Answer:
4x - 6
Step-by-step explanation:
6 less is -6
product of four and a number x is 4x
D + 3r = 15
d = r + 3
r + 3 + 3r = 15
4r + 3 = 15
4r = 15 - 3
4r = 12
r = 12/4
r = 3 ....he bought 3 roses, at $ 3 per rose = $ 9 <==
d = r + 3
d = 3 + 3
d = 6....he bought 6 daisies, at $ 1 per daisy = $ 6
Given:
Total number of pieces: 117
watch = x
earrings = four times as many earring as watches = 4x
necklaces = half the number of necklaces as earrings = 1/2 * 4x = 2x
bracelets = necklaces = 2x
x + 4x + 2x + 2x = 117
9x = 117
x = 117/9
x = 13
watches: x = 13
earrings: 4x = 4(13) = 52
necklaces: 2x = 2(13) = 26
bracelets: 2x = 2(13) = 26
13 + 52 + 26 + 26 = 117
There are 13 watches, 52 earrings, 26 necklaces, and 26 bracelets.
