Answer: x=50
Step-by-step explanation:
Use the distributive property to multiply -0.2 by x-20.
-0.2x+4=44-x
Add x to both sides.
-0.2x+4+x=44
Combine -0.2x and x to get 0.8x.
0.8x+4=44
Subtract 4 from both sides.
0.8x=44-4
Subtract 4 from 44 to get 40.
0.8x=40
Divide both sides by 0.8.
x=40/0.8
Expand 40/0.8 approx 50 by multiplying both numerator and the denominator by 10.
X=400/8
Divide 400 by 8 to get 50.
x=50

Which equation represents a line that passes through (4, 1/3) and has a slope of 3/4.
Answer:
y = 3/4x - 2 2/3
Step-by-step explanation:
Are there choices?
y = 3/4x + b
1/3 = 3/4(4) + b
1/3 = 3 + b, b = -2 2/3
y = 3/4x - 2 2/3
the perimeter of a right angled triangle is 72cm. the lengths of its sides are in the ratio 3:4:5. work out the area of the triangle
The area of the given triangle will be 216 cm²
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.
We have been given that the perimeter of a right-angled triangle is 72cm. the lengths of its sides are in the ratio 3:4:5.
Let the side lengths of the given triangle be 3x, 4x, and 5x
The perimeter of the triangle = 3x + 4x + 5x
72 = 12x
x = 6
So first side length = 3(6) = 18 cm
So second side length = 4(6) = 24 cm
And third side length = 5(6) = 30 cm
Area of the triangle = (18 × 24)/2
Area of the triangle = 216 cm²
Therefore, the area of the given triangle will be 216 cm².

Kurt says that if he starts with the number n, multiplies it by the next whole number and then adds 3 he will get 45. N(n+1)+3=45 what number makes kurts equation true?
Answer:
6
Step-by-step explanation:
we start with:
n(n + 1) + 3 = 45
n² + 1n = 42
n² + 1n - 42 = 0
n can be either 6 or -7
(n - 6)(n + 7)
since we cannot have negative numbers, the answer should be 6, but we can verify which number fits our equation:
n = 7 ⇒ n(n + 1) + 3 = 45
7(7 + 1) + 3 = 59 WRONG
n = 6 ⇒ n(n + 1) + 3 = 45
6(6 + 1) + 3 = 45 ✓ CORRECT

6t - 9u = 10
2t + 3u = 4
solve by elimination please
Answer:
I got u= 1/9 and t=11/6
Step-by-step explanation:
hope this helps
The solution to the equation is t= 11/6 and u= 1/9.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. Every mathematical equation begins with L.H.S = R.H.S.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given equation:
6t - 9u = 10........(1)
2t + 3u = 4.........(2)
Multiply equation(2) with 3 we get
6t+ 9u = 12...(3)
Now, subtract (3)- (2)
18u= 2
u= 2/18
u= 1/9
and, 6t - 9(1/9)= 10
6t - 1= 10
6t= 11
t= 11/6

Which set of ordered pairs represents y as a function of x?
{(2,-1), (4, -2), (6, -3), (8, -4)}
{(0, 0), (1, 1), (1, 0), (2, 0)}
{(3, 3), (3, 4), (4, 3), (4, 4)}
{(1, -5), (1, 5), (2, -10), (2, -15)}
Answer:
{(2,-1), (4, -2), (6, -3), (8, -4)}
Step-by-step explanation:
The other ordered pairs have a common domain value which means they are not a function.
For example:
{(5,7), (5,8), (10,3)} would not be a function because the 5 is repeating
However
{(2,6), (4,6), (22,7)} would be function because there are no numbers in the x part of the ordered pair that repeat. (x,y)

Answer:
a
Step-by-step explanation:
Answer:
y=mx+b is the form in which these equations are. B represents the y intercept and M is the slope
currently to find slope we need to get y alone on the left side of the equation for all the answers:
A.y-4=3(x-2) -----> y-4=3x-6 (i also distributed) ----> y=3x-2
B. y+4=-3(x+2)----> y+4=-3x-6 -------> y=-3x-10
C. y-2=-3(x-4) --------> y-2=-3x+12 ------> y=-3x+14
D. y-4= -3( x-2) --------> y-4= -3x+6 ---------> y=-3x+10
All of these equations except A have a slope of -3 so A is already out and to find which one is valid we need to plug in the point (2, 4) for each of the equations
B. 4=-3(2)-10 ------> 4=-6-10----> 4=-16- not valid
C. 4 =-3(2)+14 -----> 4=-6+14------>4=8 not valid
D. 4=-3(2)+10 ----->4=-6+10 ------> 4=4 - Valid
Only D is correct
