Can you walk me through the steps: 3t+2+2t-4t=3+5

Answers

Answer 1

Answer: to find t? yes.

First, you combine like terms so 3t and 2t and 4t. Add 3 and 2 and then subtract the 4. you will end up with 1t (just t) +2. you cannot add the 2 because it does not have the variable t. on the other side, you will also combine like terms. so 3+5=8. now your equation is t+2=8. this is the part where you will try to get t by itself. subtract the 2 from the left side. but in order for the equation to stay equal to itself, you have to subtract 2 from the right side as well. this will leave you with your final answer of t=6.

The density of ice is approximately 0.92 g/cm3 . If a block of ice has a volume of 2300 cm3, what is its mass?

Answers

Answer:

mass = 2116g

Step-by-step explanation:

given that

density = 0.92g/cm³

volume = 2300cm³

mass = ?

recall , the formulae for calculating the density of a substance = mass / volume

density = mass/ volume

mass = density x volume

mass = 0.92g/cm³ x 2300 cm³

mass = 2116g

therefore the mass of the substance is evaluated to be equals to 2116g

Answer:

2116g

Step-by-step explanation:

$(0.92 g)/(1 cm^3)$ = $(xg)/(2300cm^3)$

Multiply .92 by 2300 to get x

x = 2116

you download a video game on your computer. you have a 60-minute free trial of the game. it takes 5 1/6 minutes to set up the game and 7 1/3 minutes to play each level. you want it find out how many levels you can play for free.

Answers

Answer:

B. $5(1)/(6)+(7(1)/(3))l \leq 60$

Step-by-step explanation:

Given,

The time for set up the game = $5(1)/(6)$ minutes,

Also, the time for each level of game is $7(1)/(3)$ minutes,

If there are l levels of games,

Then the time taken in all levels of game = $(7(1)/(3))l$

Hence, the total time ( in minutes ) = Set up time + time in all level

= $5(1)/(6)+(7(1)/(3))l$

We have 60-minute of free trial of the game,

So, the total time taken can not be exceed to 60 minutes,

$\implies 5(1)/(6)+(7(1)/(3))l \leq 60$

Which is the required inequality.

Alrighty. The first is the quotient of a number and 3. 4. is 17n, 17 being the amount of gum he chews and n being the amount of games. 5. is easy. Since x - 16 is 14, just do the equation backwards to find x, 14+16=30. so the answer is 30. Comment the full question lf Number 6 and I will answer it.
