lesson one
9y+2=29
y=3
3/4(5x-4)=12
x=4
the out put of a function is 8 less than -3 times the input. find the input when the out put is -23
x=5
g=x+c+y, for x
g-c-y=x
what is the distributive property
Mr.Betterly chooses best answer
x/4-3=5
x=32
name the properties of equality
Addition properties of equality
subtraction properties of equality
multiplication properties of equality
division properties of equality
The out put of a function is 12 more than 5 times the input. Find the input when the out put is -8
x=-4
kx=w-v for x
x=w-v over k
what do exponents do
multiply a number by itself over the certain amount of times
2x-1/5=7
x=18
word this out 9x-13x+7=31
nine,x minus thirteen,x plus seven equals thirty one
You are driving to a vacation spot that is 1500 miles away. including rest spots, it takes you 42 hours to get to the vacation spot. you estimate you were going 50 miles per hour. How many hours were you not driving
12 hours of rest
x-k=y-w for x
x=v-w+k
t-h+e=g-o solve for g
t-h+e+o=g
r+(-11)=-3
r=8
23x-8-14x=10
10=10
You helped a friend move a short distance recently. the friend rented a truck for 15$ an hour and rented a dolly for 5$. Your friend paid 80$ for the rental how long did your friend rent the truck for?
u=ka+b for a
u-b/k=a
how many people are in the room right now including Mr.Betterly
have to find out
-7=2+n/2
-2/-16=n
34a-4(5a+2)=36 solve for a
a=22/7
Your school band needs to buy new recording equipment. The equipment will cost 3,000$. the band has collected 1200$ in previous fundraisers. if the band sells sandwiches for $5 each, how many sandwiches will they need to sell to raise the remaining funds?
xk=w+v solve for x
x=w+v-k
1-100 added together estimate team closes gets points
