y=15
5y-20=2y+25 move terms
5y-2y = 25+20 calculate like terms
3y=45 divide both sides by 3
Answer:
96
Step-by-step explanation:
Total number of people attending the history museum is 200
Surveyed people are 25
Out of the 25, 12 people said yes
Therefore; the fraction which said yes = 12/25
To find the total number of people expected to say yes out of those that attended the history museum;
Fraction of the sampled that said yes × total number of people that attended.
= 12/25 × 200
= 96
Ok, the perimeter of the rectangle is 40 inches.
To determine which values of x we would use for creating a graph of a parabola, we need to know where the line of symmetry, or the axis of symmetry is. For that we can use the equation:
y=(x-h)+k, where we know h and k.
From this equation we can see that the line of symmetry is passing trough x=h.
And now we can determine which values do we need to add to h and to subtract from h to get values of x to create the table of values to plot a parabola.
