-2x+5y=7
2x-5y=-7 What is the solution?

Answers

Answer 1
-2x+5y=7
add 2x to both sides:
5y=2x+7
Divide everything by 5 to get y by itself:
y = 2/5x+7/5

————————————
2x-5y=-7
Subtract 2x from both sides
-5y=-2x-7
Divid by -5 to get y by itself
y=2/5x+7/5

In the morning, a farmworker packed 4 pints of strawberries every 4 minutes. In the afternoon, she packed 3 pints of strawberries every 5 minutes. What was the difference between her morning and afternoon packing rates, in pints per hour?

Answers

Answer: 24

Step-by-step explanation:

In the morning, a farmworker packed 4 pints of strawberries every 4 minutes. The amount of pints of strawberries packed in an hour would be:

= 4/4 × 60

= 60 pints of strawberries

In the afternoon, she packed 3 pints of strawberries every 5 minutes. The amount of pints of strawberries packed in an hour would be:

= 3/5 × 60

= 36 pints of strawberries

The difference between her morning and afternoon packing rates, in pints per hour would be:

= 60 - 36

= 24

question 1 is 22

question 2 is 122

ask your teacher why u got question 1 wrong

Step-by-step explanation:

90-68 is 22

180-58= 122

Answer:

1. 22 degrees

2. 122 degrees

3. Angle 1 is supplementary to angle 6

Step-by-step explanation:

1. It is supposed to be a right angle which means that 90. So, to find GHK you must do 90 - 68 = 22. I don't understand why it is incorrect but, I can promise you that is the correct answer

2. A straight angle is 180 degrees. So, you would subtract 180 - 58 = 122.

Therefore, your answer for 2 would not be 112 degrees it would in fact be 122 degrees.

3. Evidence in the picture below:

Kristina made rectangular place mats for her dining room table, as shown below. The area of each place mat is 135 square Inches. The width of each place mat is 9 inches. How many inches long are all the sides of the place mat? Figure not drawn to scale. in 9 in in in​

Answers

Answer:

The length of all sides of place mat is 48 inches.

Step-by-step explanation:

Given that:

Area of place mat = 135 square inches

Width of place mat = 9 inches

Length of place mat = x

Area = Length * Width

135 = 9x

[tex]\frac{9x}{9}=\frac{135}{9}\\x = 15[/tex]

For length of all sides, we will find the perimeter.

Perimeter = 2(Length + Width)

Perimeter = 2(15+9)

Perimeter = 2(24) = 48 inches

Hence,

The length of all sides of place mat is 48 inches.

Answer:

We can write proportion as:

Step-by-step explanation:

A cyclist rides at a constant speed, traveling 30 miles in 1.5 hours. Write a proportion that gives the number x of miles the cyclist rides in 4 hours

Proportion:

A proportion is used when two ratios are equal. It can be written as a/b=c/d

In our case we have:

a= 30 miles

b = 1.5 hours

c = x miles

d = 4 hours

We can write proportion as:
