Hey there!
Tom's age to Mary's is 3:4; an equivalent ratio is 15:x (x symbolizes Mary's age).
To solve for this, we need to divide our proportions. By that, I mean divide Tom's older age by his younger age. If we do so, we should get a scale factor that we can multiply Mary's younger age by.
15 / 3 = 5
This means that the scale factor of the ages is 5.
x / 4 = 5 (Solving for Mary's unknown age.)
To solve for x, multiply both sides by 4.
x/4 * 4 = x
5 * 4 = 20
x = 20
Mary's age is 20.
I hope this helps!
Yes, so the Y intercept of the linear regression line is 250 ( it is on the y-axis at point [0,250]. You can also see that for every 2x the number on the y axis decreases by 50. This means that the slope is -25. Now put what we know into the equation for a line - y=mx+b
y = -25x +250
Answer:
x = 5
Step-by-step explanation:
It is given that the angle below is a right angle, meaning that it is 90 degrees.
So, 8x and 50 must both add up to 90 degrees.
Let's make an equation that we can solve using this information.
8x + 50 = 90
8x = 40
x = 5

Good evening :)
4 3/4 * 5 3/8
= 19/4 * 43/8
=Multiply numerator together and denominator together
= 817/32
I hope that's help !
