Answer:
he would end up with 3000$ in 10 years with simple interest
Step-by-step explanation:
Answer:
The right answer is:
the addition property of equality and then the division property of equality
Step-by-step explanation:
Given equation and steps to solve it are:
Step 1: –3x – 5 = 13
Step 2: –3x = 18
Step 3: x = –6
In step two, -5 has to be removed from left hand side of the equation so additional property of equality will be used i.e. adding 5 on both sides
Similarly in the third step, to remove -3 with x , division property of equality will be used i.e. dividing both sides by -3
Hence,
The right answer is:
the addition property of equality and then the division property of equality
Answer:
No
Step-by-step explanation:
21 = 3p - 5
<u>Step 1</u> : Add 5 on both sides
21 + 5 = 3p
26 = 3p
3p = 26
<u>Step 2</u> : Divide 3 on both sides
p = 26/3
Hence, the solution of the given equation is 26/3, not 9.
28. Surface Area
This is some sort of house-like model so for every face we see there's a congruent one that's hidden. We'll just double the area we can see.
Area = 2 × ( [14×9 rectangle] + 2[15×9 rectangle]+[triangle base 14, height 6] )
Let's separate the area into the area of the front and the sides; the front will help us for problem 29.
Front = [14×9 rectangle] + [triangle base 14, height 6]
= 14×9 + (1/2)(14)(6) = 14(9 + 3) = 14×12 = 168 sq ft
OneSide = 2[15×9 rectangle] = 30×9 = 270 sq ft
Surface Area = 2(168 + 270) = 876 sq ft
Answer: D) 876 sq ft
29. Volume of an extruded shape is area of the base, here the front, times the height, here 15 feet.
Volume = 168 * 15 = 2520 cubic ft
Answer: D) 2520 cubic ft
X+ y = 10
2x = 2y+4
2x/2 = 2/2y+4/2
x = y + 2
x+y = 10
y+2+y=10
2y + 2 = 10
2y +2-2 =10-2
2y = 8
2y/2 =8/2
y = 4
x + y =10
x + 4 =10
x +4-4 =10-4
x = 6
Check
2x = 2y +4
2(6) = 2(4) +4
12 = 8+4
12= 12
