# 3n t 4 = 7 solve it

QUESTION POSTED AT 26/03/2020 - 08:18 AM

You would subtract 4 from both sides. Then it would be 3n = 3. You would then divide each side by 3. The answer you would get is n = 1.

#4)
{ A}
Triangle ABC is congruent to triangle YXZ. How do I know this?
Look at the angles and adjacent (bottom) line.
Because Angle A and Angle Y are both equal to (what I believe says) 78 degrees, they are equal.
Next, Angle B is equal to Angle X because it is the angle that connects the adjacent (bottom) line and the hypotenuse (top line). Even though they have no measurements or tick marks, it's the process of elimination.
Finally, Angle C and Angle Z. We know that these are equal do to their degree similarity of (what I think is) 65.

{B} Triangle ABC is congruent to Triangle RSQ. How do I know this?
Because Angle A is congruent to the only other angle there, Angle R.
Next, B and S are congruent. If you think of them as angles, then you can see that "angle" b is connected to the leg of AB and BC. AC has one tick mark, as does RS. BC has no tick or anything to note it's congruence. So because Point be is stick in between a leg with one tick and one leg with no tick, look for the similarity in triangle RSQ. The similarity showing as S. You should understand enough now to know how I got how C and P are congruent.

#5) Sadly I cannot read the diagram they provide, so I cannot help with it.

#6) The length of BC: ?  The length of XZ:   ?  Measure of Angle BZX: 55 degrees.

### How do you solve 2ln(2x+5)=8 ?

Well you have to use one of the logarithm laws
b * ln (x) = ln (x^b)
So
2 ln (2x + 5) = 8
ln [(2x+5)^2] = 8

So now if we do e^x on both sides and we say that x is going to be what either side equals like this
e^(ln [(2x+5)^2]) = e^8

We we know that
e^[ln (x)] = x so

[(2x+5)^2] = e^8

take square root of both sides
2x + 5 = e^4. and -(2x+5) = e^4
2x = e^4 - 5. and -2x = e^4 + 5
x = (e^4 - 5)/2 and x =(e^4 + 5) / -2

now just use a calculator to solve

### I know the answer is C. but I need to know how to solve it!

Yes you are right it's C)
Notice  that f(-2) = (-2)³ +2( - 2)² + 4(-2) + 8 =0
Then x³+2x²+4x+8 is divisible by (x+2)
Perform this division & you will get:

x³+2x²+4x+8 = (x+2)(x²+4)
The root of (x+2) is the value that render it nil, that is x=-2
The root of (x²+4) are imaginary (not real) because
x²+4 =0 ==> x² = -4 & x=√-4 or x= 2i (nor real).
Hope you understood the reasoning

### Which shows a correct order to solve this story problem? Kristie bought 4 drinks for \$1.99 each and 4 muffins for \$1.20 each at the local café. She left a \$2.30 tip for the server. How much did Kristie have left from the \$30 she took to the café? A. Step 1: Add the price of a muffin to the price of a drink. Step 2: Multiply that total by 4. Step 3: Subtract the total amount from \$30. Step 4: Add the tip. B. Step 1: Add the price of a drink and the tip. Step 2: Add the price of a muffin to the total from Step 1. Step 3: Multiply that total by 4. Step 4: Subtract that total amount from \$30. C. Step 1: Calculate the price of 4 drinks. Step 2: Calculate the price of 4 muffins. Step 3: Add the total amounts from Steps 1 and 2 to \$2.30. Step 4: Subtract that total amount from \$30.

Multiply \$1.99 by 4 for the drinks . Then \$1.20 by 4 for the muffins . Add both of the amounts from the drinks and muffins with the tip of \$2.30 . Then subtract \$30 from the other total . Then you have your answer .

### At a rugby tournament, each player on the top two teams receive medals. If 66 medals are purchased for the tournament, and each team has the same number of players, write an equation and then solve for the total number of medals needed for each team.

I'm not sure if this is what you're looking for, it's a pretty simple equation. What math are you in? This is how I would do it.
66=2x
Divide each side by 2
66/2=2x/2
33=x
(So each team would need 33 medals so that every player would get one)
