Find the value of X.
to
67°
56°

Answers

Answer 1

Answer:

x = 57

Step-by-step explanation:

180 degrees in a triangle

67 + 56 = 57

Answer 2

Answer: x = 57

==================================================

Explanation:

The three angles of any triangle always add to 180

x+67+56 = 180

x+123 = 180

x+123-123 = 180-123 .... subtract 123 from both sides

x = 57

The missing angle is 57 degrees

-------------

Check:

x+67+56 = 57+67+56 = 180

Answer is confirmed.

Did I mess it up? Can I get checked?

Answers

Answer:

You are correct!

Step-by-step explanation:

Hi!

You are right! If y is in the same spot as 58 degrees, then y is 58 degrees as well! Same goes for x. If z is 122 degrees, then x must be 122 degrees! Great job figuring this one out!

the system ax-by=-16 and ax+2y=20 has one solution at the point (3,4). Find a and b. (a=4,b=7)

Answers

Answer:

Step-by-step explanation:

substitute (3,4) to equation: ax+2y=20

3a+8=20

a=4

Then, 4x-by=-16

substitute (3,4) to solve b,

4*3-b(4)=-16

b=7

Why does the government charge high taxes on gasoline?

Answers

Answer:

Every time you top off your vehicle at the pump, you're paying federal and state gas taxes that are included in the price of every gallon of gasoline. The federal tax, at 18.4 cents per gallon, is meant to help the federal government pay to build and fix things like highways and bridges.

Step-by-step explanation:

Mark me brainliest

Answer: These taxes are meant to do two things — raise money to pay for infrastructure and reflect some of the environmental costs of driving. Unlike most taxes, gas taxes are charged as a flat charge per liter, rather than as a percentage of the pump price.

Find the gradient of the straight line joining A(-4, -1) to B(4, 2)

Answers

Answer:

The slope of the line is [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

Given parameters:

A(-4, -1) to B(4, 2)

Unknown:

The slope of the line joining the two points

Solution:

To find the slope of the line; we use the expression below:

Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} -x_{1} }[/tex]

x₁ = -4

y₁ = -1

x₂ = 4

y₂ = 2

Input the parameters and solve;

Slope = [tex]\frac{2 -(-1)}{4-(-4)}[/tex]

Slope = [tex]\frac{3}{8}[/tex]

The slope of the line is [tex]\frac{3}{8}[/tex]

At 2:00 AM in Alaska, the temperature was -1°F. The temperature dropped 3 degrees each hour after that. What
was the temperature 3 hours later?
A -8°F
B
-23 F
C -4°F
D-124 F

Answers

Answer:

-10* F

Step-by-step explanation:

What confuses me is that the answers you have provided aren't correct, when I made a number line starting at 0 and ending at -23* F and I had counted three degrees for each hour I got -10* F.

2am 3am 4am 5am

0 -1 -2 -3 -4 -5 -6 -7 -8 -9 -10 -11 -12 -13 -14 -15 -16 -17 -18 -19 -20 -21 -22 -23

2am is at -1* F, 3am is at -4* F, 4am is at -7* F, and 5am is at -10* F.

This is over the course of three hours after 2am so unless I got this wrong you might want to ask your teacher.

in a salad with vegetables containing 50 calories dressing is added at 100 calories per ounce. The total number of calories can be represented by the equation f(x) = 100x +50. What is the reasonable range for the situation?

Answers

Answer:

Step-by-step explanation:

To get the reasonable range of the situation, we will find the minimum value and maximum value of the calories that can be dressed.

The minimum occur at when x = 0

f(0) = 100(0) +50.

f(0) = 50

Hence the minimum value of the calorie is 50.

The maximum value occur at f'(x)

f'(x) = 100

Hence the maximum value of the calorie is 100

Hence, the reasonable range for the situation is 50 ≤ x ≤ 100

what is the equation of a like that goes through the point 5,-2 and has a slope of. 6/5

Answers

Answer:

y= 6/5x -8

Step-by-step explanation:

The slope-intercept form (basically the form for the equation of a line)

y=mx+b

m is the slope

x is the value you want to plug in, or the x term in a point (x, y)

we know so far,

y=6/5x + b

so to find the missing value let's plug in the x & y value from (5, -2) and use the given slope

-2 = 6/5(5) + b

6 / 5 x 5/1 or 6/5 times 5 is 30/5 or 6

-2 = 6 + b

subtract 6 from each side to isolate the b value or y-intercept ( the point on the graph that is on the y-axis)

-8 = b
