Answer:

(8,130)

Step-by-step explanation:

y=10x+50

y=5x+90

They are both equal to each to y, so they are equal to each other.

10x+50=5x+90

Now, you want to get the variable on one side, so you subtract 50 from both sides, then 5x from both sides;leaving you with:

5x=40

Divide by 5 on both sides

x=8

Now, that you have x, plug it into any equation of y. For example...

y=10(8)+50

y=80+50

y=130

Which value of y forms the solution of the system defined by y = 11x + 1 and 11x + 12y = 12?

aliya0001 [1]

Y = 11 x + 1
11 x + 12 y = 12
----------------------
11 x + 12 * ( 11 x + 1 ) = 12
11 x + 132 x + 12 = 12
143 x + 12 - 12 = 12 - 12
143 x = 0
x = 0
y = 11 * 0 + 1
y = 0 + 1
Answer:
y = 1

Rewrite the following in ascending order. 9/25, 2/5, 14/-75, -19/10, 8/15

madam [21]

Step-by-step explanation:

Given numbers are 9/25 ,2/5, 14/-75, -19/10, 8/15

The denominators = 25 , 5, 75, 10, 15

LCM of the denominators = 150

9/25 = (9/25)×(6/6) = 54/150

2/5 = (2/5)×(30/30) = 60/150

14/-75 =(-14/75)×(2/2) = -28/150

-19/10 = (-19/10)×(15/15) = -285/150

8/15 = (8/15)×(10/10) = 80/150

Ascending order of the numbers

= -285/150, -28/150, 54/150, 60/150, 80/150

-19/10, 14/-75, 9/25, 2/5, 8/15

Least to gratest 0.3,19/50,22%

Alborosie

Answer:

22% 0.3 19/50

Step-by-step explanation:

Because 22%

0.3=30%

19 out of 50 percentage would be a 38%

So first is 22% then since 0.3=30% it's next andthen 19 out of 50 since that= 38% And then there you go.

Have a great day :)
