Answer:
Step-by-step explanation:
Given:
A shelf is built on a wall. The angles of the triangle are given as (x + 3)°, (2x - 18)° and 90°
We need to determine the value of x.
Value of x:
By triangle sum property, the angles in a triangle always add up to 180°
Thus, we have;
Simplifying, we get;
Subtracting both sides by 75, we get;
Dividing both sides of the equation by 3, we get;
Thus, the value of x is 35.
Find the volume of the large box:
15x25x29
375x29
10,875cm³
and the smaller box:
10x10x10
100x10
1,000
then subtract
10,875-1,000=9,875cm³ remaining
N + 1 = 4(n – 8)
Use distributive property for this part: 4(n – 8) ----> 4n - 32
n + 1 = 4n - 32
Get the variable on one side:
n + 1 = 4n - 32
-n -n
1= 3n - 32
Get the variable on its own:
1= 3n - 32
+32 +32
33 = 3n
Divide by 3 on both sides:
33/3 = 3n/3
n = 11
Answer:
y=2x+3
Step-by-step explanation:
the normal charge is 3 + 2 x number of days so this equation is the correct one.
