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.

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

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

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
