Answer:
Step-by-step explanation:
1)y=-6x-14 ---------(i)
-x-3y=-9 ---------- (ii)
Substitution method:
Substitute y value in equ (i)
-x -3*(-6x-14) = -9
-x - 3*-6x -3*(-14)= -9
-x + 18x + 42 = -9
17x = -9 -42
17x = -51
x = -51/17
x = -3
Substitute x value in equation (i)
y = -6*-3 -14
y =18-14
y = 4
Answer:
12
Step-by-step explanation:
Length of a circle = circumference = 2πr = 24π
Radius (r) = 24π/2π
= 12cm
Answer:
1/8
Step-by-step explanation:
1/6 × 3/4
Multiply across top, then bottom
1×3=3
6×4=24
Then reduce if necessary.
3/24
Divide top and bottom by 3
3÷3=1
24÷3=8
You should get 1/8
Answer:
A = 66.5 in²
Step-by-step explanation:
There are a few different equations to find the area of a rhombus. If you are given the measurements of the two diagonals, you can use the following formula:
Area (A) = 
Using this formula, you can multiply the measures of the diagonals and then divide by 2:
area =
