Answer:
Step-by-step explanation:
Sweet. Get to answer finally. I was the guy commenting on your other post.
1. 72
2. 46
3. 99
4. Same side interior angles are supplementary
5. alternate interior angles are equal to each other so set up the x expressions equal to each other. 5x-7=3x+17. Solve for x
5x-7=3x+17
2x=24
x=12
plug it in for the 5x-7 and get an angle.. 5(12)-7
60-7
53.
The 5x-7 and the 4y+3 is supplementary.
so 53+3+4y=180. combine the 2 and set them equal to 180 to find y
56+4y=180
124=4y
y=31
And now we find the angle of 6. We know that corresponding angles are equal and the y expression and angle 6 are corresponding angles
so plug in your answer for y in the expression..
4(31)+3 = 127.
so angle 6 is 127
$1.45
1.50 times .05= 0.075
the sales tax was 0.075 cents, so if you subtract that from $1.50, you get the price before sales tax
Answer:
-20
Step-by-step explanation:
6-6-20=-20
How can you determine the best method of solving a system of equations?
Elimination is best used when both equations are in standard form (Ax + By = C).
Elimination is also the best method to use if all of the variables have a coefficient other than 1.
