Answer:  Plan A is less expensive for 50 minutes. About $6 less than Plan B

At 200 minutes, both plans cost $24

Step-by-step explanation:

1.)  Look at the numbers for minutes going across the bottom from left to right. Find 50. Follow the grid line up to where the blue line crosses it. (The blue line is lower than the red line so the cost is less.) Look at the numbers on the cost scale to verify the difference if someone asked. Plan A costs $6. Plab B costs $12 for 50 minutes.

2.) Look at where the Red and Blue lines intersect. That is where the plans cost the same amount of money for the same amount of minutes. Follow the grid line down from that point to find the number of minutes.

What is the value of p? Please provide an explanation, thanks!
Bezzdna [24]

Answer:

p=39.4°

Step-by-step explanation:

4a+4+75+p=180 (The sum of angles on a triangle is 180°)4a+p=180-4-75

4a+p=101

p+9a+2=180  (Angles of a straight line sums to 180°)

p + 9a = 178

Elimination can be used to find the value of one variable:

p+9a-(4a+p)=178-101

5a = 77

a=15.4

Now, the value of p can be found by using substitution:

4a+p = 101

4(15.4)+p=101

p = 101-61.6

p = 39.4

I hope this helps :)

enyata [817]

Answer:

t < 10.2

Step-by-step explanation:

Step 1: Add 6.2 to both sides.

  • t - 6.2 + 6.2 < 4 + 6.2
  • t < 10.2

Therefore, the answer is t < 10.2.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Hi:) I need help with part 9(ii) ? Thanks :)!
Goshia [24]

Answer:

see explanation

Step-by-step explanation:

Given

2BD = 7BT , then

2(d - b ) = 7(t - b) ← distribute both sides

2d - 2b = 7t - 7b ( add 7b to both sides )

2d + 5b = 7t, thus

2\left[\begin{array}{ccc}10.5\\10\\\end{array}\right] + 5\left[\begin{array}{ccc}0\\3\\\end{array}\right] = 7t

\left[\begin{array}{ccc}21\\20\\\end{array}\right] + \left[\begin{array}{ccc}0\\15\\\end{array}\right] = 7t

\left[\begin{array}{ccc}21\\35\\\end{array}\right] = 7t , thus

t = \frac{1}{7}\left[\begin{array}{ccc}21\\35\\\end{array}\right] = \left[\begin{array}{ccc}3\\5\\\end{array}\right]

Hence T = (3, 5 )
