Answer:
54 mm
Step-by-step explanation:
A dilation is an enlargement or reduction of a line or figure using a scale factor. If the initial length of the line JK = 36mm, you can find the length of the new image of J'K' by multiplying the initial length by the scale factor:
36 * 3/2 = 108/2 = 54mm
Answer:
D
x is less than or equal to -3
Step-by-step explanation:
I hope I was fast enough ^^
First we calculate classroom surface:
35*40=1400 square ft
we know that for every 100 square ft 2 or 3 pots can be put
so 1400/100=14
14*2=28
14*3=42
we need 28 or 42 pots

Answer:
x=5 and y=5
Step-by-step explanation:
You "plug" one equation into the other, to get a new equation that only has one variable (x or y), then you can simplify that and have your answer.
So let's plug the first into the second:
First, we convert the first equation into an x=... form. For this one, this means moving the +y to the other side:
x = 10 - y
Now we substitute 10-y for x in the second equation:
So 2x+4y=30 becomes:
2(10-y) + 4y = 30
And simplify that:
20 - 2y + 4y = 30
20 + 2y = 30
2y = 30-20
2y = 10
y = 5
This is the first answer! If we put this into the first equation, we get:
x = 10 - 5 = 5
Now we have both answers, x=5 and y=5
