3x+1/5y=7 solve for y

Answers

Answer 1
Hello!

First, let's write the problem.
[tex]3x+\frac{1}{5}y=7[/tex]
Subtract 3x from both sides.
[tex]3x+\frac{1}{5}y-3x=7-3x[/tex]
[tex]\frac{1}{5}y=7-3x[/tex]
The opposite of division is multiplication, so we are going to multiply in order to undo the fraction.
[tex]5\cdot \frac{1}{5}y=5\cdot \:7-5\cdot \:3x[/tex]

Our final answer would be, 
[tex]y=35-15x[/tex]

Thanks!

factor the algebraic expression 16a + 10

Answers

really???????? Chay its me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The factored form of the expression 16a + 10 is 2(8a + 5).

To factor the expression 16a + 10, we can divide each term by the greatest common factor (GCF) of the expression.

The GCF of 16a and 10 is 2, so we can divide each term by 2 to get:

16a + 10 = 2(8a + 5)

Therefore, the factored form of the expression 16a + 10 is 2(8a + 5).

Use properties of addition to find 37+58 mentally.show your steps and identify the properties the you used

Associative property of addition commutative property or identity property show me steps plz

Answers

if your trying to find the sum of 37=58 the steps would be:

Units - 7+8=15
Tens - 30+50=70
= 70+15 = 85

Answer:

To sum 37+58 mentally, we could first sum 30+50=80 and then sum the units, 80+7+8= 95.

But, if we have to show properties, we could separate first the numbers:

30 + 7 + 50 + 8.

Then, we apply commutative property to position like numbers aside:

30+50+7+8

Then, we apply associate property, to have a better order of the operation, which is easier to the mind:

(30+50) + (7+8)

Then, we sum each group:

80 + 15

At last, we sum again and have the result:

80+15=95.

Mark is using the ratio of 3 tablespoons of sugar to 2 tablespoons of milk in a recipe .what its the equivalent ratio if mark decides to increase the recipe

Answers

Final answer:

To maintain an equivalent ratio of sugar to milk when increasing a recipe, multiply both the sugar and milk amounts by the same factor. For example, multiplying by 5 results in a ratio of 15 tablespoons of sugar to 10 tablespoons of milk.

Explanation:

If Mark is using a ratio of 3 tablespoons of sugar to 2 tablespoons of milk in a recipe and decides to increase the recipe, we need to maintain the same ratio for any quantity. An equivalent ratio can be found by multiplying both parts of the original ratio by the same number. For example, if Mark wanted to double the recipe, he would use 6 tablespoons of sugar and 4 tablespoons of milk (3 x 2 = 6 and 2 x 2 = 4), keeping the same ratio of 3:2.

To increase the recipe to any desired amount, Mark could use a conversion factor. For instance, if the original recipe makes 1 batch and Mark wants to make 5 batches, he multiplies both parts of the ratio by 5. The new ratio would be 15 tablespoons of sugar to 10 tablespoons of milk, as 3 x 5 = 15 and 2 x 5 = 10. This maintains the sweetness and consistency of the recipe across a larger volume.

Consider statement: If a quadrilateral is a rectangle then it is a parallelogram. Wright the inverse and contrapositive of the original statement. Are they true? Explain.

Answers

Inverse- If a quadrilateral is not a rectangle, then it is not a parallelogram. 

Contrapositive- If a quadrilateral is not a parallelogram, then it is not a rectangle. 

The inverse is false- there are non-rectangular parallelograms. The contrapositive is true- a rectangle will always be a parallelogram, so if a shape isn't a parallelogram, it cannot be a rectangle.

The soccer team voted on what they wanted to eat. There are 20 members on the team. Six members voted for pizza, 10 voted for chicken, and the rest voted for hot dogs.

Which ratio represents the number of votes for hot dogs to chicken?

1/5

2/5

3/5

5/2

Answers

the answer is 2/5 because hot dog to chicken is 4/10 and if u simplify u get 2/5

Answer : The ratio represents the number of votes for hot dogs to chicken is, [tex]\frac{2}{5}[/tex]

Step-by-step explanation : Given,

Number of members voted for pizza = 6

Number of members voted for chicken = 10

Number of members voted for hot dogs = 20 - (10 +6) = 4

Now we have to determine the ratio represents the number of votes for hot dogs to chicken.

[tex]\frac{\text{Number of members voted for hot dogs}}{\text{Number of members voted for chicken}}=\frac{4}{10}[/tex]

[tex]\frac{\text{Number of members voted for hot dogs}}{\text{Number of members voted for chicken}}=\frac{2}{5}[/tex]

Thus, the ratio represents the number of votes for hot dogs to chicken is, [tex]\frac{2}{5}[/tex]

Write a real-world problem that can be represented by the inequality r + 32 (greater then or equal to sign) 56

Answers

Dominic wants to say up for a game that is $56. He needs at least $56 dollars to buy the game. He has $32 currently. How much more money does he need to be able to afford the game?
Final answer:

The real-world problem involves maintaining a minimum safe temperature in an animal shelter that can be represented by the inequality r + 32 ≥ 56, which simplifies to r ≥ 24 after subtracting 32 from both sides.

Explanation:

Consider a situation where r represents the room temperature in degrees Fahrenheit without accounting for wind chill or humidity, and the inequality r + 32 ≥ 56 represents the minimum safe temperature that must be maintained in an animal shelter to keep the animals comfortable during winter months.

To solve the inequality for r, we would subtract 32 from both sides:

   

So, the shelter must keep the room temperature at 24 degrees Fahrenheit or higher to ensure the animals' safety.

If we were to compare this with mathematical rules presented in LibreTexts, subtracting the same number from both sides of an inequality does not change the relationship, which is a standard procedure for solving inequalities.

Answers

The model will be 3.055 feet

Answer: 3.055 feet

Step-by-step explanation:

Given : The statue of liberty is 305.5 feet tall from the foundation of its pedestal to the top of its torch.

Its model will be one hundredth times as tall as the actual statue.

Now , One hundredth = [tex]\dfrac{1}{100}=0.01[/tex]

According to the statement,

The height of the model will be = [tex]\dfrac{1}{100}\times\text{Height of original statue}[/tex]

[tex]=\dfrac{1}{100}\times305.5=3.055\text{ feet}[/tex]

Hence, the height of the model will be 3.055 feet.

A number is 42,300 when multiplied by 10. Find the product of this number and 500.

Answers

I believe the answer is 4,730! Hope this helps!

The product of the missing number (4,230) is 2,115,000

If a number is multiplied by 10, it will yield 42,300. To determine the missing number, 42,300 will be divided by 10.Further Explanation

Therefore let the missing number be X

Hence,

X = 42300 ÷ 10

X = 42300 / 10

X = 4,230

Therefore the missing number is 4230.

Recall, we are to find the product 4230 and 500. This process require that we multiply 4230 and 500.

Therefore, let the product of 4,230 and 500 be P

P = 4230 x 500

P = 2,115,000

Hence, the product of the missing number (4230) and 500 is 2,115,000.

Michelle made a bead necklace that was 14 inches long. The length of the necklace, in inches, is equal to 4 added to one-seventh the number of beads, b.

1/7b + 4 = 14

How many beads did Michelle use for her necklace?
70
17
35
700

Answers

Final answer:

Michelle used 70 beads to make her 14-inch long necklace, as determined by solving the equation 1/7b + 4 = 14 and isolating the variable b.

Explanation:

The question asks us to solve for the number of beads, b, in a necklace that is 14 inches long. The equation given is 1/7b + 4 = 14. We need to solve for b.

To solve for b, we first subtract 4 from both sides of the equation to get 1/7b = 10. Next, we multiply both sides by 7 to isolate b on one side of the equation, which gives us b = 70. Therefore, Michelle used 70 beads for her necklace.

If carrots were $0.50 less per pound how much would Victoria have paid for 8.5 pounds of carrots

Answers

Final answer:

Victoria would have paid $4.25 for 8.5 pounds of carrots if they were $0.50 less per pound.

Explanation:

To find out how much Victoria would have paid for 8.5 pounds of carrots if they were $0.50 less per pound, we need to subtract $0.50 from the original price per pound and then multiply it by 8.5.



Let's say the original price per pound of carrots is $1.00. Subtracting $0.50 from it gives us $0.50. Multiplying $0.50 by 8.5 gives us $4.25.



Therefore, Victoria would have paid $4.25 for 8.5 pounds of carrots if they were $0.50 less per pound.
