x + 14 = 7x + 32 - 3x

Answers

Answer 1

Answer:

-6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x+14=7x+32−3x

x+14=7x+32+−3x

x+14=(7x+−3x)+(32)(Combine Like Terms)

x+14=4x+32

x+14=4x+32

Step 2: Subtract 4x from both sides.

x+14−4x=4x+32−4x

−3x+14=32

Step 3: Subtract 14 from both sides.

−3x+14−14=32−14

−3x=18

Step 4: Divide both sides by -3.

−3x/−3=18/−3

x=−6

If represents the number of bacteria in a culture at time t, how many will there be at time

Answers

Answer:

Population of bacteria at  time [tex]t = 6[/tex] is [tex]2441[/tex]

Step-by-step explanation:

The complete question is

If [tex]y = 10 (2.5)^t[/tex]represents the number of bacteria in a culture at time t, how many will there be at time [tex]t = 6[/tex]

Solution

Given

The population of bacteria after time t is equal to [tex]y = 10 (2.5)^t[/tex]

Population when at time [tex]t = 6[/tex]

We will substitute the value of time in above equation.

[tex]y = 10 (2.5)^6\\y = 10 *244.14\\y = 2441.4 = 2441[/tex]

justine and her cousin natalie are picking out snacks at the corner store for movie night. natalie spends $5.30. justine spends 1 1/3 times as much as natalie. how much money do the girls spend in all?

Answers

Answer:

$12.35

Step-by-step explanation:

to figure out how much justine spends we need to multiply 1  1/3 with 5.30

1  1/3=4/3

4/3=1.33(decimal for easy calculations)

1.33*5.30=7.05

so now to figure out how much BOTH the girls spend:

7.05+5.30=12.35

$12.35
