Hey there! I'm happy to help!
Here's José's equation.
J=2a+15
And here is Nancy's.
N=3a+5
We want to find the number of animals where they are the same amount, or where J=N. We can write these equations as equal and solve for a to find the answer!
2a+15=3a+5
Subtract 15 from both sides.
2a=3a-10
Subtract 3a from both sides.
-a=-10
Divide both sides by -1.
a=10
Therefore, José and Nancy charge the same amount for 10 animals.
Have a wonderful day! :D
For this case we have the following expression:
We apply distributive property, which by definition establishes that:
So:
Answer:
Answer:
120 m
Step-by-step explanation:
Width - x
Length - 5x
x*5x = 500m²
5x² = 500 m²
x²= 500 ÷ 5
x²= 100
x = root 100
x = 10
Therefore width = 10
length 5*10 = 50
Perimeter = 2(l+w)
= 2(10 + 50)
=2*60
=120
So first let's find the cost of the grapes.
price for half a pound would be half the price. so 1.98/2 = $0.99
then let's find the price for 1.4 pounds of strawberry.
1.4*2.45 = $3.43
now add the answers and you'll get is
= $4.42
Step-by-step explanation:
Find the values of x and y to determine how many solutions.
Use the elimination method. Add both of the equations.
<u>Sum:</u>
<u />
<u>Divide each side by 3:</u>
<u />
<u />
<u>Substitute y = -(1/3) into the first equation:</u>
<u />
<u>Multiply:</u>
<u />
<u>Add 2 to both sides:</u>
-5x = 0
We can determine:
(0, -1/3)
The system of equations have 1 solution.
