Answer:

8.4

Step-by-step explanation:

1 orange → x

1 apple → y

\frac{\begin{matrix}\space\space&5n&+&7y&=\textbf{6.90}\\ +&5n&+&20y&=\textbf{16.00}\end{matrix}}{\begin{matrix}\space\space&\space\space&\space\space&\space\space&\textbf{+13y = +9.1}\end{matrix}}\\y = 0.7

↓

3n + 12y = 9.6\\3 (n+4y) = 3 (3\cdot2)\\x + 4y = 3.2\\5 (n+4y) =5 (3\cdot2)\\5x + 20y = 16

12 apples → 12 \times 0.7

→→→→→ 8.4

Can a triangle have angle measures as 140,43, and 7
Mariulka [41]

The angles in a triangle always add up to exactly 180 degrees.  To see if this can be a triangle, add up the given angle measures.  If the sum is not 180, then it cannot be a triangle.

140+43+7=190

A triangle CANNOT have the angles measures as 140, 43, and 7.

Hope this helps!!

The backboard of the basketball hoop forms a right triangle with the supporting rods, as shown. Use the
svlad2 [7]

Answer:

9.14 inches.

Step-by-step explanation:

From the question,

Assuming the diagram attached, is similar to diagram required to support the question,

From the diagram,

Applying pythagoras theorem

a² = b²+c²...................... Equation 1

Where a = 13.4 in, b = x in, c = 9.8 in.

Substitute these values into equation 1

13.4² = x²+9.8²

x² = 13.4²-9.8²

x² = 179.56-96.04

x² = 83.52

x = √(83.52)

x = 9.14 inches

Hence the distance between the rods is 9.14 inches

Identify the slope and y-intercept of each of the following lines. Then graph each line.
lesya692 [45]

Answer:

Yes, but you have to write what the slope and y-intercept of the equation is as well.

Step-by-step explanation:

(Not sure if you wanted the full answer or just if you should graph it but I'm putting it here anyways :^P)

First convert the equation from standard form to slope-intercept form.

5x-3y=18 -> 5x-18-3y -> 5/3x-6=y

5/3x is the slope and 6 is the y-intercept!

Then graph the equation.
