By a 6th grader-----------------------------------------------------------------------------------------------find # that is a common multiple of 2 and 7 - the denominators ( 14 )
then do:
denominator stays same - if improper fraction change to mixed #
1 times 7 = 7 + 3 times 2 = 6
2 times 7 = 14 7 times 2 = 14
6 + 7 over 14 is 13 over
14
if possible and needed - change to simplest form

Answer:
CD = 14
Step-by-step explanation:
<em>here</em><em>'s</em><em> </em><em>your</em><em> </em><em>solu</em><em>tion</em>
<em> </em><em> </em>=> In ∆ ABD and ∆ CBD
=> AB = CB
=> Angle ABD = Angle CBD
=> DB = DB
=> hence, both triangle are congurent
By ASA (criteria)
=> so, AD = CD (by C.P.C.T)
=> CD = 14
=> AD = 14

Answer:
23.6°
Step-by-step explanation:
In this question we have to use some trigonometry to work out angle XVW. Since we are working out angles all of the trigonometric functions will have to be to the ⁻¹. The first thing we need to identify is will formula will we use out of the following:
Sin⁻¹ = Opposite ÷ Hypotenuse
Tan⁻¹ = Opposite ÷ Adjacent
Cos⁻¹ = Adjacent ÷ Hypotenuse
-------------------------------------------------------------------------------------------------------
10 = Hypotenuse
4 = Opposite
-------------------------------------------------------------------------------------------------------
We know which formula to use because the length won't be in the triangle for example we will be using the Sin triangle because we don't have an adjacent. If we don't have an adjacent then the other formula's won't work.
Now we substitute in the values to find the value of angle XVW
Sin⁻¹ = Opposite ÷ Hypotenuse
Sin⁻¹ = 4 ÷ 10
The value of angle XVW is 23.57817848
Answer:
7 dollars
Step-by-step explanation:
To solve, use this equation:
34.20 - (16 x 1.70) = x
First do 16 x 1.70
This equals 27.2
34.20 - 27.2 = x
Now subtract
34.20 - 27.20 = $7
