Answer:
12:7 and 5:8
Step-by-step explanation:
first one just put the 2 together and the second one you have mr. brown and then the second number add the 2
Answer:
X = (J+M)/K
Step-by-step explanation:
Undo what has been done to the variable, in reverse order. The variable has been multiplied by K and M subtracted from the result. So, we first add M (to undo the subtraction), then we divide by K (to undo the multiplication).
KX = J +M . . . . . . M added to the given equation
X = (J + M)/K . . . . the result of that is then divided by K
___
Since these are all capital letters, we might assume they represent vectors and/or matrices. If so, the "divide by K" step needs to be "multiply on the left by K^-1, the matrix inverse of K."
Then your solution looks like
X = K⁻¹·(J + M)
Make the solutions equal to each other and then solve for x. Once you find x. Plug it back in to either side of the newly formed equation
The M.A.D of the set is 2.4.
Answer:
O = 41 degrees
Step-by-step explanation:
the sum of all angles in a triangle is always 180 degrees.
the graphic shows that this triangle has 2 equal sides. that means that both angles at O and at M are equal.
so, we know all three angles and can calculate
7y + 2×(4y - 15) = 180
7y + 8y - 30 = 180
15y = 210
y = 14
so, the angle at O is
O = 4×14 -15 = 56 - 15 = 41 degrees
