3=x

y=-x+7
y=-(3)+7
y=4

(2x+1)+2x=5
2x+1+2x=5
4x+1=5
4x+1-1=5-1
4x=4
4x/4=4/4
x=1

Can someone help me do this
stealth61 [152]

Answer:

False.

Step-by-step explanation:

The ratio is 1:500, which means that the model will be 500 times smaller than the real deal.

The real airplane is 50 metres, or 5,000 centimetres. The model is 50 cm. 5,000 / 50 = 1,000 / 10 = 100 / 1 = 100. Since 100 is NOT equal to 500, the answer is false.

Hope this helps!

Hazel is putting together charm bracelets. For each bracelet she uses
Reika [66]

<u><em>Answer:</em></u>

37/96

<u><em>Explanation</em></u>:

Hazel uses 1yd for 60 charms, so for 5/8yd she would use 5/8×60=37.5.

Because she can’t use a fraction of a charm, she would use 37 charms which is 37/96 of the charms she has.
