To 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:
86
Step-by-step explanation:
36 + 4 = 40 x 2 =80
36 x 2 = 82 = 4 - 86
Hope it helps!
The special number was supposed to be; 76
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
For age 'a', the special number was
2a +4
Tammi's mother actually calculated it as;
2(a +4) = 2a +8
Now 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.

With a knowledge of strings and numbers, you can announce equations to the user. Create a file that includes four different equations created with JavaScript. Each equation should be displayed to the user through JavaScript (an alert, HTML output, etc). The left side of the equation and the equal sign should be in a string, and the answer should be the actual calculation. Do not type in the answer as part of the string.
Hint: When you concatenate these two data types, place the calculation inside parentheses. Concatenating a string and a number will coerce your number into becoming a string, so you’ll want the calculation to be executed before that happens.
When you are finished, make sure your files are up and working on your Neocities account. Submit your URL to your teacher to complete the assignment. Be sure your site functions live on Neocities and contains all of the assignment's requirements. Your assignment will be graded based on the rubric below.

8 + 4f = 3f solve for f
Answer:
[tex]f=-8[/tex]
Step-by-step explanation:
[tex]8+4f=3f[/tex]
[tex]8+4f-4f=3f-4f[/tex] (Subtract [tex]4f[/tex] from both sides of the equation to isolate [tex]f[/tex])
[tex]8=-f[/tex] (Simplify)
[tex]-f=8[/tex] (Symmetric Property of Equality)
[tex]\frac{-f}{-1} =\frac{8}{-1}[/tex] (Divide both sides of the equation by [tex]-1[/tex] to get rid of [tex]f[/tex]'s coefficient; remember that [tex]-f=-1*f[/tex], so [tex]-f[/tex] has a coefficient of [tex]-1[/tex])

What is the least common multiple of 8, 2, 3a, 6b, and 4ab?
Answer:
24ab
Step-by-step explanation:
The multiple of 8, 2, 4ab, 3a, and 6b would be all the variables multiplied together right?
Then you see that:
8 can be divided by both 2 and 4 (2 x 2 x 2)
2 is 2 x 1
4ab can be 2 x 2ab
3a is the same as 3 x a
and
6b can be 2 x 3b
Now if you find the lowest common multiples (LCM's) of each variable with another you'll get your answer.
LCM of 8, 2 and 4ab is 2 times 2 times 1 times 2ab which equals 8ab
LCM of 3a and 6b is 3a times 2 times b which equals 6ab
and the
LCM of 8ab and 6ab is 2 times 2ab times 4 times 3 which equals 24ab.
A 12 ft ladder leans against a wall so that the base of the ladder is 5 ft from the wall How high, to the nearest foot, up on the wall will the ladder reach?
Answer: 10.9, about 11 ft
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + (5)^2 = (12)^2
Answer:
The ladder is the hypotenuse and one side equals 5 feet.
From the Pythagorean Theorem we can calculate the other side:
other side^2 = 12^2 -5^2
other side^2 = 144 -25
other side^2 = 119
other side = 10.9087121146
Rounding, we get 11 feet.

Antonio uses a function to determine the height of a football from the time is kicked to the time it lands on the ground. Is the function linear or nonlinear? Use words, numbers, or models to justify your answer.
Answer:
Non-linear
Step-by-step explanation:
Here, we want to determine the function type that would model the height of a football from the time it was kicked to the time it lands on the ground
The way to go about this is to notice the kind of shape or trajectory the kicked football will take.
The shape it will take is non-linear. The shape it will take would be a parabolic curve. These parabolic curve models a quadratic equation and not a linear function. Hence we can conclude that based on the kind of path in which the ball traces, we can conclude that the function that results from its trajectory would not be a linear kind of equation or representation.

There is $500 in Holly's bank account. She takes out $50 from her account each month but doesn't put money back in. What is the slope/rate? *
Answer:
The rate of change or slope m = -50
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptGiven that there is $500 in Holly's bank account.
Thus, the y-intercept b = 500
It is stated that she takes out $50 from her account each month but doesn't put money back in.
It means the rate of change or slope is decreasing.
Thus, the rate of change or slope m = -50
EXTRA BONUS!
We can also determine the line equation by substituting m = -50 and b = 500 in the slope-intercept form
[tex]y = mx+b[/tex]
y = -50x + 500
Here:
The slope m = -50
The y-intercept = 500

6th grade students were asked what their favorite subject was. 56 students said that math was their favorite subject. If there are 160 6th grade students, what is the percentage of students who chose math as their favorite subject?
Answer: 35%
Step-by-step explanation:
Given: total students in 6th grade = 160
Students said that math was their favorite subject = 56
The percentage of students who chose math as their favorite subject =
[tex]\dfrac{\text{Students like math}}{\text{Total students}}\times100[/tex]
[tex]=\dfrac{56}{160}\times100\\\\=35\%[/tex]
Hence, the percentage of students who chose math as their favorite subject = 35%.

Because the lines are parallel and segment CB crosses both lines, we can consider segment CB a transversal of the parallel lines. Angles CED and CBA are corresponding angles of transversal CB and are therefore congruent, so ∠CED ≅ ∠CBA. We can state ∠C ≅ ∠C using the reflexive property. Therefore, △ACB ~ △DCE by the

The triangles △ACB ~ △DCE are similar by AA similarity theorem.
What is AA similarity theorem?If any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other.
Given Triangle ABC with Line DE drawn inside the triangle and parallel to side AB. The line DE forms a new triangle DCE.
Because AB∥DE and segment CB crosses both lines, we can consider segment CB a transversal of the parallel lines.
Angles CED and CBA are corresponding angles of transversal CB and are therefore congruent, so ∠CED ≅ ∠CBA.
We can state ∠C ≅ ∠C using the reflexive property.
Therefore, △ACB ~ △DCE by the AA similarity theorem.
