Answer:
2
Step-by-step explanation:
6 plus 7 equals 13
9 plus 9 equals18
18 subtract 6 equals 13
13 subtract 12 equals 1
Answer:
For this scenario, I used the elimination method. Organize the equations, so it's easier to subtract from each other. My x-variable will represent the number of hot dogs and my y-variable will represent the number of sodas.
3x+2y=213
x + y =87
We need to make sure one of the monomials are alike in each equation, so we can eliminate a variable. Distribute 3 to each number/variable in the second equation.
3x+2y=213
3(x+y=87) --> 3x+3y=261
Now we can eliminate x.
3x+2y=213
- 3x+3y=261
----------------------
-y=-48
Divide -1 to both sides to get y=48. So, you sold 48 cans of soda. Now, we can find the number of hot dogs by substituting 48 into the second equation to get x+48=87. Subtract 48 to both sides to result with x=39. So, you sold 39 hot dogs.
60 = 40% * x ;
60 = ( 40 / 100 ) * x ;
60 = 2x / 5 ;
2x = 300 ;
x = 300 / 2 ;
x = 150 is full marks.
17.) (-2,0) & (5,0)
19.)(-8,0) & (-7,0)
20.)(-5,0) &(1.5,0)
21.)(-2,0) &(8,0)
I put all of them into Desmos the x’s or solutions are when the u shaped graphs pass through the x-axis
Please mark me the Brainiest
I'm pretty sure the answer is "19", but if i'm wrong please don't kill me.
