Answer: Lcm=60
Step-by-step explanation: but if you want lcf its always 1
Answer:
54 is x
Step-by-step explanation:
Sounds like you describing vertical angles. Vertical angles are congruent so that means 2x+2=3x-52
2=1x-52. Subtracted 2x on both sides
54=1x. Added 52 on both sides
54=x. Since 1 times x is x
- 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>
X = -2 + y
-16x - 3y = -25
Let's substitute x into the second equation, since the first equation already tells us what x is.
Multiply -16 by x, which is (-2 + y)
-16(-2 + y) -3y = -25
Simplify.
32 -16y -3y = -25
Simplify. Get the variable on one side.
-19y = -57
Divide both sides by -19 to solve for the variable.
y = 3
Now plug y = 3 into one of the equations to find x. I'll use the first equation, since it's easier.
x = -2 + y
x = -2 + 3
x = 1
The answer is x= 1, y =3, which may be written as (1, 3). Hope this helps.
The distributive property of multiplication is a very useful property that lets you rewrite expressions in which you are multiplying a number by a sum or difference.
