Simplify the expression 3t+5t-2t=6t
Answer:
t=1
Step-by-step explanation:
First combine the like terms
3t+5t+2t=6t 3+5-2=6
6t=6t
then divide each side by 6 to simplify
6t=6t
-------
6 6
t=6/6
t=1
Find the slope of 6x – 3y = 5
Answer:
slope is 2
Step-by-step explanation:
simplify this equation so that you can get to "y ="
your equation is: 6x - 3y = 5
start by subtracting 6x from both sides: -3y = -6x - 5
then divide both sides by -3 to isolate y: y = 2x - 5/3
so now we can clearly see that the slope is 2, since that is what is right next to x

Step-by-step explanation:
Hope i could help
Answer:
[tex]827.39yd^{3}[/tex]
Step-by-step explanation:
The formula to find the volume of a rectangular prism is length times width times height ([tex]lwh[/tex]). So, multiply the three numbers and you’ll get [tex]827.39yd^{3}[/tex]. You always have to cube the units. So you have to cube the yd.

Answer: Answer is D
Step-by-step explanation:
A simple way to explain nonlinear is when the line is curvy.
Lindsey's goal is to sell at least 35 candles at each of 15 craft fairs. She makes 24 candles each day for 20 days. Use the drop-down menus to explain whether Lindsey makes enough candles to reach her goal.
Answer:
D.Lindsay makes 480 candles. She divides 480 by 15 to get 32. She does not make enough candles.
Step-by-step explanation:
The explanation of the sufficient candles that are required to check whether she reach her goal or not is as follows:
She makes 480 candles that come from
= 24 candles each days × 20 days
= 480 candles
Now if we divide the 480 candles from 15 so we get 32
This is less than the minimum candles required i.e. 35
So, the option D is correct

Answer:
The measure of angle two is 47 degrees (first triangle), and the measure of angle four is 42 degrees (second angle)
Step-by-step explanation:
Remember that all triangles have a full measurement of 180 degees.
Since measure one is is 65 degrees, we need to add 65 and 68, which is 133 degrees.
Now we subtract 180 - 133 = 47.
The measure of angle two is 47 degrees.
Since the angle of measure three is 89 degrees, we need to add 89 + 49, which is 138 degrees.
180 - 138 = 42.

Make x the subject of the formula y=9ax-4b
helppp
Answer:
take out the a with an equation
The solution of x is y+4b/9a for equation y=9ax-4b
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is y=9ax-4b
y equal to nine times of and x minus four times of b.
We need to solve for x
Add 4b on both sides
y+4b=9ax-4b+4b
y+4b=9ax
Divide both sides by 9a to separate x on RHS
y+4b/9a=x
Hence the solution of x is y+4b/9a for equation y=9ax-4b
