1 yard = 3 feet
3 * 4 = 12
So 4 yards is equal to 12 feet.
Answer:
18.028 inches
Step-by-step explanation:
soln
a=10
b=15
c=?
now,
a^2+b^2=h^2
(10)^2+(15)^2=h^2
100+225=h^2
325=h^2
h=18.028(325's square root)
If jack sells 3 subscriptions in an hour and sue sells 5 subscriptions in an hour they will both earn $18 per hour
Let the x represent the unknown number.
"2 times a number" is 2x
"The sum of 2 times a number and 11" is 2x + 11
"The sum of 2 times a number and 11 is -7" is 2x + 11 = -7
Now we solve the equation for x to find the unknown number.
2x + 11 = -7
Subtract 11 from both sides.
2x = -18
Divide both sides by 2.
x = -9
Answer: The number is -9.
Check: 2 times -9 = -18
-18 + 11 = -7
The answer is correct.
Answer:
x = 100 degrees.
Step-by-step explanation:
We the the External Angle of a Triangle theorem:
The external angle = the sum of the 2 opposite internal angles.
x = 61 + 39
x = 100 degrees.
