Answer: What is the question????
answer:
32
Step-by-step explanation:
In the second equation you are given what Y equals, which is (-5x - 3). You would use this equation and plug it into the y value given in the first equation where it says 2y and solve
That would be
3x - 2(-5x - 3) = -6
3x + 10x + 6 = -6
3x + 10x = -6 - 6
13x = -12
X = -12/13
Then if you want to solve for Y you can use any equation and plug in the x-value found.
I’m going to use equation 2.
Y = -5x - 3
Y = -5(-12/13) - 3
Y = 4.615 - 3
Y = 1.615
(-12/13, 1.615)
Therefore the x-value is -12/13 and the y-value is 1.615.
Answer:
15 batches of cookies
Step-by-step explanation:
We need to find out how many third cups do into 5 cups. We can do this by 5 ÷ 1/3
When dividing fractions, use KFC:
- Keep the first fraction the same
- Flip the second fraction
- Change the sign from ÷ to ×
Therefore, 5 ÷ 1/3 = 5 × 3/1 which is 15 batches of cookies
Hope this helps!
Answer:
y=4.5x+40
16 pairs of shoes
Step-by-step explanation:
Let the target earnings be represented by y and the number of pairs of shoes that Roger sells be x hence
y=4.5x+40
The equation is therefore, y=4.5x+40.
To solve this equation, substitute the value of y with 112 hence
112=4.5x+40
4.5x=112-40=72
x=72/4.5=16
Therefore, Roger should sell 16 pairs of shoes to achieve his target earnings of $112
