Answer:

Step-by-step explanation:

In direct proportion, as the first variable increases (decreases), the second variable also increases (decreases). In mathematical statements, it can be expressed as y = kx. This reads as “y varies directly as x” or “y is directly proportional as x” where k is constant in the equation

In this equation, y and x are the two directly proportional quantities and k is a proportionality constant that tells you exactly how they are related (like 10 cents/piece above). On a graph, a direct proportion will look like a straight line and the slope of the line will be equal to the constant k

What is the value of x in the figure?<br> Enter your answer in the box.<br><br> x =

Blababa [14]

Answer:

The value of x in the given figure is, $34^{\circ}$

Step-by-step explanation:

Complementary angle states that the two angles sum up to 90 degree.

From the given figure

$x^{\circ}$ and $56^{\circ}$ are complementary angles.

by definition of complementary angles;

$x^{\circ} +56^{\circ} = 90^{\circ}$

Subtract $56^{\circ}$ from both sides we get;

$x^{\circ} = 90^{\circ} -56^{\circ}$

Simplify:

$x = 34^{\circ}$

therefore, the value of x in the given figure is, $34^{\circ}$

First to answer correctly gets brainliest

Readme [11.4K]

Answer:

240 $\leq$ 12.5p + 65

14 $\leq\\$ p

Step-by-step explanation:

I'll explain the equation in different parts

12.5p - Since the number of times he visits is unknown, it has to be a variable. With each visit, however, he earns 12.5 points.

65 - This is a set value that remains constant

240 $\leq\\$ - Since he needs AT LEAST 240 points, he needs 240 points or more to get his free ticket

As for solving the equation just use properties of equality

240 $\leq$ 12.5p + 65

175 $\leq$ 12.5p

14 $\leq\\$ p

One number added to three times another number is 24. Five times the first number added to three times the other number is 36. F

Lera25 [3.4K]

Okay, so the equations would be:
x + 3y = 24
3y + 5x = 36

Imma use Substitution to solve this:
x = -3y + 24

3y + 5(-3y + 24) = 36
3y - 15y + 120 = 36
-12y + 120 = 36
-12y = -84
y = 7

x = -3(7) + 24
x = -21 + 24
x = 3

So the first number (x) would be 3 and the second number (y) would be 7.
