R-199=70
remember you can do anything to an equaton as long as you do it to both sides
r-119=70
add 119 to both sides
r+119-119=119+70
r+0=189
r=189
Answer:
0.12 cups
Step-by-step explanation:
What we need to get here is the proportion of cheese in each dish. This implies the ratio of cheese per dish.
Sarah used 2.5 cups for 10 people, which means 2.5/10 cups of cheese per dish. 2.5/10= 0.25
So, Sarah gave 0.25 cups of cheese to each dish.
If we make the same calculation for Aron, we have 1.6/12=0.13
Arun used 0.13 cups of cheese per dish.
For getting the difference we just need to subtract:
0.25-0.13=0.12
So, Sarah used approximately 0.12 cups of cheese per dish more then Arun.
Answer:
27 miles in the morning and 85 miles in the afternoon.
Explanation:
Let m be the number of miles they rode in the morning. They rode 4 more than 3 times this many in the afternoon; this gives us the expression
3m+4
to represent the miles ridden in the afternoon.
Together they rode 112 miles; this means we add the morning miles, m, to the afternoon miles, 3m+4, and get 112:
m+3m+4 = 112
Combine like terms:
4m+4 = 112
Subtract 4 from each side:
4m+4-4= 112-4
4m = 108
Divide both sides by 4:
4m/4 = 108/4
m = 27
They rode 27 miles in the morning.
That means in the afternoon, they rode
3m+4 = 3(27)+4 = 81+4 = 85 miles.

Answer:
-18 and -12
Or, 18 and 12
Step-by-step explanation:
Let the integers be 'a' & 'a + 6'.
Their product = 216
=> a x (a + 6) = 216
=> a² + 6a = 216
=> a² + 6a - 216 = 0
=> a² + (18 - 12)a - 216 = 0
=> a² + 18a - 12a - 216 = 0
=> a(a + 18) - 12(a + 18) = 0
=> (a + 18)(a - 12) = 0
=> a = - 18 or a = 12
Integers are: -18 and -18+6 = -12
Or, 12 and 12 + 6 = 18
