Simplify the following expressions to have fewer terms 5x-3+4(4x-6)+2
Answer:
(21x-25)
Step-by-step explanation:
We need to find an equivalent expression for the following.
5x-3+4(4x-6)+2
We can solve it as follows:
5x-3+4(4x-6)+2 = 5x-3+16x-24+2
= 5x+16x-3-24+2
= 21x-25
So, the equivalent expression is equal to (21x-25).

Step-by-step explanation:
if the third term is 20 and 7th is 1.25, find the 11th term
Answer:
the 11th term is 0.0000488 or 4.88*10^-5.
Step-by-step explanation:
a3 = 20, a7 = 1.25
a7 = a3r^7-3
1.25 = 20r^4
r^4 = 0.0625
r = 4th root of 0.0625
r = 0.5
a3 = a1r^3-1
20 = a1(20)^2
400a1 = 20
a1 = 0.05
a11 = 0.05(0.5)^11-1 = 0.0000488 or 4.88*10^-5

A large jar contains 500 marbles. All of the marbles in the jar are either blue or yellow, and there are 3 times as many blue marbles as yellow marbles. Which equation can be solved to find the number of yellow marbles in the jar?
Answer:
The equation to solve to find the number of yellow marbles =
3y + y = 500
4y = 500
The number of yellow marbles = 125
Step-by-step explanation:
Let the number of
Blue marbles = x
Yellow marbles = y
A large jar contains 500 marbles.
x + y = 500
All of the marbles in the jar are either blue or yellow, and there are 3 times as many blue marbles as yellow marbles.
3y = x
Hence, we substitute 3y for ymx in the above equation
3y + y = 500
4y = 500
y = 500/4
y = 125
The number of yellow marbles = 125

My restaurant budget should not go over $100. If I bought main dish for $50 and $12 for each pizza, how many pizza's can I buy?
inequality :
50 + 12x ≤ 100
How many pizza's can I buy?
Answer:
x = 25
Step-by-step explanation:
50 + 12x <_ 100
12x <_ 100 - 50
12x <_ 50
x <_ 50 / 12
x <_ 25
You can buy about 4 pizzas.
I didn't use the way that I probably should have but you can subtract 50 from 100 and then divide the 50 by 12 and you will get 4.1666667.

Regan cycles 78 miles in 6 hours. His average speed for the first 30 miles is 15 miles per hour. Work out Regan's average speed for the last 48 miles.
Answer:
12 mph
Step-by-step explanation:
Given that:
Total distance traveled = 78 miles
Time taken, t = 6 hours
Average speed for first 30 miles = 15 mph
Time taken = distance / speed
Time taken = 30 / 15
Time taken = 2 hours
Average speed for last 48 miles = x
Time taken to travel last 48 miles = (6 - 2) = 4 hours
Average speed for last 48 miles :
Distance traveled / time taken
48 miles / 4 hours
= 12 mph

A video game regularly costs $29.95 is on sale for 15% off. About how much is the sale price of the game is you include 8% sales tax?
Answer:
$27.50
Step-by-step explanation:
First, find the cost with the 15% off sale
29.95(0.85)
= 25.46
Find the price with the sales tax:
25.46(1.08)
= 27.5
So, the sale price of the game with tax is approximately $27.50
Max gets a weekly allowance of $17. He spends $3 each week on snacks. He splits the rest of his allowance into equal amounts for his college fund and spending money. How much money does Max keep for spending money each week? $
Answer:
$7
Step-by-step explanation:
The amount max keeps for spending = 1/2(total allowance - amount he spends on snacks)
total allowance = $17
amount he spends on snacks = $3
Amount he would have for his college fund and spending money. = $17 - $3 = $14
Since he splits the amount equally between his college fund and spending money, the amount he would have for spending can be determined by dividing 14 by 2
$14/2 = $7

please help me find the area
Answer: 150m
Step-by-step explanation: you first remove 5 from 20 to get what you should multiply for your triangle then you get 15 and multiply it by 12 to get 180 then you divide by 2 since it’s a triangle, to get 90 then you find the area of the rectangle by multipling 5 by 12 to get 60 then 60+90=150
Answer:
150 meters
Step-by-step explain
He formula for a triangle is a=bh/2. it ends up being a=12x15/2=90.
The formula for a rectangle is 12x5=60.
You take both and add them together and you get 150.
So the answer is 150 meters.
