Quinn is playing in a trivia competition. He earns 50 points for each correct response, . He loses 25 points for each wrong response, . Which expression represents Quinn's total points in the trivia competition? A

Answer:

C. (-3,6)

Step-by-step explanation:

Take 10x + 7y = 12 as first equation and 8x + 7y = 18 as second equation.

Subtracting both equations, you will get

10x + 7y - 8x - 7y = 12 - 18

2x = -6

x = -3

Substitute value of 'x' in any of the given equation :-

10x + 7y = 12

10 * -3 + 7y = 12

7y = 12 + 30

y = 42/7

y = 6

Answer:

C) (−3, 6)

Step-by-step explanation:

10x + 7y = 12 ___ (−3, 6)

10×(-3) + 7×6 = -30 + 42 = 42 - 30 = 12

8x + 7y = 18 ___ (−3, 6)

8×(-3) + 7×6 = -24 + 42 = 42 - 24 = 18

Answer:

x=-12

Step-by-step explanation:

Answer:

x = -12

Step-by-step explanation:

Combine like terms and solve for x

The number is 12.

A number, a variable, or a mix of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation. Word illustration: The product of 8 and 3. Word illustration: The product of 8 and 3 is 11

Given

let number be x.

3x-24 = x

3x-x = 24

2x=24

x = 12

Answer:

a)ΔFHA is similar to ΔZIA by hypotenuse side test.

reason:- angle H and angle I are of 90 degrees.

b) FH/ ZI = HA/ IA = FA/ ZA

angle F = angle Z, angle H = angle I , angle angle A = angle A

The scale factor is 3/2......( HA/IA = 12/8 = 3/2)

c) IZ = 3.3 ....( FH/ IZ = 3/2, 5/ IZ = 3/2, IZ = 10/3 = 3.33)

Answer:

Slope: 2/3

Step-by-step explanation:

A slope is rise over run. You first have to get two perfect points, which I got (1,2) and (4,4). The rise is how much does it goes up and the run it's how much it goes to the side. Since the line it's going up, it is positive. The rise is 2 and the run is 3.

Answer:

Slope: -3

Equation: [tex]y=-3x-5[/tex]

Step-by-step explanation:

As x increases by 1, your y decreases by 3, making the rise over run [tex]-3/1=-3[/tex]. That becomes the m in your y=mx+b equation, and since you have the y intercept, you can just plug and chug.

If I helped, a brainliest answer would be greatly appreciated!

Answer:

Slope = -3

m = -3 / 1 = -3

25/5

Step-by-step explanation:

first make the coefficient of x alone... So that you should take the 4 out... then you get 4times x squared + 5x then you should didvide the x term by 2(always) and then you get 5/2...So then the third term or the constant is tye square of that..

8.66 x 3.94 inches

Step-by-step explanation:

Answer:

1/8

Step-by-step explanation:

2⁻³ = 1 / 2³ = 1 / (2*2*2) = 1/8

so the minus sign in the exponent means you can put that factor in the denominator without the minus sign.

Orange per pound= $4.86

Step-by-step explanation:

Giving the following information:

Decrease rate= 20%

Price this week= $3.89 per pound

To calculate the price of oranges last week, we need to use the following formula:

Orange per pound= price this week / (1 - decrease rate)

Orange per pound= 3.89 / (1 - 0.8)

Orange per pound= $4.86

Answer:

so a=36, b=3, c=5, d=540

Answer:

fraction strips would just be;

1 box split into 12 parts because 12 is the common denominator, and 1/4 is equal to 3/12, so you would shade in 3 of the parts, and then 1/6 = 2/12, so you would shade in 2 parts. In the end, you should have a box (or rectangle) with 12 parts, and only 5 of those parts should be shaded in.

The equation would be as follows:

1/4+1/6 = 3/12+2/12 = 5/12

Hope this helped!! :)

Step-by-step explanation:

Answer:

The radius of the sphere is approximately 62.71 cm

Step-by-step explanation:

The question relates to the definition of a sphere

The given parameters are;

The distance between the sharp parallel blades through which the sphere is rolled = 77 centimeters

The radii of the circular faces left by cutting the sphere with the blade = 39 cm  and 60 cm

From the triangles formed by the cross-section of the sphere, we have;

AB ║ DE Given

∠A ≅ ∠E, ∠D ≅ ∠B Alternate angles

∠C ≅ ∠C by reflective  property

∴ ΔABC ~ ΔDCE by Angle-Angle similarity theorem

CF/CG = AB/DE = 78/120 = 13/20

CF = CG × 13/20

CF + CG = 77

∴ CG × 13/20 + CG = 77

33·CG/20 = 77

∴ CG = 140/3

CF = 13/20 × CG = 13/20 × 140/3 = 91/3

CF = 91/3

The diameter of the sphere AE = AC + EC

By Pythagoras's theorem

AC = √(FA² + CF²) = √(39² + (91/3)²) = 13·√(130)/3

EC = √(CG² + GD²) = √((140/3)² + 60²) = 20·√(130)/3

∴ AE = AC + EC = 13·√(130)/3 + 20·√(130)/3 = 11·√(130)

The diameter, 'D', of the sphere, AE = 11·√(130)

The radius of the sphere = D/2 = 11·√(130)/2 ≈ 62.71 cm

Answer: 110 Inches

Step-by-step explanation:

8x4 x 3 = 96

4 x 3.5 x .5 x 2 = 14

96 + 14 = 110

Answer:

Total=110 in²

Step-by-step explanation:

Basically just do all of the shapes individually so the triangles would equal 7 each b/c 4x3.5 divided by 2 so those would be 14 and the rectangles eahc equal 32 so multiply that times 3 and u get 96 then add the two triangles (7 each) which gets u 110 in²

Step-by-step explanation:

Answer:

Jerry's weight is 36kg and tom's weight is 66kg

Step-by-step explanation:

According to the given condition:

Let,tom's weight =x

Jerry's weight=y

So,

X=2y-6 ---(1)

X+y=102-----(2)

Put value of x from eq 1 in 2

2y-6+y=102

3y-6=102

3y=102+6

3y=108

Y=108/3=36

Jerry's weight is 36.

Put value of y in eq 1

X= 2(36) -6

X=72-6

X=66

So, Tom's weight is 66kg
