Surprisingly, a one-step equation <em>is </em>that simple; it's just an equation that takes one step to solve. So yes, 3 + 4 = 7 would be one you could do. You could also do a simple multiplication or division problem if you'd like, for instance you could do 4*3=12, or 12/4=3. Hope I helped!
Answer:she need to do at least 3 hours of babysitting.
Step-by-step explanation:
you subtract how much she already has, 3$ from 25.50 and then you divide how much she makes in one hour of babysitting by how much money she needs so 22.50/7.50=3
so hmm the idea behind the elimination, is to make the value atop or below, of either variable, the same but with a negative sign
so hmmm say... we'll eliminate "y"
so... let's see, we have 2y and 5y, both positive
what do we multiply 2y to get a negative -5y, that way, -5y +5y = 0 and poof it goes
well let's see, let's try "k"
so.. if we multiply 2y by -5/2, we'll end up with -5y
well, let's multiply that first equation then by -5/2
so.. now we know x = 1.... so let's plug that in say hmmm 2nd equation
Answer:
50
Step-by-step explanation:
The sum of a triangle's angles are 180 so since you know one angle is 80, you would put 2x + 80 = 180, which would be 2x = 100, which simplifies to x = 50
Answer: y= -2x - 500
Step-by-step explanation:
Parallel lines have the same slopes but different y-intercepts. This means that the line parallel to y=-2x + 3 will have the same slope which is -2.
We will input the x and y coordinates for the given point into the formula and solve for the y-intercept to write the equation.
-100 = -2(-100) + b where b is the y-intercept
-100 = 400 + b
-400 -400
b = -500
The y intercept is -500 and the slope is -2 therefore, the equation will be
y= -2x - 500
