Step-by-step explanation:

-3x>29-32

-3x>-3

Answer:

Hope this helps :)

Step-by-step explanation:

32>3x+29

Switch sides

3x+29<32

Subtract

3x+29-29<32-29

Simplify

3x<3

Divide

3x/3<3/3

Simplify

x<1

\( \tt \dashrightarrow 8 \times 4 = ( \triangle \times 7) - (\triangle \times 3)\)

\( \tt \dashrightarrow 32 = 7 \triangle - 3\triangle \)

\( \tt \dashrightarrow 32 = 4 \triangle \)

\(\tt \dashrightarrow \cancel\dfrac{32}{4} = \triangle \)

\(\tt \dashrightarrow 8 = \triangle \)

\(\tt \dashrightarrow \triangle = 8 \)

Hence, value of ∆ is 8.

Step-by-step explanation:

We need to find the angle (rounded to the nearest whole degree) of a circle that would represent the percent of students taking mathematics.

Since a complete turn around the circle has 360º, we have the following proportion:

Number of students Angle

734 360º

442 x

Then, cross multiplying the above values, we obtain:

Answer: 217º

Answer:

217°

Step-by-step explanation:

The fraction of students taking math is   442/734

 we need this same fraction of the 360 degrees in a circle

442/734 * 360 = 217°

Step-by-step explanation:

I=$425*2*3/100

I=25.5

The length of GH is 15.

GH = IG

GH = 5x - 10

IG = 3x

5x - 10 = 3x

5x - 3x = 10

2x = 10

x = 10/2 = 5

GH = 5x - 10

= 5 * 5 - 10 = 25 - 10

GH = 15

<ABD = < DBC

<ABD = 10y°

<DBC = (8y + 4)°

10y° = (8y + 4)°

10y = 8y + 4

10y - 8y = 4

2y = 4

y = 4/2 = 2

The value of y is 2

<DBE = <DBC + <CBE

<DBC = 10y°

<CBE = <DBC = 10y°

y = 2

<DBC = <CBE = 10y° = 10*2° = 20°

<DBE = 20° + 20° = 40°

Answer: $972.7972 or $973

To find the amount of money Mary should deposit each quarter, we will use the following equation:

Where:

P = deposit made n times

i = is the interest rate r compounded m times per year

Since Mary wants to invest every three months, that would be 4 times per year and have the interest rate of 2% = 0.02,

The amount she wants to save is A = $12000, and she will invest 12 times, n = 12.

Substituting these to the formula and we will have:

This means that Mary has to pay approximately $972.7972 or $973 each quarter.

Step-by-step explanation:

do a square with 10 sides and color in 5 parts

Given:

The equation is:

\(efg-h=i\)

To find:

The value of f.

Solution:

We have,

\(efg-h=i\)

We need to isolate f to find the value of f.

Adding h on both sides, we get

\(efg-h+h=i+h\)

\(efg=i+h\)

Dividing both sides by \(eg\), we get

\(\dfrac{efg}{eg}=\dfrac{i+h}{eg}\)

\(f=\dfrac{i+h}{eg}\)

Therefore, the value of f is \(f=\dfrac{i+h}{eg}\).

Step-by-step explanation:

Answer:

x = -5/4

y = 1

Step-by-step explanation:

4x - 5y = -5

To find the x-intercept/zero, substitute y = 0

4x -5 x 0 = -5

4x -5 x 0 = -5

Any expression multiplied by 0 equals 0

4x - 0 = -5

Removing 0 doesn't change the value, so remove it from the expression

4x = -5

4x = -5

Divide both sides of the equation by 4

x = -5/4

4x - 5y = -5

To find the y-intercept, substitute x = 0

4 x 0 - 5y = -5

Solve the equation for y

y = 1

A triangle whose sides form a Pythagorean triple is called a Pythagorean triangle, and is necessarily a right triangle. The name is derived from the Pythagorean theorem , stating that every right triangle has side lengths satisfying the formula a2+ b2= c2; thus, Pythagorean triples describe the three integer side lengths of a right triangle.

\(\dfrac{15}{4} \div\dfrac{5}{8}\)

In order to divide two fractions, you will need to use the KCF method.

Keep

Change

Flip

This means that we will keep the first fraction, change the division to multiplication, and flip the second fraction(reciprocal).

\(\dfrac{15}{4} \times\dfrac{8}{5}\)

Multiply:

\(\dfrac{15}{4} \times\dfrac{8}{5}\)

\(\dfrac{15\times8}{4\times5}\)

\(=\dfrac{120}{20}\)

Simplify:

\(120\div20\)

\(=\fbox{6}\)

Answer: 6

Step-by-step explanation:

1. 15/4 divided by 5/8 = 120/20

15/4 / 5/8 = 15/4 times 8/5 = 15 time 8 over 4 time 5 = 120/20

=====================================================

Explanation:

x = number of two-pointers made

2x+1 = number of three-pointers made

This is because of the fact that she made one more than twice as many three-pointers than two-pointers.

In other words,

number of three pointers = 2*(number of two pointers) + 1

number of three pointers = 2x + 1

-------------------

If she made x two-pointers, then she gets 2x points from just those made shots.

If Nikki made 2x+1 three-pointers, then she gets 3(2x+1) = 6x+3 points from just the stuff beyond the arc.

In total, she earns (2x)+(6x+3) = 8x+3 points from both types of shots.

-------------------

Set this equal to the stated total 43 points and solve for x.

8x+3 = 43

8x = 43-3

8x = 40

x = 40/8

x = 5

Nikki made 5 two-pointers and 2x+1 = 2*5+1 = 11 three-pointers

--------------------

Check:

A = points from two-pointers only = 2*5 = 10 points

B = points from three-pointers only = 3*11 = 33 points

A+B = total points = 10+33 = 43 points

The answer has been confirmed.

The expression (-4)^2/7 can be written as seventh root 16

The √ symbol that is used to denote square root or nth roots. A radical expression is an expression containing a square root. Radicand is a number or expression inside the radical symbol. Radical equation is an equation containing radical expressions with variables in the radicands.

For example, x^2/3, 3 is the root while 2 is the power of x . therefore the x^2/3 can be written as cube root of x squared.

Similarly in (-4)^2/7 2 is the power of (-4), this means (-4)² = 16

7 is the root of (-4)²

Therefore (-4)^2/7 can be written in radical for seventh root 16.

Using substitution method of simultaneous linear equation the results are x = -1 and y = 3

What is simultaneous linear equation?

At first it is important to know about linear equation

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A one degree equation is known as linear equation.

Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.

Here,

Substitution method of simultaneous linear equation is used

y = -2x + 1

-9x - 2y =3

Putting the value of y in the second equation

-9x - 2(-2x + 1) = 3

-9x +4x -2 = 3

-5x = 3 + 2

-5x = 5

\(x = -\frac{5}{5}\\x = -1\)

Putting the value of x in the first equation,

\(y = -2 \times -1+1\\y = 3\)

Answer:

The answer is C) Obtuse and F) Isosceles

Answer: Down below

Step-by-step explanation:

Let x be the cost for the DVD's

Let y be the cost of the CD's

Equations :

2x + 2y = 18   OR   y = (18 - 2x)/2

3x + 2y = 22

Substitution :

3x + 2[(18 - 2)/2] = 22

3x + 2(16/2) = 22

3x + 2(8) = 22

3x + 16 = 22

3x = 22 - 16

3x = 6

x = 6/3

x = 2

that's just the cost of the DVD though. now to find the CD's cost

Cost of CD's :

y = (18 - 2x)/2

y = [18 - 2(2)]/2

y = (18 - 4)/2

y = 14/2

y = 7

therefore 1 CD costs 7 pounds and 1 DVD costs 2 pounds
