Find the value of x and y.
Answers
Answer:
x=25, y=19
Step-by-step explanation:
130+2x=180
x=25
54+2x+4y=180
y=19
Answer:
x = 25 , y = 19
Step-by-step explanation:
130° and 2x° are adjacent angles on a straight line and sum to 180° , so
130 + 2x = 180 ( subtract 130 from both sides )
2x = 50 ( divide both sides by 2 )
x = 25
--------------------------------------------------------------
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
130° is an exterior angle of the triangle , then
54 + 4y = 130 ( subtract 54 from both sides )
4y = 76 ( divide both sides by 4 )
y = 19

Use the point-slope formula to write an equation of the line that passes through (-5, -4) and (3, -1).
Write the answer in slope-intercept form (if possible).
Answers
Answer:
point slope form: y + 4 = 3/8 (x + 5) slope intercept: y = 3/8x - 17/8
Step-by-step explanation:
y2 - y1 / x2 - x1
-1 - (-4) / 3 - (-5)
slope = 3/8
y + 4 = 3/8 (x + 5)
y = 3/8x + b
-1 = 3/8(3) + b
-1 = 9/8 + b
-17/8
y = 3/8x - 17/8

if the gradient of a line is 2 and (7,2) is a point on the line, find it's equation
Answers
Answer:
y = 2x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c is the partial equation
To find c substitute (7, 2 ) into the partial equation
2 = 14 + c ⇒ c = 2 - 14 = - 12
y = 2x - 12 ← equation of line

Your cousin gave you $7.41 to buy a present. This amount covered 3/4 of the total cost. How much did the present cost?
Answers
Answer:
The answer is $5.55
Step-by-step explanation:
7.41 * 3/4= 5.5575
The present cost will be $9.88.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The amount to give cousin = $7.41
This amount covered 3/4 of the total cost.
Now,
Let the present cost = x
So, We can formulate;
⇒ 3/4 of x = $7.41
Solve for x as;
⇒ 3/4 × x = $7.41
⇒ x = $7.41 × 4 / 3
⇒ x = $9.88
Thus, The present cost will be $9.88.

Given two complimentary angles, n and (2n+3) find the value of n
Answers
Answer:
Sorry but
...
Step-by-step explanation:
Complementary Angles:
Two angles are called complementary angles, if their sum is one right angle i.e. 90°.
Each angle is called the complement of the other.
Example, 20° and 70° are complementary angles, because 20° + 70° = 90°.
Clearly, 20° is the complement of 70° and 70° is the complement of 20°.
Thus, the complement of angle 53° = 90° - 53° = 37°.
Answer:
(2n+3)+n=90°
2n+3+n=90°
3n+3=90°
3n=90-3
3n=87
n=29°
