¿como se resolveria?
Answer:
12/7
Step-by-step explanation:
5/3x+10/7=30/7
5/3x=30/7-10/7
5/3x=20/7
x=(20/7)/(5/3)
x=(20/7)(3/5)

Matt wants to hire a company to detail his car. Company A charges $15+17h where h represents the hours it takes to detail the car. Company B charges $20h where h represents the hours it takes to detail the car. For what number of hours is the total amount charged for detailing the car the same for both companies?
Answer:
5 hours
Step-by-step explanation:
First, you set the equations equal, so 20h=17h+15
Second, you isolate the h, so you would subtract 17h from both sides, giving you 3h=15
Last, you divide both sides by 3 giving you h=5, meaning the companies charge the same price after 5 hours.
Answer:
5 hours

What is the slope ( in simplest form) of the line through the points (-4,2) and (-16,-6)?
Answer:
2/3
Step-by-step explanation:
Slope = [tex]\frac{y2-y1}{x2-x1}[/tex]
(-4,2) = (x1,y1)
(-16,-6) = (x2,y2)
Slope = [tex]\frac{-6-2}{-16+4}[/tex]
= [tex]\frac{-8}{-12}[/tex]
= [tex]\frac{2}{3}[/tex]

flour = 1/3 of rice
flour = 1/3 x 33 or 33/3
flour = 11kg
Find g(x), where g(x) is the translation 3 units down of f(x) = x2.
Write your answer in the form a(x - h)? + k, where a, h, and k are integers.
i hate ixl
Answer:
g(x) = x² - 3
Step-by-step explanation:
When doing a, h, and k, there are different stanoints to each of the variables.
in this case, since we are shifting down, we use k
we are moving 3 units down so we subtract 3 with no parentheses
so g(x) = x² -3
The translating function is g(x) = ( x+ 3)².
What is Translation?In mathematics, a translation is the movement of a shape to the left or right and/or up or down. The translated shapes appear to have the same size as the original shape, and hence the shapes are congruent. They were simply relocated in one or more directions. There is no change in the shape because it is just moved from one location to another.
We have function,
f(x) = x²
and, g(x) = a horizontal translation of 3 units left.
Now, we have to subtract 3 from the x coordinate of g(x).
So, g(x) = f(x-h) where h = -3.
Thus, the translating function is g(x) = ( x+ 3)².

Find the volume of the figure. Round to the nearest tenth if necessary.
1 point
3.4 in
4.8 in
25
Answer: 34 in^3
Step-by-step explanation:
Surface area of triangle = 1/2 x 3.4 x 2.5 = 4.25
To find the volume of the prism, multiply the surface area of the triangle by length.
So 4.25 x 8 = 34 in^3
Write the repeating decimal as a mixed number.
Answer:
1 1/30
Explanation:
we know that 0.3 (recurring) is equivalent to ⅓. thus, we can find 0.03 (recurring) by adding an extra decimal behind the denominator to get 1/30.
accounting for the 1, we can now get 1 1/30.

What is 0.14 4 recurring as a fraction
Answer:
0.1414... in a fraction is 14/99
Step-by-step explanation:
Given the number 0.1414...
we have to represent the above in terms of fraction
Let x=0.1414.... → (1)
Multiplying by 100 on both sides
100x=14.1414.... → (2)
Subtract (1) from (2), we get
99x=14
x=14/99
hence, 0.1414... in a fraction is 14/99

the s would 8 because
12+5 is 17
17-9 would be 8 so we would add 8.
9+3+16+3+5+12+10+8
Answer:
66 m
Step-by-step explanation:
We know that Perimeter is sum of all the sides of any triangle / quadrilateral / polygon . Here we see that that the side lenght are ,
8cm , 10cm , 12cm , 3m , 5m , 16m ,9m , 3cm .
On adding these , we will get Perimeter .
⇒ P = 8cm + 10cm + 12cm + 3m + 5m + 16m + 9m + 3m
⇒ P = 66m
Hence the required answer is 66mThe starting salary of a starting teacher is $40,000, which will increase by 2% each year.
What would this teacher’s salary be after 8 years of teaching round to the nearest dollar.
Answer:
$46,866
Step-by-step explanation:
Use the compound amount equation A = P(1 + r)^t, where r is the annual interest as a decimal fraction.
Here we have A = ($40,000)(1 + 0.02)^8, or
A = A = ($40,000)(1.02)^8 = $46,866
