Answer:
y=-2+x/3 OR y=x/3-2
Step-by-step explanation:
x-3y=6
minus x from each side
-3y=6-x
change the symbols
3y=-6+x
divide by 3
y=-2+x/3
if you want, you can make it look better by switching it around to:
y=x/3 -2
Solve the system by using a matrix equation.
6x-9y= 3
3x-4y=7

1. add negative fraction with positive fraction
-7/8 + 1/4 = ?
2. add negative decimal with positive decimal
-12/5 + 15.3 = ?
Given parameters:
1. [tex]-\frac{7}{8} + \frac{1}{4}[/tex]
[tex]-\frac{7}{8} + \frac{1}{4}[/tex]; find the LCM = 8
= [tex]\frac{-7 + 2 }{8}[/tex]
= [tex]\frac{-5}{8}[/tex]
2. [tex]-\frac{12}{5} + 15.3[/tex]
Make the fraction decimal;
[tex]-\frac{12}{5}[/tex] = -2.4
So;
-2.4 + 15.3 = 12.9
-2,-7,-12 ,.... is an arithmetic sequence Find the sum of its first 20 terms ?
Given sequence:
-2,-7,-12 ,..
Unknown;
Find the sum of the first 20 terms = ?
Solution:
The sequence is -2,-7,-12 ,..
To find he sum of n-terms of a sequence, we use the expression below;
Sₙ = [tex]\frac{n}{2} (2a + (n-1)d)[/tex]
where n is the number of terms = 20
a is the first term = -2
d is the common difference= -7 - (-)2 = -5
Now input the parameters and solve;
Sₙ = [tex]\frac{20}{2} (2(-2) + (20 - 1) x -5)[/tex]
Sₙ = 10(-4 + -5(19)) = 10(-99) = -990
The sum of the first 20 terms of the sequence is -990
2/3 divided by 4/5 qwertyuioppasdfghjklzxcvbnm
Answer:
5/6
Step-by-step explanation:
The solution of the given fraction is 5/6.
Given that:
Fraction: divided 2/3 by 4/5
To calculate the division of fractions, simply need to multiply the first fraction by the reciprocal of the second fraction.
[tex]\dfrac{2/3}{4/5} =\dfrac{2}{3} \times \dfrac{5}{4}\\\dfrac{2/3}{4/5} =\dfrac{(2 \times5)}{(3 \times4) }\\\dfrac{2/3}{4/5} =10 / 12[/tex]
To simplify the fraction, you can divide both the numerator and the denominator by their greatest common divisor, which is 2:
10 / 12 = 5 / 6
So, 2/3 divided by 4/5 is equal to 5/6.
Hence, the required result is 5/6.

Find the length of d in the figure below if a = 8 in., b = 3 in., and c = 4 in. Round your answer to the nearest tenth.
Answer:
Let's see what to do buddy...
Step-by-step explanation:
_________________________________
Step (1)
First we find the diameter ((h)) of the rectangle on the floor using the Pythagorean theorem.
So we have :
[tex] {h}^{2} = {a}^{2} + {b}^{2} [/tex]
[tex] {h}^{2} = 64 + 9 [/tex]
[tex] {h}^{2} = 73 [/tex]
[tex]h = \sqrt{73} [/tex]
_________________________________
Step (2)
Now we another using of Pythagorean theorem for finding d :
[tex] {d}^{2} = {h}^{2} + {c}^{2} [/tex]
[tex] {d}^{2} = 73 + 16 [/tex]
[tex] {d}^{2} = 89 [/tex]
[tex]d = \sqrt{89} [/tex]
[tex]d = 9.4[/tex]
_________________________________
And we're done.

Marcus is making homemade barbecue sauce. The recipe calls for 3 cups of ketchup for every 1/2 cup of mustard. What is the rate in cups of ketchup per cup of mustard?
Answer: 6 cups of ketchup per cup of mustard
Step-by-step explanation:
Given : The recipe calls for 3 cups of ketchup for every [tex]\dfrac12[/tex] cup of mustard.
That means , for [tex]\dfrac12[/tex] cup of mustard. we need 3 cups of ketchup.
By using proportions, if we multiply 2 on both sides ,we get

The same amount of principal is invested in different accounts earning the same interest rate.
Which of the following accounts would have the greatest accumulated value at the end of one year?
A.An account eaming no interest
B.An account eaming simple interest
C.An account eaming interest compounded annually
D.An account earming interest compounded daily
Answer:
D.An account earming interest compounded daily
Step-by-step explanation:
An account earning interest compounded daily would have accumulated the greatest value at the end of the year.
Compound interest is interest on interest. In compound interest, the interest is calculated on the principal and interest accrued. This makes the value highest. For the account compounded daily, the interest on interest is taken every day. It has a power of 365. For compound interest accrued annually, the interest compounded yearly. Simple interest is basically on the principal.Answer: D! On edge 2021
