When x = 4 and y = 3, find the value of:
a) 2x + 7y - 10
b) y(x - 2y)
c) (5y - 3x)/12​

a) 2*4+7*3-10 = 25

b) 3(4-2*3) = -6

c) (5*3-3*4)/12= 4

Step-by-step explanation:

just replace the variables with the numbers given .

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

70.30
