4z ≥ 7
divide seven by four
z ≥ 1.75
or, if you need it in fraction form, it would be
z ≥ 7/4
-96 divided by -8 = 12
Negative and negative make a positive, therefore the x has to be a positive for the answer to be a negative (-96)
Since you're looking for the product, you divide the two numbers you have.
We are given the general formula of the curve of y = ax2 + bx + c. The tangen line at the origin is y = 4x. This eliminates the second term in which the derivative should be reflected as a constant. Since when the derivative of the first term is 4x, then a should be 2. From the points, c should be equal to 24.
Answer:
Let the unit of ratio be a.Then,the divided parts will be 3a,5a,4a and a.
A/q,
=>3a+5a+4a + a = 182.
=>13a = 182
=>a = 182/13
=>a = 14.
Hence,the smallest part = 14
Answer:
20 mangoes.
Step-by-step explanation:
Given:
Total number of mangoes, a trader bought = 
A trader bought at the rate of 4 mangoes for 10 naira.
Five of the mangoes were bad.
He sold the remaining at the rate of 5 mangoes for 20 naira.
He made a gain of 10 naira
Question asked:
Total number of mangoes, a trader bought =
= ?
Solution:
Unitary method
Cost price of 4 mangoes = 10 naira.
Cost price of 1 mango = 
Cost price of
mango = 
As 5 of the mangoes were bad and he sold the remaining mangoes, then Total number of mangoes sold = 
Sale price of 5 mangoes = 20 naira
Sale price of 1 mango = 
Sale price
of mango = 
Now, as we know,



Adding both sides by 20

Multiplying both sides by 2

Dividing both sides by 3

Therefore, total number of mangoes, a trader bought is 20.
