Answer:

6x-6

Step-by-step explanation:

First you use the order of operations and multiply 4(x)+4(-2)=4x-8 and then 2(x)+2(1)=2x+2. Then you add it all together, 4x+2x+2-8=6x-6.

Step-by-step explanation:

1/4=2/8

2/8+3/8=5/8

Answer:

5/8

Step-by-step explanation:

3/8 + 1/4

1/4 x 2 = 2/8

3/8 + 2/8 = 5/8

Answer:

If x = -2, -1, 0, 1, then (In this order) y = 7, 5, 3, 1

Step-by-step explanation:

If you put in each value of "x" into the equation, you'll get the appropriate "y".

y= -2(-2)+3

y= 4+3

y= 7

y= -2(-1)+3

y= 2+3

y= 5

y= -2(0)+3

y= 0+3

y= 3

y= -2(1)+3

y= -2+3

y= 1

Answer:

Approx. 2.2 miles

Step-by-step explanation:

Convert 2/3 to a decimal, (.66)

Then, add it to the number 6. (6.6)

Divide the 6.6 miles by 3= 2.2.

Approx 2.2 miles a day

Answer:

960

Step-by-step explanation:

We know that 4 percent of 800 dollar is 32 dollar. So 32 time 5 (because it ask us how much after 5 year) is 160. Now we add it to 800 because it ask  the total in his account so it 960.

After five years, Rajeev have $960 in his account.

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

We have to given that;

Rajeev deposits $800 in a savings account earning interest at a rate of 4% compounded annually.

Here, Principal amount = $800

Rate = 4%

Time = 5 years

Hence,

Interest = PRT/100

            = 800 x 4 x 5 / 100

            = 160

Thus, Total amount after 5 years is,

⇒ 800 + 160

⇒ $960

Therefore, After five years, Rajeev have $960 in his account.

Step-by-step explanation:

Answer:

-22 ft.

Step-by-step explanation:

So we know that the diver descends (goes deeper) at a rate of 2 feet per second.

We also know that he/she is already at an elevation of -8 feet.

The first we need to do to solve this question is to find out the number of feet the diver descends in 7 seconds:

We do this by multiplying the amount of time by the number of feet (7 x 2)

as we all know 7 x 2 = 14 feet

So the diver dove deeper by 14 feet.

Now we have to add 14 and 8 to find the divers new elevation:

14 + 8 = -22 ft.

The divers' elevation after descending for 7 seconds is -22 ft.

plz mark me brainliest if correct :)

The diver's elevation after she descends for 7 seconds will be -22 ft.

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

It would be -2.

Step-by-step explanation:

Key skills: Conjugate, Distribution Property, and Addition/Subtraction

3 + [tex]\sqrt{11\\}[/tex] is your expression. The conjugate is an important concept you need to know to solve this.

Given the expression: [tex]a + \sqrt{b\\}[/tex]

It's conjugate would be: [tex]a - \sqrt{b}[/tex]

(Basically if there is an addition sign between the 2 terms, it would become a subtractions symbol and if there is a subtraction symbol it would become an addition symbol)

1) So the conjugate of  [tex]3+ \sqrt{11}[/tex] would be [tex]3 - \sqrt{11}[/tex]

2) Now we would have to multiply them

Answer:

The probability model is

= P(A or B)

Step-by-step explanation:

a) Data and Calculations:

Estimated revenue if the day is sunny = $3,000

Estimated loss if the day is rainy = $600

The probability of rain = 30%

Therefore, the probability of sunshine = 70% (100 - 30)

The probability model is based on the probability of rain or sunshine

= P(A or B)

= A*70% - B*30%

The outcome from either rain or sunshine

= ($3,000 * 70%)  -($600 * 30%)

= $2,100 - $180

= $1,920
