Answer:
Olivia typed speed per minutes is 54 words
Step-by-step explanation:
Given:
Olivia typed 36 word in 2/3
Solution:
By Unitary method, calculate the speed of typing by Olivia as-
2/3 Minutes → 36 Words
1 Minutes → 36 ÷(2/3) Words
1 Minutes → 36x3÷2 Words
1 Minutes → 54 Words
Therefore Olivia typed speed is 54 word.
Answer:
9 times 5 + c
Step-by-step explanation:
1. P = IRT....for T
P / (IR) = T
2. A = 2(L + W)....for W
A/2 = L + W
(A/2) - L = W
3. y = 5x - 6...for x
y + 6 = 5x
1/5y + 6/5 = x....or (y + 6)/5 = x
4. 2x - 3y = 8....for y
-3y = -2x + 8
y = 2/3x - 8/3
5. not exactly sure of the equation here.....(x + y) / 3 = 5 ?? or 3(x + y) = 5 ??
6. y = mx + b....for b
y - mx = b
7. ax + by = c....for y
by = c - ax
y = (c - ax)/b...or y = (c/b) - (ax/b)
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
