10(y+2)-y=2(9y-8)
Mutiply the first bracket by 10
Mutiply the second bracket by 2
(10)(y)(10)(2)= 10y+20
(2)(9y)(2)(-8)= 18y-16
10y+20-y= 18y-16
10y-y+20= 18y-16
9y+20= 18y-16
move 18y to the other side
sign changes from +18y to -18y
9y-18y+20= 18y-18y-16
-9y+20= -16
move +20 to the other side
sign changes from +20 to -20
-9y+20-20=-16-20
-9y= -36
divide by -9
-9y/-9= -36/-9
y= 4
Answer: y= 4
Answer:
8x+12
Step-by-step explanation:
Remember that perimeter is all the sides combined. A rectangle has the same length and width for both sides.
P=2l+2w
P=2(4x-6)+2(12)
P=8x-12+24
P=8x+12
D.greater than or equal to one
Step-by-step explanation:
The standard form of equation of a line is ax + by + c = 0. Here a, b, are the coefficients, x, y are the variables and c is the constant term. The other different forms to find and represent the equation of a line are slope-intercept form, point-slope form, two-point form, intercept form, and normal form.
Given the mass of each box, and the total number of boxes, multiply both quantities to obtain the total mass, as shown below
Therefore, the answer is 24kg.
