Answer:

5 inches

Step-by-step explanation:

(5 + x)(10 + x) = 6x²

x² + 15x + 50 = 6x²

5x² - 15x + 50 = 0

x² - 3x + 10 = 0

(x - 5)(x + 3) = 0

x = 5, x = -3

We want x to be positive, so x = 5.

Thus, each dimension must be increased by 5 inches.

lions [1.4K]

Answer:

y = -2x + 6

Step-by-step explanation:

y=mx + c

m is the gradient and c is the y intercept

m = (y 2 - y 1)  / (x 2 - x 1)  = (2-4) / ( 2-1) = -2

y= -2x + c

To find c, just sub one of the coordinates into the eqn:

By using the coordinates (1,4)

4 = -2(1) + c

c = 6

Therefore, the equation is y = -2x + 6

Mis wants to earn 2,000 in her job at a bicycle store. She is paid $55 for each bicycle she tunes up. The minimum number of bicy
Natali [406]

Answer:

Step-by-step explanation:

ok. you said 2000 and 2500 so I'll just solve for both.

this is very simple, mis/mia wants to earn 2000/2500 so let's solve

this can be done two ways. an equation way, or a dividing way. I personally like the dividing way.

2000 divided by 55= 36.36-- so she will have to tune up 37 bicycles

2500 divided by 55= 45.45-- so she will have to tune 46 bicycles. this is because 46 bicycles, times the amount of money == just a little over 2500 so she has reached  her goal

Answer: X=11

Step-by-step explanation:

                                     7x+ 13 = 90

                                                          (bring like terms together)

                                      7x=90-13

                                      7x=77

                                           therefore x= 11

HOPE THIS HELPS YOU....
