question: solve the solution using substitution.
Answer:
x = -3
y = -8
Step-by-step explanation:
2y = x - 13
3x = y - 1; let y = 3x + 1
substitute to solve for 'x':
2(3x + 1) = x - 13
6x + 2 = x - 13
5x + 2 = -13
5x = -15
x = -3
solve for 'y':
3(-3) = y - 1
-9 = y - 1
-8 = y
Answer:
(-3,-8)
Step-by-step explanation:
Get one of the variables by themself.
3x = y-1
y = 3x+1
Plug that equation into the other one
2(3x+1) = x-13
Distribute the 2 to 3x+1
6x+2 = x-13
Combine like terms
6x+2 = x-13
-x -x
5x+2 = x-13
-2 -2
5x = -15
Divide by 5 on both sides
5x = -15
÷5 ÷5
x = -3
Find y
3(-3) = y-1
-9 = y-1
+1 +1
y = -8

Can someone help please
Answer:
x ≈ 7.7
Step-by-step explanation:
Using Pythagoras' identity on the right triangle on the right side
let the third side be y , then
y² + 4² = 10²
y² + 16 = 100 ( subtract 16 from both sides )
y² = 84
Using Pythagoras' identity on the right triangle on the left side
x² + 5² = y²
x² + 25 = 84 ( subtract 25 from both sides )
x² = 59 ( take the square root of both sides )
x = [tex]\sqrt{59}[/tex] ≈ 7.7 ( to the nearest tenth )

Answer:
1 : 6
Step-by-step explanation:
From the question given above, the following data were obtained:
Radius (r) = 10 cm
Height (h) = 15 cm
Ratio of TSA and CSA =?
Next, we shall determine the total surface area (TSA) of the cylinder. This can be obtained as follow:
Radius (r) = 10 cm
Height (h) = 15 cm
Pi (π) = 3.14
Total surface area (TSA) of the cylinder =?
TSA = 2πr(r + H)
TSA = 2 × 3.14 × (10 + 15)
TSA = 6.28 × 25
TSA = 157 cm²
Next, we shall determine the curve surface area (CSA) of the cylinder. This can be obtained as follow:
Radius (r) = 10 cm
Height (h) = 15 cm
Pi (π) = 3.14
Curve surface area (CSA) of cylinder =?
CSA = 2πrh
CSA = 2 × 3.14 × 10 × 15
CSA = 942 cm²
Finally, we shall determine the ratio of the total surface area (TSA) and curve surface area (CSA) of the cylinder. This can be obtained as follow:
TSA = 157 cm²
CSA = 942 cm²
Ratio of TSA and CSA =?
TSA : CSA = 157 / 942
TSA : CSA = 1 / 6
TSA : CSA = 1 : 6
Thus, the ratio of the total surface area (TSA) and curve surface area (CSA) of the cylinder is 1 : 6

A pipe can fill a tank in 3 hours. A second pipe can fill the tank in 5 hours.
How long will it take to fill the tank with both pipes running at the same time?
Answer:
15 hours
Step-by-step explanation:
3: 3, 6, 9, 12, 15
5: 5, 10, 15, 20
15 is the lcm of 3 and 5
Answer:
15 hrs
Step-by-step explanation:
Time for One pipe = 3 hrs
Amount of tank it can fill in 1 hr = 1/3
Time for Second pipe = 5 hrs
Amount of tank it can fill in 1 hr = 1/5
Tank they can fill together in 1 hr = 1/3 x 1/5= 1/15
Time it takes to fill full tank = 15/1

1) Expand and simplify the following:
a)3(x squared plus 3x cubed - 2)
Answer:
3x³ + x² - 2
Step-by-step explanation:
a) 3(x squared plus 3x cubed - 2)
x squared = x²
3x cubed = 3x³
3(x squared plus 3x cubed - 2)
= 3(x² + 3x³ - 2)
= 3x² + 9x³ - 6
Rearrange according to power
= 9x³ + 3x² - 6
When the expression is divided by 3, it is equivalent to
3x³ + x² - 2

Given right triangle ABC with altitude BD drawn from vertex B to hypotenuse AC, find the lengths of AD, BD, and CD.
Keep as improper fraction
Answer:
AD = 3
BD = 10
CD = 17
Step-by-step explanation:
The requires side lengths are:
[tex]AD = \frac{49}{25}[/tex]
[tex]BD = \frac{168}{25}[/tex]
[tex]CD = \frac{576}{25}[/tex]
Considering triangle BDC, we have:
[tex]BC^2 = BD^2 +CD^2[/tex]
This gives
[tex]24^2 = BD^2 +(25 - AD)^2[/tex]
[tex]576 = BD^2 +(25 - AD)^2[/tex] --------- (1)
Considering triangle ABD, we have:
[tex]7^2 = BD^2 + AD^2[/tex]
[tex]49 = BD^2 + AD^2[/tex] ---- (2)
Subtract (2) from (1)
[tex]576 - 49 = BD^2 -BD^2 +(25 - AD)^2 - AD^2[/tex]
[tex]527 = (25 - AD)^2 - AD^2[/tex]
Expand
[tex]527 = 625 - 50AD + AD^2 - AD^2[/tex]
[tex]527 = 625 - 50AD[/tex]
Collect like terms
[tex]50AD = 625 - 527[/tex]
[tex]50AD = 98[/tex]
Divide both sides by 50
[tex]AD = \frac{98}{50}[/tex]
Reduce fraction
[tex]AD = \frac{49}{25}[/tex]
Recall that:
[tex]49 = BD^2 + AD^2[/tex]
So, we have:
[tex]49 = BD^2 + (49/25)^2[/tex]
[tex]49 = BD^2 + 2401/625[/tex]
Collect like terms
[tex]BD^2 = 49 - 2401/625[/tex]
Take LCM
[tex]BD^2 = \frac{625 *49 - 2401}{625 }[/tex]
[tex]BD^2 = \frac{28224}{625}[/tex]
Take the square roots of both sides
[tex]BD = \frac{168}{25}[/tex]
Also, we have:
[tex]CD = 25 - AD[/tex]
This gives
[tex]CD = 25 - \frac{49}{25}[/tex]
Take LCM
[tex]CD = \frac{625 - 49}{25}[/tex]
[tex]CD = \frac{576}{25}[/tex]
Hence, the requires side lengths are:
[tex]AD = \frac{49}{25}[/tex]
[tex]BD = \frac{168}{25}[/tex]
[tex]CD = \frac{576}{25}[/tex]
