Answer:
C
Step-by-step explanation:
Enjoli needs 45 cupcakes for the party
The recipe makes 15 cupcakes
So Enjoli needs three times what the recipe produces
Lets form an expression for number of cupcakes produced by the recipe;
1 batches + 1.5 strawberries= 15 cupcakes---------multiply by 3 to get Enjoli's
3batches + 4.5 strawberries= 45 cupcakes
From the graph, it is point C
4 x
5 20
80/5=16
20(total questions)/5(total questions, simplified)=4
Multiply 4 by 4(correct questions).
The second method is better for a student in elementary!
Answer:
x²-2x-35
Step-by-step explanation:
Write it in factored form
(x+5)(x-7)
multiply them to get
x²-2x-35
Answer:120in
Step-by-step explanation:
- How can you write a system of equations to model this situation?
Let y = <span>your pay </span>
<span> x = deliveries
</span>
Your equations would be written as:
<span>y=9.50*4 </span>
<span>y=2*4+3x </span>
- Which method should you sue to solve the system?
Substitution method
- How can you interpret the solution in the context of the problem
Substituting y for 9.50*4:
<span>9.50*4 = 2*4 + 3x </span>
<span>Simplifying: </span>
<span>38=8+3x </span>
<span>Solving: </span>
<span>30=3x </span>
<span>x=10
</span>
<span>Therefore, you need 10 deliveries to get the same pay as the competitor.</span>
