Answer:
According to the question,
[tex]12x + 8x + 5x = 75[/tex]
_____________________
[tex]12x + 8x + 5x = 75[/tex]
[tex]25x = 75[/tex]
[tex]x = \frac{75}{25} [/tex]
[tex]x = 3[/tex]
Now,
[tex]12x = 36[/tex]
[tex]8x = 24[/tex]
[tex]3x = 15[/tex]
So,
75 in the ratio of 12 : 8 : 5 is
36, 24 and 15
Answer:
36 : 24 : 15
Step-by-step explanation:
sum the parts of the ratio, 12 + 8 + 5 = 25 parts
Divide the quantity by 25 to find the value of one part of the ratio
75 l ÷ 25 = 3 l , then
12 parts = 12 × 3 = 36 l
8 parts = 8 × 3 = 24 l
5 parts = 5 × 3 = 15 l

what is the answere to 7 times 4/21

[tex] \\ [/tex]
[tex] \sf 7 \times \dfrac{4}{21} [/tex]
[tex] \\ [/tex]
First, write 7 as a fraction:
[tex] \\ [/tex]
[tex] \sf 7 \times \dfrac{4}{21} = \dfrac{7}{1} \times \dfrac{4}{21} [/tex]
[tex] \\ [/tex]
Then, identify the value of a, b, c, and d:
a = 7b = 1c = 4d = 21[tex] \\ [/tex]
We can finally find our answer:
[tex] \\ [/tex]
[tex] \sf \dfrac{7}{1} \times \dfrac{4}{21} = \dfrac{7 \times 4}{1 \times 21} = \dfrac{28}{21} [/tex]
[tex] \\ [/tex]
Let's simplify our answer:
[tex] \\ [/tex]
[tex] \sf \dfrac{28}{21} = \dfrac{4 \times 7}{4 \times 7} = \boxed{\boxed{\sf \dfrac{4}{3}}} [/tex]

3x2 - 12x + 11 = x
Answer:
(13 + or - (sign) square root(37)) / 6
Step-by-step explanation:
First search up the quadratic formula which is
x = (- b + or - square root(b^2 - 4ac)) / 2a
and to find a, b, and c you need this formula
ax^2 + bx + c = 0 (btw this is the safest solution to finding your answer with a number in-front of a quadratic equation.)
Math:
a = 3, b = -13, c = 11
b = -13, because of the x on the other end of the equation as the equation above "ax^2 + bx + c = 0" you need the zero to proceed to this next step.
Side Note: You only take the number and not the variable, variables are x, y, w, z, or etc.
(- (- 13) + or - square root((-13)^2 - 4(3)(11) ) ) / 2 * 3
13 + or - square root(37) / 6

Ryan and his brother Will went to the store to buy a new baseball bat. The baseball bat costs $97.99. Ryan had saved enough money to pay 38% of the cost of the bat. How much money did Ryan have to help pay for the bat?
Answer my question for 10 points
Answer:
Hello! The answer is $37.24.
Step-by-step explanation:
By simple calculations, 38% of $97.99 equates to $37.2362. However, since this is a money-based question, we have to round the last two numbers up - which basically equals $37.24!
Answer:
Ryan had $37.24

What is the value of x? Show your work.
[tex] \frac{30}{25} = \frac{4x - 4}{20} \\ [/tex]
[tex] \frac{5 \times 6}{5 \times 5} = \frac{4x - 4}{20} \\ [/tex]
[tex] \frac{6}{5} = \frac{4x - 4}{20} \\ [/tex]
Multiply both sides by 20
[tex]20 \times \frac{6}{5} = 20 \times \frac{4x - 4}{20} \\ [/tex]
[tex] \frac{5 \times 4 \times 6}{5} = 4x - 4 \\ [/tex]

y = 32, x = 43
To figure this out, you have to use what you know to find all sorts of measures.
Lets start with the 75 degree angle. We know that the opposite side is a vertical angle, so that is also equal to 75 degrees. Since the angle to the big triangle is a supplementary angle, we know that the sum of 75 degrees and that angle is 180 degrees. Do the math and we get 180 - 75, or 105 degrees. The angles of a triangle always add up to 180, so 105 + 43 + y = 180. Solve for y: [tex]148+y=180=148-148+y=180-148=y=32[/tex]. So y is equal to 32 degrees. Now to find x, we know that the bases of the triangles are parallel, and that there is a line that goes straight from angle y to one of our unknown angles. Because the triangle bases are parallel and the y to unknown line does not change, we can tell that those are the same. So y = unknown angle 1, or 32 = 32. So, we know the measure of one angle. The other unknown angle is vertical to the other angle we found earlier, 105. So, we get 105 + 32 + x = 180. Evaluate: [tex]32+105+x=180=137+x=180=137-137+x=180-137=x=43[/tex]. So x is equal to 43.

x is a whole number such that 7x – 3 > 18
Write down the smallest value of x.
7x - 3 > 18
Add 3 to both sides
7x > 21
Divide both sides by 7:
X > 3
Since x has to be greater than 3 the smallest whole number that would work is 4
Answer: 4
Answer:
see below
Step-by-step explanation:
7x – 3 > 18
Add 3 to each side
7x – 3+3 > 18+3
7x> 21

7x/7 >21/7
x > 3
