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])
[tex]f=-8[/tex] (Simplify)

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%.

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.

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.

AB is parallel to CD
Find the value of X
Find the value of Y
Answer:
∠y° = ∠69°
∠x = ∠69°
Step-by-step explanation:
1) The question relates to parallel line theorem
The given parameters are;
AB is parallel to CD
∠111° and ∠y° are consecutive interior angles
∠69° and ∠x° are alternate interior angles
When two parallel lines are crossed by a common transversal, the consecutive interior angles are supplementary (sum up to 180°), and the alternate interior angles are equal
Therefore, we have;
∠111° + ∠y° = 180°
∠y° = 180° - ∠111° = ∠69°
∠y° = ∠69°
2) For the alternate interior angles, ∠69° and ∠x°, we have;
Alternate angles are equal, therefore ∠x = ∠69°
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.

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.

The mean of 5 numbers is 6.
The numbers are in the ratio 1 : 3 : 3 : 4 : 4.
Find the numbers.
Answer:
2, 6, 6, 8, 8
Step-by-step explanation:
First, we know that the mean is the sum of the number divided by the amount, so if we take the answer we have, 6, and multiply that by the amount of number, 5, then we get 30.
Now we add the numbers in the ratio, so 1 + 3 + 3 + 4 + 4 = 15
15 x 2 = 30
This means we need multiply the numbers in the ratio by 2 to get
2 + 6 + 6 + 8 + 8 = 30
Answer:
2, 6, 6, 8, 8
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex], thus
[tex]\frac{sum}{5}[/tex] = 6 ( multiply both sides by 5 )
sum = 30
sum the parts of the ratio, 1 + 3 + 3 + 4 + 4 = 15 parts
30 ÷ 15 = 2 ← value of 1 part of the ratio, thus
3 parts = 3 × 2 = 6
4 parts = 4 × 2 = 8
Thus the 5 numbers are
2, 6, 6, 8, 8

C.The slope from point O to point A is fraction 1 over 2 time the slope of the line from point A to point B.
D.The slope from point O to point A is two times the slope of the line from point A to point B.
Answer:
A
Step-by-step explanation:
You can use the formula change in y divided by change in x, so for this the change in y would be 2 and the change in x would be 4. This means the slope is 1/2.
In a line, the slope never changes so it's A.

Answer and Step-by-step explanation:
To solve, you first divide 7 by 9.
Then, you divide 119 by 7/9.
[tex]\frac{7}{9} = 0.777777777777\\\\\frac{119}{0.77777777777} = 153.\\\\[/tex]
To check your work, divide 119 by 153, and you will get 0.777777777777, which is the same as 7 divided by 9.
