What is the value of t in the equation 3(2t + 5) = 5t + 25? (4 points)5

10
35

Answers

Answer:

The solution of the equation is t=10

C is correct option

Step-by-step explanation:

Given: $3(2t+5)=5t+25$

We need to solve for t

$3(2t+5)=5t+25$ (Distributive property)

Distribute 3 over the bracket (2t+5)

$6t+15=5t+25$

Move variable term left side and constant right side

$6t-5t=25-15$

Combine like term

$t=10$

Hence, The solution of the equation is t=10

3 ( 2t + 5 ) = 5 t + 25

3 * 2 t + 3 * 5 = 5 t + 25

6 t + 15 = 5 t + 25

6t - 5t = 25 - 15

t = 10

Hope this helps!

Jason has a piece of wire that is 62.4 inches long. He cuts the wire into 3 equal pieces. Which is the best estimate of the length of each piece of wire.

Answers

Answer:

The best estimate of the length of each piece of wire is 20.8 inches (Approx).

Step-by-step explanation:

Let us assume that the length of each pieces of wire be x.

As given

Jason has a piece of wire that is 62.4 inches long.

He cuts the wire into 3 equal pieces.

Than the equation becomes

3x = 62.4

$x = (62.4)/(3)$

x = 20.8 inches (Approx)

Therefore the best estimate of the length of each piece of wire is 20.8 inches (Approx).

62.4/3=20.8 is one of the 3 wires that are equal

At a local store you find the following prices listed: Cellophane tape - 2 rolls for $1.28
Note pads - 3 pads for .87
Highlighters - 1 for 1.59
Ink cartridges - 2 boxes for 1.98
How much would you pay for one roll of tape, two note pads, two highlighters, and two boxes of ink cartridges?

Answers

2 rolls of tape cost $1.28, so to find out how much one costs, u have to split it in half = 64 cents

3 note pads cost 0.87 cents, so first u have to find out how much one costs. You have to do 0.87÷3 = 0.29. Since you are buying 2 you have to multiply 0.29×2 = 58 cents

1 highlighter costs 1.59, you want to buy to so you have to multiply. 1.59×2 = 3.18 dollars

Ink cartridges are already calculated in 2 so the cost for the cartridges is gonna be = 1.98 dollars

Now since u have all the prices for quantity u need u just have to add.
.64 + .58 + 3.18 + 1.98 = $6.38

Your FINAL TOTAL ANSWER is $6.38
Hope I helped :)

Just find the unit price for each item then muktiply it by how many your buying. To find unit orice you divide price by amount. Then multiply that by 2 if your finding two, 3 and so on. Then add all the bumbers up
