Answer: 10 ounces
Step-by-step explanation:
Given
The label says to mix 5 ounces of oil with 11 gallons of gasoline
for 22 gallons of gasoline that is, double the previous amount, oil required would also be doubled.
Oil required would be 10 ounce.
2x+3y=15
X+y=6
Simultaneously equations
Answer:
Step-by-step explanation:
Let's solve your system by substitution.
2x+3y=15;x+y=6
Rewrite equations:
x+y=6;2x+3y=15
Step: Solvex+y=6for x:
x+y=6
x+y+−y=6+−y(Add -y to both sides)
x=−y+6
Step: Substitute−y+6forxin2x+3y=15:
2x+3y=15
2(−y+6)+3y=15
y+12=15(Simplify both sides of the equation)
y+12+−12=15+−12(Add -12 to both sides)
y=3
Step: Substitute3foryinx=−y+6:
x=−y+6
x=−3+6
x=3(Simplify both sides of the equation)
Answer:
x=3 and y=3
Answer:
x = 3, y = 3
Step-by-step explanation:
Given the 2 equations
2x + 3y = 15 → (1)
x + y = 6 → (2)
Multiplying 2) by - 2 and adding to (1) will eliminate x
- 2x - 2y = - 6 → (3)
Add (1) and (3) term by term to eliminate x
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
2x + 3(3) = 15
2x + 9 = 15 ( subtract 9 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3

5(2)^x=40 what is the value of x
Answer:
x=3
Step-by-step explanation:
5(2)^x=40
Divide each side by 5
5 /5 *(2)^x=40/5
2^x = 8
Rewriting 8 as 2^3
2^x = 2^3
The bases are the same so the exponents are the same
x=3
Answer:
x = log(40)
Step-by-step explanation:
[tex]5(2)^{x} =40[/tex]
[tex]10^{x} =40[/tex]
[tex]10^{x} =40[/tex]
x = log(40)
Which line is parallel with y = -3x + 10
Answer:
If a line is parallel with Another...
They will have the same Gradient or equal Gradient (m)
So for two parallel lines
m=m'
So the gradient of the second or other line would be Same
Now
y= -3x + 10
comparing with
y= mx + c
m = -3
So the other line would have the same gradient.
from the options provided in the comment section...
y= -3x + 12
Is your Most probable answer cos it has the same gradient
Find the surface area of a cone with volume 320pi and height 15 (hint: don't use the height in
the surface area formula.
Answer key :
Either 200 pi or 325 pi
Please help !!!
Answer:
200π
Step-by-step explanation:
Surface area of a cone = πr(r+l)
r is the radius
l is the slant height
Volume of the cone = 1/3πr²h
320π = 1/3πr²h
320 = 1/3r²(15)
320 = 5r²
r² = 320/5
r² = 64
r = 8
l² = 15² + 8²
l² = 225 + 64
l² = 289
l = 17
Get the surface area;
S = πr(r+l)
S = π8(8+17)
S = π*8*25
S = 200π
Hence the surface area of the cone is 200π
Find the distance between the two points in simplest radical form. (0,−7) and (−6,1)
Answer:
10
Step-by-step explanation:
d = √(x2 -x1)² + (y2 - y1)²
√(-6 - 0)² + [1 - (-7)]²
√(-6)² + (8)²
√(36) + (64)
√100
= 10
8 less than a number x is more than 5 times that same number.
Answer:
x < -1/2
Step-by-step explanation:
x - 8 > 5x
-8 > 5x -x
-8 > 4x
Divide through by 8
-1/2 > x or x < -1/2.
That is ofcourse if I interpreted the first part correctly.
Evaluate the equation y=2x2 - 2x + 7 for x=-3
Answer:
31
Step-by-step explanation:
y=2x^2 - 2x + 7
Let x= -3
y=2(-3)^2 - 2(-3) + 7
=2 (9) +6 +7
= 18 +6+7
= 31

1. Write and solve an inequality that represents the number of months the center could
rent games from NetGames with its $175. Explain the solution in terms of the problem.
Solution :
Given that the Centre is signing up for a rental game service online rather than buying the game.
The monthly fees and the equipment cost of the two services that is the 'Anytime games' and the 'Netgames' are attached below.
Therefore, the inequality which represent the number that the center can rent the online games from the NetGames is :
175 - 8m ≥ 99
175 - 8m - 99 ≥ 99 - 99 (Subtracting 99 from both side of the inequality)
76 - 8m ≥ 0 (Simplify)
76 - 8m -76 ≥ 0 - 76 (Subtracting 76 from both side of the inequality)
- 8m ≥ - 76 (Simplify)
8m ≥ 76 (removing the minus sign form both sides)
[tex]$\frac{8m}{8} \geq\frac{76}{8}$[/tex] (Divide each side of the inequality by 8)
m ≥ 9.5

How can you find the slope of a line from the coordinates of two points on the line?
Answer:
use the slope formula to find the slope of a line given the coordinates of two points on the line and the slope formula is m=( y2- y1)/ (x2 - x1) or the change in the y values over the change in x values.The coordinates of the point represent x1 and y1. The coordinates of the second points are x2, y2.
-6-9t+4=34 Simplify plz
Answer:
t = -4
Step-by-step explanation:
-6-9t+4=34
-9t=34+6-4
-9t=36
-t=36/9
-t = 4
t = -4
Answer:
t = -4
Step-by-step explanation:
-6-9t+4=34
Combine like terms
-9t -2 = 34
Add 2 to each side
-9t -2+2 = 34+2
-9t = 36
Divide by -9
-9t/-9 = 36/-9
t = -4

Based on records from the past several seasons the probability of the Madison Math Team winning a competition is p(win)-0.875
If they compete in 24 competitions, how many will they win?
Answer:
They will win 21 games
Step-by-step explanation:
Here, we want to get the number of possible wins
From the question, we have it that the probability that the team will win is 0.875
Now, out of the 24 games, we simply have to multiply their winning probability by the number of games
We have this as;
0.875 * 24 = 21
Hence, out of the 24, 21 will result in a win
