Answer:
10cm, 5cm, 7cm.
Step-by-step explanation:
So basically what I did was I pretended the line was a ruler that was in centemeters, and all the lines were centimeters, so then I added it up to get my answer, as you can see in the picture
The correct answer would be 1/3 cup of sugar for every 1 teaspoon of vanilla, so A.
Hope this helps :)
Answer:
Step-by-step explanation:
Let
x-------> the number of pies
we know that
-----> linear equation that represent the situation
solve for x
Round to the nearest whole number
Answer:
14 arcade games and 8 photobooths were purchased
Step-by-step explanation:
x will represent the number of arcade games
y will represent the number of photobooths
We know that 22 total machines were bought which means that x+y=22
We also know that the total was 53600 which means that 2000x+3200y=53600
We can use substitution to solve this
x+y=22
x-22= -y
-x+22=y
Then plug this in for y in the next equation
2000x+3200(-x+22)=53600
Solve this and get x=14
Then plug in x=14 into any equation (I will choose the x+y one because that's easiest to solve)
14+y=22
this means y=8
This means that 14 arcade games and 8 photobooths were purchased
I double checked the math on desmos and it is correct
Answer:
x = 3
y = -1
Step-by-step explanation:
<em><u>To solve this, you can use the elimination method, which is to have one pair of terms to cancel one another. In this case, we already have 3y and -3y, which cancel:</u></em>
2x + 3y = 3
7x - 3y = 24
___________
9x = 27
<u>Divide both sides by 9:</u>
x = 3
<u>Plug in 3 for x, into one of the equations:</u>
2x + 3y = 3
2(3) + 3y = 3
6 + 3y = 3
<u>Subtract 6 from both sides:</u>
3y = -3
<u>Divide both sides by 3:</u>
y = -1
