Answer:
1) Yes, 1/2 and 2
2) b=1/2 × t
t=2 × b
Step-by-step explanation:
1) Yes, because every package of a toy equals 2 batteries. The constant of proportionality is 1/2 and 2 because 1 ÷ 2 = 1/2 and 2 ÷ 1 = 2 (amount of toys divided by amount of batteries and vice versa)
2) b = 1/2t, because for every battery, there is 1/2 a toy.
t = 2b, because for every toy, there are 2 batteries
note: you can't actually have 1/2 a toy, but we write it like that for the sake of showing the relationship of toy to battery.
Find each unit rate. Round to the nearest hundredth if necessary.

Ms. Romero runs a house cleaning business. To save money, she bought a 1-gallon container of concentrated cleaner. She mixed the cleaner with 10 gallons of water. Then, she filled as many 1-pint spray bottles as she could. How many spray bottles did she fill?
Answer:
88 Spray bottles
Step-by-step explanation:
You need to find how many spray bottles Ms. Romero filled. But first, you need to know how much cleaning solution she had in all.
Ms. Romero mixed 1 gallon of concentrated cleaner with 10 gallons of water. So, she had 11 gallons of cleaning solution in all.
Ms. Romero filled each spray bottle with 1 pint of cleaning solution. So, find how many pints are in 11 gallons. There are 2 pints in a quart, and there are 4 quarts in a gallon. That means there are 8 pints in a gallon, so multiply 11 gallons by 8.
11×8=88
Ms. Romero had 88 pints of cleaning solution. Since she filled each spray bottle with 1 pint, she filled 88 spray bottles.

Solve:
y=3x
x=-2y+70
1- start with the original equation
x=2y+70
Let y =3x
x=2x 3x+70
simplify
x=6x+70
2-solve for x.
x=6x+70
Subtract 6x from both sides
x-6x=70
simplify x-6x to -5x
-5x=70
divide both sides by -5
x=- 70/5
simplify 70/5 to 14
x=-14
3- start with an original equation .
y=3x
Let x =-14
y=3x -14
simplify
y=-42
therefore
x=-14
y=-42
Solution of equations:
x = 10 ; y = 30
What is equation?An equation is a formula that represents that two expressions are equal, both expressions are connected with equality symbol '='.
Given equations,
y = 3x ------------(1)
x = -2y + 70 --------(2)
Substituting value of y in equation (2) from equation (1)
x = -2(3x) + 70
x = -6x + 70
x + 6x = 70
7x = 70
x = 10
Putting value of x in equation 1
y = 3(10)
y = 30
Hence, x = 10 and y = 30 are solution of the equations.

a = 73
b = 107
c = 73
d = 107
r = 152
s = 28
t = 152
u = 28
Answer:
b= 107, c=73 d=107. t=152 s= 62 u=62
Step-by-step explanation:
b= if you look at the top it says if you add a and b together you get 180, that means if you subtract a (73) you will get the degrees of b and then d is just the same as b so that is also 107. Then c has the same degrees as a.
T= since r is 152 and they are crossing each other that means they are the same degrees. And you and s are the same and they both are 62 degrees because they are an acute angle.
