Aaron is building a brick wall. The wall will need 1025 bricks. the weight of each brick is 2.89 kg. Aaron will pay a delivery charge if the total weight of bricks is over 2500kg

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
