Answer:
The first equation should be multiplied by 9 and the second equation by −4
Step-by-step explanation:
Given the simultaneous equation
First Equation: 5x − 4y = 28
Second equation: 3x - 9y = 30
In order to eliminate y, we must make the coefficient of x in both expression to be equal.
To do that the first equation should be multiplied by 9 (negative value of the coefficient of y in equation 2)and the second equation by -4( (coefficient of y in equation 1)
It would be an enlargement, because 5/2=2.5 which is greater than 1. Hope this helps!
<span>They should produce 100 Explorers and 275 Grande Expeditions.
To maximize revenue, we want to use all 375 frames. Since the more expensive bike take longer to make, we also want to use all 450 hours so we can make as many of the more expensive bikes as possible with the 375 frame. This helps us create a 2 variable system that can be solved.
Let x=Explorers and y=Grande Expeditions
x+y=375
2x+3y=450</span>
Answer:
Step-by-step explanation:
Negative 20 plus 20 equals 0
70, because 528 divides by 264 is 2, which means each picture is 2 megabytes, so therefore 35x2 = 70
