What is the sum1,000+2,000=

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable (a letter), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

So the terms are 9a, 4b, and 18.

hope it helps!

Answer:

Step-by-step explanation:

For the terms of the expression , Sally has to write coefficients with the variables

Answer:

less

Step-by-step explanation:

We assume price of a shirt is $100.

Initially price is increased by 10%: 100+10=110

Then it is reduced by 10%: 110-11=99

Now price of a shirt is $99.

Answer is price of a shirt is less than it was at the start.

After 2 years she will have earned $12 * 2*2.3% = $12* 4.6% = 55c interest (to the nearest cent). Therefore the balance will be $12.55

After 6 years she will have earned $12 * 6*2.3% = $12* 13.8% = $1.66 interest (to the nearest cent).  

Therefore the balance will be $13.66

After 10 years she will have earned $12 * 10*2.3% = $12* 23% = $2.76 interest (to the nearest cent).  

Therefore the balance will be $14.76

Answer: c = -0.98

Step-by-step explanation: Differential equation of first order is an equation involving differentiable function and its derivative.

For the differential equation: [tex]xy' +2y=4x^{2}[/tex], it given a solution function:

[tex]y=x^{2}+cx^{2}[/tex]

Factorating the function: [tex]y=x^{2}(1+c)[/tex]

So, to determine constant c, use the initial condition:

When x = 10, y = 2:

[tex]2=10^{2}(1+c)[/tex]

[tex]1+c=\frac{2}{100}[/tex]

[tex]1+c=0.02[/tex]

c = -0.98

Constant c that satisfies the initial condition is c = -0.98

Answer:

SF = 39

Step-by-step explanation:

If you have negative numbers anywhere in the set, then that set cannot be part of the whole numbers or natural numbers. This is because

set of whole numbers = {0,1,2,3,4,5,...}

set of natural numbers = {1,2,3,4,5,...}

The only difference is that 0 is not included in the set of natural numbers. Neither set has negative values in them.

So for instance the set {-5, 1,2,7} involves a number that is neither part of the whole numbers or natural numbers set. But every item listed is an integer

set of integers = { ..., -3, -2, -1, 0, 1, 2, 3, ... }

We can see that the integers is the set of positive and negative whole numbers, with 0 as well

Answer:

All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.

Answer:

5 x 3 = 15

Step-by-step explanation:

x15 = 3 is impossible, because if you multiplied anything by 15 you wouldn't get 3.

Answer:

-9h² - 12h - 3

Step-by-step explanation:

Follow the FOIL method:

FOIL = First, Outside, Inside, Last

Multiply the terms together:

First: 9h * -h = -9h²

Outside: 9h * -1 = -9h

Inside: 3 * -h = -3h

Last: 3 * -1 = -3

Combine like terms: 9h² + (-9h - 3h) - 3

9h² - 12h - 3

-9h² - 12h - 3 is your answer.

Answer:y=-5x-2

Step-by-step explanation:

Answer:

x=5 y= -7

Step-by-step explanation:

y= -3x +8

-(y= -5x -2)

=> y=-3x+8

-y=5x+2

=> 0=2x+10

=> x=5

=>y=-3(5)+8

=> y= -7

n = - 99

- 213 + n = - 312

n = - 312 + 213

n = - (312 - 213)

n = - 99

Answer:

- 51

Step-by-step explanation:

Order of operations. What's in the parenthesis is first.

4 + 3 ( 7+4 x 2) - 100  

Concentrate on (7 + 4 x 2 ) first.

We multiply first so 4 x 2 = 8  then we add.

(7 + 8) = 15

4 + 3(15) - 100    Again, we multiply first.

4 + 45 - 100      Now we can add and subtract in any order.

49 - 100 = - 51

Answer: Try 6

Step-by-step explanation:

The value of segment DF will be 8 units.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.

The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that the points C, D, E and F all lie on the same line segment, in that order, such that the ratio of CD: DE: EF is equal to 3 : 2: 6. If CF = 11. The value of DF will be calculated as below:-

3x + 2x + 6x = 11

11x = 11

x =1

DF = 2x + 6x

DF = 2 + 6

DF = 8

Therefore, the value of segment DF will be 8 units.

Answer:

P(nickel or dime) = 3/4

Step-by-step explanation:

First, find the total amount of coins that there are:

6 + 14 + 16 + 4 = (20) + (20) = 40

You are trying to find P(nickel or dime). Note that there are 14 nickels, and 16 dimes. Add these two numbers together:

P(Nickel or dime) = (14 + 16)/40

P(Nickel or dime) = (30)/40

Simplify. Divide common factors from both the numerator & denominator (10)

P(Nickel or dime) = (30/40)/(10/10) = 3/4

P(nickel or dime) = 3/4

Answer:

Step-by-step explanation:

We can add the fractions together to compare with how much sugar she needs.

[tex]\frac{1}{2}+\frac{2}{5}=\frac{5}{10}+\frac{4}{5}=\frac{9}{10}[/tex]

So Juvi has [tex]\frac{9}{10}[/tex] cups of sugar.

She needs [tex]\frac{2}{3}[/tex] cups, so let's make the denominators the same and compare.

[tex]\frac{2}{3}=\frac{20}{30}[/tex]

[tex]\frac{9}{10}=\frac{27}{30}[/tex]

Since [tex]\frac{27}{30}[/tex] > [tex]\frac{20}{30}[/tex], she has enough sugar to make 4 batches of brownies.

Hope this helps.
