Answer:
A and D
Step-by-step explanation:
4×3=12
4×d=4d
12+4d
Then;(4×d)+(3×4)=4d +12
Same expression
Answer:
<em>29 minutes more</em>
Step-by-step explanation:
Let m represent minutes
changing the statement to algebra, since the second company charges a different rate at night and weekend we have the equation below;
$19.99 + $0.35m > $29.99
Subtract 19.99 from both sides to isolate m and we have;
$19.99 -$19.99 + $0.35 > $29.99 - $19.99
= $0,35m > $10.00
Divide both side by 0.35 to obtain the value of m;
> 
= m > 28.57
<em>m ⩾ 29 minutes</em>
<em>The second company's will be twenty nine minutes or more costlier than the first company</em>
Answer:
71%
Step-by-step explanation:
Conditional Probability: <u>P(A and B)</u>
P(A)
P(A and B): 0.5
P(A): 0.7
=0.5/0.7
=0.71428... (x 100)
Answer:
Step-by-step explanation:
You need to specify what the goal of the problem is.
If Kai picked 7 times as many blueberries as Nico, then:
n + 7n + 297, or
8n = 297. Unfortunately, 8 does not divide evenly into 297, and we certainly are not interested in picking fractional blueberries.
If the problem mentioned 296 instead of 297 total blueberries, then
Nico (n) picked 47 blueberries and Kai picked 7 times that many, or 329.
X - 4 +6 -x
x - x = -2
0 = -2
No solution
