8 0

Answer:

(2,4)

Step-by-step explanation:

y = 4x - 4

2x + 3(4x - 4) = 16

2x + 12x - 12 = 16

14x = 28

x = 28/14

x = 2

y = 4(2) - 4

y = 8 - 4

y = 4

how do you get the answer for 1 5 over 8 and decimal 1.625 PLZ HELP I WILL GIVE YOU 50 POINTS FOR THIS
frutty [35]
1.625 as a fraction is 1 5/8

15/8 simplified is 1 7/8

if you are using the word "and" to represent multiplication here you go:

first i would change both fractions to a mixed number

13/8×15/8=195/64
simplify

your answer would be 3 3/64

if you are using "and" to represent adding here you go:

1.625 as a fraction is 1 5/8

first i would change 1 5/8 to a mixed number:  13/8

so then add 15/8+13/8=28/8

simplify:  
28÷4=7
8÷4=2

7/2=3 1/2
  
i hope this helped

Gill rolls a number cube 78 times. How many times can he expect to roll an odd number greater than 1?
bekas [8.4K]
Im assuming its just a regular number cube with 6 numbers 
there are only 2 odd numbers above 1 ( 3 and 5) 

so the ratio is 2/6 

you want to know how manny times (x) will you roll those numbers out of 78 roll 
the ratio is x/78 

multiply 

(2/6) = (x/78) 

cross multply to give you 6x= 156 and divide by 6 

<span>to give you x = 26

Draw a model to find 3/4 / 1/8
Vera_Pavlovna [14]
We would draw 3/4 next to 1/8, and see that 3/4 is 6 times the size of 1/8 so we would see that 3/4 = 6/8, so 6/8+1/8=7/8
