When i calculated it , it says 993.813
Answer:
B. 152 + 7
Step-by-step explanation:
(8x + 16) + (7x - 9)
8x + 16 + 7x - 9
15x + 16 - 9
15x + 7
None of these options have this answer, so we see A and B:
A. x + 7
B. 152 + 7
It can't be A because we have 15x and A is x + 7
By process of elimination we have B. 152 + 7
x = 10 and 2/15
Answer:
-6(x-2)=-7(x-3) = False x = 9
Step-by-step explanation:
Solve for x:
-6 (x - 2) = -7 (x - 3)
Expand out terms of the left hand side:
12 - 6 x = -7 (x - 3)
Expand out terms of the right hand side:
12 - 6 x = 21 - 7 x
Add 7 x to both sides:
7 x - 6 x + 12 = (7 x - 7 x) + 21
7 x - 7 x = 0:
7 x - 6 x + 12 = 21
7 x - 6 x = x:
x + 12 = 21
Subtract 12 from both sides:
x + (12 - 12) = 21 - 12
12 - 12 = 0:
x = 21 - 12
21 - 12 = 9:
Answer: x = 9
Answer:
mark=$2400 &Saul=$4800
Step-by-step explanation:
For mark:
p=$12000
r=4%
t=5 years
I=prt/100
12000*4*5/100= 2400
For Saul:
p=$10000
r=6%
t=8 years
SI=prt/100
10000*6*8/100= 4800
You could draw a string of 13 boxes.
Then separate these 13 boxes into groups of 3 as far as possible:
(4 boxes) (4 boxes) (4 boxes) (1 box left)
This illustrates the fact that 13/3 = 4 1/3.
