8z=4(2z+1)
First you would distribute the constant into the numbers in the parentheses. so
8z=8z+4
then you would combine like terms which in this case would result in a zero.
8z-8z=0 So the z would be zero or no solution.

Step-by-step explanation:

pythagoras theorem: c²=a²+b²

Where c= longest side of a right angle triangle

AB= 6+r = c

AD= 12 =a

CD= r =b

(6+r)² = 12²+ r²

36+12r+r² =144 +r²

12r+r²-r²=144-36

12r=108

r= 108/12

r=9

erastovalidia [21]

Answer:

Model A is 9

Model B is 5

Step-by-step explanation:

At Lisa's printing Company LLC there are two kinds of printing presses model.

Let x = the number of model A printing press.

Let y = the number of the model B printing press.

model A can print 70 bucks per day and model B can print 55 bucks per day.

The total number of both models prints 905 bucks per day.

This means

70x + 55y = 905 - - - - - - - - -1

The company owns 14 total printing presses. This means

x + y = 14 - - - - - - - - - -2

x = 14-y

Put x = 14-y in equation 1

70(14-y) + 55y = 905

980 -70y + 55y = 905

-15y = 905-980= -75

y = -75 / -15= 5

x = 14-y = 14-5

= 9

telo118 [61]

Answer:

Laura and Erica will both have made 16 blankets in one more day.

Step-by-step explanation:

i) Erica has made 10 blankets already.

ii) Erica can make 6 blankets more per day

iii) Laura has completed 6 blankets already

iv) Laura can complete 10 more blankets per day.

v) Let x be the number of days to the point when they will have completed the same number of blankets

vi) Therefore the number of blankets that Erica makes till x days is = to the number of blankets that Laura makes till x days

vi) therefore 10 + 6x  = 6 + 10x    ⇒   4x  = 4    ⇒ x = 1 day

vii) Therefore Laura and Erica will both have made 16 blankets in one more day.
