Virty [35]

Answer:

Marta need to score at least 94 to receive an average of 90 or higher considering all five tests.

Explanation:

Marks received by Marta in four tests = 86, 84, 97 and 89

Let mark received in fifth test be x

We have average of five test is more than or equal to 90

So we have

$\frac{86+84+97+89+x}{5} \geq 90\\ \\ 86+84+97+89+x\geq 450\\ \\ x\geq 94$

So Marta need to score at least 94 to receive an average of 90 or higher considering all five tests.

Find f(x) =32<br> f(x)=3x-1

SIZIF [17.4K]

Answer:

Given f(x)=32

So we can substitute 32 in place of 'x'

So, f(x)=3x-1

= f(x)=3(32)-1

= f(x)=96-1

= f(x)=95

f(x)=3x-1 = 95

Anni [7]

Answer:

$\large \boxed{\$1200.00}$

Step-by-step explanation:

Let the office charge = x

Amount paid by Medicare = ⅞x

Amount paid by Ross = ¼(⅞x) = $262.50

Solve for x

$\begin{array}{rcrl}\dfrac{1}{4} \left(\dfrac{7}{8}x \right ) & = & \$262.50 & \\\dfrac{7}{32}x & = & \$262.50 & \text{Multiplied the fractions}\\\\7x & = & \$8400.00 & \text{Multiplied each side by 32}\\x & = & \mathbf{\$1200.00} & \text{Divided each side by 7}\\\end{array}\\\text{The office wanted to charge } \large \boxed{\mathbf{\$1200.00}}$

Check:

$\begin{array}{rcl}\dfrac{1}{4} \left(\dfrac{7}{8}\times \$1200.00 \right ) & = & \$262.50\\\\\dfrac{1}{4} \left(\$1050.00 \right ) & = & \$262.50\\\\\$262.50 & = & \$262.50\\\end{array}$

OK.
