Answer: X=29
Step-by-step explanation:
First you substitute the x's: 2(3y-1)-5y=8
Then you open parenthesis:6y-2-5y=8
Combine like terms: y-2=8
Bring the 2 to the other side: y=10
Now you substitute the y with the answer: x=30-1
Easy equation: x=29

the quotient of a number x and 3 is at most 4
an inequality is ?
the solution is ?
Answer: The inequality is x/3 [tex]\leq[/tex] 4 and x [tex]\leq[/tex] 12
Step-by-step explanation:
The quotient of x and 3 is the same as x/3 and the at most sign is less than or equal to. x/3 has to be less than or equal to 4 which can be represented by the inequality,
x /3 ≤ 4 Solve for x by multiplying both sides by 3.
x ≤ 12

Answer:
52°
Step-by-step explanation:
If it is a right triangle, one interior angle is 90°, and we are also given the interior angle of 38°. The sum of any triangles interior angles will always be 180°.
90 + 38 = 128
180 - 128 = 52

Mrs. Canale’s class is selling frozen pizzas to earn money for a field trip. For every pizza sold, the class makes $5.35. They have already earned $182.90 toward their $750 goal. How many more pizzas must they sell to earn $750? Solve this problem first by using an arithmetic approach, then by using an algebraic approach. Compare the calculations you made using each approach
Answer:
106 more pizzas
Step-by-step explanation:
750-182.90
=567.1

If x-y=6 and x^2+y^2=24, find x^3-y^3.
Answer:
162.06
Step-by-step explanation:
sorry i'm not the best an explaining but i'm confident in my answer.
the first thing to do is get rid of the ² in x²+y²=24, we do this by √24 which ≅4.90 (i rounded to the hundreth place)
then we have this
x-y=6
x+y=4.90
I am using the elmination method. To do that you need to get two letters to have the same coefficient (in 4x 4 is the coefficient) with oposite signs (one possitive one negitive)
In our equation here we see that the same coefficient is 0, and there is oposite signs for y. Therefore we can add the two equations and get
2x=10.9 (the y cancels out)
now we have a simple equation and all that is left is to solve it
10.9/2=5.45
x=5.45
Now we need to find y we do that by pluging the x value into one of the equations I choose the first one becasue its easiest.
(5.45)-y=6
y= - .55
now that we have both x and y plug them into the final equation (5.45)³-(-.55)³= 161.89-(-.17) =162.06
Therefore x³-y³≅162.06!
(if you have any questions or would like to debate the answer please let me know!)

Step-by-step explanation:
a number x divided by 8 is less than -2
Answer: x/ 8 < -2 and x< -16
Step-by-step explanation:
A numer x is divided by 8 is the same as x/ 8 and x/8 has to be the less than -2 so it will be x/8 < -2
x/8 < -2 TO solve the inequality, multiply 8 on both sides to get
x < -16
The solution of expression is,
⇒ x < - 16
We have to given that,
An algebraic expression is,
''a number x divided by 8 is less than -2''
We can write as,
⇒ x / 8 < - 2
Solve for x,
⇒ x/8 < - 2
Multiply by 8;
⇒ x < - 2×8
⇒ x < - 16
Therefore, The solution of expression is,
⇒ x < - 16
