20p - 8p = 12p
First, calculate the total cost of eight buttons at 9p each: 8 buttons × 9p = 72p. Then, determine the total amount from four 20p coins: 4 × 20p = 80p. Finally, subtract the cost of the buttons from the total amount: 80p - 72p = 8p. You would have 8p left after the purchase.
To find how much more than 50p the sum of 8p, 18p, and 28p is, first calculate the total: 8p + 18p + 28p = 54p. Next, subtract 50p from 54p: 54p - 50p = 4p. Therefore, the sum is 4p more than 50p.
13 of 20p = 260p.
8p+5 = 11+7p= 8p-7p = 11-5p = 6
8p - 3 = 13 add 3 to both sides 8p = 16 divide by 8 to both sides p = 2
20p
Use 50p, 20p, 20p, 5p and two 2p coins.
First, calculate the total cost of eight buttons at 9p each: 8 buttons × 9p = 72p. Then, determine the total amount from four 20p coins: 4 × 20p = 80p. Finally, subtract the cost of the buttons from the total amount: 80p - 72p = 8p. You would have 8p left after the purchase.
-8p + 3 = -29 8p - 3 = 29 8p = 29 + 3 8p = 32 p = 32/8 p = 4
To find how much more than 50p the sum of 8p, 18p, and 28p is, first calculate the total: 8p + 18p + 28p = 54p. Next, subtract 50p from 54p: 54p - 50p = 4p. Therefore, the sum is 4p more than 50p.
-8 = -8p + 4Add 8p to each side:8p - 8 = 4Add 8 to each side:8p = 12Divide each side by 8:p = 1.5
