Answer:
how r u suppose to give 30 if it is only for 15
Step-by-step explanation:
Answer is b.
Now we going to solve it
To find how many refills he bought
8.95 + 1.50(r) = 26.95
-8.95 = -8.95 1. subtract $8.95 from
———————————- both sides.
1.50(r) = 18.00 2. The $8.95 cancels
——— = ——— out.
1.50 1.50 3. Bring the equation
R = 12 down.
4. Now you divide 1.50
on both sides.
Final answer R= 12
An area of rectangle: a · b
a = 0.4 km
b = 0.07 km
a · b = 0.4 km · 0.07 km = 0.028 km²
Answer:
hello how are you nice to meet you
Step-by-step explanation:
8, 12(3-x)=48
36-12x=48
-12x=48-36
-12x=12 both side divideos by -12
-12x/-12=12/-12
x= 1
9, x/7=4.5 cris cross
x=31.5
10,5(x-3)=45
5x-15=45
5x=45+15
5x=60 both side divided by 5
5x/5=60/5
x=12
11,-3(x-3)=45
-3x+3=45
-3x=45-3
-3x=42 both side divided by -3
-3x/-3=42/-3
x=14
12,14y-8=13
14y=13+8
14y=21 both side divided by 14
14y/14=21/14
y=1.5
13,3m=5m-8/5
3m-5m=-8/5
-2m=-8/5 cris cross
-10m=-8 both side divided by -10
-10m/-10=-8/-10
x=0.8
