5x = 30 -5
5x = 25
x = 25/5 = 5
1. b. 5x + 24 = -6 - 4x
5x + 4 x + 24 = -6
9x + 24 = -6
9x = -6 - 24
9x = -30
x = -30/9 = -3 1/3

2. Bil Genap = 2n
Maka : 2n + (2n + 2) + (2n + 4) = 90
6n + 6 = 90
6n = 90 - 6
6n = 84
n = 84/6 = 14
Bil terkecil = 2n = 2 x 14 = 28
Bil terbesar = 2n + 4 = 2 x 14 + 4
= 28 + 4 = 32
Jadi jumlah bilangan terbesar dan terkecilnya adalah 32 + 28 = 60

penyelesaian :
Keliling : 2 x (p+l)
86 = 2(x+x-7)

6n = 90 - 6
n = 84/6 = 14
Bilangan terkecil = 2n = 2(14) = 28

Dit: Berapa jumlah bilangan terbesar dan terkecil?
Jawab:
Bilangan genap kita umpamakan sebagai = 2x

3. Diketahui:
P = p
I = p - 7

Ditanyakan:
Berapa ukuran lebar dan panjangnya?
JAWAB:
K = 2 (p + l)
86 = [ p + (p - 7) ]
86 = 2 (2p - 7)
86 = 4p - 14
86 + 14 = 4p
100 = 4p
4p = 100

6x = 90 - 6
6x = 84
x = 84/6
x = 14
Bilangan terkecil: 2x = 2(14) = 28
Bilangan terbesar: 2x + 4 = 28 + 4 = 32
Jadi, jumlah bilangan terbesar dan terkecil adalah 28 + 32 = 60

3) Diket:
p = p
l = p - 7
K = 86 meter
Dit: Berapa ukuran lebar dan panjangnya?
Jawab:
K = 2 (p + l)
86 = 2 [p + ( p - 7) ]
86 = 2 (2p - 7)
86 = 4p - 14
86 + 14 = 4p
100 = 4p
4p = 100
p = 100/4
p = 25

l = p - 7
l = 25 - 7
l = 18

Jadi, panjang kolam renang tersebut adalah 25 meter, sedangkan lebarnya adalah 18 meter.]]> 2021-02-08 01:04:30 UTC https://padlet.com/mintjemanenggek1/vw3lrkqrptozki5a/wish/1174736115 Fizzia Rezky Aqila/7D https://padlet.com/mintjemanenggek1/vw3lrkqrptozki5a/wish/1174747144 1.a.-30 + 5x = -5

2.Bilangan genap 2n
Maka : 2n + (2n + 2)+(2n + 4)= 90
6n + 6= 90
6n=90 - 6
n=84/6=14
bilangan terkecil = 2n = 2(14)=28
Jadi jumlah bilangan terkecil dan terbesar =28 + 32 = 60

3.Keliling persegi panjang

l=p -7
Keliling = 86

2p+2l= 86
2p+2(p-7)=86
2p+2p-14=86
2p+2p=86+14
4p=100
p=25

Jadi lebarnya 18 meter

1. A. -30 + 5x = -5
= 5x = 30 -5
= 5x = 25
= x = 25 / 5 = 5
B. 5x + 24 = - 6 – 4x
= 5x + 4x = -6 - 24
= 9x = -30
= x = 3 1/3

2. Bilangan genap = a
3 bilangan genap berurutan = a + (a + 2) + (a + 4) = 90
3a + 6 = 90
3a = 90 - 6
3a = 84
a = 84 / 3
a = 28
Jadi bilangan genap terkecil adalah a = 28
Bilangan genap terbesar adalah a + 4 = 28 + 4 = 32
Jadi jumlah bilangan genap terkecil dan terbesar adalah
28 + 32 = 60

3. Keliling persegi panjang =
2p + 2l
l = p - 7
keliling = 86

2p + 2l = 86
2p + 2 (p - 7) = 86
2p + 2p -14 = 86
2p + 2p = 86 + 14
4p = 100
p = 25

Jadi lebarnya
l = p - 7
l = 25 - 7
l = 18
Jadi lebarnya 18 meter

lebar = x -7
k : 86 cm

penyelesaian :
K = 2(P+L)
= 86 = 2 (x+x-7)
= 86 = 2 ( 2x - 7 )
= 86 = 4x - 14
= 86 + 14 = 4x - 14 + 14
= 100 = 4x
= 1/4 X 100 = 1/4 X 4x
25 =x

Jadi panjang : (x) 25 cm
Lebar (x-7) 18 cm

x = 90/3
x = 30
Bilangan terbesar dan terkecil
= (x - 2) + (x + 2)
= (30 - 2) + (30 + 2)
= 28 + 32
= 60
3.
Panjang
2x (p+l)
86 = 2x (p+p-7)
86 = 2x (2p-7)
86 = 4p - 14
86 + 14 = 4p
P = 100÷4
= 25 m
Lebar
l = p - 7
l = 25 - 7 = 18 m]]> 2021-06-14 12:12:51 UTC https://padlet.com/mintjemanenggek1/vw3lrkqrptozki5a/wish/1604908147 M. FACHRIL Farghali https://padlet.com/mintjemanenggek1/vw3lrkqrptozki5a/wish/1606159690 1)a.-30+5x=-5
5x=25
X=25/5=5
b. 5x+24=6-4x
9x=-30
X=30/9=3 1/3
2) jawab:
2n+(2n+2)=(2n+4)=90
6n+6=90
6n=90-6
n=84/6=14
Bilangan terkecil=2n
=2(14)
=28
Bilangan terbesar
2n+4
=2(14)+4
=32
Jumlah terbesar dan
Terkecil:32+28=60
3)dik panjang x
Lebar :x-7
Keliling 86 cm
Penye:
K=2(p+l)
86=2(x+x-7)
86=(2x-7)
86=4x-14
86+14=4x-14+14
100=4x
1/4x100=1/4x4x
25=x
Panjang X=25cm
Lebar (x-7)=18cm]]> 2021-06-14 23:08:35 UTC https://padlet.com/mintjemanenggek1/vw3lrkqrptozki5a/wish/1606159690 Adnan fairus syahrul 7b https://padlet.com/mintjemanenggek1/vw3lrkqrptozki5a/wish/1606925643 1.a. -30 + 5x = -5
= 5x = 25
x = 25 : 5 = 5

b. 5x + 24 = -6 - 4x
= 9x = -30
x = -30/9 = 3 1/3

2. bilangan genap 2n
= 2n + (2n + 2) + (2n + 4)
= 6n + 6 = 90
= 6n = 90-6
n = 84/6 = 14
Bilangan terkecil = 2n = 2(14)=
= 28
Bilangan terbesar = 2n + 4
= 2 (14) + 4
= 32
Jadi jumblah bilangan terkecil dan terbesar adalah : 28 + 32 = 60= 28
Bilangan terbesar = 2n + 4
= 2 (14) + 4
= 32
Jadi jumblah bilangan terkecil dan terbesar adalah : 28 + 32 = 60
3.dik : panjang = x
lebar = x -7
k : 86 cm

penyelesaian :
K = 2(P+L)
= 86 = 2 (x+x-7)
= 86 = 2 ( 2x - 7 )
= 86 = 4x - 14
= 86 + 14 = 4x - 14 + 14
= 100 = 4x
= 1/4 X 100 = 1/4 X 4x
25 =x

Jadi panjang : (x) 25 cm
Lebar (x-7) 18 cm]]> 2021-06-15 06:44:34 UTC https://padlet.com/mintjemanenggek1/vw3lrkqrptozki5a/wish/1606925643 RAFA FATKHUR RAHMAN 7B https://padlet.com/mintjemanenggek1/vw3lrkqrptozki5a/wish/1613553250
1. A. -30 + 5x = -5
= 5x = 30 -5
= 5x = 25
= x = 25 / 5 = 5
B. 5x + 24 = - 6 – 4x
= 5x + 4x = -6 - 24
= 9x = -30
= x = 3 1/3

2. Bilangan genap = a
3 bilangan genap berurutan = a + (a + 2) + (a + 4) = 90
3a + 6 = 90
3a = 90 - 6
3a = 84
a = 84 / 3
a = 28
Jadi bilangan genap terkecil adalah a = 28
Bilangan genap terbesar adalah a + 4 = 28 + 4 = 32
Jadi jumlah bilangan genap terkecil dan terbesar adalah
28 + 32 = 60

3. Keliling persegi panjang =
2p + 2l
l = p - 7
keliling = 86

2p + 2l = 86
2p + 2 (p - 7) = 86
2p + 2p -14 = 86
2p + 2p = 86 + 14
4p = 100
p = 25

Jadi lebarnya
l = p - 7
l = 25 - 7
l = 18
Jadi lebarnya 18 meter]]> 2021-06-18 02:54:32 UTC https://padlet.com/mintjemanenggek1/vw3lrkqrptozki5a/wish/1613553250
