2a + 3b = 5
b=a-5 I need helppp

Answers

Answer 1

Answer:

4

Step-by-step explanation:

2a+3b=5

2a+3(a-5)=5

2a+3a-15=5

5a=5+15

5a=20

a=4

Answer 2

b = a - 5

_________________________

2a + 3b = 5

2a + 3( a - 5 ) = 5

2a + 3a - 15 = 5

5a - 15 = 5

5a - 15 + 15 = 5 + 15

5a = 20

5a ÷ 5 = 20 ÷ 5

a = 4

The ratio of dogs to cats is 4:3 in Jake's neighborhood. If there are 60 cats, how many dogs AND cats are there in the neighborhood?

Answers

Answer:

140

Step-by-step explanation:

dog : cat= 4 : 3

if there are 60 cats,

so, number of dogs = 4/3 × 60 = 80.

number of dogs AND cats = 80+60

= 140

Answer:

140 dogs and cats

Step-by-step explanation:

The ratio of dogs to cats is  4:3  or, as a fraction, 4/3.

Set up a proportion with 60 in the denominator (where the cats are!).

[tex]\frac{\text{dogs}}{\text{cats}}=\frac{d}{60}=\frac{4}{3}[/tex]

"Cross-multiply" (you may know this as the Means-Extremes property of proportions).

[tex]3d=(60)(4)\\3d=240\\d=80[/tex]

There are 80 dogs.

Finally, 80 dogs + 60 cats = 140 dogs AND cats

A shoe retailer decides to record the styles and sizes of shoes that his customers choose. He records this data for an entire year by keeping track of his customers' purchases. Which statement accurately describes the type of data the shoe retailer is collecting?

a. The shoe retailer is receiving available data on shoe sizes and styles from nearby shoe companies.
b. The shoe retailer is gathering available data because customers tell him which shoe sizes and styles they prefer.
c. The shoe retailer is gathering raw data because he is recording shoe sizes and styles by himself.
d. The shoe retailer is receiving raw data on shoe sizes and styles from nearby shoe companies.

Answers

Answer:

c. The shoe retailer is gathering raw data because he is recording shoe sizes and styles by himself.

Step-by-step explanation:

He records this data for an entire year by keeping track of his customers' purchases.

His customer's purchases will be from his shop and no one elses from the neighbours or of other company.

The only way to keep record of his customers' purchases is from his shop.

Option a is incorrect because he wants to check the drive force of his shop not other shops.

Option b is also incorrect because the items bought indicate the purchases not the preference told.

Option d is also incorrect becuase nearby companies wil have their own styles and sizes collection.

Sara drove 96 miles on 3.2 gallons of gas. How many miles can Sara drive on 12.5 gallons of gas

Answers

Answer:

375 miles

Step-by-step explanation:

Create a proportion where x is the number of miles she can drive on 12.5 gallons of gas:

[tex]\frac{96}{3.2}[/tex] = [tex]\frac{x}{12.5}[/tex]

Cross multiply and solve for x:

3.2x = 1200

x = 375

So, with 12.5 gallons of gas, Sara can drive 375 miles

375 miles 96 on 3.2 gallons of gas dived

Write the ratio of corresponding sides for the similar triangles and reduce the ratio to lowest terms.

Step-by-step explanation:

What is Exponential function?

A mathematical function with the formula f(x) = [tex]a^x[/tex] is an exponential function. where a is a constant known as the function's base and x is a variable. The transcendental number e, or roughly 2.71828, is the exponential-function base that is most frequently encountered.

As, there are 6 months from November to May.

Let the number of months be x.

So, the total is= 26[tex]( 1 + 36)^x[/tex]

when x= 6

So, total= 26[tex]( 1 + 36)^6[/tex]

Total = 6.328 x 26

Total = 164.5

Total = 165 people

There were 3 chihuahuas at the dog park last Saturday, along with 9 other dogs. Considering this data, how many of the next 20 dogs to arrive at the park next Saturday should you expect to be chihuahuas?

Answers

Answer:

5

Step-by-step explanation:

Since there are 3 chihuahuas out of 12 dogs IN TOTAL (which includes the 9 other dogs), the ratio is 1:4, or 1/4.

Assuming this ratio is consistent, (1/4)*20 is 5.

In conclusion, you can expect there to be 5 chihuahuas out of the next 20 dogs to arrive at the park.

192=6000(.02(8/5-4Y)+.08y)
solve for y

Answers

Given:

The equation is:

[tex]192=6000\left(0.02\left(\dfrac{8}{5}-4y\right)+0.08y\right)[/tex]

To find:

The value of y.

Solution:

We have,

[tex]192=6000\left(0.02\left(\dfrac{8}{5}-4y\right)+0.08y\right)[/tex]

On simplification, we get

[tex]192=6000\left(0.02\times 1.6-0.02\times 4y+0.08y\right)[/tex]

[tex]192=6000\left(0.032-0.08y+0.08y\right)[/tex]

[tex]192=6000\left(0.032\right)[/tex]

[tex]192=192[/tex]

Since LHS=RHS and the equation is free from the variable y, therefore the given equation is true for all real values of y.

Hence, all real values of y are solutions.

The edge of the wall would be the center of the wall minus the center of the painting:

7 - 1 = 6 feet.

There should be 6 feet on each side of the painting.
