Answer:
y = 240 cm crawl
x = 120 cm walking
Step-by-step explanation:
Logic....
To do this without a calculator, it may be easier to break the number into smaller parts.
420 * 6
= (400 * 6) + (20 * 6)
= 2400 + 120
= 2520
Hope this helps! :)
Answer:

Step-by-step explanation:
The point-slope form of a line is given as:

Where
m is the slope
is the x-coordinate of the point given (passing through the line)
is the y-coordinate of the point given (passing through the line)
Now,
Given,
Slope = m = 3
= 1
= 2
Now, we simply plug these into the formula for point-slope form of a line:

This is the point-slope form.
Answer:

Step-by-step explanation:
we know that
When two lines are crossed by another line (transversal), the angles in matching corners are called Corresponding Angles.
When the line are parallel the corresponding angles are equal in measurement.
so
In this problem
-----> by corresponding angles
see the attached figure to better understand the problem
Solve for x
Subtract 50 both sides


Divide by 8 both sides
