Answer:

64/7 years

9.143 years

Step-by-step explanation:

Simple Interest  =  \\  \frac{Principal \times Rate \times Time}{100}

Time =  \frac{simple \: interest \times 100}{Principal \times Rate}

Principal = 400 \\ Rate = 14 \\ Time =  \\ simple \: interest = 512

Input the values

Time =  \frac{512 \times 100}{400 \times 14}  \\ Time =  \frac{51200}{5600}  \\

Time =  \frac{64}{7}  \\ Time = 9.142  \:  years \\ best \: answer \:  =  \frac{64}{7} years

Does x=5 satisfy 3(x+1)=3x+3
Svetradugi [14.3K]

Answer:

Yes

Step-by-step explanation:

Well let's solve it!

In order to solve this, plug in x into the equation.

Let's do the side on the LEFT of the equal sign first.

3(3+1) = 3(4) = 12

Now Let's do the side on the RIGHT of the equal sign.

3(3) + 3 = 9+3 = 12

So this means they are equal or congruent!

Un trapèze a une aire de 39 cm2. Sa grande base
V125BC [204]

Answer:

A = bh/2

39 = b*3/2

39*2 = b*3/2 * 2

78 = b*3

78/3 = b*3/3

26 = b.

Alors, la grande base est 26 cm et le petit base serait 26/3 = 8.67 cm arrondi.

A large tire company has 230 employees. There are 4 times as many mechanics as supervisors, and 10 more supervisors than account
Alex787 [66]
So your variable are these
x= # of accountants
x+10= # of supervisors
4(x+10)= # of mechanics
So you get the equation x+ (x+10) + (4x+40) = 230
and you solve for x
6x + 50 = 230
6x = 180
x=30
so accountants = 30
supervisors = 40
Mecahnics = 160
