In triangle ABC, Angle A is twice the size of angle B, angle C measures 20 degrees less than angle A, find the measurements of a,b, and c
I assume a, b, and c are the measures of the angles A, B, and C themselves. (If you meant lengths of the sides opposite these angles, this would be impossible.)
The interior angles to any triangle sum to 180° in measure, so
A + B + C = 180°
Now,
• A is twice the size of B, so A = 2B or B = A/2
• C measures 20° less than A, so C = A - 20°
Substitute these into the first equation and solve for A :
A + A/2 + (A - 20°) = 180°
5/2 A - 20° = 180°
5/2 A = 200°
A = 80°
Solve for B and C :
B = 80°/2
B = 40°
C = 80° - 20°
C = 60°

Answer:
Step-by-step explanation:
a = 12 cm ; b = 8 cm and h = 6 cm
a) Area of Trapezium = [tex]\dfrac{(a+b)*h}{2}[/tex] , where a and b are length of non parallel sides.
[tex]=\dfrac{(12+8)*6}{2}\\\\=\dfrac{20*6}{2}\\\\= 10 * 6\\\\= 60 \ cm^{2}[/tex]
b) x 0 1 2 3 4
y 7 4 1 -2 -5
3x + y = 7
y = -3x + 7
When x = 0 ; y = 0 + 7 = 7
When x = 1 ; y = -3*1 + 7 = -3 +7 = 4
When x = 2 ; y = (-3) *2 + 7 = -6+7 = 1
When x = 3 ; y = (-3)*3 +7 = -9 + 7 = -2
When x = 4 ; y = (-3) *4 + 7 = -12 + 7 = -5
c) Let the consecutive even number = (2x + 2) & (2x + 4)
9 *greater number - 7 *smaller number = 46
9*( 2x+ 4 ) - 7(2x + 2)= 46
9*2x + 9*4 - 7 *2x - 7*2 = 46
18x + 36 - 14x - 14 = 46
18x - 14x + 36 - 14 = 46
4x + 22 = 46
4x = 46 - 22
4x = 24
x = 24/4
x = 6
2x + 2 = 2*6 + 2 = 12 + 2 = 14
2x +4 = 2*6 + 4 = 12 + 4 = 16
The consecutive even numbers are 14 & 16
SALES Cars and trucks are the most popular vehicles. Last year, the number of
cars sold was 39,000 more than three times the number of trucks sold. There
were 216,000 cars sold last year. Write an equation that can be used
Answer:
39,000+3x=216,000
Step-by-step explanation:
brainliest please
The equation that can be used is 216,000 = 3T + 39,000 and the number of trucks sold last year is 59,000.
Given,
Number of cars sold last year = 216,000
The number of cars sold last year = 39,000 more than three times the number of trucks sold.
Let the number of trucks sold last year = T
Write the equation of the number of cars sold last year.
The number of cars sold last year = 39,000 more than three times the number of trucks sold.
216,000 = 3T + 39,000
Find the number of trucks sold last year.
We have,
216,000 = 3T + 39,000
Subtracting 39,000 on both sides.
216,000 - 39,000 = 3T + 39,000 - 39,000
177,000 = 3T
Divide 3 on both sides.
177,000 / 3 = 3T / 3
59,000 = T
The number of trucks sold last year is 59,000.
Thus the equation that can be used is 216,000 = 3T + 39,000 and the number of trucks sold last year is 59,000.

The polynomial, 3x - 4 + 5x², is a trinomial with a degree of 2.
What is a polynomial?An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.
Given:
We have the polynomial,
3x - 4 + 5x²
To find the degree of a polynomial:
We take the highest powered variable, and the order of that variable is equal to the degree of the polynomial.
Here, the highest power is 2.
So, the degree is 2.
And the polynomial has three terms.
So, the polynomial is trinomial.
Therefore, it is a trinomial with a degree of 2.

When x is decreased by 129 and then that number is multiplied by 129, the result is 129. What is the value of x?
Answer:
x=130
Step-by-step explanation:
(x - 129) * 129 = 129
Then solve
If x exists decreased by 129 and then that number exists multiplied by 129, the result exist 129 then the value of x exists 130.
How to estimate the value of x?In algebra, the letter "x" is frequently used to denote an unknown value. It is referred to as a "variable" or occasionally a "unknown."
Any of the algebraic expressions, including addition, subtraction, multiplication, and division, should be used. Bring the variable to the left and the remaining values to the right to estimate the value of x. To estimate the outcome, estimate the values.
If x exists decreased by 129 and then that number exists multiplied by 129, the result exist 129.
(x - 129) × 129 = 129
Divide both sides by 129
((x-129) × 129) / (129) = (129) / (129)
Simplifying the above equation, we get
x - 129 = 1
Add 129 to both sides
x - 129 + 129 = 1 + 129
x = 130
Therefore, the value of x exists 130.

Solve the equation −3=8x−4y for y.
What is the slope of the line that passes through the points (9,60 and (14,7)?
This is (y2-y1)/(x2-x1), y2 being 12, y1 being 7, x2 being -39 and x1 being 26. So if you plug in the points it would be: (12-7)/(-39-26). This solved equals: -5/65 which simplified equals: -1/13
-5(-x-2)=8x what is 6x
Expand.
-5x-10=8x
−5x−10=8x

Answer:
Natalie.
Step-by-step explanation:
there is a constant pattern in the cost of shirts and the number of shirts that can be bought.
for every 1 shirt you pay $15.
thus, to determine the amount you pay for 2 shirts.
2(X)=Y {y= the total cost of 'n' shirts,X= the cost of 1 shirt.}
so this can be expressed as n15=Y
3 shirts therefore will be 3($15)= $45
