o figure out a special number, Tammi’s mother was supposed to double her age and then add 4. Instead, Tammi’s mother added 4 to her age and then doubled that number. Tammi’s mother thought the special number was 80. What was the special number supposed to be?
Answer:
40
her age was 36 she added 4nwhich made 40 then doubles makesn80
9514 1404 393
Answer:
76
Step-by-step explanation:
For age 'a', the special number was supposed to be ...
2a +4
Tammi's mother actually calculated it as ...
2(a +4) = 2a +8
a value that is (2a+8) -(2a+4) = 4 more than it was supposed to be.
The special number was supposed to be 80 -4 = 76.
Write down the integer values of x that satisfy the inequality -2 < x _<4
Those integers are {-1,0,1,2,3,4} (integers in the range -2 and 4)
The integer values of x that satisfy the given inequality are {-2, -1, 0, 1, 2, 3, 4}.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is -2<x≤4.
The integer values of x that satisfy the inequality are
{-2, -1, 0, 1, 2, 3, 4}
Therefore, the integer values of x that satisfy the given inequality are {-2, -1, 0, 1, 2, 3, 4}.

Answer:
∠Z = 34°
∠T = 56°
Step-by-step explanation:
You can solve for x using the measure of the right angle:
90 = 3x +6
30 = x +2 . . . . . divide by 3
28 = x . . . . . . . . subtract 2
Then the measure of T is ...
∠T = 2x° = 2(28)° = 56°
∠Z is its complement: 90° -56° = 34°
The angle measures are ...
m∠Z = 34°
m∠T = 56°

Answer:
4). [tex]-\frac{27}{28}[/tex]
5). Amount payable by the customer = 1416 Rs.
Step-by-step explanation:
4). [tex](\frac{3}{7})\times (-\frac{5}{8})\div (\frac{1}{3}\times \frac{5}{6})[/tex]
= [tex](-\frac{15}{56})\div (\frac{5}{18})[/tex]
= [tex](-\frac{15}{56})\times \frac{18}{5}[/tex]
= [tex]-\frac{54}{56}[/tex]
= [tex]-\frac{27}{28}[/tex]
5). Cost of the item = Rs 1200
G.S.T. applicable on this item = 18%
Amount to be paid for G.S.T.= 1200 × [tex]\frac{18}{100}[/tex]
= Rs 216
Total amount payable by the customer = Cost + G.S.T.
= 1200 + 216
= Rs 1416

6x+5-4y-2x+y=
PLEASE HELP ME I NEED IT ASAPPPPPPPP!!!!!!!!!!!!!!!!!!!!!!!
Answer:
There is no way to solve this for x or y, as only one relationship between those variables is provided. We can, however simplify that expression.
6x + 5 - 4y - 2x + y
group like terms:
= 6x - 2x - 4y + y + 5
add like terms together
= 4x -3y + 5
And that is as much as can be done with just that expression.
The simplest form of the given equation 6x+5-4y-2x+y is 4x - 3y + 5.
What is simplification?A mathematical expression is simplified when it is replaced with a simpler, typically shorter, equivalent statement. Simplifying procedures is one way to achieve uniformity in work efforts, expenses, and time. It reduces diversity and variety that is pointless, harmful, or unnecessary.
Given an expression 6x+5-4y-2x+y
simplifying it
=> 6x -2x -4y + y +5
(adding terms with same variable)
=> 4x - 3y + 5.
therefore, the simplest form of the given equation is 4x - 3y + 5.

#SPJ2
While attempting to multiply the expression (2-5i)(5+2i) a student made a mistake.
(2-5i)(5+2i)= 10+4i -25i - 10i^2
=10+4(-1)-25(-1) - 10(1)
=10-4+25-10
=21
What is the error?
Answer:
The left side of the equation is ignored
i is treated as -1, which it is not, it is instead the square root of negative 1.
To solve it properly we get:
(2 - 5i)(5 + 2i)
= 10 + 4i - 25i - 10i²
= 10 + 21i + 10
= 20 - 21i
Answer:
The error is that, the student replaced i with -1 which is wrong as i = √-1
And he has replaced i^2 with 1 while i^2 = -1
Step-by-step explanation:
Given two numbers that are being multiplied are:
(2-5i)(5+2i)
We will solve the question to get the right result so that the error can be detected.
So, multiplying both
[tex]= 2(5+2i)-5i(5+2i)\\=10+4i-25i-10i^2\\=10-21i-10(-1)\ \ \ as\ i^2 = -1\\=10-21i+10[/tex]
The error is that, the student replaced i with -1 which is wrong as i = √-1
And he has replaced i^2 with 1 while i^2 = -1

Find each function value f(-4) if f(x) = -5x - 3
Answer: f(-4) = 17
Step-by-step explanation: Substitute (-4) for x.
f(-4) = -5(-4) - 3f(-4) = 20 - 3f(-4) = 17Can anybody answer this question??
The answer is A
as the x+ 4 is when we replace x with 0
x=0
so
y=0+4
=4
So the line of y must intersect at (0,4) coordinate
which is given as in A and should be a positive slope

Answer:
The interest is: $2550.00
Step-by-step explanation:
I = P x r x t
P is the principal amount, $12000.00.
r is the interest rate, 4.25% per year, or in decimal form, 4.25/100=0.0425.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 12000 × 0.0425 × 5 to get that:
The interest is: $2550.00

Answer:
Volume = 1436.8 cm³
Step-by-step explanation:
Formula for the volume of a sphere = [tex]\frac{4}{3}\pi r^{3}[/tex]
Here, r = radius of the sphere
For a sphere which has the radius = 7 cm
Volume of the sphere = [tex]\frac{4}{3}\pi (7)^3[/tex]
= 1436.76
≈ 1436.8 cm³
Therefore, volume of the sphere is 1436.8 cm³.

Answer:
From looking at the graph, we can already tell it's a negative slope because it's tilting down, so we can eliminate A and D. Where the line intersects the y-axis is the y-intercept or b. Since it intersects at (0,2), the equation should be y=-2x+2.

60 minutes is 20% of
minutes.
Answer:
60 minutes is 20% of 300 minutes
Step-by-step explanation:
let x be the number of total minutes
60 = 20% of x
20% = 1/5
60 = 1/5x
multiply both sides by 5
300 = x
x = 300 minutes
