Answer:
22
Step-by-step explanation:
If x = 5, then plug 5 in for x .
3(5) + 7
15 + 7 = 22
-12/-9=y/-4
cross multiply
-9y=48
divide by 9 on each side
y= -5.33
Answer:
choice a is the answer
0.17
Step-by-step explanation:
Answer:
There is no solution.
Step-by-step explanation:
To solve, use the order of operations. Follow them until you solve for x or just numbers remain.
-(6x + 6) + 2 = -6x - 3
-6x - 6 + 2 = -6x - 3
-6x - 4 = -6x - 3
-4 = -3
The answer is no solution since this is a false statement.
Answer:
145 yd²
Step-by-step explanation:
There will be dour triangular faces. For a triangle, area is given as
A=½bh where b is base and h is height. The base will be 5 yards and h is 12 yards hence for one triangular face, area will be ½*5*12=30 yd²
Since they are four similar triangles, area of triangular faces will be 30*4=120 yd²
The surface area of a square base is given by
A=a*a=a² where a is the dimension of one side. Given that the meaurement is 5 yards then A=5²=25 yd²
Total area will be the sum of triangular and square faces hence 120+25=145 yd²
