Solve for the given variable 7x+5y=6 for y
Answer:
y = (6/5) - (7/5) x
Step-by-step explanation:
goal: to rearrange the equation such that it takes the form:
y = f(x) ; where f(x) is an expression in terms of x
Given:
7x+5y=6 subtract 7x from both sides
5y = 6 - 7x (divide both sides by 5)
y = (6-7x) / 5
y = (6/5) - (7/5) x
7.83 x 7.83 - 1.17 x 1.17/ 6.66

I have to find rs and rt
Answer:
RS= 20
ST= 40
RT=60
Step-by-step explanation:
If you notice, RS and ST make up RT. Therefore, we add RS and ST, and set that equal to RT.
3x-16+4x-8=60 [combine like terms]
7x-24=60 [add both sides by 24]
7x=84 [divide both sides by 7]
x=12
Now that we know x, we can plug them into RS.
3(12)-16 [multiply]
36-16 [subtract]
20
We can also find ST.
4(12)-8 [multiply]
48-8 [subtract
40

2x-3 = -x+3 what does x equal
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
x = 2
Hope this helps! :)
Answer:
x = 2
Step-by-step explanation:
2x - 3 = - x + 3
First, combine the like terms
(Don't forget to change the signs with you bring a number or variable from one side to another.)
2x + x = 3 + 3
Then, add or subtract.
3x = 6
Divide.
x = 2
Hope this helps!

If the common differences of an Ap is 5, the value of a18-a13 is
Answer:
25
Step-by-step explanation:
The n th term of an AP is
[tex]a_{n}[/tex] = a₁ + (n- 1)d
where a₁ is the first term and d the common difference
Here d = 5, then
a₁₈ = a₁ + 17d = a₁ + 85
a₁₃ = a₁ + 12d = a₁ + 60
Thus
a₁₈ - a₁₃
= a₁ + 85 - a₁ - 60
= 25

Solve this please, and quick
Answer:
3.2
Step-by-step explanation:
7x + 12 + 9x = 7
16x + 12 = 7
- 12 -12
16x = -5
16 divided by -5 is 3.2
x = 3.2
What is the solution to this equation?
16x- 8x-12 = 24 + 20
O A. x = 5
O B. x=7
O c. x = 4
O D. x = 6
Answer:
x=7
Step-by-step explanation:
16x-8x-12= 24+20
(16x-8x)-12= 24 +20
8x - 12= 24 +20
8x = 24+ 20 + 12
8x = 54
x = 54/8
x= 7
Answer:
x=7
Step-by-step explanation:
1. combine like terms
2. isolate x
3. divide by 8 to get x

what is the result of converting 20 ounces into pounds?
Answer:
20 ounces is 1.25 pounds
Step-by-step explanation:
Answer:
20 ounces -> 1.25 pounds
Step-by-step explanation:
Divide the given ounce value by 16 or multiply the ounce value by 0.0625
20 oz /16 = 1.25 lbs
20 oz x 0.0625 = 1.25 lbs
Consider the function represented by 9x+3y = 12 with x as the independent variable. How can this function be
written using function notation?
ORD=-v+
O f(x) = -3x+4
OF) = -3y+ 4
Answer:
f(x) = - 3x + 4
Step-by-step explanation:
letting y = f(x) , rearrange making y the subject
Given
9x + 3y = 12 ( subtract 9x from both sides )
3y = - 9x + 12 ( divide all terms by 3 )
y = - 3x + 4, thus
f(x) = - 3x + 4 ← in functional notation

The following table gives the number of people picking strawberries in a field and the corresponding number of hours that those people worked picking strawberries. Graph the ordered pairs from the table
Answer:
Step-by-step explanation:
Ordered pair (x, y) on a graph shows the two values,
x - values → Horizontal distance of the point form the origin.
y - values → Vertical distance of the point from the origin.
Example:
If we have to ploy (1, 3) on the graph.
We will plot a point which has a horizontal distance of 1 unit (grid) and 3 units vertical distance from the origin.
Now we will plot the points given in the table.

Assume the Ziders continue to grow in the same pattern. How old would a Zider be that had 73 hairs?
Number of hairs in day 1 , a = 5.
Every day number of hairs increases by , d = 4.
So, it is an Arithmetic Progression with first term a = 5 and common difference d = 4.
So, number of hair in nth days is given by :
[tex]a_n=a+(n-1)d\\\\a_n=5+(n-1)4[/tex]
Let, after x days number of hairs are 73.
[tex]73=5+(x-1)4\\\\x-1=\dfrac{73-5}{4}\\\\x=18\ days[/tex]
Therefore, Zider is 18 days old.
Hence, this is the required solution.
Joshua wants to make cookies. To make cookies, he needs 1 1/8 cups of flour per batch of cookies. Joshua has 18 cups of flour. How many batches of cookies can he make? *
Answer: He can make 16 batches of cookies.
Step-by-step explanation:
Given: . To make cookies, Joshua needs[tex]1\dfrac18[/tex] cups of flour per batch of cookies.
i.e. 1 Batch requires =[tex]1\dfrac18[/tex] cups of flour
=[tex]\dfrac{9}{8}[/tex] cups [convert mixed fraction to improper fraction.]
Now if 1 batch = [tex]\dfrac{9}{8}[/tex] cups (i)
Then, 1 cup = [tex]\dfrac{8}{9}[/tex] batch. (ii) [Multiply (i) by [tex]\dfrac{8}{9}[/tex] ]
Joshua has 18 cups of flour.
That means , 18 cup = [tex]18\times\dfrac{8}{9}=2\times8=16[/tex] batch. [Multiply (ii) by 18]
∴ He can make 16 batches of cookies.
