Evaluate : 5-3(x-1) when x=7

Answers

Answer 1

Answer:

The value of 5-3(x-1) when x=7 is -13.

What is Evaluate meaning?

Evaluation is nothing but to solve an algebraic expression means to find the value of an expression by replacing the value of the variable in it.

To evaluate the expression value, we simply substitute the variable from its given value and simplify the expression by using order of operations.

In our case, the given expression is:

5-3(x-1)

Substitute the given number i.e., 7 for the variable in the expression:

5-3(7-1)

Solve the bracket first:

5-3(6)

Now solve the multiplication part:

5 - 18

Finally Subtract 5 from -18, we get:

-13

Hence the final value of the expression is -13 at x=7.

Answer 2

Answer:

Answer:

$\boxed{ \bold{ \boxed{ \sf{ - 13}}}}$

Step-by-step explanation:

Given , x = 7

let's find :

$\sf{5 - 3(x - 1)}$

Plug the value of x

⇒ $\sf{5 - 3(7 - 1)}$

Subtract 1 from 7

⇒ $\sf{5 - 3 * 6}$

Multiply the numbers

⇒ $\sf{5 - 18}$

Calculate

⇒ $\sf{ - 13}$

Kim, Kyle and Katie contribute the same amount to their fathers gift. Their older sister contributes $12. how much does Kate contribute is the total is $30.

Answers

The total cost was $30.00. The oldest sister contributed $12.00 leaving $18.00. The other two sisters divided this and it was $9.00 each

it's would be $6.00 dollars each because 30-12=18 then divide 18 by 3 and you get 6

What is a pair of complex numbers called?

Answers

Answer:Complex numbers in the coordinate plane. Each complex number x + yi corresponds to a number pair (x, y) in the plane, so we may say that the complex numbers form a two-dimensional collection. The two coordinates of the pair (x, y) are called the real part and the imaginary part of the complex number.

Doris put $4000 in a 5year CD paying 6% interest compounded monthly. After 2 years, she withdrew all her money, and as an early withdrawal penalty, she paid back all the interest she made during the first year. How much money was Doris left with? Show your work.

Answers

Answer: Doris was left with $4216.93.

Step-by-step explanation:

Since we have given that

Principal amount = $ 4000

Rate of interest = 6%

He put $4000 in a 5 year CD paying 6% interest compounded monthly.

After 2 years, she withdrew all her money.

so, Amount after 2 years when it is compounded annually.

$A=4000(1+(6)/(12* 100))^(12* 2)\n\nA=4000(1+0.005)^(24)\n\nA=4000(1.005)^(24)\n\nA=\$4508.64$

As an early withdrawal penalty, she paid back all the interest she made during the first year.

$Interest=4000[(1+0.005)^(12)-1]\n\nInterest=\$246.71$

Amount left with Doris is given by

$\$4508.64-\$246.71\n\n=\$4261.93$

Hence, Doris was left with $4216.93.

for APEX it is going to be 4261.93

Select the proper order from least to greatest for 1/2, 5/6, 2/7, 4/2?

Answers

Answer: Proper order form least to greatest is given by

$(2)/(7),(1)/(2),(5)/(6),(4)/(2)$

Step-by-step explanation:

Since we have given that

$(1)/(2),(5)/(6),(2)/(7),(4)/(2)$

We need to write it in proper order from least to greatest.

For this we are required to take the L.C.M. of denominators:

1) L.C.M. of 2,6,7,2 = 42

2) Make the denominator 42:

$(1)/(2)* (21)/(21)=(1* 21)/(2* 21)=(21)/(42)\n\n(5)/(6)* (7)/(7)=(5* 7)/(6* 7)=(35)/(42)\n\n(2)/(7)* (6)/(6)=(2*6)/(7* 6)=(12)/(42)\n\n(4)/(2)* (21)/(21)=(4* 21)/(2* 21)=(48)/(42)$

From least to greatest :

$(12)/(42),(21)/(42),(35)/(42),(48)/(42)\n\n(2)/(7),(1)/(2),(5)/(6),(4)/(2)$

the least is 2/7 then 1/2 then 5/6 and the greatest is 4/2
