The answer in a fraction is 2/5 , the answer in decimal form is 0.4 !
Answer:
x ≤ 4
Step-by-step explanation:
Solve the inequality
5x - 18 ≥ 2(4x - 15)
Expand the expression
5x - 18 ≥ 8x - 30
Rearrange the terms
5x - 8x ≥ -30 + 18
Combine like terms
-3x ≥ -30 + 18
Calculate
-3x ≥ -12
Divide both sides
x ≤ -12/-3
Calculate
x ≤ 4

Answer:
Step-by-step explanation:
Answer: x = 7 and y = -2
Step-by-step explanation:
2x +3y = 8 ----------------(1)
x-y = 9 ----------------------(2)
multiply (2) by 2
2x-2y = 18--------------------(3)
subtract (2) from (3)
-5y = 10
Divide bothside by -5
y = -2
Similarly, multiply (2) by 3
3x-3y = 27-----------------------(4)
add (1) and (4) together
5x = 35
Divide bothside by 5
x= 7
Therefore, x =7 and y= -2
If the probability of drawing a red card is 3/10, then if we take this fom a whole, 10/10, we can find the probability of not choosing a red card.
10/10-3/10=7/10
The probability of not drawing a red card is 7/10 or 70%.
