Answer: A

One solution    x = 60/23   y=12/23  z= -72/23

How?    in the photos attached

Step-by-step explanation:

Take the first equation and rewrite

5x +y = 1  becomes  y = 1 -5x

Substitute for y in the second equation  

Solve for x

The rest of the steps are more of the same: substitute and solve as scownin the photos

Just count how many terms are there in the expression

Answer:

C. -11

Step-by-step explanation:

f(x) = -2x - 5

Plug the 3 in for x

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

Multiply the -2 and 3

f(3) = -6 - 5

Subtract 5 from -6

f(3) = -11

Answer: C -11

Step-by-step explanation:

Its asking you to solve for f(x) which is Y

Y=-2x-5

X is 3

so replace -2x with 3 but only the x

you should get -23 not negative 23 its more of 2 times 3

then multiply -2 by 3 and get -6

add -6 and -5 to get -11

Given expression:

             A  = [tex]\frac{1}{2}(b_{1} + b_{2} )[/tex]

Solve for b₁;

  Solution:

This is a subject of the formula problem.

  Given expression:

               A  = [tex]\frac{1}{2}(b_{1} + b_{2} )[/tex]

First, multiply both sides by 2;

          2 x A  = 2 x [tex]\frac{1}{2}(b_{1} + b_{2} )[/tex]  

              2A  = b₁  + b₂

Then subtract b₂ from both sides;

           2A - b₂ = b₁ + b₂ - b₂

                 b₁ = 2A - b₂

The solution is   b₁ = 2A - b₂

Answer:

A. 0.9510

B. 0.0480

C. 0.0490

D. No, I would not feel comfortable accepting the shipment if one item was found defective, because the probability is quite small to obtain 1 or more defective items.

7 thousands = 7,000

70 hundreds = 7,000

These two numbers are both equivalent.

Answer:

1: m=2

2: g=7

3: y=13

4: a=-27

5: x=15

6: w=-18

Answer:

1. m = -2  

2. g = 7  

3. y = 13      

4. a = -36  

5. x = 15

6.  w = -18                                                                                                                                            

Step-by-step explanation:

1. Make the constant to the right-hand side and change its sign

a = 10 - 12

Calculate the difference a = -2

Solution

a = -2

2. Move variable to the left-hand side and change its sign

-g - 2 = - 9

Move constant to the right-hand side and change its sign

-g = -9 + 2

Calculate the sum

-g = -7

Change the signs on both sides of the equation

g = 7

Solution

g = 7

3. Divide both sides of the equation by - 7

-7y ÷ (-7) = -91 ÷(-7)

Any expression divided by itself equals 1

y = 91 ÷ (-7)

Divide two negatives equals a positive: (-) ÷(-)=(+)

y = 91 ÷ 7

Calculate the quotient

y = 13

Solution

y = 13

4. Multiply both sides of the equation by 9

9 x a/9 = 9 x (-4)

Reduce the number with the greatest common factor 9

a = 9 x (-4)

Multiply a positive and a negative equals a negative: (+)x(-)=(-)

a = -9 x 4

Multiply the numbers

a = -36

Solution

a = -36

5. Multiply both sides of the equation by 3/2

3/2 × 2/3x =  3/2 × 10

Reduce the numbers with the greatest common factor 3

1/2 × 2x = 3/2 × 10

Reduce the numbers with the greatest common factor 2

x = 3/2 × 10

Reduce the numbers with the greatest common factor 2

x = 3 x 5

Multiply the numbers

x = 15

Solution

x = 15

6. Multiply both sides of the equation by 9/4

9/4 x 4/9w = 9/4 x (-8)

Reduce the numbers with the greatest common factor 9

1/4 x 4w = 9/4 x (-8)

Reduce the numbers with the greatest common factor 4

w = 9/4 x (-8)

multiplying a positive and a negative equals and negative: (+)x(-)=(-)

w = -9/4 x 8

Reduce the numbers with the greatest common factor 4

w = -9 x 2

Multiply the numbers

w = -18

Solution

w = -18

Answer:

$38,640.00

Step-by-step explanation:

We know that Catrina earns $19.32 an hour. We also know she works 40 hours a week. So first, let's multiply 19.32 by 40 to see how much she makes a week.

19.32 × 40 = 772.80

Because of this, we now know that Catrina makes $772.80 a week. There are 52 weeks in a year. However, since she takes 2 weeks of vacation, we need to take off 2 weeks in the year. This leaves us with 50.

Finally, we multiply 772.80 and 50 to find her annual earnings:

772.80 × 50 = 38640

Therefore, her annual earnings will be $38,640.00.

Step-by-step explanation:

A geometric figure has rotational symmetry if the figure appears unchanged after a rotation about a point by an angle that is between 0° and 360°. 0° and 360° are excluded since they represent the original position, nothing new happens. The angles of rotational symmetry will be factors of 360.

Step-by-step explanation:

30% can be rewritten as 0.30, which happens to be where point s falls, on the third mark between 0 and 1.

Answer: T

Step-by-step explanation:

Idk if this is true but if you're looking for 30% on one, you'd want to count the total amount of spikes before number one. There are 10, so you can probably infer that 30% of 10 is 3, making it T.

Answer:

$898

Step-by-step explanation:

Based on Joey's debt-to-income ratio, the maximum monthly rent payment he can make and still maintain the DTI ratio is b. $898.

Joey has a DTI ratio of 36% which means that his maximum debt payment should be 36% of his income. This amount would be:

= DTI x monthly income

= 36% x 3,600

= $1,296

This can be found as:

= Maximum monthly debt payment - Car payment - Credit card payment

= 1,296 - 178 - 220

= $898

In conclusion, option B is correct.

Step-by-step explanation:

Answer:  Converse: If the candy has 350 calories, the candy is chocolate, False. There is another 350 calorie candy.

Inverse:  If the candy does not have 350 calories, the candy is not chocolate. True In this case, the evidence in the chart supports this. The inverse is not always true.

Contrapositive: If the candy does not have 350 calories, the candy is not chocolate. True   The evidence in the chart supports this statement, and the Contrapositive is generally considered a logical equivalent of the original.

Step-by-step explanation:

You need to have a basic frame for converting the original statement to the other forms such as

Original: If P, then Q

Converse: If Q, then P      Just reverse the parts

Inverse: If not P then not Q In the same order, make both negative, add "not"

Contrapositive: If not Q then not P Reverse the order of the original and make both negative.
