Answer:

10w ≥ 30

Step-by-step explanation:

First, the variable w represents the "sum of a number and 15", so we don't know the missing value. Therefore the first part is 10w. The inequality is ≥ because it represents "at least 30". Your inequality should be 10w ≥ 30

Hope this helps!

Y=-2x+1<br>4x+y=9 <br>solve using the substitution method please show steps​
WINSTONCH [101]

Answer:

x = 4

y = -7

Step-by-step explanation:

y = -2x + 1

4x + y = 9

4x + y = 9

4x + (-2x + 1) = 9

4x - 2x + 1 = 9

2x + 1 = 9

2x = 9 - 1

2x = 8

x = 8/2

<u>x = 4</u>

4x + y = 9

4(4) + y = 9

16 + y = 9

y = 9 - 16

<u>y = -7</u>
