Answer: Maria's age = 12
Father's age = 36
Step-by-step explanation:
Let Maria's age be p and her father's age be q
Then, we form equation from the question:
Father's age (q) = 3 x p
Therefore, q = 3p ......equation 1
Six years ago,
q - 6 = 5 (p - 6)
q - 6 = 5p - 30
q - 5p = -30 + 6
q - 5p = -24 ..........equation 2
Insert the value of q= 3p into equation 2
3p - 5p = -24
-2p = -24
Divide both sides by -2
p = -24/-2
p = 12
If Maria"s age is 12, then Father's age(q) = 3p will be 3 x 12= 36
Answer:
B. No the ordered pair does not satisfy the equation
Step-by-step explanation:
y = -9x - 2
Substitute the point in and see if it is true
-37 = -9(4) -2
-37 = -36 -2
-37 = -38
This is not true so the point is not a solution
Answer:
Step-by-step explanation:
Cost of 4 oranges = $x
cost of 1 orange= x/4
Cost of 10 oranges = x/4*10 = $ 2.5x
Cost of a custard apple = $1.25
Cost of n custard apple = 1.25*n = 1.25n
Cost of 4 bananas = $3
Cost of a banana = 3/4 = $0.75
Cost of (3n +1) bananas = 0.75*(3n+1) = 0.75* 3n + 0.75*1 = 2.25n + 0.75
Cost of fruits = 2.5x + 1.25 n + 2.25n + 0.75
= 2.5x + 3.50n +0.75

Answer:
x = 17
Step-by-step explanation:
Since the triangle is isoceles that means angle UTV is also 43 degrees. The sum of all angles in a triangle is 180 degrees. So construct this equation. 43 + 43 + 43 + 8x - 42 = 180. Now solve for x.
