Answer:

30.60

Step-by-step explanation:

Hundredths Place is two places after the decimal point

since 9 is greater than 5 you move up, so 5 turns to a 6

so 30.599 ≈ 30.60

Answer:

30.6

Step-by-step explanation:

the hundredth in 30.599 is the bold since 9 is greater than 9 you will regroup 1 to the tenths place to get 30.6

Answer:

Yes

Step-by-step explanation:

If they are the same linear equation, there would be infinite solutions. IT would look like:

The Equivalent Expression is 12 + 12x + 6y.

Therefore, option A is correct.

In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows: (Number/variable, Math Operator, Number/variable) is an expression.

We have the expression: 6(2 + x + x + y)

Using Distributive property

a x ( b + c + d) = ab + ac + ad

So, the simplified expression is

= 6(2 + x + x + y)

= 6(2) + 6(x) + 6(x)+ 6(y)

= 12 + 6x + 6x + 6y

= 12 + 12 x + 6y

So, the Equivalent Expression is 12 + 12x + 6y.

Answer:

-4

Step-by-step explanation:

-4b + 2 = 18

subtract 2 from 18

-4b = 16

divide -4 by -4

divide 16 by -4

b = -4

Answer:

Given that speed(v) = 20km/h and time(t) = 50 min

We have to find distance (d)

First convert speed into m/s

v = (20*1000m)/(1*3600s)

v = (50/9) m/s

Now convert time into second

t = 50*60 = 3000 sec

As we know that

d = v*t = (50/9)*3000 = 50000/3

d = 16666.67m or 16.67km

Ans: 16666.67m or 16.67km

Answer:

2.24%

Step-by-step explanation:

Given that :

Actual height = 68.5

Measured height = 67

Percentage error :

(Error value / True value) * 100%

Error = Actual - observed = (68.5 - 67) = 1.5

Percentage error :

(1.5 / 67) * 100%

0.0223880 * 100%

= 2.2388%

= 2.24%

Answer: 7/8

Step-by-step explanation:

You can change all the fractions to have equivalent denominators.

The Least Common Denominator of 1 1/4 and 3/8 is 8. Now we can change the fractions.

1 1/4 = 1 2/8 = 10/8.

3/8 = 3/8.

Now we can subtract. Subtract the numerators of the first fraction from the numerators of the second fraction, and the denominators oft he first fraction to the denominators of the second fraction.

10/8 - 3/8 = 7/8.

Therefore, 1 1/4 - 3/8 = 7/8; the fourth answer.

Answer:

A. The area of a rectangle is equal to all the areas of the small rectangles. The dimensions of the small rectangles are 2a, 3a, and 4a. If you add those areas up, 2a+3a+4a equals the area of the large rectangle.

B. The area of a rectangle equals the width and height. The height of the large rectangle is already shown in the picture, a. The width is seperated into three portions, 2, 3, and 4. To find the total width, add 2+3+4. Now, multiply the width by the height to calculate the area. (2+3+4)a
