Question

1.hitunglah perkalian berikut dengan cara nya
a. -7 x -8 =
b. 10 x (-12) =
c. -9 x (-10) =
d. -8 x (-4) x (-9) =

2.Tentukan Pengganti P supaya benar
a.p x (-6) = -54
b.-4 x 12 x p = 144

3.Hitunglah hasil pembagian berikut
a.72 : (-6) =
b. [ 90 : (-15) : -3 ] =
c. -7 x (-15) : [ 5 + (-26) ] =
d. -96 : (-16) =

4.Jika P = -24
Q = 12
R = -6
Tentukan nilai dari = a.P x Q : Q + R
b P + R : R - Q

Nomor 1,3,4 pake cara,yang udah jawab makasih banyak yaa!

Answer 1

1.
a.-7×-8=56
b.10×(-12)=-120
c.-9×(-10)=90
d.-8×(-4)×(-9)=32×(-9)=-288

2.
b.p x (-6)=-54
p = 9
c.-4 × 12 × p = 144
= -48 x p
p = 3

3.
a.72 : (-6) = -12
b. (90 : (-15)) : (-3) = 6 : (-3) = -2
c.------------
d.-96 : (-16) = 6

4.
a.-24 × 12 : 12 + -6 = -288 : 12 + -6 = -24 + -6 = -30
b.-24 + -6 : -6 - 12 = -24 + 1 - 12 = -23 - 12 = -35

Sorry banget ya , kalau salah ☺

Answer 2

1
a. 56
b. -120
c 90
d.-288

2.
a. p×(-6)=-54
p=-54/-6=9

b.-4×12×p=144
p=144/12 ÷-4
=12÷-4
=-3
3.
a.-12
b. [-6:-3]=-2
c. -7×(-15):[5+(-26)]
=7×(-15):[-21]
= (-105):(-21]
=5
d. 6

4
a.p×q:q+r
=-24×12:12+(-6)
=-24×1+(-6)
=-24+(-6)
=-30
b. p+r:r-Q=
=-24+(-6)÷(-6)-12
=-24+1-12
=-23-12
=-35
