Which shows the correct way to use the rule "multiply by the reciprocall for the expression below? 7 divided by 5/8

2 answers:

7 0

When asked to use the reciprocal in division you would get you first number (7) and then multiplying it by the 8/5 (instead of 5/8) which will eventually give you 56/5

Y=143.3(5)^2+1823.3(5)+6820

MA_775_DIABLO [31]

As the question is written, the correct answer is:

19519.

Explanation:

Our question states

y = 143.3(5)² + 1823.3(5) + 6820

To evaluate this, we use the order of operations (PEMDAS). There is nothing to be evaluated in parentheses, so P is taken care of.

The E part, exponents, is 5². This is 25, which gives us:

y = 143.3(25) + 1823.3(5) + 6820

Next we have M and D, multiplication and division (in the order they appear). Our multiplication is:

143.3(25) = 3582.5; and

1823.3(5) = 9116.5.

This gives us:

y = 3582.5 + 9116.5 + 6820

Lastly, we add these:

y = 12699 + 6820

y = 19519

Which statements are true for solving the equation 0.5 – |x – 12| = –0.25? Check all that apply.

Trava [24]

we have

$0.5-\left|x-12\right|=-0.25$

we know that

The absolute value has two solutions

Subtract $0.5$ both sides

$-\left|x-12\right|=-0.25-0.5$

$-\left|x-12\right|=-0.75$

Step 1

Find the first solution (Case positive)

$-[+(x-12)]=-0.75$

$-x+12=-0.75$

Subtract $12$ both sides

$-x+12-12=-0.75-12$

$-x=-12.75$

Multiply by $-1$ both sides

$x=12.75$

Step 2

Find the second solution (Case negative)

$-[-(x-12)]=-0.75$

$x-12=-0.75$

Adds $12$ both sides

$x=-0.75+12$

$x=11.25$

Statements

case A) The equation will have no solutions

The statement is False

Because the equation has two solutions------> See the procedure

case B) A good first step for solving the equation is to subtract 0.5 from both sides of the equation

The statement is True -----> See the procedure

case C) A good first step for solving the equation is to split it into a positive case and a negative case

The statement is False -----> See the procedure

case D) The positive case of this equation is 0.5 – |x – 12| = 0.25

The statement is False

Because the positive case is $0.5-(x-12)=-0.25$ -----> see the procedure

case E) The negative case of this equation is x – 12 = –0.75

The statement is True -----> see the procedure

case F) The equation will have only 1 solution

The statement is False

Because The equation has two solutions------> See the procedure
