Can someone help me find x ?
ivolga24 [154]

Answer:

x = 15

Step-by-step explanation:

Apply the keg rule to find x. The keg rule is given as:

Hypotenuse / leg = leg / part of the hypotenuse directly under the leg

Hypotenuse = 25

Leg = x

Part of the hypotenuse directly under the leg = 25 - 16 = 9

Plug in the values

25/x = x/9

Cross multiply

x*x = 25*9

x² = 225

x = √225

x = 15

Frank has a 2-digit number on his baseball uniform. The number is a multiple of 10 and has 3 for one its factors. What three num
umka2103 [35]
2 digits number

x <100   because 2digit

x/10  ∈ { 1, 2, 3, 4, 5, 6, 7, 8, 9}

x/3  ∈ {1, 2, 3, 4, 5, 6, 7, 8, 9 }

max number divide by 10 is 90
max number divided by 3 is 99

because we know that numer is divided by 10 so our collections looks like:

{10, 20, 30, 40, 50, 60, 70, 80, 90}

we look from this collections only numbers witch will divided by 3:

30, 60, 90 = this is solutions

a) we need a natural number divided by 3 and 10 lower than 100
b) i need to use lenght of number and what numbers divides them
c) as above
d) baseball, 3 and 10, 3, 30,60,90

ruslelena [56]

20 = LW

To know the length for various measurement of the width, we can write it by:

L = 20 / W

You can substitute any measurement to W and you can obtain the corresponding value of the length.

2 Solve the equation for t. Show your work.<br> 5(2t - 3) – 7.5t = 0.5(12 – t)<br> PLEASEEEE HELP ME
dsp73

Answer:

t = 7

Step-by-step explanation:

5(2t - 3) – 7.5t = 0.5(12 – t)

5*2t - 3*5 - 7.5t = 12*0.5 - t *0.5

10t - 15 - 7.5t = 6 - 0.5t           {Now, combine like terms}

10t - 7.5t - 15 = 6 - 0.5t

         2.5t -15 = 6 - 0.5t      {Add 15 to both sides}    

         2.5t      = 6 - 0.5t + 15

              2.5t = 21 - 0.5t       { Add 0.5t to both sides}

    2.5t + 0.5t = 21  

                 3t = 21     {Divide both sides by 3}

                   t = 21/3

t = 7
