6y = 12
y = 2
Therefore, we would multiply the first equation by -3 to eliminate the x-term.

You are planning the running shoe merchandise levels for your shoe store. Last year, your running shoe sales were down 10% from the previous season. The store had projected sales of 900 pairs of running shoes. Calculate the number of units the 10% sales decline represents.
Answer:
90
Step-by-step explanation: by taking 10% off of 900, you get 810; meaning 90 was subtracted
The number of units the 10% sales decline represents is 90
what is percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"
Given here projected sales = 900 but the actual sales is 10% less than this amount , thus actual sales = 900 - 10% of 900
= 900 -( 10/100 )×900
= 900 - 90
= 810
Hence, the number of units the 10% sales decline represents is 900-810 =90
