Answer:

d = 2

Step-by-step explanation:

8 - 2 = 6

6 / 3 = 2

plz mark brainliest

Answer:

d=2

Step-by-step explanation:

Switch the left and right sides

2+3d=8

Rearrange the expression

3d+2=8

Separate the constants and variables

3d=8−2

Add or subtract the numbers

3d=6

divide both sides by 3

3d/3=6/3

d=2

hope it helps :)

Answer:

mechnical energy

Step-by-step explanation:

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

2=3 being the opposite angle

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

7 thousands = 7,000

70 hundreds = 7,000

These two numbers are both equivalent.

They both give a total of 7,000.

Answer:

3

Step-by-step explanation:

Just count how many terms are there in the expression

Answer: 7.2

The 2 in the number 7.32 is in the tenths place.

We must move it to the hundredths place, 1 step forward.

You get a number of 7.2. The answer can be 7.2.

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.  

Answer:

I) Eq(1) reason: sum of segments of a straight line

II) Eq(2) reason: Given PQ = ST & PS = RT

III) Eq(3) reason: sum of segments of a straight line

IV) Eq(4) reason: Same value on right hand sides of eq(2) and eq(3) demands that we must equate their respective left hand sides

V) Eq(5) reason: Usage of collection of like terms and subtraction provided this equation.

Step-by-step explanation:

We are given that;

PS = RT and that PQ = ST

Now, we want to prove that QS = RS.

From the diagram, we can see that from concept of sum of segments of a straight line we can deduce that;

PQ + QS = PS - - - - (eq 1)

Now, from earlier we saw that PQ = ST & PS = RT

Thus putting ST for PQ & PS for RT in eq 1,we have;

ST + QS = RT - - - - (eq 2)

Again, from the line diagram, we can see that from concept of sum of segments of a straight line we can deduce that;

RS + ST = RT - - - - -(eq 3)

From eq(2) & eq(3) we can see that both left hand sides is equal to RT.

Thus, we can equate both left hand sides with each other to give;

ST + QS = RS + ST - - - (eq 4)

Subtracting ST from both sides gives;

ST - ST + QS = RS + ST - ST

This gives;

QS = RS - - - - (eq 5)

Thus;

QS = RS

2.7 is the correct answer

Step-by-step explanation:

Answer:

2.7

Step-by-step explanation:

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.

Answer:

y-4=3/2(x+4)

Step-by-step explanation:

If you plug the numbers into the equation (y-y1=m(x-x1)), you get y-4=3/2(x+4).

Answer: y=3/2x+13

Step-by-step explanation: y-4=3/2(x-(-6))

y-4=3/2x+9

y=3/2x+13

Answer:

look for the LCM of all the denominators, devide the denominators by the LCM and add the numerators( don't forget the signs ), then add and subtract your answers ( by this time the LCM becomes the denominator and the answer from th subtraction and addition of the numerators becomes the present numerator ), then reduce to lowest term the answer gotten
