Directions: Solve each equation. Show all work and check your answers. #1 8x + 5 = 6x + 1 x - 1 = -5 - x
#2 10x + 18 = 8x + 4 8 + 4x = 9x - 7
#3 5x - 7 = 2(x + 1) 3(x + 12) = 8 - 4x
#4 5x - 7 = 2(x + 1) 3(x + 12) = 8 - 4x
#5 9x = 6(x + 4) 40 + 14x = 2(-4x -13
#6 3(x + 12) = 8 - 4x
#7 9x = 6(x + 4)
#8 40 + 14x = 2(-4x -13)

5x - 7 = 2(x + 1) 3(x + 12) = 8 - 4x
9x = 6(x + 4) 40 + 14x = 2(-4x -13

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
