Step-by-step explanation:
Given the equation that represents this order expressed as;
The number of tiles = 12b + 38 where;
b is the the number of bundles ordered
If a customer needs 150 tiles, the total number of bundles ordered can be gotten by simply substituting The number of tiles into the modeled equation and find the value of b. This is as shown below;
On substituting;
150 = 12b + 38
12b = 150 - 38
12b = 112
b = 112/12
b = 9.33
b ≈ 9 bundles
We need to round up the problem because the number of tiles can not be in fraction but as whole numbers.
Y=2x-4
X+2y=10
Put y into the x equation
X+2(2x-4) =10
Expand and simplify
X+4x-8=10
5x-8 =10
5x=10+8
5x=18
X=18/5
Insert x into the original equation to get y
Y=2x-4
Y=2(18/5)-4
Y=16/5
The answer would be 42
42*3 = 126
126+5 = 131
3(n)+5=131
3(n)+5 -5= 131-5
3(n)=126
3(n)/3= 126/3
n= 42
Answer:
70
Step-by-step explanation:
we have the angle of vertex in the isosceles triangle = 180-2*bottom coner= 180-65/2=50
3 angles in the equilateral triangle are equal to 60
we have 50 + 60 +h =the angle of PQR =180
h=70
Answer:
Step-by-step explanation:
∠E = ∠B
6x - 39 = 3x
6x - 3x = 39
3x = 39
x = 39/3
x = 13
