A circle is 360 degrees so you add 12 and 9 and 60 witch gives you 81 then you subtract 81 from 360 witch is 271 then put a decimal in there 27.1 so the 60 degrees is about 27
hope this helped:)
Answer:
x=-p+q+y
Step-by-step explanation:
-x=p-q-y
x=-p+q+y
You have to combine liked terms. the answer is -5x- -1, which is essentially -5x+1 because two negative is a positive
<span>Let the price of mini golf be $x
Let the price of batting cage be $y
Sylvester:
Price for 5 rounds of mini golf = 5x
Price for 4 rounds of batting cage =4y
Total price paid =$60
Therefore the required equation is:
5x+4y=60 ----------(1)
Lin:
Price for 3 rounds of mini golf =3x
Price for 6 rounds of batting cage =6y
Total price paid = $45
Therefore the required equation is:
3x+6y=45 ----------(2)
Let's use elimination method to find the prices.
Multiply the first equation by 3
15x + 12y =180 -------(3)
Multiply the second equation by 5
15x +30y=225 --------(4)
Subtract equation (4) from equation (3) to eliminate x
15x+12y=180
15x+30y=225
-___-___-________
-18y = -45
y=45/18 =2.5
Substituting y in equation (1)
5x+4(2.5)=60
5x+10=60
5x=50
x=50/5 = 10
Price of mini golf =$2.5
Price of batting cage =$10.00</span>
Answer:
The value of the expression is - 5.
Step-by-step explanation:
(-2x +10) - (-6x + 5y + 12) + (x +8y - 16)=
-2x+10+6x-5y-12+x+8y-16=
(-2x+6x+x)+(-5y+8y)+(10-12-16)=
5x+3y-18
if x=5 and y=-4 then
5*5+3*(-4)-18=25-12-18=25-30=-5
