2(3x + 4) = 6x + 8
3(x - 5) = 3x - 15
6x + 8 - 3x + 15 = 3x + 23

Find x when X to the power of -5 thirds equals 4 without using a calculator?
x^(-5/3) = 4 1/x^(5/3) = 4 x^(5/3) = 1/4 [x^(5/3)]^(3/5) = (1/4)^(3/5) x = 1/4^(3/5) or, x = 4^(-3/5) Check: x^(-5/3) = 4 [4^(-3/5)]^(-5/3) = 4 ? 4 ^(15/15) = 4 ? 4^1 = 4 ? 4 = 4
What is x-4x 5 in algebra?
x-4x=5 (1)x-(4)x=5 (-3)x=5 x= 5/(-3) x= -5/3
How do you graph 3x plus 4y equals 5?
3x + 4y = 5To find the x-intercept, let x = 03(0) + 4y = 54y = 5y = 5/4The line passes through (0, 5/4), so y-intercept is 5/4.To find x-intercept, let y = 03x + 4(0) = 53x = 5x = 5/3The line passes through (5/3, 0), so x-intercept is 5/3.Plot (0, 5/4) and (5/3, 0). Draw a straight line through them.Or,3x + 4y = 53x - 3x + 4y = 5 - 3x4y = -3x + 54y/4 = (-3x + 5)/4y = (-3/4)x + 5/4So the slope will be -3/4 and the y-intercept is 5/4; (0, 5/4)We find the x-intercept when y = 0, so0 = (-3/4)x + 5/40 - 5/4 = (-3/4)x + 5/4 - 5/4-5/4 = (-3/4)x(-5/4)/(-3/4) = [(-3/4)x]/(-3/4)5/3 = x ; (5/3, 0)Thus, the line passes through the points (0, 5/4) and (5/3, 0).
What is The Product Of 8 Decreased By 3 And 4 Decreased By 3?
(8 - 3) x (4 - 3) = 5 x 1 = 5
What is the LCM of 5 4 3 and 2?
The LCM is 60. 5 = 5 x 1 2 = 2 x 1 3 = 3 x 1 4 = 2 x 2 Using the highest exponent of each prime, the LCM is 5 x 3 x 4 = 60
Find x when X to the power of -5 thirds equals 4 without using a calculator?
x^(-5/3) = 4 1/x^(5/3) = 4 x^(5/3) = 1/4 [x^(5/3)]^(3/5) = (1/4)^(3/5) x = 1/4^(3/5) or, x = 4^(-3/5) Check: x^(-5/3) = 4 [4^(-3/5)]^(-5/3) = 4 ? 4 ^(15/15) = 4 ? 4^1 = 4 ? 4 = 4
Is multiplication distributive over multiplication?
No, multiplication is associative. 5 x (4 x 3) = 4 x (5 x 3) = 3 x (5 x 4) = 5 x 4 x 3 = 60
What is three fourths of four fifths?
3/4 x 4/5 = 12/20 = 6/10 = 3/5 or three fifthsNotice that the fours cancel out. Think about writing it as:3 x (1/4) x 4 x (1/5) = 3 x [(1/4) x 4] x (1/5) = 3 x [1] x (1/5) = 3 x (1/5) = 3/5.
What is 3 over 5 times 5 over 12 times 4 over 15?
3/5 x 5/12 x 4/15 = 3 x 5 x 4/5 x 12 x 15= 5 x (3 x 4)/5 x 12 x 15= 1/15
What is 3 over 4 times 4 over 3 times 5 over 5?
4 times 3 over 5 = 12/5= 4 * 3/5= 4/1 * 3/5= 12/5
What is 1 4 times 5 3 times 3 4?
1/4 x 5/3 = 5/12 5/12 x 3/4 = 5/16
What is 5 x plus 4 if x equals 3?
If your expression is 5x + 4 = ? and x = 3, then the answer is 19. If the expression is 5(x + 4) = ? and x = 3, then the answer is 35.
What is x-4x 5 in algebra?
x-4x=5 (1)x-(4)x=5 (-3)x=5 x= 5/(-3) x= -5/3
What is 3 over x minus 5 minus 4 over 5 minus x in lowest terms?
3/x-5 - 4/5-x 3(5-x) -4(x-5) 15-3x-4x+20 35-7x
What does integer 5 x -4 x -3 equals?
5*-4*-3 = 60
3/4 x 5/8?
3/4 x 5/8 = 15/32 (0.46875)
What is 5 times three quarters?
5 x 3/4 = 5/1 x 3/4 = 5x3 / 1x4 = 15/4 Answer: 3 and 3/4
