3 times the difference of x and y?
3(x - y)
If x plus y equals 3 and yx equals 2 then y is equal to what?
If x+y = 3 and y times x = 2 then y = 1.
Is the value of y equal to 3 times the value of x?
Then y = 3x.
If y varies directly as x and y 36 x 9 then what is the value of x when y 12?
If y varies directly as x and y is 36 when x is 9, then y is always four times the value of x. So if y is 12, then x is 3.
What are two numbers whose sum is 33 and difference is 3?
Let one of the numbers be x and other be y.Sum is 33: x + y = 33 ...(1)Difference is 3: x - y = 3 ...(2)Let's add these equations:(x + y) + (x - y) = 33 + 32x = 36x = 18Putting the value of x in equation 1, we get18 + y = 33y = 33 - 18 = 15The two numbers are 18 and 15.15 and 18
3 times the difference of x and y?
3(x - y)
What does x times x times x times x times x equal?
x5 You have x*x*x*x*x just add up the amount of x's you have and put it after as an exponent Example: 3*3*3*3=34 y*y*y*y*y*y=y6
How would you write 3 times the sum of x squared plus 5 times the difference of 2x and y?
3[(x^2) + 5] x (2x-y) Do the parentheses first, then brackets next. P.e.m.d.a.s.
What are the factors of 45x4y?
If you meant (45x^4)(y), then the answer is: (3)(3)(5)(x)(x)(x)(x)(y) If you meant 45 times x times 4 times y, then the answer is: (2)(2)(3)(3)(5)(x)(y)
What is 9 times X times 2 over 3 times y?
(9) · (x) · (2/3) · (y) = 6 x y
What are the x and y intercepts for negative 3 times x minus 3 times Y times 8?
-3X - 3Y x 8
How would you write 3 times the sum of x and y squared plus 5 times the difference of 2x and y in verbal exprestion?
That verbal expression would read: 3(x+y)^2 + 5(2x -y) ^2 means 'squared' in the above example.
Two integers have a difference of -11 and a sum of -3 What are the integers?
Two integers (X & Y). X+Y=-3, X-Y=-11. x=-11+y --> (x)+y=-3 --> (-11+y)+y=-3 --> y=4 x=-11+4=-7 Hope that helps! Two integers (X & Y). X+Y=-3, X-Y=-11. x=-11+y --> (x)+y=-3 --> (-11+y)+y=-3 --> y=4 x=-11+4=-7 Hope that helps!
If x plus y equals 3 and yx equals 2 then y is equal to what?
If x+y = 3 and y times x = 2 then y = 1.
What is 36x2y factored?
2 times 2 times 3 times 3 times x times x times y
The sum of the real numbers x and y is 11. Their difference is 5. what is the value of xy?
x + y = 11 and x - y = 5. The y's cancel so you're left with 2x = 16. So x = 8. Plug x back in to one of the original equations to find y. 8 + y = 11. So y = 3. And 3 times 8 = 24.
Which equation can be used to find two numbers such that twice the first equals three times the second and three times their difference exceeds twice the second by 13?
Let the two numbers be x and y, then:Twice the first equals three times the second: 2x = 3yThree times their difference exceeds the second by 13: 3(x - y) = y + 13From equation (1) it is clear the first number (x) is greater than the second (y), so their difference is x - y.Equation (2) can be rearranged:3(x - y) = y + 13→ 3x - 3y = y + 13→ 3x = 4y + 13This gives two simultaneous equations:2x - 3y = 03x - 4y = 13which can then be solved to find the two numbers (x and y).
