15*5.5 = 82.5
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
550 + 550 = 1100
9x + 7 = 15x + 1 ___-1_______-1 9x + 6 = 15x -9x_____-9x ____6=6x ____/6_/6 ____1=x x equals 1.
Here is the answer with Steps: 15x - 18 = -2x - 5 15x = -2x + 13 17x = 13 x = 13/17 x ~ .764705882
15x+25y = 315 25y = -15x+315 y = -0.6x+12.6 which is now in slope-intercept form
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
550 + 550 = 1100
When X = 4, 15X = 15 * X = 15 * 4 = 60
15x = 360 Algebrauically rearrange x = 360/15 Cancel down by '5' x = 72/3 Cancel down by '3' x = 24/1 x = 24 The answer!!!!!
9x + 7 = 15x + 1 ___-1_______-1 9x + 6 = 15x -9x_____-9x ____6=6x ____/6_/6 ____1=x x equals 1.
The total magnification is calculated by multiplying the magnification of the ocular lens by the magnification of the objective lens. In this case, 15x magnification by 15x magnification equals a total magnification of 225x.
55
Here is the answer with Steps: 15x - 18 = -2x - 5 15x = -2x + 13 17x = 13 x = 13/17 x ~ .764705882
15x+25y = 315 25y = -15x+315 y = -0.6x+12.6 which is now in slope-intercept form
23 + 15x - 4x = 1215x - 4x = 12 -2311x = -11x= -1
77% of 550 equals 385.
X=-0.6
