Answer:

x = -2, y= 3

Step-by-step explanation:

y = 4x + 11

y = -2x - 1

Because both equations are equal to y, we can set them equal to each other

4x + 11 = -2x - 1

Add 2x to each side

4x+2x +11 = -2x+2x -1

6x +11 = -1

Subtract 11 from each side

6x+11-11=-1-11

6x = -12

Divide each side by 6

6x/6 = -12/6

x = -2

Now we need to find y

y = -2x-1

y = -2(-2)-1

=4-1

Answer:

9.95 + 8.01p ≤ 50, so p ≤ 5

Step-by-step explanation:

So to set up the equation you must first add 9.95+ because every order has a shipping fee of 9.95

Then you put in 8.01 is less than or equal to 50 because p representing a number of players is being multiplied by the unit cost 8.01. Trace is also wants the total to be under 50 dollars

Finally p is less than or equal to 5 because if you put the value 5 in for p in the equation, the equation is true.

The whole equation is 9.95 + 8.01p ≤ 50, so p ≤ 5

Answer:

16.5 square feet

Step-by-step explanation:

The logo consists of

rectangle with sides of 3 ft and 1.5 ft;
trapezoid with bases 3 ft, 4 ft and height of 3 ft;
triangle with base of 1.5 ft and height of 2 ft.

The area of rectangle:

$A_{rectangle}=1.5\ ft\times 3\ ft=4.5\ ft^2$

The area of trapezoid:

$A_{trapezoid}=\dfrac{3\ ft+4\ ft}{2}\times 3 \ ft=3.5\ ft\times 3 \ ft=10.5 \ ft^2$

The area of triangle:

$A_{triangle}=\dfrac{1}{2}\times 1.5\ ft\times 2 \ ft=1.5\ ft^2$

Hence, the area of logo:

$A=A_{rectangle}+A_{trapezoid}+A_{triangle}=4.5\ ft^2+10.5\ ft^2+1.5\ ft^2=16.5\ ft^2$

A, B and C start at the same time in the same direction to run around a circular stadium. A completes a round in 252 seconds, B

grin007 [14]

Answer:

D. 46 minutes 12 seconds

Step-by-step explanation:

To find the answer, we need to calculate the least common multiple of 252,308 and 198

252= $2^{2}$ × $3^{2}$ ×7

308= $2^{2}$ ×7×11

198=2× $3^{2}$ ×11

Then least common multiple is

$2^{2}$ × $3^{2}$ ×7×11=2772 seconds

2772 = 46×60 + 12

Therefore 2772 secondsis equal to 46 minutes 12 seconds.
