Answer:
5,0967,358
Step-by-step explanation:
Answer: The system of equations represents the constraints in this situation are:
s + h = 40
$18s + $14h = $700
The above equations are known as simultaneous equations. 40 scarves and hats were sold, this can be represented with this equation:
number of hats sold + number of scarves sold = 40
s + h = 40
The total amount made from the sales is the sum of the total amount made from the sale of the hats and the total amount made from the sale of the scarves. This can be represented with this equation:
($18 x s) + ($14 x h) = $700

Answer:
10.5
Step-by-step explanation:
ΔXYZ is similar to ΔABC. So the corresponding sides are proportional:
XY / AB = XZ / AC = YZ / BC
We want to find length AB, so we can either use the first proportion:
7 / k = 3 / 4.5
Or we can use the second proportion:
7 / k = 6 / 9
Either way, we'll get the same answer. I'll use the second proportion. Cross multiplying:
6k = 63
Dividing:
k = 10.5
Answer:
it seems that the answer didn't match the alternatives. But t < 1 is true.
If t > 1:
So, considering t = 2
This is not true.
Step-by-step explanation:
Given inequality:
Dividing both sides by -7 will led to the flip of the inequality symbol.
Considering t = -1
That's right
