Answer:
x=64
Step-by-step explanation: because the sides are both the same so do 128/2 which equals 64 so x=64
Answer:
60/4 is 45 and 38 times 1.15 is 43.70 kohls is more expensive
Step-by-step explanation:
Answer:
x = 0 1 -1 -2
y = -3 -4 -2 -1
Step-by-step explanation:
equation : 3y+9x = -9
when x = 1
3y+3x = -9
or, 3y + 3×1= -9
or, 3y+3=-9
or, 3y = -12
so, y = -4
Again
Let's suppose x as -1
3y+3x= -9
or, 3y+ 3×-1 = -9
or, 3y-3 = -9
or, 3y = -6
y = -2
Let's suppose x as -2 now,
3y+3x = -9
3y+3×-2 = -9
or, 3y-6 = -9
or, 3y = -3
so, y = -1
Answer:
r=20
Step-by-step explanation:
to get rid of the division part, you multiply 6 each side. now you have r+10=30. to solve, now you subtract 10 from both sides. this gives you r=20 :)
