Answer:
Step-by-step explanation:
The price is x
50% of the price is $35
- x*0.5 = 35
- x = 35/0.5
- x = 70
Answer is $70
Answer:
I believe that you would shade the one in the bottom right corner, but you might want to double check
Step-by-step explanation:
you take a (x,y) coordinate from each quadrant and plug in the numbers to see if the equation is correct. If it isn't, you do not shade that quadrant.
so for example, y<1/2 x
say your coordinate is (2,1)
you plug in the numbers so that it looks like 1>1/2×2.
1/2 × 2 is 1,
so therefore this equation is incorrect because 1 is not greater than one.
Answer
4x+1
−4,−2,0,2,4
Step-by-step explanation:
1. 2a=9b first we will divide the both sides with parameter b and get
2(a/b)=9 now we will divide both sides with number 2 and get
a/b=9/2 => a : b = 9 : 2
2. 6a-3b=5b first we will add to both sides number (+3) and get
6a=5b+3b => 6a=8b then divide the both sides with parameter b and get
6(a/b)=8 now we will divide the both sides with number 6 and get
a/b=8/6 if we simplify the fraction we get
a/b=4/3 => a : b = 4 : 3
3. a+b=3b we will add to the both sides parameter (-b) and get
a=3b-b => a=2b then divide the both sides with parameter b and get
a/b=2 => a/b=2/1 => a : b = 2 : 1
4. a/5=b/7 first we will divide the both sides with paremeter b and get
a/(5b)=1/7 now we will multiply the both sides with number 5 and get
a/b=5/7 => a : b = 5 : 7
Good luck!!!
Step-by-step explanation:
3x + 5y = 50
x + 5y = 31
use substitution
x = 31-5y
3(31-5y) +5y = 50
93 -15y + 5y = 50
93 - 10y = 50
--10y = -43
y = 43/10 = $4.30 for kids
now solve for x
x + 5(4.30) = 31
x + 21.5 = 31
x = $9.5 for adults
