2(a-c)=4a solve for a
Answers
Answer:
Here you go :)
So, you can't really answer this, but you can simplify it.
Simplifying
2(a + -1c) = 4a
(a * 2 + -1c * 2) = 4a
(2a + -2c) = 4a
Solving
2a + -2c = 4a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-4a' to each side of the equation.
2a + -4a + -2c = 4a + -4a
Combine like terms: 2a + -4a = -2a
-2a + -2c = 4a + -4a
Combine like terms: 4a + -4a = 0
-2a + -2c = 0
Add '2c' to each side of the equation.
-2a + -2c + 2c = 0 + 2c
Combine like terms: -2c + 2c = 0
-2a + 0 = 0 + 2c
-2a = 0 + 2c
Remove the zero:
-2a = 2c
Divide each side by '-2'.
a = -1c
Simplifying
a = -1c

someone help me and explain this is really confusing me plzz I'll brainlist u !:)
Answers
Answer:
Ok so 25$ for an adult. there are x adults so x times 25 is equals to $25x
13 dollars per child and y children so $13y
$20 for each pensioner and p pensioners so $20p
when adding these notice that none of the variable(latters) are the same so n adding will take place leaving the answer
$25x + $13y + $20p
a) $25x
b) $13y
c) $20p
d) $25x + $13y + $20p
Answer:
a) $25x, this is because if there are x number of adults coming, and $25 is the per adult charge, then irrespective of the number of adults coming this will be the equation. Eg : x = 5 So, $25 * 5 = $125
b) $13y, this is because if there are y number of children coming, and $13 is the per child charge, then irrespective of the number of children coming this will be the equation. Eg : y = 4 So, $13 * 4 = $52
c) $20p , this is because if there are x number of pensioners coming, and $20 is the per pensioner charge, then irrespective of the number of pensioner coming this will be the equation. Eg : p = 2 So, $20 * 2 = $40
d) so, the total will be, = $25x + $13y + $20p

If f = {(0,2), (2,6), (3,15),(4,9)} and g = {(3,4), (2,1),(4,6), (5,9)},
what is (f x g)(3)?
Answers
Considering the given relations, the value of the multiplication of f(x) and g(x) at x = 3 is given by:
(f x g)(3) = 60.
What is the multiplication of f(x) and g(x) at x = 3?The multiplication is given by the multiplication of each of the numeric values at x = 3, hence:
(f x g)(3) = f(3) x g(3).
The values are found as follows:
The first relation has point (3,15), hence f(3) = 15.The second relation has point (3,4), hence g(3) = 4.Hence the multiplication is given by:
(f x g)(3) = f(3) x g(3) = 15 x 4 = 60.

Maria is ordering trophies for school. Company Christopher charges $3.50 for each trophy and a one-time engraving fee of $25. Company Asya charges $7.50 for each trophy and a one-time engraving fee of $17 Develop an equation where the two companies would be the same.
Answers
Answer:
An equation where the two companies would be the same is given as:
25 + 3.50x = 17 + 7.50x
Step-by-step explanation:
Let the number of trophies ordered be represented by x
Maria is ordering trophies for school. Company Christopher charges $3.50 for each trophy and a one-time engraving fee of $25.
$25 + $3.50 × x
25 + 3.50x
Company Asya charges $7.50 for each trophy and a one-time engraving fee of $17
$17 + $7.50× x
17 + 7.50x
An equation where the two companies would be the same is given as:
Company Christopher = Company Asya
25 + 3.50x = 17 + 7.50x
Simplifying further:
Collect like terms
25 - 17 = 7.50x - 3.50x
8 = 4.00x
x = 8/4
x = 4
Hence, the two companies would be the same after 4 trophies.
A triangle has sides equal to 3, 4, and 5.
Which statement regarding the triangle is correct?
A. The triangle is an equilateral triangle.
B. The triangle is an isosceles triangle.
C. The triangle is an obtuse triangle.
D. The triangle is a right triangle
Answers
Answer:
D
Step-by-step explanation:3,4,5 is a pythagorean triple, making it a right triangle
Answer:
D
Step-by-step explanation:
If you use the Pathagorean theorum where [tex]A^{2}[/tex] + [tex]B^{2}[/tex] = [tex]C^{2}[/tex] and plug in the number you were given, you get [tex]3^{2}[/tex] + [tex]4^{2}[/tex] = [tex]5^{2}[/tex] or 9 + 16 = 25 which is correct.
So this has to be a right triangle.
You can also eliminate answer A because you already know none of the sides are equal so it can't be equilateral.
You can eliminate answer B because you already know that no two sides have an equal length so it can't be defined as isosceles.
You can eliminate answer C because if it were obtuse, the 3rd side (5) would have to be a lot longer.

Please help me find all 3 !
Answers
Answer:
m<P = 60 degrees
Step-by-step explanation:
All sides of the triangle are equivalent to each other.
All three sides of the triangle equal 180 degrees total.
Since there are 3 sides, we divide 180 by 3 to find the measurement for all sides
180 ÷ 3 = 60
Q = 60 degrees
P = 60 degrees
R = 60 degrees
Check your work by adding all three sides together to equal 180:
60 + 60 + 60 = 180
180 = 180
Work is correct
