\bold{Answer}

\boxed{\bold{X \ = \ 65}}

\bold{Explanation}

  • \bold{Find \ X: \ 145=\left(2x+15\right)}

\bold{----------------------}

\bold{The \ Two \ Angles \ Are \ Symmetrical. \ Since\ One \ Side \ Is \ 145 \ Degrees, \ So \ Is \ The \ Other}

  • \bold{Write \ An \ Equation}

\bold{Equation: \ 145 \ = \ (2x \ + \ 15)}

  • \bold{Solve}

  • \bold{Switch \ Sides}

\bold{\left(2x+15\right)=145}

\bold{2x+15=145}

  • \bold{Subtract \ 15 \ From \ Both \ Sides}

\bold{2x+15-15=145-15}

  • \bold{Simplify}

\bold{2x=130}

  • \bold{Divide \ Both \ Sides \ By \ 2}

\bold{\frac{2x}{2}=\frac{130}{2}}

  • \bold{Simplify}

\bold{X \ = \ 65}

\boxed{\bold{Eclipsed}}

One number is 44 times a first number. a third number is 100 more than the first number. if the sum of the three numbers is 5385
svlad2 [7]

I take it that the actual total is 538. If it really is 538538 leave me a note.

Let the first number = x

Let the second # = 44x

Let the third # = 100x

Equation

x + 44x + 100x = 538 Add the left side. All terms are part of the total.

145x = 538 Div By 145

x = 538/145

x = 3.71

Check

First number = 3.71

Second # = 44*3.71 = 163.24

Third number = 100*3.71 = 371

Total these 3 numbers 537.95 The very tiny difference is due to rounding.

Element X is a radioactive isotope such that every 61 years, its mass decreases by half. Given that the initial mass of a sample
Sever21 [200]

Answer:

27.3

Step-by-step explanation:

y=a(1/2)^t/h

Plug in

22=30(1/2)^t/61

Divide both sides by 30

0.7333333333=(1/2)^t/61

Log both

Log(0.7333333333) / Log(1/2)

0.447458977 = t/61

0.447458977 x 61 = t

27.2949976 to the nearest tenth is 27.3 = t

Reggie has $36.40 in nickels and $36.40 in dimes. What is the ratio of the number of nickels to the number of dimes that Reggie
Dmitry [639]

D 2:1, because a dime is worth twice as much as a nickel

Because the question has number of nickels listed first in the ratio that makes the answer 2:1 as opposed to B 1:2. Also, two nickels equal the same amount as one dime so for every two nickels there is one dime. In this case, there are 728 nickels and 364 dimes. 728/364 = 2/1 (simplifies down to the fourth ratio given)
