How do i solve this equation: 4/5a + 3 = 1/3a - 8

Answers

You have to [tex]subtract [/tex] by [tex] \frac{1}{3}a [/tex] on [tex]EACH[/tex] of  the [tex]sides [/tex] you're [tex]working [/tex] with!

[tex] \frac{4}{5}a + 3 - \frac{1}{3}a - 8 - \frac{1}{3}a [/tex]

Which [tex]gives [/tex] us: [tex] \frac{7}{15}a + 3 = -8 [/tex]

[tex]Now, [/tex] that we got these [tex]steps[/tex] out of the way, let's [tex]subtract [/tex] [tex]3[/tex] from the sides you're working with! 

[tex] \frac{7}{15}a + 3 - 3 \\ = -8 -3 [/tex]

 [tex] \frac{7}{15}(a) = -11[/tex]

We have gotten these  [tex]steps [/tex] out of the way now lets [tex]multiply [/tex] by [tex] \frac{15}{7} [/tex] on your [tex]sides[/tex] because, it is the [tex]reciprocal [/tex] of [tex] \frac{7}{15} [/tex]

So,  [tex] \frac{15}{7}( \frac{7}{15}a ) = \frac{15}{7} (-11)[/tex]

Cancel out: [tex] \frac{15}{7}( \frac{7}{15} )[/tex] because, it equals to:[tex]1[/tex]

[tex] \frac{15}{7}(-11) = \frac{-165}{7} [/tex]

Therefore, your [tex]answer [/tex] is:  [tex] \frac{-165}{7} [/tex] [tex]aka[/tex] [tex] 23\frac{4}{7} [/tex]

One side of the triangle is 8 in, and the other two sides are equal to a positive whole number of inches. What is the smallest possible perimeter of the triangle?

F. 9 in
G. 10 in
H. 11 in
J. 15 in
K. 17 in

Answers

In a triangle the sum of two sides is always greater than the third side.

If one side = 8 in and other two sides are equal to a positive whole number, then the smallest possible sum of the other two sides = 9 in ⇒
Smallest possible perimeter = 8 + 9 = 17 in

If the divisor is 40 what is the least three digit dividend that would give a reminder four

Answers

The "division algorithm" states that:

Dividend = Divisor × Quotient + Remainder, where R<D

for example:

115 = 7*16+3, tells us that we can fit 7 into 115 at most 16 times,


Back to our problem, the Dividend is a 3 digit number, say abc, the divisor is 40 and the remainder is 4, so we have:

Dividend = Divisor × Quotient + Remainder

abc = 40 × Quotient + 4

we can try some values for the Quotient, but it almost immediately clear that the smallest Quotient that will produce the smallest dividend is 3:

40*2+4=80+4=84 (not 3 digit)
40 * 3 + 4=120+4=124 (the smallest 3 digit dividend)

Write y less than 21

Answers

I'm assuming you want us to translate the phrase into a mathematical inequality. 

"y less than..." means the y variable is less than something. "... 12" Which is 12.

In mathematics we use the < symbol to indicate "less than"

So, y < 12 is the answer.

Answer:

21-y

Step-by-step explanation:

In mathematics the signs used for more than is + and for less than is -.

The question is asking us to write y less than 21 in mathematical statement form.

y less than 21 means 21-y,

Hence the mathematical statement for y less than 21 is 21-y.

Answers

a straight line is 180 degrees so we can find C by subtracting 140 from 180

180-140 = 40 degrees

all 3 inside angles need to equal 180 so now we have

180 = 40 + (2x) + (x+2)

180 =  40 +3x +2

180=42+3x

138=3x

x= 138/3 = 46


 check : 2x= 2*46 = 92

x+2 = 46+2 = 48

92 +48 +40 = 180

 so x = 46 degrees

Find the length of the missing side. If necessary, round to the nearest tenth. side A = 38 side b =b side  c = 34
A. 51
B. 36
C. 72
D. 17

Answers

A) 51, assuming this is a *right* triangle:

38^2+34^2 = 50.99^2, rounding 51!!

The length of the missing side = side B = 17 (D) or 51(A)

Further explanation

Triangles are flat fields bounded by 3 intersecting sides and 3 angles

This side can be the same length or different.

If at an angle there is an angle of 90 degrees, this triangle is said to be a right angle

There is a hypotenuse in this triangle which is the sum of the two sides

[tex]\large{\boxed{\bold{C^2=A^2+B^2}}[/tex]

where c = hypotenuse

a and b = side/leg

This formula is known as the Pythagorean theorem which states that:

the hypotenuse or the longest side in a right triangle equal to the sum of the squares of the other sides.

or

the sum of the squares of the length of the two sides equals the square of the length of the hypotenuse

While the angle formulas used are

sin a = opposite / hypotenuse cos a = adjacent / hypotenuse tan a = opposite / adjacent

From the problem it is known that side A = 38 ,side b = b, side c = 34

There are 2 possible solutions to this problem because the image does not exist:

1. side A as the hypotenuse side (the longest side) 2. side B as hypotenuse side

Possible Solution no 1

A² = C²+B²(A=hypetenuse)

B² = A²-C²

B² = 38² - 34²

B² = 288

B = √288

B = 16.97, round to the nearest tenth ⇒ 17 (answer D)

Possible Solution no 2

B² = A²+C²(B=hypotenuse)

B² = 38² + 34²

B² = 2600

B = √2600

B = 50.99, round to the nearest tenth ⇒ 51 (answer A)

Paul has grades of 63 and 81 on his first two tests. What must he score on his third test in order to have an average of at least 70

Answers

To get an average of at least a 70, Paul would have to get at least a 66 on his third test.
(60+81+s)/3≥70  multiply both sides by 3

60+81+s≥210  combine like terms on left side

141+s≥210  subtract 141 from both sides

s≥69

So Paul will have to score 69 or more on his next test in order to have an average of at least 70.

A pyramid and prism have the same base area and height. The prism's base area is 8 square units and its height is 16 units. What is the volume of the pyramid? The volume of the pyramid is __________ cubic units. Enter the number that correctly fills in the blank in the previous sentence.

Answers

Prism dimensions:
8 units² (base area)
16 units (height)

Because the dimensions are the same...

Pyramid dimensions:
8 units² (base area)
16 units (height)

The volume for a pyramid = 1/3 ba * h

Substitute and solve.

   1/3 8 * 16
= 1/3 (128)
= 42.66...

Therefore the volume is approximately 42.67cm³

The volume of the pyramid with a base area of 8 square units and a height of 16 units is 42.67 cubic units.

The volume of a pyramid is calculated as one-third of the base area times the height. The base area of the given pyramid is 8 square units and the height is 16 units. Using the formula for volume V =  rac{1}{3}Ah, where A is the base area and h is the height, the volume of the pyramid can be found as follows:

V =  rac{1}{3}  imes 8  imes 16

V =  rac{1}{3}  imes 128

V = 42.67 cubic units (rounded to two decimal places).

Therefore, the volume of the pyramid is 42.67 cubic units.

Since we are given the lengths of 2 sides with the angle in between, therefore by cosine law we can only construct 1 triangle from this. By stating the angle in between, this constricts the possible number of triangles that can be formed into 1.

a = c + 2/b

Answers

The only one that's equivalent is The 3rd one. ab=c+2

Answer:

Option C.

Step-by-step explanation:

The given expression is ab - 2 = c

Option a : a = [tex]\frac{c}{b}[/tex] - 2

                 ab = c - 2b

                Not equivalent to the original expression.

Option b : b = c + [tex]\frac{2}{a}[/tex]

                 ab = ac + 2 ⇒  [tex](\frac{ab-2}{a})[/tex] = c

                Not equivalent

Option c  : ab = c + 2

                  ab - 2 = c

               Equivalent to original expression

Option d : a - [tex]\frac{c}{2}[/tex] = b

                 2a - c = 2b

                Not equivalent

Option e : b - [tex]\frac{2}{c}[/tex] = a

                 bc - 2 = ac ⇒ c (b-a) = 2 ⇒ c = [tex]\frac{2}{b-a}[/tex]

                 Not equivalent

Option f : a = c + [tex]\frac{2}{b}[/tex]

x=6 that is the number of vanilla wafers.

If you need further help, please let me know.....



Answer with explanation:Let x denotes the number of packets of vanilla wafers.and y denotes the number of packets of chocolate wafers.

Vanilla wafers cost $4 per packet

and chocolate wafers for $1 per packet

They spent a total of $45 .

This means that the equation that can be formed using this information is:

                   4x+y=45

and they buy a total of 27 packets of wafers.

i.e.   the equation formed with the help of this information is:

              x+y=27

PART A:

The system of equations that can be solved to find the number of packets of vanilla wafers and the number of packets of chocolate wafers that Josh and his friends bought at the carnival is:

                 4x+y=45-------------------(1)

and             x+y=27----------------(2)

PART B:

We will use the method of substitution because with the help of this method we could easily substitute the value of one variable in terms of the other variable and obtain the answer.

Using equation (2) we have:

   y=27-x-------------------(3)

On putting this value of y in equation (1) we have:

4x+27-x=45

i.e.

4x-x+27=45

i.e.

3x+27=45

i.e.

3x=45-27

i.e.

3x=18

i.e.

x=6

and on putting the value of x in equation (3) we have:

y=27-6

i.e.   y=21

Hence, number of vanilla wafers purchased = 6

and number of chocolates wafers purchased = 21
