Answer:

-9 - 8x

Step-by-step explanation:

Andy multiplied incorrectly it should have been -4*2x, -4*-3

Sylvie forgot to multiply both sides she did -4*2x but forgot to do -4*-3

Decrease 700kg by 25% <br> (With working out)

Natali5045456 [20]

Answer: 525kg

Step-by-step explanation:

To decrease 700kg by 25% implies

700 - 25% of 700kg

25% of 700 = 25/100 × 700kg

0.25 x 700

= 175

Therefore, to decrease 700kg by 25%, since 25% is 175kg, we subtract 175kg from 700kg

700kg - 125kg

= 525kg
