Evaluate 3/7r + 5/8s when r = 14 and s = 8
emmasim [6.3K]

\frac{3}{7}*r + \frac{5}{8} *s

let us first plug the values of r and s here

r=14 and s=8

\frac{3}{7}*14 + \frac{5}{8} *8

Now here we can cancel 14 and 7 as 7*2 =14 , also we can cancel 8 and 8 as 8*1 is 8, so our simplified new form is:

\frac{3}{1}*2 + \frac{5}{1} *1

Now we can multiply 3*2 and 5*1

3*2 =6

5*1=5

Next we add the two numbers

6+5 =11

So this is how we get the answer 11

The area of a square slice of cheese is 25 square inches. The perimeter of the slice of cheese is
maxonik [38]

Answer:

As Per Provided Information

Area of given square slice of cheese is 25 square inches .

We have been asked to determine the perimeter of the slice of cheese .

First we will find the side of square slice of cheese .

Let us assume the side of square slice of cheese be s .

Now Let's Solve

\boxed{\bf  \:Area_{(Square)}  = {Side}^{2}}

Substituting the value and we obtain

\sf \longrightarrow \: 25 =  {s}^{2}  \\  \\  \\  \sf \longrightarrow \:  \sqrt{25}  = s \\  \\  \\  \sf \longrightarrow \: s \:  = 5 \: inch

So, the side of square slice cheese is 5 inch

Now let's calculate the Perimeter of cheese

\boxed{\bf  \: Perimeter_{(Square)} = 4 \times side}

Substituting the value we obtain

\longrightarrow \sf \: Perimeter_{(Square)}  = 4 \times 5 \\  \\  \\ \longrightarrow \sf \: Perimeter_{(Square)}  =20 \: inches

<u>Therefore</u><u>,</u>

  • <u>Perimeter </u><u>of </u><u>square </u><u>slice </u><u>of </u><u>cheese </u><u>is </u><u>2</u><u>0</u><u> </u><u>inches </u><u>.</u>

What is the solution set of y = x2 + 2x + 7 and y = x + 7? A. {(0, 7), (-1, 6)} B. {(0, 7), (-7, 0)} C. {(0, 7), (1, 8)} D. {(-2
Elena-2011 [213]

Answer:

A.

Step-by-step explanation:

If

y=x^2+2x+7 AND

y = x + 7, then by the transitive property of equality:

x^2+2x+7=x+7

We can solve for the values of x by getting everything on one side of the equals sign and then solving for x:

x^2+x=0

We can factor out the common x to get:

x(x + 1) = 0

which tells us by the Zero Product Property that either

x = 0 and/or x + 1 = 0 and x = -1

We are expecting 2 solutions for x since this is a second degree polynomial.  We will sub both -1 and 0 into y = x + 7 to solve for the corresponding values of y

y = 0 + 7 so

y = 7 and the coordinate is (0, 7)

y = -1 + 7 so

y = 6 and the coordinate is (-1, 6)
