Hey there!

If you do this, I would suggest saying "strongly agree"

This means that you can solve them using strategies that make it easier.

Have a super awesome day! :)

Answer:

The answer is 28

Step-by-step explanation:

Since the total measurements of triangle corners are equal to 180

Then

[tex]2x + 3x - 10 + 50 = 180 \\ 5x - 40 = 180 \\ 5x = 140 \\ x = 28[/tex]

Answer:

  x = 10

Step-by-step explanation:

You can compare parts of each expression to see that x in the left-side expression is replaced by 10 in the right-side expression.

  x = 10

__

If you'd rather, you can work your way down to the same conclusion by undoing the operations that have been done to x.

  (6x -1)° = (6(10) -1)° . . . . . . given

  6x -1 = 6(10) -1 . . . . . . . . . divide both sides by °

  6x = 6(10) . . . . . . . . . . . .  add 1 to both sides

  x = 10 . . . . . . . . . . . . . . . . divide both sides by 6

Answer:

$7.60

Step-by-step explanation:

10 decrease 20% =

10 × (1 - 20%) = 10 × (1 - 0.2) = 8

8 decrease 5% =

8 × (1 - 5%) = 8 × (1 - 0.05) = 7.6

Answer:

y = 30

z = 115

Step-by-step explanation:

z° + 65° = 180°

(Exterior Angles on the same side of transversal)

z° = 180° - 65°

z° = 115°

z = 115

(5y - 85)° + z° = 180°

(Linear pair angles)

(5y - 85)° + 115° = 180°

(5y - 85)° = 180° - 115°

(5y - 85)° = 65°

5y - 85 = 65

5y = 65 + 85

5y = 150

y = 150/5

y = 30

Answer:

Step-by-step explanation:

(x - y)² = x² - 2xy + y²

x = b  ; y = 3

(b - 3)² = b² - 2 *b * 3 + 3²

          = b² - 6b + 9

Answer:

14

Step-by-step explanation:

this is a 30-60-90° Δ and the sides, respectively, have the ratio of 1 : [tex]\sqrt{3}[/tex] : 2

we can set up a proportion and cross-multiply based on that ratio:

w / 7[tex]\sqrt{3}[/tex] = 2 / [tex]\sqrt{3}[/tex]

[tex]\sqrt{3}[/tex]w = 14[tex]\sqrt{3}[/tex]

w = 14

Answer:

5

Step-by-step explanation:

The equation [tex]y=5x+10[/tex] is given in slope-intercept form. Slope-intercept form is a way of writing the equation of a line in the format [tex]y=mx+b[/tex], such that the coefficient of the parameter (x) is the slope, and constant (b) is the y-intercept. What that essentially means is,

[tex]y = mx + b\\\\m=slope\\b = y-intercept.[/tex]

The slope of a line is its rate of change, and the y-intercept is where the graph of the line intersects the y-axis. One can apply this knowledge here by saying that, the equation [tex]y=5x+10[/tex] is given in the slope-intercept form, and the coefficient ([tex]m[/tex]) equals ([tex]5[/tex]), therefore the slope is ([tex]5[/tex]).

Answer:

rises to the left and rises to the right

Step-by-step explanation:

The end behavior of the graph of f(x) = 3x⁶ + 30x⁵ + 75x⁴ is that it as x → -∞, y → ∞ and as x → -∞, y→ ∞.

A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

The degree of the polynomial function is 6, which is even, and the leading coefficient is positive, so the end behavior of the graph is as follows:

As x approaches negative infinity, both the x⁶ and x⁵ terms become very large positive numbers, and so the value of the function f(x) approaches positive infinity.

As x approaches positive infinity, both the x⁶ and x⁵ terms become very large positive numbers, and so the value of the function f(x) also approaches positive infinity.

Therefore, the end behavior of the graph of f(x) is that it as x → -∞, y → ∞ and as x → -∞, y→ ∞.

Answer:

temp after 7 minutes is 135°

temp after 't' minutes:  y = 65 + 10t

Step-by-step explanation:

Answer:

1) 135°

2) 65° + 10t°

Step-by-step explanation:

What is the temperature of the oven 7 minutes after being turned on?

65° (initial temperature) + 10° (temperature increase per minute) × 7 (amount of minutes)

10 × 7 = 70

65° + 70° = 135°

What is the temperature of the oven t minutes after being turned on?

65° (initial temperature) + 10° (temperature increase per minute) × t (amount of minutes)

10 × t = 10t

65° + 10t°

Number of bacteria after 30 minutes:

Correct choice is C

Answer:

after 10 minute total bacteria=2.5×3.3=8.25 millions

in 1 minute total bacteria=2.5×3.3/10 =0.825millions

in 30 minute total bacteria=30×2.5×3.3/10 millions=24.75million is your answer.but i did not get any match.

Answer:

80°

Step-by-step explanation:

Here the missing angle is x

So,

x + 100° = 180° [linear pair]

=> x = 180° - 100°

=> x = 80° (Ans)
