Think of improper fractions as top heavy. If the numerator is lager than the denominator, then you have an improper fraction. Ex: 12/6 = 2 because 6 goes into 12, two times. Mixed numbers can turn into improper fractions. Ex: 7 2/3 = 23/3 which divides back down to 7 2/3. To create improper fractions from mixed number you multiply the denominator by the whole number and add the numerator to the product of the whole number and denominator. ( 3*7=21+2=23) and you just keep the same denominator to then divide. 23/3 = 7 2/3

im bored
Step-by-step explanation:
I supposed you mean add the equation h + 3 to 6h + 1?
6h + 1 + h + 3 = 7h + 4
But if you mean subtract the equation h + 3 from 6h + 1
6h + 1 - (h + 3) = 6h + 1 - h - 3 = 5h - 2
2 - 3d = 4d - 19
Add the opposite to both sides to get the variable on the left side only.
2 - 3d = 4d - 19
-4d -4d
2 - 7d = - 19
Then get the terms w/o variables on the right,
2 - 7d = - 19
-2 -2
-7d = -21
Then divide by the number paired with the variable.
--7d = -21
----- ----- ; d = 3
-7 -7
Final answer = 3
Hope I helped :)
Answer:
Part 1)
Part 2)
Part 3)
Part 4)
Step-by-step explanation:
step 1
Find the length side c
Applying the Pythagoras Theorem
substitute the given values
step 2
Fin the measure of angle B
we know that
In the right triangle
substitute the given values
step 3
Find the measure of angle A
we know that
The measure of interior angles in a triangle must be equal to 180 degrees
so
∠A+∠B+∠C=180°
Remember that in a right triangle the measure of angle C is 90 degrees
we have
substitute
