-3x+7y=5x+2y Please HELP Complete the missing value in the solution to the equation.
(-5,_)

Answers

Answer:

(-5, -8); the missing value is -8

Step-by-step explanation:

First, you need to simplify the given equation to isolate y

1: -3x + 7y = 5x + 2y (Given)

2: 7y = 8x + 2y (Add 3x to both sides)

3: 5y = 8x (Subtract 2y from both sides)

4: y = 8/5x (Divide both sides by 5)

Now, you can use this to solve for the missing y in value set (-5, y)

where y = 8/5x and x = -5,

y = 8/5(-5)

y = -8

so, the missing value is -8

help with this bounds question please

Answers

Answer: 6.68km/litre

Step-by-step explanation:

Distance(d) = 187km ( to 3 significant figures)

Petrol(p) = 28litres ( to 2 significant figures)

A number, x, rounded to 1 significant figure is 200

Write down the error interval for x

Calculating the lower and upper bound for both 'd' and 'p'

Upper bound 'd' = 187.5km

Lower bound 'd' = 186.5km

Upper bound 'p' = 28.5km

Lower bound 'p' = 27.5km

Therefore,

Petrol consumption (C) = d/p

Upper C = 187.5 / 28.5 = 6.57894

Lower C = 186.5 / 27.5 = 6.781818

Accuracy answer for C = (6.57894 + 6.781818) / 2 = 6.680379

= 6.68km/ litre ( to 3 significant figures)

To achieve a reasonable level of accuracy, the upper and lower bounds of P and D was used to calculate C, which was then averaged.

Using 3 significant figures ensure that we capture the C better, instead of early rounding.

6.A circle has a diameter of 11 inches. What is the circumference of the circle using ≈ 3.14? = . Single choice.

Answers

Answer:

Circumference of the circle = 34.54 inches

Step-by-step explanation:

Explanation

Given that diameter of the circle

                                    d = 11inches

The radius of the circle    

                                [tex]r = \frac{d}{2} = \frac{11}{2} = 5.5[/tex]

Circumference of the circle

                              = 2πr

                             = 2×3.14×5.5

                           = 34.54

Final answer:-

Circumference of the circle = 34.54 inches

A.) 18.7 units
B.) 10.5 units
C.) 9 units
D.) 13 units

Answers

Answer:

B.) 10.5

Step-by-step explanation:

Use ratios, but be careful.

AE/AD = AB/AC

14/18 = x/(x+3).

14x+42 = 18x

42 = 4x

x = 10.5

The value of x in the given figure is 10.5 so, option B.) 10.5 units is correct.

What is the ratio of two quantities?

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b

or

[tex]\dfrac{a}{b}[/tex]

Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.

Using ratios;

AE/AD = AB/AC

14/18 = x/(x+3).

14x+42 = 18x

42 = 4x

x = 10.5

Thus, option B.) 10.5 units is correct.

PLZ HELP IM BEGGING

Answers

Answer:

-x+y= -14 (get this equation to where you can easily plug it in for a variable)

y= x -14

5x +6y =26 (plug the value above in for y and then solve)

5x + 6 (x-14) = 26 (use the distributive property)

5x +6x - 84 = 26 (combine like terms on the left side)

11x - 84 =26 (add 84 to both sides)

11x = 110 (divide both sides by 11 to isolate the x-variable)

x= 10 (this is the value for x. plug it into the easier equation and solve)

-(10) +y = -14

y= -4

(10, -4) (this is the solution for the system of equations)
