Answer:

A pound of apples cost 3/4 of a dollar. How much do 5 pounds cost?

Step-by-step explanation:

Essentially you are buying 3/4s of 5 somethings. Since buying a partial of an object is not so common, we will do the inverse, where you buy 5 things, worth 3/4 of something

Answer:  See explanation:  10, 1, 1, -7

Step-by-step explanation:

I'll assume you are working with Excel.  The Product function multiplies all the cells given in the specified range.  Here, those are cells A2 through A5.  As presnted, this would be [10*5*0*(-7)] = 0, which is the value of cell B2.  If we want cell B2 to be -70, we must change one or more of the numbers in cells A2 to A5.

Initial:     10, 5, 0, -7   B2=0

Change:  10, 1,  1, -7   B2 = -70

Other combinations are possible.

Answer:

f(0) = -1, f(1) = 2, f(2) = 5.

Step-by-step explanation:

f(0) = 3(0) - 1 = -1

f(1) = 3(1) - 1 = 2

f(2) = 3(2) - 1 = 5

The value of the function f(x) = 3x + 1 at x = 0, 1, and 2 will be 1, 4, and 7, respectively.

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The function is given below.

f(x) = 3x + 1

The value of the function at x = 0 will be

f(0) = 3(0) + 1

f(0) = 0 + 1

f(0) = 1

The value of the function at x = 1 will be

f(1) = 3(1) + 1

f(1) = 3 + 1

f(1) = 4

The value of the function at x = 2 will be

f(2) = 3(2) + 1

f(2) = 6 + 1

f(2) = 7

The value of the function f(x) = 3x + 1 at x = 0, 1, and 2 will be 1, 4, and 7, respectively.

k= -9

Step-by-step explanation:

2k-3=9k+63-3     [expand the 9(k+7) first]

2k-9k=63-3+3     [put the like terms together]

-7k=63                 [do the simple math]

k= 63 ÷ by -7

k=-9  

Answer:

K = -9

Step-by-step explanation:

2k-3 = 9(k+7)-3

2k-3 = 9k+63-3

2k-3 = 9k+60

2k-9k = 60+3

-7k = 63

-k = 9

k = -9

Answer:

15.30 per hour

Step-by-step explanation:

The hourly rate for Mr Frasier will be $15.30.

The mathematical expression combines 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 denote the logical syntax's operation order and other properties.

Given that Mr Frasier worked her 40 regular hours last week, plus 4 overtime hours at the double-time rate. Her gross pay was $734.40.

The hourly rate will be calculated as:-

Rate = 40 + 2 x 4 = 734.40

Rate = 40 + 8 = 734.40

Rate = 734.40 / 48

Rate = $15.3

The hourly rate is $15.3.

Answer:

each bus carries 22 students

each van carries 14 students

Step-by-step explanation:

1v+3b=80

14v+b=218

eliminate b by multiplying the bottom equation by 3.

(42v+3b=654)-(1v+3b=80)=

41v=574

divide both sides by 41

v=14 (each van carries 14 students)

substitute the value of v into either of the og equations

1(14)-14+3b=80-14

3b=66

divide both sides by 3

b=22 (each  bus carries 22 students)

Answer:

(-3, 6)

Step-by-step explanation:

Solve x - 2 > -5 for x as follows:  Add 2 to both sides, obtaining x > -3.  To graph this, find -3 on the number line and put a circle there.  Draw a solid line from this circle towards the right.

Solve x - 2 < 4 for x as follows:  Add 2 to both sidees, obtaining x < 6.  Find 6 on the number line and put a circle there.  Draw a solid line from this circle to the left.

Notice that the two lines you've drawn overlap on the interval (-3, 6).  This is the desired solution set.

Answer:

3.5x10³

Step-by-step explanation:

7x10^5=700000

2x10^2=200

Divide both by 100

7000÷2=3500

divide by 1000 as standard form is less than 10

1000 is 10 cubed

3500÷1000 is 3.5

∴3.5x10^3 is answer
