The answer is c because you need to add 4 to both sides to cancel it out. Then you divide by 7 on both sides to get x by itself and reveal the answer.

Answer:

x = 137

Step-by-step explanation:

Step-by-step explanation:

∠43° and ∠x° are same side exterior angles as they are on the same side as the transversal but outside the parallel lines. The 2 angles are supplementary, hence

x + 43 = 180 ( subtract 43 from both sides )

x = 137

Two numbers have a sum of 761 and a difference of 335.what are the 2 numbers ​
melisa1 [442]

Answer:

548 and 213

Step-by-step explanation:

Use a linear function:

Let x = 1st number

Let y = 2nd number

x+y=761

x-y=335

2x=1096

x=548

plug x into either equation

548+y=761

y=761-548

y=213

548-y=335

-y=-213

y=213

Riley paid $2.99 for a 20-ounce container of soup. at that rate, what would riley pay for a 12-ounce container of the same soup?
love history [14]
$2.99/20 will be the unit price of soup. Then the amount Riley has to pay for 12 ounce would be 12*2.99/20=$1.794

Tritium is a radioactive isotope of hydrogen that decays by about 5% per year. A large bottle of water that contained 450,000 tr
Basile [38]

Using an exponential function, it is found that the bottle contains 255,960 atoms of tritium after 11 years.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem:

  • The bottle initially contained 450,000 tritium atoms, hence A(0) = 450000.
  • The amount decays by about 5% per year, hence r = 0.05.

Thus, the equation is given by:

A(t) = A(0)(1 - r)^t

A(t) = 450000(1 - 0.05)^t

A(t) = 450000(0.95)^t

After 11 years, the amount is given by:

A(11) = 450000(0.95)^{11} = 255960

The bottle contains 255,960 atoms of tritium after 11 years.
