How do you write an algebraic expression for the sum of a number H and 88 minus 4?

H + 88 - 4 which can be simplified to H + 84.


What is the sum of five times h and twice g is equal to 23 in equation form?

So this statement is an equation whose left side contains the sum of (5) and (twice g), and the right side contains only 23. 2g + 5 = 23

How many different combinations are possible if a coin is tossed twice and a number cube is tossed once?

18 different combinations. When a coin is tossed twice there are four possible outcomes, (H,H), (H,T), (T,H) and (T,T) considering the order in which they appear (first or second). But if we are talking of combinations of the two individual events, then the order in which they come out is not considered. So for this case the number of combinations is three: (H,H), (H,T) and (T,T). For the case of tossing a die once there are six possible events. The number of different combinations when tossing a coin twice and a die once is: 3x6 = 18 different combinations.

What is the number of possible outcomes when a coin is tossed twice?

4 : Each coin toss multiplies the generated outcome by two. The outcome for two tosses can be Heads (H) Tails (T), H H, T T or T H. As such, with three tosses the outcome can be H H H, H H T, H T H, T H H, T T H, T T T, T H T, H T T. We can define the number of outcomes as 2^n, where n is the amount of tosses.

What is the oxidation number for H2S04?

The oxidation number of H in H2SO4 is +1, the oxidation number of S is +6, and the oxidation number of O is -2. This is because the sum of the oxidation numbers in a neutral compound like H2SO4 must equal zero.
