Answer:
x^2+2x-8= x^2+10x-8x-80 =x(x+10)-8(x+10)
=( x-8) (x+10)
therefore x= 8 or x=-10
Answer:
The solution to this question is attached below:
Answer:
a) ⅖+⅓ = 6/15 + 5/15 = 11/15
b) 5/9 - 1/2 = 10/18 - 9/18 = 1/18
Answer:
An applicant must score a minimum of 128
Step-by-step explanation:
To solve this question, we make use of the z-score formula.
Z = (X - mean)/standard deviation
Firstly, let’s list out the parameters from the question. From the question, we can deduce that:
Z = 1.5
X = ?
Mean = 110
Standard deviation =12
1.5= (X-110)/12
18 = X - 110
X = 110 + 18
X = 128
Answer:
Total need of salt = 5/3 tsp or 1.67 tsp (approx)
Step-by-step explanation:
Given:
Total number of cake = 5 cakes
Each cake need = 1/3 tsp
Find:
Total need of salt
Computation:
Total need of salt = Total number of cake x Each cake need
Total need of salt = 5 x (1/3)
Total need of salt = 5/3 tsp
Total need of salt = 5/3 tsp or 1.67 tsp (approx)
