Expand 3(x+ 2.3)
Expand 1/3(9x-12)
Answer:
3x+6.9 and 3x-4
Step-by-step explanation:
since 3 x x is 3x and the sign in the bracket is addition you place it there then place 3 x 2.3
being 6.9.
1/3 x 9is 9/3 and 3 can multiply both sides to get 3/1 or 3 then bring the minus and 1/3 x 12 is 12/3 3 can multiply both sides to get 4/1 or 4
A student is 1.75m tall and is trying out for the football team. He kicks the football straight up
in the air from his outstretched arms at a height of 1 m. If the ball hits him on the head on the
way back down 3 seconds later, what was the football's initial velocity?
Answer: see below
Step-by-step explanation: Initial velocity = terminal velocity. At the top of travel, the velocity is 0 as the ball is motionless. Then it travels 3 seconds (due to gravity). Grav is 9.8m/sec squared. So 1st second = 9.8m. 2nd second is 2x9.8m. 3rd second is 3x9.8m = 29.4 m/sec.
Savannah is deciding between two parking garages. Garage A chargers an initial fee of $9 to park plus $1.50 per hour
Answer: 4 hours
Step-by-step explanation:
Assume x is the number of hours taken.
Garage A would therefore charge a total of:
= $9 + $1.50 * x
= 9 + 1.50x
Garage B would charge:
= $5 + $2.50 * x
= 5 + 2.50x
To find the number of hours it would take for them to be the same, equate both equations:
9 + 1.50x = 5 + 2.50x
9 - 5 = 2.50x - 1.50x
4 = 1x
x = 4 hours
That cost would be:
= 9 + 1.50 * 4
= 9 + 6
= $15
Devin bought a new car
for $19,024 and it was
20% off. Determine the
original price of the car.
Answer:
$23780
Step-by-step explanation:
Given data
Let the original price be x
discount= 20%
price= $19,024
so that
20/100*x=x-19,024
0.2x= x-19,024
19,024=x-0.2x
19,024=0.8x
x= 19,024/0.8
x=23780
Hence the original price is $23780

Given that a = ( − 6 7 ) and b = ( − 1 − 3 ) . If a − b = ( x y ) , work out the values of x and y .
Answer:
x = -5 , y = 10
Step-by-step explanation:
As given ,
a = ( x₁ , y₁ ) = ( -6, 7)
b = ( x₂ , y₂ ) = (-1, -3)
For a -b = ( x₁ - x₂ , y₁ - y₂ )
= ( -6 - (-1) , 7 - (-3) )
= ( -6 + 1 , 7 + 3 )
= ( -5 , 10 )
⇒ a - b = ( -5, 10 ) = ( x, y)
∴ we get
x = -5 , y = 10

Friday night a pizza parlor sold 5 large pizzas and some medium pizzas the pizza parlor made a totle of 291 how many mediom pizas werer sold wright and eqacion
Answer: 24
Step-by-step explanation:
The other information regarding the question is that the Medium pizza cost $9 while the Large pizza cost $15.
The number of medium sized pizza that Wright sold will be represented by x.
(5 × $15) + ($9 × x) = $291
$75 + 9x = $291
9x = $291 - $75
9x = $216
x = $216/9
x = 24
He sold 24 medium pizza

My sister is 18 years old. My brother says that his age minus eighteen is equal to my sister's age. How old
is my brother?
Enter an equation, using b as your variable, to find how old my brother is.
The equation is
My brother is
years old.
Answer:
The brother is 36 years old.
Step-by-step explanation:
b = brothers age
b - 18 = 18 | Given
b = 36 | Add 18 to both sides to cancel out -18 and get his age.
Answer:
36 years old or b-18 = 18
Step-by-step explanation:
Since there is an 18 year difference between the brother and the sister, all you have to do is subtract 18 from how hold the brother is. Since we know that the age of the sister is 18, the equation needs to be equal to 18. Using this, we know the equation is b - 18 = 18. When we add 18 to both sides we get that b=36.

What is 8 4/9 as a decimal?
The decimal is 8.44444
What is decimal?Decimals are a set of numbers lying between integers on a number line. They are just another way to represent fractions in mathematics. With the help of decimals, we can write more precise values of measurable quantities like length, weight, distance, money, etc. The numbers to the left of the decimal point are the integers or whole numbers and the numbers to the right of the decimal point are decimal fractions. If we go right from ones place, the next place will be (1/10) times smaller, which will be (1/10)th or tenth place value.
Given:
8 4/9
Change the mixed fraction in normal fraction
=9*8+4/9
=72+4/9
=76/9
