I need help ASAP!!!!!!!! PLEASE CORRECT ANSWER!
A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
A triangle ABC is shown. The base of the triangle extends into a straight line. The angle formed between this straight line and the edge of the triangle is marked as w. The angle adjacent to w is marked as z, and the other two angles inside the triangle are marked as x and y.
Step 1: m∠x + m∠y + m∠z = 180 degrees (sum of angles of a triangle)
Step 2: m∠w − m∠z = 90 degrees (corresponding angles)
Step 3: Therefore, m∠x + m∠y + m∠z = m∠w + m∠z
Step 4: So, m∠x + m∠y = m∠w
In which step did the student first make a mistake and how can it be corrected? (5 points)
Select one:
a. Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (sum of corresponding angles)
b. Step 2; it should be m∠w + m∠z = 180 degrees (supplementary angles)
c. Step 1; it should be m∠x + m∠y + m∠z = 90 degrees (corresponding angles)
d. Step 2; it should be m∠w + m∠z = 90 degrees (alternate exterior angle)

[tex]2x - 6 + 3 = 6x - 5[/tex]
[tex]2x - 3 = 6x - 5[/tex]
[tex]6x - 5 = 2x - 3[/tex]
Add sides 5
[tex]6x - 5 + 5 = 2x - 3 + 5[/tex]
[tex]6x = 2x + 2[/tex]
Subtract sides 2x
[tex] - 2x + 6x = - 2x + 2x + 2[/tex]
[tex]4x = 2[/tex]
Divide sides by 4
[tex] \frac{4x}{4} = \frac{2}{4} \\ [/tex]
[tex]x = \frac{1}{2} \\ [/tex]
_________________________________
CHECK :
[tex]2( \frac{1}{2} ) - 3 = 6( \frac{1}{2} ) - 5 \\ [/tex]
[tex]1 - 3 = 3 - 5[/tex]
[tex] - 2 = - 2[/tex]
Thus the solution is correct....

First combine like terms:
you can add 6 and 3 in 2x-6+3
2x-9=6x-5
Second get x alone:
you can add 9 to both sides and get
2x=6x+4
then you can subtract 6 from both sides which would leave you
-4x=4
finally divide -4 from both sides and you get
x=-1
I hope this helps! Have a nice day or night :)

A block of clay contains twenty 4 - ounce portions of clay. Ceramics teacher wants to use the block to make as many spheres of clay as possible. Each weighing ⅖ pound. How Many spheres can the class make
Answers
Answer:
12.5
Step-by-step explanation:
20 x 4 = 80

5 ÷ 2/5 = 12.5
Using 24 ounce portions of clay, maximum they can make 3 spheres.
Given that, a block of clay contains 24 ounce portions of clay.
What is metric conversion?Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
We know that, 1 pound = 16 ounces
So, 1 ounce = 1/16 pound
Then 24 ounce = 24/16
= 1.5 pound
Here, each sphere of clay weighing 2/5 = 0.4 pounds
Number of spheres = 1.5/0.4
= 3.75
Maximum 3 spheres
Therefore, using 24 ounce portions of clay, maximum they can make 3 spheres.

Answers
Answer:
1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)
2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal
3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.
