Answer:
a-135 hot dogs and 245 sodas were sold.
Step-by-step explanation:
Our equations are:
1.25h + 0.75s = 352.50
h + s = 380
Let's use substitution to solve for this system. In the second equation, let's write h in terms of s:
h + s = 380
h = 380 - s
Now, let's plug in 380 - s for h in the first equation:
1.25h + 0.75s = 352.50
1.25(380 - s) + 0.75s = 352.50
We can now solve for s fairly easily:
1.25(380 - s) + 0.75s = 352.50
475 - 1.25s + 0.75s = 352.50
0.5s = 122.5
s = 245 sodas
We can already see which answer choice will match: A, and that is our answer.
Y-5 = (5-7)/(0+2) (x+2)
y-7 = -2/2 (x+2)
y -7 = -x-2
y = -x+5

Percent increase
find increase first
10500 to 11300
11300-10500=800
so
percent increase
change/original
origianal=10500
change=800
800/10500=8/105=0.0761
percent means parts out of 100
0.0761/1 times 100/100=7.61/100=7.61%
rond 7.61% to tenth or to 7.6%
7.6%
Answer: 3/5
Step-by-step explanation:
Probabilty of blue tiles: 12/20 =3/5
Probability of letter b tiles: 10/20= 1/2
How to get the denominator?
4+6=10
2+8=10
10+10=20
