Answer: No
Step-by-step explanation:
Data: x+14<20
x=9? Is what your trying to find
<u>Step one, Isolate x by subtracting 14 on both sides</u>
X+14-14<20-14=X=6
Reason: Since you are trying to find if x=9, you have to isolate it. The way to do that is to get rid of +14 by subtracting it by 14. However, since what you do to one side you do to the other, you subtract +20 by 14 to get 6.
Since x=6 isn't x=9, the answer is No
Answer: No

P=A/(1+i/m)^mn
P=20000/(1+0.09/12)^12*4
P=(20,000)÷(1+0.09÷12)^(12×4)
P=13,972.28
Answer:
14 and 6
Step-by-step explanation:
Let's start by naming the first number x.
We can name the second number y.
We can set up equations to model our situation.
x+y=2x-8
x-y=2y-4
Let's simplify the equations.
x+y=2x-8
Subtract 2x from both sides
-x+y=-8
__________
x-y=2y-4
Subtract 2y from both sides.
x-3y=-4
Add the two equations together to eliminate x.
x-3y=-4
-x+y=-8
________
0x-2y=-12
-2y=-12
Divide both sides by -2.
y=6
The second number is 6.
Plug that back in.
x+6=2x-8
Subtract x from both sides
6=x-8
Add 8 to both sides
x=14
The first number is 14
From the given situation above, here is the solution:
Friend A. 13 hours x $ 6.95 = $90.35 x 8 weeks = $722.80
Friend B. 15 hours x $ 5.85 = $87.75 x 8 weeks = $702
Friend C. 18 hours x $ 5.25 = $94.5 x 8 weeks = $756
Friend D. 11 hours x $ 7.80 = $85.8 x 8 weeks = $686.40
Therefore, the individuals who reached their goal of saving $720 for a vacation are friend A and friend C. The correct answer is option A. A and C.
Answer: 0.04166
Step-by-step explanation:
1.25+(-1/3) +(-7/8)
1.25 - 1/3 - 7/8
= -8/24 - 21/24
= -8 - 21/ 24
= -29/24
= 1.25 - 29/24
= 1.25 - 1.20833
= 0.04166
