It is 2.1 km from Mary's house to the nearest mailbox. How far is it in meters?
It is 2.1 km from Mary's house to the nearest mailbox.
To Find:How far is it in metres.
Conversion:1 km = 1,000 m
2 km = 2 × 1,000 = 2,000 m
Solution:2.1 km = ( 2,000 + 100 ) m = 2,100 m
Answer:2,100 m
Therefore, It is 2,100 metre far away from Mary's house.
Solve the equation 1/4 (x+2)+5=-x
Answer:
Exact Form:
x=−225
Decimal Form:
x=−4.4
Mixed Number Form:
x=−4 2/5
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
1/4 (x-2) + 5 = x
1/4 (x-2) = x - 5
x - 2 = 4(x-5)
x-2 = 4*x + 4*-5
x-2 = 4x - 20
x - 4x = 2 - 20
-3x = -18
x = -18/-3
x = 6
Check:
1/4(6-2) + 5 = 6
1/4(4) + 5 = 6

Savannah's balance in her checking account was –$638.57. She deposited two checks, each in the amount of $298.40. What is Savannah’s new checking account balance after the deposits?
Answer:
$-41.77
Step-by-step explanation:
$298.40 multiplied by 2 is $596.8, since Savannah added 2 deposits.
Now we add that to the current balance, -$638.57, to get an answer of $-41.77
Answer:
-41.77
Step-by-step explanation:
Multiply $298.40 by 2 OR add $298.40 + $298.40
either gives you $596.80
Savannah deposited $596.80
You add that to -$638.57

If he has 484 plants and there are as many rows as there are plants in each row, his field is a square.
The area of a square = (side)^2
In this problem,
Area = 484
side = # of rows
Let's plug our values into the formula above
484 plants = (side)^2
Take the sqrt of both sides.
22 rows = side.

A carton has a length of fraction 2 and 1 over 6 feet, width of fraction 1 and 1 over 5 feet, and height of fraction 2 and 1 over 2 feet. What is the volume of the carton?
Answer:
6 1/2 cubic feet
Step-by-step explanation:
A carton has a length of 2 1/6 feet
The width is 1 1/5 feet
The height is 2 1/2 feet
Therefore the volume of the carton can be calculated as follows
= length × width × height
= 2 1/6 × 1 1/5 × 2 1/2
= 13/6 × 6/5 × 5/2
= 390/60
= 13/2
= 6 1/2 cubic feet
Hence the volume of the carton is 6 1/2 cubic feet

If BC = x − 2, CD = 19, and BD = 3x − 11, what is BD? Simplify your answer and write it as a proper fraction, mixed number, or integer. Could you please type the answer in a step by step.
Answer:
UV = 15
BD= 31
Step-by-step explanation:
Since, U is the midpoint of TV.
Therefore,
TU = UV
x + 10 = 3x
x - 3x = - 10
-2x = - 10
x = - 10/-2
x = 5
UV = 3x = 3*5
UV = 15
BD = BC + CD
3x - 11 = x - 2 + 19
3x - 11 = x + 17
3x - x = 11 + 17
2x = 28
x = 28/2
x = 14
BD = 3x - 11 = 3*14-11 = 42 - 11
BD= 31
Please explain how this diagrams works
Answer:
x = 21°
Step-by-step explanation:
opposite angles are equal
therefore, (3x + 1)° = 64°
open the brackets
3x + 1 = 64
3x = 64 - 1
3x = 63
divide both sides by 3
x = 21°
In Seattle, WA, it is said to rain 66% of the time. Since there are 365 days in a year, approximately how many days is it expected To rain?
In a year with 365 days, it should rain for about 240 of those days for the given condition.
What is the percentage?It is the ratio of two integers expressed as a decimal fraction of a whole number. It is a statistic for contrasting two sets of data, and the % sign is used to describe it as a percentage. Percentages are often and creatively used. For instance, a lot of data is published as percentages in the media, including bank interest rates, retail discounts, and inflation rates.
It is supposed to rain 66% of the time in Seattle, Washington. Considering that there are 365 days in a year,
Suppose the number of days is it expected to rain obtained be x,
x=66% of 365
x=66/100 × 365
x=240,9 ≈ 240
Thus, it should rain for about 240 days.

The price of a sweater was reduced from 20$ to 12$. By what percentage was the price of the sweater reduced?
Answer:
60%
Step-by-step explanation:
To find the reduction percentage, divide 12 by 20, then multiply by 100:
12/20
= 0.6
0.6(100)
= 60
So, the sweater was reduced by 60%
Answer:
60%
Step-by-step explanation:
[tex]\frac{12}{20} * \frac{x}{100}[/tex]
12 * 100 is 1200
1200/20 = 60
So, therefore the sweater was reduced by 60%.
Hope this helps, have a great day:)

Answer:
all
Step-by-step explanation:
first we can combine 5x and - 2x
5x + -2x = 3x
now we have 3x + 5 > 11
now we can go through all of the numbers to see which numbers make the inequality true
3 yes
3 * 3 = 9
9 + 5 = 14
so all of the numbers make it true
Answer:
d is the right answer
Step-by-step explanation:

10>11
so b is wrong
3(6)+5-2(6)>11
11>11
c is wrong bc they equal
Describe and correct the error a student made when naming the polynomial
-2x3 + 5x4 - 3x is a
cubic trinomial
+
Choose the correct answer below
O A. The student did not put the polynomial in ascending order of the degrees of the terms before naming it by the first term. It is a linear trinomial.
O B. The student did not combine like terms before naming the polynomial. It is a degree-8 polynomial.
O C. The student did not put the polynomial in standard form before naming it by the first term. It is a fourth-degree trinomial.
OD. The student did not put the polynomial in standard form before naming it by the first term. It is a quadratic trinomial.
Answer:
C. The student did not put the polynomial in standard form before naming it by the first term. It is a fourth-degree trinomial.
Step-by-step explanation:
A trinomial is a polynomial with three variables. The polynomial -2x³ + 5x⁴ - 3x has three variables hence it is a trinomial.
The degree of a polynomial is the highest degree of a variable in a polynomial equation.
The polynomial -2x³ + 5x⁴ - 3x can be arranged as The polynomial 5x⁴ - 2x³ - 3x, hence the variable with the highest degree is 5x⁴ which has a degree of 4.
Therefore The polynomial -2x³ + 5x⁴ - 3x has a degree of 4
This means the polynomial -2x³ + 5x⁴ - 3x is a trinomial with a degree of 4

Is the ordered pair (-3,2) a solution to the equation 5x + 2y = -11
Step-by-step explanation:
(-3,2) is equal to (x,y)
x=-3 so 5x becomes 5x-3.
5x-3=-15
y=2 so 2y becomes 2x2.
2x2=4
-15+4=-11

True
So the answer is Yes, the ordered pair (-3,2) is a solution.
