Beverly is making peanut butter-banana bread. She always doubles the amount of nuts and peanut butter chips. The total amount of chips and nuts after doubling is 4 1/2 cups. The recipe says one and a half cups of peanut butter chips, an unknown number of cups of nuts, and three very ripe bananas. Write and solve an equation to find the original amount of nuts, x, in the recipe.
Answer:
0.75 or three-fourth of a cup of nuts.
Step-by-step explanation:
Given that:
Original recipe has
1. One and half cups of peanut butter
2. Unknown number of cups of nuts, let this amount be [tex]x[/tex] cups.
3. Three very ripe bananas.
Total amount of chips and nuts after doubling = [tex]4\frac{1}{2}[/tex] cups
Before doubling, total amount of chips and nuts = [tex]4\frac{1}{2} \div 2 = 2.25[/tex]
Now, as per given question statement:
[tex]2.25=x+1.5[/tex]
Subtracting the number 1.5 from both the sides to find the value of [tex]x[/tex]:
[tex]2.25-1.5=x\\\Rightarrow x = \bold{0.75}[/tex]
Therefore, 0.75 or three-fourth of a cup of nuts is the original amount in the recipe.

Answer:
A.
Step-by-step explanation:
When you divide 4, it isolates the variable giving you your answer in the equation.
Answer: The answer is A, dividing both sides by 4 eliminates the variable.
Step-by-step explanation: We can find this out by following along with the steps in the process. Since we need to remove the coefficient from “x” to simplify the equation, you must divide both sides by 4 to keep both sides of the equal sign balanced. How this helped! :)

Zachary is planning to send a video game to each of his two brothers. If he buys the same game for both brothers and pays $2.75 to ship each game, how much can he spend on each game without spending more than $100? Enter and solve an inequality for this situation. Let v be the cost of one video game
Given that,
He buys the same game for both brothers and pays $2.75 to ship each game, how much can he spend on each game without spending more than $100.
We need to solve the inequality for this situation.
Let he spent $x on each of the video game. ATQ,
[tex]2x+2\times 2.75\le 100\\\\2x+5.5\le 100\\\\2x\le 100-5.5\\\\2x\le 94.5\\\\x\le \$47.25[/tex]
So, he can spend less than or equal to $47.25 on each game.

To win a trivia game, Nevan must score 90 points.
Each correct answer is worth 1 and 3/4 points, and each incorrect answer is worth −14 points.
If he gets 58 questions correct and 22 questions incorrect, does Nevan win? How many points does he score?
Answer:
Step-by-step explanation:
For correct questions
1 correct questions = 1 3/4 points
1 correct question = 7/4 points
Since he got 58correct questions, tgw total points he earned will be;
58 × 7/4
= 406/4
= 101.5points
For incorrect questions
1 incorrect question = -14points
22 incorrect = -14×22
22incorreft = -308points
Total points gained/lost =-308+101.5
Total points lost = -206.5
Since Nevan has a negative point of -206.5, this means that he lost.
He scored -206.5points

The distance, y, in centimeters, of an ant from a hole in the tree for a certain amount of time, x, in seconds, is shown in the graph:
A graph titled Motion of Ant is shown. The graph shows time in seconds on the x-axis and the Distance from Hole in centimeters on the y-axis. The scale on the x-axis is shown from 0 to 6 at increments of 1, and the scale on the y-axis is shown from 0 to 12 at increments of 2. The graph has 3 straight lines. The first line is labeled P and joins ordered pairs 0, 0 and 2, 6. The second line is labeled Q and joins ordered pairs 2, 6 and 3, 6. The third line is labeled R and joins ordered pairs 3, 6 and 5, 0.
Part A: Is the graph linear or nonlinear? Explain your answer. (2 points)
Part B: In which segments is the graph increasing, decreasing, and constant? (3 points)
Part C: In your own words, describe the motion of the ant, as shown on the graph. (5 points)
Answer:
A: Nonlinear
B: Constant=0, Decreasing=M, Increasing=K
C: 2-3-3
Step-by-step explanation:
1. Linear graph - one with a line that has the same slope all the way through
The line doesn't have the same slope the whole way through because at one part it flattens and also decreases
---------------------------------------------------------------------------------
2. Remember: Increase (up), decrease (down), constant (constant)
---------------------------------------------------------------------------------
3. In my words, I don't know if they're asking the pattern or technical, but you can add on to the 2 mins walk, 3 mins stop, then 2 mins walk again.

Name all of the angle(s) that are adjacent and congruent to angle BDC
Answer:
im not sure if im entirely correct, so i apologize in advance
<HDF
<BDG (i think)
<CDE
Step-by-step explanation:
The angles that are adjacent and congruent to ∠ BDC are ∠ HDF , ∠EDH and ∠CDE.
A figure is given in the question.
We have to tell about angles which are congruent to ∠ BDC.
What are the adjacent angles ?
The two angles are said to be adjacent angles when they share the common vertex and side.
As per the definition of adjacent angles ;
we can check for the adjacent angles from the figure.
Here ;
∠ BDC = ∠ HDF.
∠ BDC = ∠ EDH.
∠ BDC = ∠ CDE.
To check , if these are congruent too ; we must know that two angles are congruent when they have the same angle measurement, i.e., they’re equal.
if we compare from the figure ; we found that these angles are also congruent to each other.
Thus , the angles that are adjacent and congruent to ∠ BDC are ∠HDF , ∠EDH and ∠CDE.

Graph line with the equation y=x+6. (Can you explain how to do this overall)
Answer:
First using y = Mx + b with m = slope and b = y intercept so 1/3 = slope and (0,6) is y intercept next plot (0,6) the plot slope from that point with rise/run or from point (0,6) go up +1 point and over +3 and make a point then go up +1 and over +3 or from (0,6) use slope = -1/-3 since they equal the same thing. So from point (0,6) go down -1 and to the left -3. Then draw your line.
