In the expression 12a+5, identify. The coefficient

Answers

Answer 1

Answer: A coefficient is a number multiplied by a variable.

In this case, our variable is a.
The coefficient is 12.

(PS: The +5 that isn't being multiplied by a variable is called a constant)

Which is greater 74.3 or 7.43

Answers

Perhaps the question will be less confusing if you temporarily ignore the decimal parts, and just compare the whole-number parts.

Look at 74 , and then look at 7 .
Look at them again, and a few more times if necessary.
You'll see that 74 is waaay bigger than 7 .

That's true even when you stick the decimal parts back on.
The decimal parts can't change it ... a decimal part can't
add more than ' 1 ' to a whole number.

So 74 (plus any decimal) is still waaay bigger than 7 (plus any decimal).

74.3 is greater because it is 10 times greater than 7.43.

660 is 10 times as much as 600 true or false

False. 660 is not 10 times as much as 600. It is 10 times as much as 66, because everything has moved left in the place value column by one step.

Ginny has 16 chocolate bars. She gives away ¾ of her chocolate bars to friends. How many chocolate bars did Ginny give away? Record your answer as an improper fraction (fraction greater than one) or a whole/mixed number.

Answers

Answer:

She gave away 12, so she still has 4.

Step-by-step explanation:

16 times .75 equals 12.

Answer: Ginny gave away 12 chocolate bars

Step-by-step explanation: if 16 is 4/4, and 16/4=4, then you multiply 4x3 to figure out that 3/4=12/16

Solve -0.5(–2x+8) – 8 = 8.

Answers

Answer:

x = 20

Step-by-step explanation:

Firstly, we have to distribute: (-0.5 * -2x) and (-0.5 * 8) -8 = 8

1x - 4 - 8 = 8

Next collect like terms: 1x - 12 = 8

Isolate x to get the value of x: Add 12 to both sides

1x = 20

So x = 20

Answer:x=20

Step-by-step explanation: first you distribute the value outside of the parentheses

-0.5*2x= 1x

-0.5*8=-4

it then becomes

x-4-8=8

combine -4 and -8

x-12=8

add the 12 over

x=20

Gabriel used 1/3 of a liter of milk to make 1/9 of a jug of tea. How much milk is required to fill the jug?

Answers

The volume of milk required to fill the jug is 3 Liters

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Volume of milk used = 1 / 3 liter

The volume of jug = 1 / 9

And the volume of milk required to fill the jug is calculated by

Let the volume of milk required be A

1/3 liters of milk = A x 1/9 volume of jug of tea

So,

To fill 1 volume of jug of tea , multiply both sides by 9 , so we can calculate the volume of milk required to fill the jug

A liters of milk = 9 x 1/3 liters of milk

A liters of milk = 3 liters of milk

Hence , the volume of milk required is 3 Liters

Carla and Frank can each wash a car and clean the interior in 2 hours, but Missy needs 3 hours to do the work. If the three work together, how long will it take to clean 7 cars?

Answers

Remark

Start by figuring this out for 1 car. Worry about the 7 part when you find 1.

This problem is used quite frequently in physics. For example resistors in parallel use the same equation.

Formula

1/frank + 1/carla + 1/missy = 1/ time taken to do 1 mar.

Givens

Frank = 2 hours

Carla = 2 hours

Missy = 3 hours.

Substitute and Solve

1/2 + 1/2 + 1/3 = 1/Three_together.

3/6 + 3/6 + 2/6 = 1/Three_together.

8/6 = 1/Three_together. Cross multiply

8 * Three_Together = 6*1

8 * Three_Together = 6 Divide by 8

Three_Together = 6/8 = 3/4 = 0.75 hours. or 45 minutes for 1 car

Seven Cars

For 7 cars multiply 0.75 by 7

7 * 0.75 = 5.25 hours. <<<< Answer
