Question

1. [-24:(-6)-7x4]:(-12) =

2. [-15x(-5)+10x(-3)]:9=

3. [ 3x (-9)+2x(-11)]x(-2)=

Jak co to x to razy . mnożenie

Answer 1

1.[-24:(-6)-7*4]:(-12)=4-28]:(-12)=-24:(-12)=2 2.(-15*(-5)+10*(-3)]:9=75-30]:9=45:9=5 3.[3*(-9)+2*(-11)]*(-2)=-27-22]*(-2)=-49*(-2)=98

Answer 2

[-24:(-6)-7x4]:(-12) = (8-24) : (-12) = -(16): (-12) = 16/12 = 1 i 4/16 = 1 i 1/4

[-15x(-5)+10x(-3)]:9= (75-30):9 = 65:9 = 7 i 2/9

[ 3x (-9)+2x(-11)]x(-2)= (-27 - 22 x 2) = -27 - 44 = -71
