The answer to the question is 752cm
Answer:
∠MNO = 51°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180, that is
3x + 15 + 2x + 25 + 5x + 10 = 180 ← simplify left side
10x + 50 = 180 ( subtract 50 from both sides )
10x = 130 ( divide both sides by 10 )
x = 13
∠MNO = 2x + 25 = (2 × 13) + 25 = 26 + 25 = 51°
There is a 1:10 chance of the needle landing on 9.
Answer:
5
Step-by-step explanation:
Hi,
find the x- and y-intercepts:
10x + 4y = 20
finding x-intercept when y = 0
10x = 20
x = 2 Pt(2,0) the x intercept
finding y-intercept when x = 0
4y = 20
y = 5 Pt(0,5) the y intercept
Let the number her brother has = x
She has 5 times as many so she has 5x
Together they have 42:
X + 5x = 42
Add x and 5x to get 6x:
6x =42
Divide both sides by 6:
X = 7
The brother has 7
Carla has 5*7 = 35
Answer: Carla has 35 notebooks
