Answer:
x=7
Step-by-step explanation:
6x-7 and 4x+7 are vertical angles and are thus equal. Then 6x-7 = 4x+7, or 2x = 14.
x = 7.
Answer: To check a solution, you can substitute the solutions into the equations and verify that both equations are true.
Step-by-step explanation:
To answer this, we need to first find the rate and the multiply it by 3. 840/12 = 70 miles per hour. Then multiply it by 3. 70*3=210 miles. Another way we can do it is that we can divide 840 by 4 because 12 hours / 4 = 3 hours. 840/4 = 210 miles.
Answer:
Distance = 110.5 cm
Step-by-step explanation:
It is given that,
The basement floor is at an elevation of −10.5 feet
The second story floor has an elevation of 121 feet.
We need to find the distance between the basement floor and the second story floor.
Distance = -10.5 + 121
= 110.5 feet
So, the distance between the basement floor and the second story floor is 110.5 cm.
Step-by-step explanation:
First draw a straight line
then mark a point A on the line
after take the compass and take 10 cm size
then keep the compass on A and draw the arc its B
then keep the point on B and draw arc to A
next keep the compass on A draw arc on same length
to upside to line do same thing from point B to upside
mark a point meeting borth arcs its c
all ABC triangle
