Answer:
15% if I remember correctly
First you'll need to get the same denominator. So instead of 3/5 and 3/8 you'll have 24/40 and 15/40. Now that we've changed the value of the denominator, the 40/40 will now represents the 1 hour that Jenny has before bedtime. So you add 24/40 and 15/40 and get 39/40. 39/40 stands for the time that Jenny has already spent brushing her teeth and texting her friend all together. Since the 1 hour is 40/40 subtract 39/40 from it to get 1/40. 1/40 is equal to the rest of the time Jenny spends reading or 1.5 minutes.
Answer:
280.
Step-by-step explanation:
-0.05×14= 280 280× -0.05=280

Your answer is B.
x > y - 1
x < -y -3
Step-by-step explanation:
x−y+2z=0
Step 1: Add y to both sides.
x−y+2z+y=0+y
x+2z=y
Step 2: Add -2z to both sides.
x+2z+−2z=y+−2z
x=y−2z
Answer:
x=y−2z
x−2y+3z=−1
Step 1: Add -x to both sides.
x−2y+3z+−x=−1+−x
−2y+3z=−x−1
Step 2: Add -3z to both sides.
−2y+3z+−3z=−x−1+−3z
−2y=−x−3z−1
Step 3: Divide both sides by -2.
−2y/−2 = −x−3z−1/−2
y= 1/2 x+ 3/2 z+ 1/2
Answer:
y= 1/2 x+ 3/2 z+ 1/2
2x−2y+z=1
Step 1: Add 2y to both sides.
2x−2y+z+2y=1+2y
2x+z=2y+1
Step 2: Add -z to both sides.
2x+z+−z=2y+1+−z
2x=2y−z+1
Step 3: Divide both sides by 2.
2x/2 = 2y−z+1/2
x=y+ −1/2 z+ 1/2
Answer:
x=y+ −1/2 z+ 1/2
