Answer:
To check if a given value is a solution to an equation:
Evaluate the left-hand side expression at the given value to get a number.
Evaluate the right-hand side expression at the given value to get a number.
See if the numbers match.
240 = 16x is about an equation but you can make it more complicated by adding unneeded parts for example 240 = 16x - 81 + ((15x) + 15) - (x^2 / 2) - 45 - 1.5.
Answer:
3x²(x - 2)(x + 5)
Step-by-step explanation:
Step 1: Factor GCF
3x²(x² + 3x - 10)
Step 2: Factor Quadratic
3x²(x - 2)(x + 5)
Hi there!
To solve this problem, we need to find the amount of classmates out of the entire class who did not choose blue as their favorite color and then convert it into a percentage.
First, let's find the fraction:
Since there are 25 total people in her class, since
6 + 9 + 10 = 25
25 is the denominator of the fraction;
Since there are 16 people who did not choose blue,
6 + 10 = 16
16 is the numerator of the fraction.
So, our fraction is 16/25.
Now, we need to convert it into a percentage. To do this, we need to make the denominator 100 by multiplying it by a certain number, and then multiplying the numerator by that same number so the fraction stays equal:
16/25
= 16*4/25*4
= 64/100
= 64%
So, the answer is 64% of Stephanie's classmates.
Hope this helps!
Answer:
r=20
Step-by-step explanation:
since the angle and sum of a straight line is equal to 180, you structure an equation:
180=105+(4r-5)
solve for r
180=100+4r
80=4r
20=r
check answer
4r-5 4(20)-5
80-5
75+105=180
