Answer:

Jessica will have saved $175, and Ron will have saved $165.

Step-by-step explanation:

Jessica starts out with $50. She adds $25 each week, and it's asking how much money she would have in 5 weeks. So, you multiply $25 by 5 to get $125. Then, you add $50 to that to get $175. Same thing for Ron. Multiply $25 by 5 to get $125, but this time add $40 to it to get $165.

Answer:

Jessica- $175

Ron- $165

Step-by-step explanation:

Jessica starts with $50 so put that aside and then it says that she adds $25 EVERY WEEK so how much is she going to have in 5 weeks? 5 x $25 is $125 and now add the $50 which will equal $175

In Ron is the same thing but rather than adding $50 add $40 and it will equal $165

Answer:

x = 6.5

Step-by-step explanation:

1.5x - 2.3x + 4 = 1.2

1.5x - 2.3x = -1.2 - 4

-0.8x = - 1.2 - 4

-0.8x = -5.2

divide both sides of the equation by -0.8

x = 6.5   :)

Answer:

n=1+√47 or n=1−√47

Step-by-step explanation:

Let's solve your equation step-by-step.

n2−2n−48=−2

Step 1: Subtract -2 from both sides.

n2−2n−48−(−2)=−2−(−2)

n2−2n−46=0

For this equation: a=1, b=-2, c=-46

1n2+−2n+−46=0

Step 2: Use quadratic formula with a=1, b=-2, c=-46.

n=

−b±√b2−4ac

n=

Answer:

Infinitely many solution

Step-by-step explanation:

Simplify

2x - 4 = 2x - 4

Lets see:

if we put 1:

2 - 4 = 2 - 4

-2 = -2

Now lets try another number : 2

4 - 4 = 4 - 4

0 = 0

So we can say that there is more than one solution

this cancels out single solution and no solution

There are infinitely many solutions to the given algebraic expression 2x - 4 = 2(x - 2).

The algebraic expression is an expression that is composed of variables and their arithmetic operations.

From the given parameters

Open brackets

Since we are having the same algebraic expression on both sides;

Then, we won't be able to get exactly one solution but an infinite number of solutions.

This is because any number that is being substituted for the value of x will always give a different solution.

Answer:

x = 12

Step-by-step explanation:

The exterior angles of any polygon always add up to 360, so:

[tex]5x+4+4x+9+7x+4+9x-6+4x+1=360\\29x+12=360\\29x = 348\\x = 12[/tex]

Answer:

The base = 24 in

The height = 16 in

Steps:

x(x-8)/2 = 192

(x²-8x)/2 = 192

x²-8x = 192 × 2

x²-8x = 384

x²-8x-384 = 0

by using the quadratic formula, the roots are: (24, -16)

hence

x = 24

The base = 24 in

The height = 16 in

Answer:

28 mm

Step-by-step explanation:

All sides of a rhombus are equal in length and there are 4 sides so do 7 * 4 = 28mm.

Answer:

Perimeter of Rhombus: 28mm

Step-by-step explanation:

If one side of a Rhombus is 7mm, then its perimeter is 28 because all sides of a Rhombus is equal.

Answer:

i have no clue

Step-by-step explanation:

First approach :

The above series can be seen as

1600 , (1600–400) 1200, (1200–300) 900 .

So we see that the values are getting decreased by 400,300 respectively.

Hence the next term in the sequence will be 900–200 = 700.

Other approach could be :

A geometric progression with ratio as 3/4.

1600*(3/4) = 1200

1200*(3/4) = 900

900*(3/4) = 675

Taking the above two approaches in mind,the two possible answers could be 700 or 675

Um- here ya go

The 20th term of the sequence.

1600, 1200, 900, ..., is 6.76.

A unique kind of sequence called a geometric sequence has a constant ratio between every two succeeding terms. This ratio is regarded as one of the geometric sequence's common ratios.

aₙ=a₁(r)ⁿ⁻¹

Given:

A geometric sequence,

1600, 1200, 900, ...

To find the common ratio:

take the ratio of successive terms

r = The value of the second term / the value of the first term

r = 1200/1600 = 0.75.

The explicit formula of a geometric sequence is,

aₙ=a₁(r)ⁿ⁻¹

aₙ= 1600(0.75)ⁿ⁻¹

a₂₀ = 1600(0.75)¹⁹

a₂₀ = 6.76

Therefore, the 20th term is 6.76.
