Answer:

-8

Step-by-step explanation:

3x4= 12, 7+3=10x2=20

12-20= -8

Answer:

The value of the expression is -8

Step-by-step explanation:

Numerical value of expressions

We are given the expression:

3x - 2(y + 3)

Let's find its value for x = 4 and y = 7.

Substituting both values into the expression:

3*4 - 2(7 + 3)

Operating:

12 - 2(10)

12-20

-8

The value of the expression is -8

Answer:

Step-by-step explanation:

If we have odd number of consecutive numbers increasing by the same value (2) then the middle value of them is their mean:

220:5 = 44

Of course you can find them to be sure:

Consecutive even integers increase by 2.

So if 2x is the smallest of them (x is an integer), then the numbers are:

2x,  2x+2,  2x+4,  2x+6,  2x+8

So their sum:   10x+20

10x + 20 = 220  ⇒  10x = 200  ⇒  2x = 40

So the numbers are: 40, 42, 44, 46, 48

Answer:

44

Step-by-step explanation:

given the total amount at hand is $25

let the price of  candy be x

then the cost of 3 candy will  be 3x

the cost of a candy snake is $12.50.

balance at hand after the end of buying $8.75

the total expenses summed up must equal the initial amount at hand which is $25

the expression for the scenario is 3x+12.5+8.75=25

3x+21.25=25

3x=25-21.25

3x=3.75

x=3.75/3

x=$1.25

The cost of a candy is $1.25

Answer:

14

Step-by-step explanation:

$25.00 - $4.00 = $21.00

$21.00 / $1.50 = 14

Answer:

14 ride tickets

Step-by-step explanation:

He has $25, and spends $4. So 25 - 4 = 21. Each ride ticket is $1.50. So 21 ÷ 1.50 = 14

Answer:

1.66

Step-by-step explanation:

The years needed to make $3000 to $5000 is 12.5.

Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.

Given that, an investment of $3000 to amount to 5,000 if money is invested at 4.1% compounded monthly

A = P(1+r/12)^12t

5000 = 3000(1+0.041/12)^12t

5/3 = (1.0034)^12t

Taking log both sides,

log5/3 = 12tlog(1.0034)

0.221 = 12t0.00147

12t = 150.34

t = 12.5

Hence, required years are 12.5.

Answer:

Cluster Random Sample

Step-by-step explanation:

The operating rooms were divided into (hospital locations) and inspectors sampled every operating room from some of the groups.

Sampling method is the method where the subset of an overall population is selected.

The sampling method used was cluster sampling

From the question, we understand that:

The above illustrates cluster sampling.

This is so because, cluster sampling involves breaking down a population into smaller size.

In this case, the smaller size are the locations that were selected.

Answer:

Step-by-step explanation:  

let x be the number of refils

also given is that the cost of one refill is $1.25

hence the total refil will be 1.25x

given that the cost of a mug is $6.75

6.75+1.25x=31.75

therefore  the expression that can be used to solve for the number of refills is

6.75+1.25x=31.75

Answer:

(0,3)

Step-by-step explanation:

just a guess C;

The point that satisfies both the inequalities is (0, 3).

Correct option is (C).

Inequalities are mathematical formulas in which neither side is equal.

As per the given data:

We are given two inequalities, and we have to find out whether the points that are given in the options are satisfying the solution set of the given inequalities or not.

The inequalities are as follows:

x + y > 2

4x + y ≥ -1

For option (A). (2, 0)

Substituting the points in the given inequalities.

2 > 2 and 8 ≥ -1

Hence, this is incorrect.

For option (B). (0, 2)

Substituting the points in the given inequalities.

2 > 2 and 2 ≥ -1

Hence, this is incorrect.

For option (C). (0, 3)

Substituting the points in the given inequalities.

3 > 2 and 3 ≥ -1

Hence, this is correct.

For option (D). (0, -1)

Substituting the points in the given inequalities.

-1 > 2 and -1 ≥ -1

Hence, this is incorrect.

Hence, The point that satisfies both the inequalities is (0, 3).

Answer:

10 [tex]\frac{1}{8}[/tex] = [tex]\frac{81}{8}[/tex]

Step-by-step explanation:

Given

(m - 10)(8m - 1) = 0

Equate each factor to zero and solve for m

m - 10 = 0 ⇒ m = 10

8m - 1 = 0 ⇒ 8m = 1 ⇒ m = [tex]\frac{1}{8}[/tex]

Thus sum of roots = 10 + [tex]\frac{1}{8}[/tex] = 10 [tex]\frac{1}{8}[/tex] = [tex]\frac{81}{8}[/tex]
