One week gas $1.25 gallon the next sweet gas was $1.50 per gallon by what percentage to the price increase

Answers

Answer:

20%

Step-by-step explanation:

The first step is to calculate the increase

= 1.50-1.25

= 0.25

Therefore the percentage increase can be calculated as follows

= 0.25/1.25 × 100

= 0.2 × 100

= 20%

Hence the price increased by 20%

You can solve the equation 2x + 7 = 1 - x by graphing y = 2x + 7 and y = 1 - x and finding the point of intersection

Answers

Answer:

x = -2

Step-by-step explanation:

You can also solve for the equation given.

2x + 7 = 1 - x

3x = -6

x = -2

The solution to the equation 2x + 7 = 1 - x is x = -2.

To solve the equation 2x + 7 = 1 - x by graphing, we can plot the two equations on a graph and identify the point where they intersect.

First, let's graph y = 2x + 7 and y = 1 - x on the same coordinate system.

The equation y = 2x + 7 represents a straight line with a slope of 2 and a y-intercept of 7.

The equation y = 1 - x represents a straight line with a slope of -1 and a y-intercept of 1.

Plotting these lines, we can see that they intersect at a specific point on the graph. The coordinates of this point represent the solution to the equation 2x + 7 = 1 - x.

By visually inspecting the graph, we can determine the point of intersection, which is approximately (-2, 3). This means that x = -2 is the solution to the given equation.

David's bowling score is 6 less than 2 times Aaron's score. The sum of their scores is 84. Find the score of each student. Use the variable a for Aaron's score.

Answers

Answer:

Aaron's bowling score is 30

David's bowling score is 54

Step-by-step explanation:

The variable representing Aaron's score is = a

The variable representing David's bowling score = d

The sum of their scores is 84.

= a + d = 84...... Equation 1

David's bowling score is 6 less than 2 times Aaron's score.

d = 2a - 6

Substituting 2a - 6 for d in Equation 1

a + 2a - 6 = 84

3a - 6 = 84

3a = 84 + 6

3a = 90

a = 90/3

a = 30

Hence, Aaron's bowling score is 30

d = 2a - 6

d = 2(30) - 6

d = 60 - 6

d = 54

David's bowling score is 54

A jeweler wants to make 14 grams of an alloy that is precisely 75% gold.. The jeweler has alloys that are 25% gold, 50% gold, & 82% gold. Choose 2 different alloys that can be used to create one that is 75% gold. pls try to explain with a system of equations ; ;

Answers

Given that the jeweler has alloys that are 25% gold, 50% gold, and 82% gold.

As he wants to make 14 grams of an alloy by adding two different alloys that is precisely 75% gold, so one alloy must have a percentage of gold more than 75%.

One alloy is 82% gold and, the second can be chosen between 25% gold, 50% gold, so there are two cases.

Case 1: 82% gold + 50% gold

Let x grams of 82% gold and y  grams of 50% gold added to make x+y=14 grams of 75% gold, so

75% of 14 = 82% of x + 50% of y

[tex]\Rightarrow 75/100 \times 14 = 82/100 \times x + 50/100 \times y \\\\[/tex]

[tex]\Rightarrow 75/100 \times 14 = 82/100 \times x + 50/100 \times (14-x)[/tex]  [as x+y=14]

[tex]\Rightarrow 75 \times 14 = 82 \times x + 50 \times (14-x) \\\\\Rightarrow 75 \times 14 = 82 \times x + 50 \times14-50\times x \\\\\Rightarrow 75 \times 14 = 32 \times x + 50 \times14 \\\\\Rightarrow 32 \times x =75 \times 14 - 50 \times14 \\\\[/tex]

[tex]\Rightarrow x =(25 \times 14)/32=10.9375[/tex] grams

and [tex]y = 14-x= 14-10.9375=3.0625[/tex] grams.

Hence, 10.9375 grams of 82% gold and 3.0625  grams of 50% gold added to make 14 grams of 75% gold.

Case 2: 82% gold + 25% gold

Let x grams of 82% gold and y  grams of 25% gold added to make x+y=14 grams of 75% gold, so

75% of 14 = 82% of x + 25% of y

[tex]\Rightarrow 75/100 \times 14 = 82/100 \times x + 25/100 \times y \\\\\Rightarrow 75/100 \times 14 = 82/100 \times x + 25/100 \times (14-x) \\\\ \Rightarrow 75 \times 14 = 82 \times x + 25 \times (14-x) \\\\\Rightarrow 75 \times 14 = 82 \times x + 25 \times14-25\times x \\\\\Rightarrow 75 \times 14 = 57 \times x + 25 \times14 \\\\\Rightarrow 57 \times x =75 \times 14 - 25 \times14 \\\\[/tex]

[tex]\Rightarrow x =(50 \times 14)/57=12.28[/tex] grams

and [tex]y = 14-x= 14-12.28=1.72[/tex] grams.

Hence, 12.28 grams of 82% gold and 1.72  grams of 50% gold added to make 14 grams of 75% gold.

what's the midpoint of (-10,3) and (0,9)

Answers

Answer:

To find the midpoint we need to find the point which is the same distance between the x and y values in both points. For example the distance to a point that will be shared among the 2 x's is -5. -10 (x1) and 0 (second x value) are both 5 units away from -5. to -5 is the x of our new point: (-5, y)

Now do the same for the y value:

9-3=6

6 is the y value of our new point

5. Amy has 10 yd of fence to put around a tree. She uses all the fence to make six

sections that are the same length. Which expression does NOT equal the length of one

of these sections in yards?

Answers

Answer: See explanation

Step-by-step explanation:

You didn't give the options but let me help out.

From the question, we are informed that Amy has 10 yd of fence to put around a tree and that she uses all the fence to make six sections that are the same length.

The expression that will be equal to the length of one of these sections in yards will be:

= 10 yards / 6

= 1.67 yards or 1 2/3 yards

This means that any option that you see that is different from the answer above will be the answer based on your question.
