Answer:
21
Step-by-step explanation:
3×9=27
27-6=21
u do 9× 3 (nine times the quantity of three) is 27 then 3 less then double a number so u take 27 - 3x2= 6 (27-6) an it gives u 21
Answer:
21
Step-by-step explanation:
9×3=27
3×2=6
27-6=21

Un tren de carga va a una velocidad constante de 60 km/h y pasa por un túnel de 340 m de largo. ¿Cuánto mide el tren, si es que para cruzar completamente el túnel se demora tres cuartos de minuto?
Answer:
the length would be 410.15m
Step-by-step explanation:
The computation of the length is as follows;
Length = 340m
Let us assume x be train length
Now
the distance traveled by the train is (L + x)
d = L + x
v = 60 km ÷ h
= 16.67 m / s
And,
t = (3 ÷ 4) (60)
= 45s
Now
d = vt
L + x = (16,67) (45)
x = (16,67) (45) - 340m
x = 410.15m
Hence, the length would be 410.15m
What is the function of this graph?
Answer:
x=y^2-2
Step-by-step explanation:
This graph, is a parabola that opens to the right.
To answer this question, we just use the vertex form of a sideways parabola- x=a(y-k)^2+h.
In this case, the vertex is (-2, 0), and our value of a is 1, since it opens to the right.
This gives us: x=1(y-0)^2+(-2)
Which simplifies to: x=y^2-2.
Also, the answer to the previous two questions are wrong.
The D value (Domain) is actually [2, ∞)
The R value (Range) is actually "All real numbers" (-∞, ∞)

For two days, your boss decides to double the amount you make if on day 1, you make $70 dollars and on day 2, you make$80 dollars, write an expression for the total commission you earn?
Answer:
300
Step-by-step explanation:
Day 1: $70
Day 2: $80
Total commission = day 1 × 2 + day 2 × 2
= 70 × 2 + 80×2
= 140 + 160
= 300
Or
Total commission = 2(day 1 + days 2)
= 2(70 + 80)
= 2(150)
x = 300

What equation describes the circle that is centered at (8, 3) and has a radius of 9
Answer:
(x-8)²+(y-3)² = 81Step-by-step explanation:
The general equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the centre of the circle
r is the radius
Given the centre (8, 3) and the radius of 9, the equation of the circle will be;
(x-a)²+(y-b)² = r²
(x-8)²+(y-3)² = 9²
(x-8)²+(y-3)² = 81
hence the required equation is (x-8)²+(y-3)² = 81

Consider the diagram below of an equilatera triangle.
Answer:
4 = n.
13 ft.
Step-by-step explanation:
An equilateral triangle means that all of the sides are equal.
This means: 2n + 5 = 3n + 1 = 5n -7
You can pick two of those sides to set up an equation to solve for n.
For example, 2n + 5 = 3n + 1.
Then you will need to isolate the variable.
Subtract 1 from each side to get 2n + 4 = 3n.
Subtract 2n from each side to get 4 = n.
Substitue 4 for n into one of the equations.
2n + 5
2(4) + 5
8 + 5 = 13
Each side is 13 ft.

A tree planter can plant 40 trees in 8 hours.
How many trees can a tree planter plant in 2
hours?
Answer:
He can plant 10 trees in 2 hours.
Step-by-step explanation:
First you need to find the number of trees he can plant in an hour.
For this purpose, we will divide 40 by 8 to get an idea about how many he can plant in an hour.
Trees planted in an hour = 40/8 = 5
Now for 2 hours = 5*2 = 10 trees.
Richard Brian puts $30 worth of gas in his truck. The price per gallon was $2.50. Which equation can be solved to find the number of gallons Richard Brian's purchased?
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that Richard Brian puts $30 worth of gas in his truck and the price per gallon was $2.50.
The equation that can be solved to find the number of gallons Richard Brian's purchased will be the worth of gas in the truck divided by the price per gallon. This will be:
x = 30 / 2.50
where x = number of gallon.
= 12 gallons
The Sugar Sweet Company is going to transport its sugar to market. It will cost $3500 to rent trucks, and it will cost an additional $225 for each ton of sugar transported.
Let C represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported. Write an equation relating C to S. Then use this equation to find the total cost to transport 16 tons of sugar.
Answer:
Equation: $3500+$225s=c
To transport 16 tons of sugar the Sugar Sweet Company will need $7100
Step-by-step explanation:
Notes:
$3500 to rent truck
$225 for each ton of sugar
S is sugar in tons
C is total
Truck is a set cost so you leave it alone
Sugar in the truck is $225 each ton in this case its 16 tons
$3500+$225S=C
Plug in: $3500+$225(16)=C
$3500+$3600=C
C=$7100

Please answer them all I will award brainliest answer <3
Answer:
Step-by-step explanation:
4(y+3)+2(y+7) = 2(3y`=13)

Colin was thinking of a number. Colin halves it and gets an answer of 5.2. What was the original number?
Answer: 10.4
Step-by-step explanation:
Let the number that Colin is thinking of be represented as x.
We are informed that Colin halves the number and gets an answer of 5.2. This can be written as:
x ÷ 1/2 = 5.2
0.5x = 5.2
Divide through by 0.5
0.5x/0.5 = 5.2/0.5
x = 10.4
The number is 10.4
