When you multiply 8 times 2 its 16 and 40-16 is 24
40-D
less than is towards the negatives and for less than or greater than you use open circles
Answer:
look below
Step-by-step explanation:
The probability of each of the cards can be found by dividing each of them by the sum of all the numbers:
P of picking card with star:
25/50=0.5
Card with square:
15/50=3/10=0.3
Card with circle: 10/50=1/5=0.2
We can then put these values into parts a,b,c, and d:
a) 3/10 chance or 30%
b) 1/5 chance or 20%
c) 1/2+1/5=7/10 chance or 70%
d) 1-0.3-0.2=1/2 chance or 50%
Answer:
x = - 9, x = 10
Step-by-step explanation:
Given
x² - x - 90 = 0
Consider the factors of the constant term (- 90) which sum to give the coefficient of the x- term (- 1)
The factors are - 10 and + 9, since
- 10 × 9 = - 90 and - 10 + 9 = - 1 , thus
(x - 10)(x + 9) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 10 = 0 ⇒ x = 10
x + 9 = 0 ⇒ x = - 9
lesser x = - 9
greater x = 10
Answer:
x = 10
Step-by-step explanation:
I'm not entirely sure what you're asking, however we know that:
5x-6=44
5x must be 50, as 50-6=44
50 divided by 5 is 10, so 10x
