Answer:
x1= -9/2 ; x2= -7/3
Step-by-step explanation:
Rewrite to 6x^2 + 27x +14x +63 = 0
Factor and get 3x(2x + 9) + 7(2x + 9) = 0
Factor again and get (2x + 9)(3x + 7) = 0
Separate into possible cases -> 2x + 9 = 0; 3x + 7 = 0
The equation has two solutions: x1 = -9/2 and x2 = -7/3
Hope this helped!!
Answer:
3240 sq meters
Step-by-step explanation:
Area of garden = 90*60= 5400 square meters.
Flowers grown on = 40%
So, grass grown on = (100 -40)% = 60%
60% of 5400 = 0.6*5400 = 3,240.
So, the area of the garden that is grass = 3,240 square meters
Answer:C) Children cannot use counters for the initial amount.
Step-by-step explanation:Problem solving allows students to use mathematical concepts, skills and the relationships among them to solve problem situations with different levels of difficulties. Problem solving framework allows students to solve mathematical situations by assisting them to handle or approach problem solving systemically.
There are basically four structures they are
(1) Join
(2) Separate
(3) Part-Part-Whole
(4) Compare.
JOIN AND SEPARATE STRUCTURES INCLUDE ACTIONS THAT INCREASE OR DECREASE A QUANTITY.
The part-part whole does not involve an action but it has a relationship between a particular whole and its two separate parts.
The compare structure also does not involve an action,but it compares two unconnected and distinct sets.
Simple interest formula:
Interest = P*R*N
P = principle amount
R = interest rate (in decimal)
N = number of time periods (in years)
Interest = 5000*0.05*4 = $1000
