Funke, Adamu, Shehu, Kwame and Tanko play a game of cards. Funke says to Adamu, "If you give me 5 cards, you will have as many a
baherus [9]

This involves basic arithmetic calculations and simultaneous equations.

Adamu has 25 Cards

Let the following letters represent the number of cards each has;

A: ADAMU

F: FUNKE

S: SHEHU

K: KWAME

T: TANKO

  • If adamu gives funke 5 cards, he will have as many as tanko. Thus;

A - 5 = T  --- eq 1

  • If funke gives adamu 4 cards, he will have as many as kwame. Thus;

A + 4 = K  --- eq 2

  • Funke and adamu have a total of 13 more cards than the total that kwame and tanko have. Thus;

A + F = K + T + 13   --- eq 3

  • Adamu has 2 cards more than what Shehu has. Thus;

A - 2 = S  --- eq 4

From online research, the Total Number of cards is 134 and not 133. Thus;

A + F + K + S + T = 134  --- eq 5

Let's put A - 5 = T and A + 4 = K in eq 3 to get;

A + F = (A + 4) + (A - 5) + 13

A + F = 2A + 12

F = 2A - A + 12

F = A + 12

Let's put A - 2 = S ; F = A + 12 ; A - 5 = T and A + 4 = K into eq 5 to get;

A + A + 12  + A + 4 + A - 2 + A - 5 = 134

Simplifying gives;

5A + 9 = 134

5A = 134 - 9

5A = 125

A = 125/5

A = 25

Adamu has 25 Cards

3 added to 5 times a number and the result is multiplied by 4. The final result is 72. Find the number
Readme [11.4K]
Hmm... I would say the equation would look like 3+5x=72/4. 
3+5x=72/4
3+5x=18
5x=18-3
5x=15
x=15/5
x=3

The number is 3

Vinil7 [7]

Answer:

∠MNP is your answer

Step-by-step explanation:

Note the angle and the order it is said. It is ∠ABC, which means the double line side, one curve line angle, and then triple line side.

Now look at the second triangle, the same double line side (NM), one curve line angle (∠N), and triple line side (NP)

Put them together: ∠MNP is your answer
