Evaluate the expression when a =3 and c= 12.
I need help

Answers

Answer:

Step-by-step explanation:

What is the equation?

You need to replace all A with 3 and all c with 12. If I had the equation, I'd be glad to help further.

For the given values a=3 and c=12 the required expression is 4a-c=0.

What is an equation?

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

Given that,

The value of a = 3         (1)

And the value of c = 12       (2)

To determine the expression,

divide equation (1) and equation (2),

a/c = (3/12)

⇒a/c = 1/4

⇒4a=c

⇒4a-c = 0

The required expression is 4a-c=0.

Jim will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $ 59 and costs an additional$0.13 per mile driven. The second plan has an initial fee of $46 and costs an additional 0.17 per mile driven.

Answers

Answer:This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:

Plan I: Y=38+0.11X

Plan II: Y=49+0.07X

When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25

Are the ratios 4:6 and 6:9 equivalent?

Answers

Answer: No

Step-by-step explanation:

Yes, the two ratios 4:6 and 6:9 are equal to 2:3.

What is a ratio?

A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six.

Given that there are two ratios 4:6 and 6:9. The equivalence of the two ratios will be calculated as:-

4 : 6 = ( 2 x 2 ) ÷ ( 2 x 3 )

4 : 6 = 2 : 3

6:9 = ( 2 x 3 ) ÷ ( 3 x 3 )

6: 9 = 2 : 3

4 : 6 = 6:9 = 2:3

Therefore, the two ratios 4:6 and 6:9 are equal to 2:3.

Can you help me understand front end and clusters when u round​

Answers

Answer:

I really hope this help! Some may call it front end rounding while others call is front end estimating, even though they mean the same thing. When rounding a place value, you need to look to the number to the right of it. Example: Most often a teacher may as you round the number 452 to the nearest ten’s. That number will than be 450. But why? Well as we look at the number, we know we need to round to the nearest ten. So in our case it would be 52. Our rule to remember when rounding is 5 and higher we round-up. Since we are looking at the portion of the number 52, we go right of the tens place to find the number 2. Since the number 2 is not 5 or higher, we round down making it 50. Don’t forget to finish the problem by adding the hundreds back to the original number. Your answer for this problem is 450.

Joel spent $28 for an Internet data service
and
pays $14.50 per month. He spent 524 50 to join
an online movie streaming site and bays $13.25
per month. Write an expression to represent
Joel's total cost for both memberships after
m months

Answers

Answer:

28+14.50+524.50+13.25=  580.25

Step-by-step explanation:

Add it all together.

The expression that represents the total cost for both the membership after m months is

552.50 + 27.75m

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Internet service:

Charges = $28

Monthly pay = $14.50

Total cost after m months.

= 28 + 14.50m

Movie streaming:

Joining = $524.50

Monthly charge = $13.25

Total cost after m months.

= 524.50+ 13.25m

The total cost for both memberships after m months.

= 28 + 14.50m + 524.50 + 13.25m

=  552.50 + 27.75m

Thus,

The total cost is 552.50 + 27.75m.

y_mid = 1

x_mid = -1

y2= 4

x2 = 2

Solution

(2 + x1)/2 = -1

(2 + x1) = -1 * 2

2 + x1 = -2

x1 = -2 -2

x1 = - 4

what is 6 1/8 as a decimal?

Answers

Answer:

6.125

Step-by-step explanation:

1/8 is half of 1/4.

1/4 is 0.25

0.25 / 2 = 0.125

6 + 0.125 = 6.125

The mixed fraction 6 1/8 as a decimal form is 6.125.

The correct option is C.

To convert the mixed number 6 1/8 to a decimal, you can follow these steps:

Step 1: Multiply the whole number (6) by the denominator (8): 6 × 8 = 48.

Step 2: Add the numerator (1) to the result from step 1: 48 + 1 = 49.

Step 3: Write the sum from step 2 as the numerator over the original denominator: 49/8.

Step 4: Divide the numerator (49) by the denominator (8): 49 ÷ 8 = 6.125.

Therefore, 6 1/8 as a decimal is 6.125.

The decimal form of a mixed number represents the sum of the whole number and the fraction converted to decimal form. In this case, 6 represents the whole number part, and 1/8 represents the fraction part. By performing the division, you find that the fraction 1/8 is equivalent to the decimal 0.125. Adding this decimal to the whole number 6 gives the final result of 6.125.
