Im not sure if i am understanding the question correctly...
If you are asking if Jama's mom is correct, then no. she is wrong. this is because
if you take the proportion, (is/of)=(%/100) you get (x/30)=(70/100). You then solve for x which in this case would be 21 students are wearing tennis shoes.
Hope this helps.
The correct answer is D because you cannot have a fraction as the base of a log
hope this helps :)
if you need further information just ask
Answer:4((x+3)(x-1))
Step-by-step explanation:
Factorize the common terms
4(x^2+2x-3)
Factorize
X^2+2x-3=(x+3)(x-1)
(X+3)(x-1)
4((x+3)(x-1))
Answer:
Putting the value in x = 2 , y =4 in 2x - 2y we get,
2 × 2 - 4× 2= 4-8 = -4
Putting the value in z = 3 in z - 5 we get,
z - 5 = 3 - 5 = -2
