Answer:
j = 0 or j = 30
Step-by-step explanation:
j² - 30j = 0
Factorise j out of both terms on the left side.
j (j-30) = 0
Apply zero product rule.
j = 0 or j-30 = 0
Find the value of j.
j = 0 or j = 30

Answer:
The average cost of one mango = c = ₦8
Step-by-step explanation:
Let 'c' be the average cost of one mango
The original amount Idahtonye has = ₦50.00
The amount of mangoes Idahtonye buys = 6 mangoes
As he gets back the change of ₦2 after paying ₦50.00 to buy 5 mangoes.
Thus the equation becomes
50 - 2 = 6c
48 = 6c
dividing both sides by 6
48/6 = 6c/6
c = 8 ₦
Therefore, the average cost of one mango = c = ₦8
No solution.
2y-x=6 =y=1/2x+3
Since 1/2x does not equal 1/2x+3, this is a false statement and therefore has no solution
Answer:
212.5 m²
Explanation:
<u>Area of the figure</u>:
= area of the rectangle's + area of triangle's
= 6 × 9 + 7 × 4 + 1/2 × 13 × 7 + 1/2 × 10 × 17
= 85 + 54 + 45.5 + 28
= 212.5
