Use the Distributive Property to Simplify. However, to make it easier, write out the equation like this.
-1(-7y+12)
This makes it so it simplifies to 7y-12.
H=hats
s=shirts
Here, you need to do 2 equations.
h+s=150
3h+5s=590
3h+5(150-h)=590
3h+750-5h=590
-2h=-160
h=80
150-80=70 so s=70
i am sorry, this is all i know, but you need to make an equation to graph it.
Answer:
ill keep a look oiut for the answer
Step-by-step explanation:
It is A.
Since his brother is 11 years younger, you would subtract 23-11=12
So Larry is 12 years old.
Answer:
x=70
y= 30
z= 10
Step-by-step explanation:
X + 110 = 180 since they form a straight line
Subtract 110 from each side
x+110 -100 = 180-110
x = 70
Y + 110 + 40 = 180 since the three angles of a triangle add to 180
y+150 = 180
Subtract 150 from each side
y+150-150 = 180-150
y = 30
A + B+ C = 180 since the three angles of a triangle add to 180
90 + y+z+ 40 =180
90 + 30+z + 40=180
Combine like terms
170 +z = 180
z = 180-170
z = 10
