Lan is 146 centimeters tall now.
<u><em>Explanation</em></u>
Let, Lan's current height is 
centimeters
As Lisa is 6 centimeters taller than Lan and Lan is 10 centimeters taller than Jim, so Lisa's current height = 
centimeters and Jim's current height = 
centimeters.
Every month, their heights increase by 2 centimeters.
So, after 5 months.....
Lan's height = 
centimeters,
Lisa's height = 
centimeters and
Jim's height = 
centimeters
Given that, the sum of Ian's and Jim's heights will be 140 centimeters more than Lisa's height in 5 months. So the equation will be....
So, the current height of Lan is 146 centimeters.
Answer:
slope is -3
y intercept is 2
Step-by-step explanation:
3x+y=2 [subtract 3x from both sides]
y=-3x+2
slope is -3
y intercept is 2
Answer:
The approximate length of the missing side is of 5.57 cm.
Step-by-step explanation:
Pythagorean Theorem:
In a right triangle with sides a and b and hypotenuse c, the Pythagorean theorem states that:
In this question:
We want to find b. Then
The approximate length of the missing side is of 5.57 cm.
4x - 3y = 16
x + y = -3
Subtract y from both sides of the 2nd equation.
x = -3 - y
Now that we have a value of x, we can plug it into the first equation to solve for y.
4(-3 - y) - 3y = 16
Distributive property.
-12 - 4y - 3y = 16
Combine like terms.
-12 - 7y = 16
Add 12 to both sides.
-7y = 28
Divide both sides by -7.
y = -4
The value of y is -4, and now we can solve for the value of x.
Plug this value into either equation.
x + (-4) = -3
Add 4 to both sides.
x = 1
The value of x is 1.
<h3>x = 1</h3><h3>y = -4</h3>
The radius of a circleis part of the circumference formula: C = 2 pi r.
So we rearrange the formula: r = c/2 pi.
Now we have to figure out the circumference. If the outside of the circle is 12 cm for 17degrees, then17 degrees x what is 360 degrees? 360 divided by 17 is 21.2. So the 12 cm should be multiplied by 21.2, to give 254.1cm. This is our circumference.
Now we do r = 254/2 pi.
r = 40.46cm.
