2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10
<em>add 10 to each side</em>
<em>5x-10+10 = 10 + 10</em>
<em>5x=20</em>
5x = 0 <em>this is the error</em>
He needs to add 10 to each side
Answer: The length of the beetle in the drawing is 9 cm.
Step-by-step explanation:
Hi, since is a scaling up scale, we have to multiply the original length of the beetle (1.8 cm) by 5 to obtain the length of the beetle in the drawing.
Mathematically speaking
5 x 1.8 = 9 cm
The length of the beetle in the drawing is 9 cm.
This type of scale is used to increase in size.
