[tex]\boxed {\sf Equation: 60 \textdegree +4x= 180 \textdegree} \\[/tex]
[tex]\boxed {\sf x=30}[/tex]
Step-by-step explanation:
The interior angles of a triangle must add to 180 degrees.
In this triangle, the angles are A, B , and C. So,
∠A + ∠B + ∠C= 180°∠A is 60 degrees, ∠B is 3x, and ∠C is x. We can substitute the values in.
60°+3x+x=180°This is the equation we can use to find the value of x.
We also have like terms: 3x and x that can be combined.
60° + (3x+x)= 180° 60° + 4x=180°We can use the equation to solve for x. We have to isolate the variable.
60 is being added to 4x. The inverse of addition is subtraction. Subtract 60 from both sides of the equation.
60°-60°+4x=180°-60°4x= 180°-60°4x=120°x is being multiplied by 4. The inverse of multiplication is division. Divide both sides by 4.
4x/4= 120°/4x= 120°/4 x=30Related Questions

SEE PICTURE
Answers
Step-by-step explanation:
Since g(x) = 2f(x), we apply scalling parallel to the y-axis by a factor of 2 onto f(x).
For x + 6 if x < 2,
It becomes 2(x + 6) if x < 2.
We have 2x + 12 if x < 2.
For x² + 4x - 15 if 2 <= x <= 5,
It becomes 2(x² + 4x - 15) if 2 <= x <= 5.
We have 2x² + 8x - 30 if 2 <= x <= 5.
For 5 - x if 5 < x,
It becomes 2(5 - x) if 5 < x.
We have 10 - 2x is 5 < x.

Review: Jen sells flowers. She charges $2 per flower plug a $3 flat delivery fee. How much will she make if she has to deliver 6 flowers?
Answers
Answer:
$30
Step-by-step explanation:
Answer:
$15 dollars
Step-by-step explanation:
We know that Jen sells flowers. We also know that she charges $2 dollar per flower plus a $3 dollar delivery fee.
The question is asking how much will Jen make if she sells 6 flowers. Since every flower costs 2 dollars, we can multiply the cost and amount.
6 * 2
12.
Jen makes 12 dollars just by the flower, and now the delivery fee which is an extra 3 dollars.
12 + 3
$15
