Cost of company A=monthlyfee+text=20+0.03t where t=number of texts
A=20+0.03t
company b is monthlyfee+texts=5+0.07t
B=5+0.07t
1.
c=20+0.03t
c=5+0.07t
using c for cost is confusing because we can't tell which is for which company
2.
equal, means the costs are equal so
20+0.03t=5+0.07t
minus 5 from both sides
15+0.03t=0.07t
minus 0.03t from both sides
15=0.04t
divide both sides by 0.04
375=t
the answer is 375 texts
Answer:
a) How many full packages will be used to ship the jeans?
41 packages
b) How many jeans are left over?
24 Jeans
Step-by-step explanation:
We are told that a manufacturer: made 1500 Jeans and is shipping them in packages of 36.
Hence, the number of packages of 36 he can send out to stores is calculated as:
1500÷ 36
= 41.666666667
In whole number packages = 41 packages
Hence, 41 full packages would be used to ship the jeans.
The number of Jeans left behind is
1500 - (41 × 36)
= 1500 - 1476
= 24 Jeans
It is in y intercept form
y = mx + b
where b is the y intercept
y = 3/4 x + 2
so b = 2
therefore the y intercept is 2
Answer: They are parallel so there is no solution.
Step-by-step explanation:
Brayden- y=5x-1 or y-5x= -1
Howard- y=5x+1 or y-5x= 1
Vincent- y=4x+5 or y-4x= 5
In summary, they are all parallel so there is no solution.
We need to leave m alone on the right hand side, so let's move everything else to the left hand side.
First of all, we can subtract b from both sides to get
Now, we can divide both sides by c to get
And so we solved the expression for m, because we have written an expression in the form 
, where the right hand side doesn't depend on m.
