Answer:

I believe your answers would be 80-(-5) and 80+5

Step-by-step explanation:

Answer:

Choice 1 and 2

Step-by-step explanation:

If it was marked wrong his actual score should be 85.

80 - (-5)     When you subtract a negative it turns positive. So:

80 + 5

85

Also

80 + 5 = 85

Answer:

Y= -4/3x-1

Step-by-step explanation:

The distance from our y values is -16

The distance from our x values is 12

We have -16/12 which we reduce to -4/3

Rise/Run=Y/X

Use can use the rise over Run strategy to eventually find your y intercept which is -1.

Answer:

Y= -4/3x-1

Use the linear equation to solve problems like this.

Answer:

The one I usually use is divide both sides by 4

Step-by-step explanation:

Well, we know that it costs $60 plus 5 per month for Alpha Fitness Club.

We also know that it costs $20 plus 10 per month for Omega Fitness Club.

In order to find out which one would cost the most, we must add the additional costs to the original join cost.

(NEVER add the join cost, just do the join cost at the beginning or else the clubs will never become the same cost.)

Club      M1  M2  M3  M4  M5  M6  M7  M8  M9

Alpha:   60   65  70   75   80   85   90  95  100

Omega:20   30  40   50   60   70   80  90  100

If you look above, you realize that there is a time when they both cost the same.

Summary sentence:

After 9 months, the cost to belong to either fitness club would be $100.

Answer:

4 1/4 kg

Step-by-step explanation:

2 3/4 + 1 1/2

convert to have common denominators

2 3/4 + 1 2/4

convert to improper fractions (whole number × denominator + numerator / denominator)

11/4 + 6/4

add numerators and keep same denominator

17/4

convert to mixed number

17 goes into the denominator 4 times with 1 left over so:

4 1/4

Answer:11/4 + 3/2

LCM of denominators = 4

11/4 x 1 = 11/4 and 3/2 x 2 = 6/4

So, 11/4 + 6/4 = 17/4 = 4 1/4

Answer:

5(10) + 5(7) = 85

Step-by-step explanation:

Let the length of the base of this isosceles triangle be = x

One of its equal sides = 3x

Another one of its equal sides = 3x

Their perimeter = x + 3x + 3x = 21 cm

To find the value of each side let us first solve this equation .

= x + 3x + 3x = 21 cm

= 7x = 21 cm

= x = 21 ÷ 7 ( transposing ×7 from LHS to RHS changes ×7 to ÷7 )

= x = 3

Then length of base = 3 cm

Length of one equal side = 3 × 3 = 9 cm

Length of another equal side = 3 × 3 = 9 cm

Therefore , the the three sides of this triangle = 3 cm , 9 cm and 9cm .

Answer:

2x^2 + 17x + 21

Step-by-step explanation:

Set up binomial multiplication square

2x(x) + 2x(7) + 3(x) + 3(7)

multiply items together to get

2x^2 + 3x + 14x + 21

Add like terms together to get your final answer

2x^2 + 17x + 21

(I dont have exponent buttons so the ^2 means squared )'

Answer:

x=2

Step-by-step explanation:

2x+x- 5 =0

[tex]x° + 135° = 180° \: ( \: linear \: pair \: )[/tex]

[tex]x = 180 - 135[/tex]

[tex]x = 45°[/tex]

Therefore , the value of x = 45° .

Step-by-step explanation:

Expand: 9 - 15 +12x

Simplify: -6 + 12x

-6 (1 - 2x)

The solution of the given expression 9-3(5-4x) is -6 (1 - 2x).

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 9-3(5-4x). The expression will be simplified as:-

E = 9 - 15 +12x

E = -6 + 12x

E = -6 (1 - 2x)

Therefore, the solution of the given expression 9-3(5-4x) is -6 (1 - 2x).

Increase in the length of one side = 3.8 ft

Step-by-step explanation:

Yossi has garage whose area is 280 ft²

After rebuilt their is increment in area by 50%

New Area = 280 × 150% = 420 ft²

Also we know that Area of Square = (Length) × (Length)

⇒ Length of Newly built garage = √420 = 20.5 ft

and Length of Originally garage = √280 = 16.7 ft

⇒ Increase in the length of one side = 20.5 - 16.7 = 3.8 ft

Answer:

[tex]\frac{8}{9}[/tex]

Step-by-step explanation:

We have to create 2 fractions with the repeating number placed after the decimal point.

let x = 0.88.... → (1) ( multiply both sides by 10 )

10x = 8.88.... → (2)

Subtract (1) from (2), eliminating the repeating decimal

9x = 8 ( divide both sides by 9 )

x = [tex]\frac{8}{9}[/tex]

Thus 0.888..... = [tex]\frac{8}{9}[/tex]
