Answer:
x = -9
Step-by-step explanation:
- 2(x + 7) = 4
Distribute
-2x -14 = 4
Add 14 to each side
-2x-14+14 = 4+14
-2x = 18
Divide each side by -2
-2x/-2 = 18/-2
x = -9
Value=amount times cost per unit
paper=10 times 0.55
pencils=6 times 0.75
she bought 10 paper and 6 pencils
cost=10*0.55+6*0.75=$10.00 total
The probability of picking a green grape is 1/2.
<h3>What is probability?</h3>
Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1.
Since the probability of picking a red grape out of the bowl, eating it, and then picking a green grape out of the bowl is 1/8 and probability of picking just a red grape is 1/4 .
The probability of green grape will be the division. This will be:
= P(R and G) / P(R)
= 1/8 ÷ 1/4
= 1/8 × 4/1
= 1/2
The probability is 1/2.
