Tessa bought stock in a restaurant for $277.00. Her stock is now worth $346.25. What is the percentage increase of the value of Tessa's stock?
Answer:
125%
Step-by-step explanation:
Divide 346.25 by 277
you get 1.25
multiply it by 100
Answer:
25%
Step-by-step explanation:
This is calculated this way:
$346.25/$277 = 1.25
Then subtract 1, because that part represents what Tessa had to start with. That leaves
0.25
That decimal equals 25%, and that is the answer.

Step-by-step explanation:
can you help me please
Answer:
-20, probably.
Step-by-step explanation:
This is worded weirdly I assume it means there is a slope of one. Also, I hate that you got the points for this question by putting nonsense "answers" on questions, but you seemed like a halfway decent person.

X = 25 -3y and 4x + 5y = 9
What are the solutions
Answer:
x=-14, y=13
Step-by-step explanation:
4x+5y=9
x+3y=25
4x+5y=9
-4x-12y=-100
-7y=-91
y=13
Subsitute: x+3(13)=25

Rewrite as a simplified fraction. \large{0.\overline{23} = {?}}0. 23
Answer:
23/100
Step-by-step explanation:
Given the decimal value 0.23, to write as a fraction;
0.23 = 23/100
The place value of dot will be replaced as 1 at the denominator and since the decimal is in 2 decimal places, two zeros will be added to after the 1 to make it 10 thereby making the required fraction 23/100. Hence the value of 0.23 as a fraction will be 23/100

Step-by-step explanation:

I need the solution. Please give steps
y = 10x + 20
y = 20x + 10
Answer:
If your trying to answer for X, here is how you do it.
For the equation '' Y = 10x + 20 '', isolate the variable 'X' by dividing each side by factors that don't contain the variable 'X', to get your answer:
X = Y/10 − 2
Or
X = [tex]\frac{Y}{10}[/tex] − 2
For the other equation " Y = 20x + 10 ", it's the exact same thing. Isolate the variable 'X' by dividing each side by factors that don't contain the variable 'X', to get your answer:
X = Y/20 − 1/2
Or
X = [tex]\frac{Y}{20}[/tex] − [tex]\frac{1}{2}[/tex]
Id.k uhhhh
X = 30?

Paul invests £150 in a bank account paying 2% interest per annum for 10 years. Work out how much money he has in the account at the end of the 10 years
Answer: £180
Step-by-step explanation:
The interest gotten for the 10 years will be calculated as:
= Principal × Rate × Time
= 150 × 2% × 10
= 150 × 0.02 × 10
= 30
The amount he has in the bank account at the end of the 10 year will be:
= Principal + Interest
= £150 + £30
= £180
The mean average of 4 numbers is 88 what is the fourth number if three of the numbers are 80 95 and 85?
Answer:the fourth number is =97
Step-by-step explanation:
Mean = total number of the given numbers( x1 +x2+ x3....) / numbers given
Let the fourth number be x
given that the mean of 4 numbers = 88 and only 3 numbers are given
such that
Mean = total number of the given numbers( x1 +x2+ x3....) / numbers given becomes
88= (80 +90 + 85 + x ) / 4
88 x 4 =80 +90 + 85 + x
352=255+x
x= 352-255
x=97

Four chords are drawn in the figure below, creating a quadrilateral with every vertex on the circle.
Using the special properties of this figure, determine m
Answer:
21°
Step-by-step explanation:
<DCB = 3x + 8°
< DAB = 5x + 4°
Now
<DCB + <DAB = 180° { being opposite angles of cyclic quadrilateral }
3x + 8° + 5x + 4° = 180°
8x + 12° = 180°
8x = 180° - 12°
8x = 168°
x = 168° / 8
Therefore x = 21°
Hope it will help :)
(PLEASE HELP)Solve the given system using your choice of either graphically or algebraically. Show and explain all work.
y = 2x - 4
x + 2y = 12
Answer:
algebraically.
y = 2x - 4........….....(1)
x + 2y = 12..............(2)
substituting the value of y in equation (2) we get
x+2(2x - 4)=12
x+4x-8=12
5x=12+8
x=20/5=4
substituting the value of x in equation(1) we get
y=2×4-4=8-4=4
:.(x,y)=(4,4)answer
The value of x = 4
The value of y = 4
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first equation be = A
Let the second equation be = B
Now ,
y = 2x -4
Subtracting 2x on both sides , we get
y - 2x = -4 be equation (1)
And ,
x + 2y = 12 be equation (2)
Now , on simplifying the two equations , we get
Multiply equation (1) by 2 , we get
2y - 4x = -8 be equation (3)
Now , subtract equation (3) from equation (2) , we get
5x = 20
Divide by 5 on both sides , we get
x = 4
Therefore , the value of x is 4
Substitute the value of x in equation (2) , we get
4 + 2y = 12
Subtracting 4 on both sides , we get
2y = 8
Divide by 2 on both sides , we get
y = 4
Therefore , the value of y is 4
Hence , The value of x and y is 4

what is the equation for y=(1/4)^x+1
Answer:
A:(1,-3/4)
Step-by-step explanation:
Use substitution to solve the system
y= 1/4x-1
y= -1/2x-1/4
1/4x-1 = -1/2x-1/4, Solve for x
3/4x= 3/4, x = 1, Next solve for y by plugging the x-value into either equation.
y=1/4(1)-1
y=-3/4

Please help ASAP Which equation represents the function graphed
on the
coordinate plane?
Answer:
g(x) = |x + 4| - 2
I recommend next time you try substituting the x-values from points the line meets into each function until g(x) matches the y-value. For example, the line/function passes through the point (1, 3). Substitute the x-value: 1 into the function where it says x. That would give you 3 = |1 + 4| - 2. (If you're wondering where I got 3 from g(x) is basically the same as y. Simplify the values in the "||" first. You should then get 3 = 5 - 2. Simplify that and you get 3 = 3 which means g(x) = |x + 4| - 2 is the correct answer. If you were to get anything else other than 3 such as "3 = 4", it would not be correct.
