Explain to Raven what she did correctly in the first two problems that she did not do in the last problem, and how to correct her mistake
Answers
Answer:
She changed the symbols in the first two problems because they were divided by a negative number whereas she shouldn't have changed the symbol in the last problem as it was not divided by a negative number and so the sign remains the same.

What is the missing term?
Answers
Answer:
Missing term = 6x
Step-by-step explanation:
We got:
=> 4x by multiplying +4 and x (x * 4 = 4x)
=> 12 by multiplying +4 and +3 (4 * 3 = 12)
=> 2x² by multiplying 2x and x (2x * x = 2x²)
Similarly we will get the "missing term" by multiplying 2x and +3
=> Missing term = 6x, (2x * 3 = 6x)
Hope this helps!

Step-by-step explanation:
I graphed it too using desmos then located the point where they cross, the solution point, and it was at the x value of 6 and they will have made $50 by the way in case you wanted to know that too so we see that on the graph at the point (6,50) is where they make the same amount of money.

Professor Turner wrote the expression below on the chalkboard for his team at the Research Center. He asked the scientists there to write an equivalent expression that eliminated the parentheses.
Answers
Answer:
12x + 18y + 6z + 4x - 4z
Step-by-step explanation:
Given the expression : 3(4x + 6y + 2z) + 4(x – z)
To eliminate the parenthesis ; we use the distributive property :
3(4x + 6y + 2z) + 4(x – z) becomes ;
3*4x + 3*6y + 3*2z + 4*x + 4*-z
12x + 18y + 6z + 4x - 4z
Hence,
12x + 4x + 18y + 6z - 4z
16x + 18y + 2z

Answers
Answer:
2 yards 5 inches will be equivalent to 77 inches
Step-by-step explanation:
Given length -
2 yards 5 inches
One yard has 36 inches
Two yards will have 2*36 = 72 inches
Thus, 2 yards 5 inches will sum up to 72 inches + 5 inches = 77 inches
Hence, 2 yards 5 inches will be equivalent to 77 inches
Answer:
3 yards = 9 feet
77 inches = 2 yards 5 inches
48 inches = 1 yard 1 foot
32 inches = 2 feet 8 inches

The value of m is the expression x⁴ + mx² + 64 a perfect square will be 16.
What is a perfect square trinomial?A perfect square trinomial formulation can be created by taking the binomial equation's squared. If and then only if a trinomial satisfying the criterion b² = 4ac has the form ax² + bx + c, it is indeed a perfect square.
The equation is given below.
⇒ x⁴ + mx² + 64
Then the value of a, b, and c will be 1, m, and 64, respectively. Then the equation will be given as,
b² = 4ac
m² = 4 x 1 x 64
m² = 265
m² = 16²
m = 16
The value of m is the expression x⁴ + mx² + 64 a perfect square will be 16.

Answer:
(5x + 16) + 102 + 92 + 100 = 360
(5x + 16) + 294 = 360
-294 -294
5x + 16 = 66
-16 -16
5x = 50
Divide by 5 on both sides.
x = 10 degrees

1 In triangle MNP the measure of angle NPM is 80° and the measure of angle MNP is 22.5°.
What is the measure of angle PMN in degrees?
Answers
Answer:
77.5°
Step-by-step explanation:
Recall that the sum of angles in a triangle is 180 degrees.
Given the triangle MNP with the measure of angle NPM is 80° and the measure of angle MNP is 22.5°
Then
angles NPM + MNP + PMN = 180 degrees
This means that
80 + 22.5 + PMN = 180
102.5 + PMN = 180
Collect like terms
PMN = 180 - 102.5
= 77.5°.
Here's the number line what fraction of 1 foot is 3 inches what fraction of one yard is 3 inches explain
Answers
Answer:
1/4 and 1/12
Step-by-step explanation:
We know that
1 foot = 12 inches
therefore, 1 inch = 1/12 foot
hence, 3 inches = 3/12 foot
= 1/4.
Therefore, the required fraction is = 1/4
Similarly,
1 yard = 36 inches
This implies 1 inch = 1/36 yard
Hence, 3 inches = 3/36 = 1/12
Therefore, the required fraction = 1/12
