Question

1. Write the mathematical expressions for the following statements:
(i) The sum of twice x and 4 is 24.
(ii) 3 subtracted from 4x is 9.
(iii) The number - divided by 7 gives 63. (iv) 4 taken away from one-fourth of p gives 10,
(v) If we add 6 to 6 times y we get 42.
(vi) If we take 7 from 4 times y we get 21.
(vii) 2x subtracted from 44 gives 10.
(viii) 7 added to 4 times z gives 37.
2. Write the statement for the following:
(i) 2p + 5 = 15
(ii) m - 10 = 50 (iii) 2m - 10 = 40 (iv) 3z = 21

ok

Step-by-step explanation:

sorry l dont know this question answer friend

Answer 2

x+X+4=24

3-4×=9

(-)/7=68

4-1/4p=7

6+6=42

7-(4)4= 21
