How do you solve the system of equations 8x-9y=158x−9y=15 and -x+4y=1−x+4y=1 by combining the equations.
Answer:
x = 3 and y = 1
Step-by-step explanation:
Give system of equations are :
8x-9y=15 ...(1)
−x+4y=1 ...(2)
Multiply equation (2) by 8.
−8x+32y=8 ..(3)
Add equation (1) and (3).
8x-9y -8x + 32y = 15+8
23y = 23
y = 1
Put the value of y in equation (2).
−x+4(1)=1
-x = -4+1
x = 3
Hence, the values of x and y are 3 and 1.

a trapezoidal prism has a volume of 1260 cm^3. the height of the prism is 18 cm while the bases of the trapezoid are 12 cm and 8cm. Sketch the prism and find the height of the trapezoidal base
Answer:
7 cmStep-by-step explanation:
Volume of the prism is the product of its base area and height
V = AHV = 1260 cm³H = 18 cmFind base area:
A = 1260/18 = 70 cm²Area of the trapezoid:
A = 1/2(b₁ + b₂)hSubstitute given values and solve for h:
70 = 1/2(12 + 8)h70 = 10hh = 70/10h = 7 cmFind area of base
Volume/Height1260/1870cm²Now
Height of trapezoid base be x
1/2(12+8)x=7020x=140x=7cmCompute the standard deviation if n = 60, p = 0.4, and the sample size is less than 10% of the population.

Please help me with this please if you don’t know don’t answer is 13 points
Answer:
x=29
Step-by-step explanation:
We know for a fact that in a square:
- All of its angles have equal measure (90 degrees)
(e.g. Measure of Angle CAT, measure of Angle CST = 90 degrees)
Now that we know the facts, let's try to find x.
Now since we know that all the angles are equivalent to 90 degrees, we can say that Measurement of Angle SCA is 90 degrees. So:
[tex]90=3x+3[/tex]
Next, we'll simply just isolate the x:
[tex]90=3x+3\\90-3=3x+3-3\\87=3x\\\frac{87=3x}{3} \\29 = x[/tex]

Simplify. [tex](3a^{2}*5a^{2})[/tex]
Answer: 8a
Step-by-step explanation:
Step-by-step explanation:
I can only think of one way to simplify this and it is by taking out the greatest common factor: a². Or by multiplying the two values together so it's only one value.
a²(3*5)
a²(15)
Or...
(3a² * 5a²)
(15a⁴)
(this one is a⁴ because a variable with a power multiplied by a variable with a power only adds the powers together)
Abha is climbing a mountain. While covering 20 yards of horizontal distance, Abha’s elevation increases by 40 yards. Consider Abha’s climb as a linear function.
A drawing shows a girl hiking. The vertical distance is forty yards. The horizontal distance is twenty yards.
What is the slope of her climb?
Answer:
The answer is 2
Step-by-step explanation:
The slope of Abha's climb is given by the equation
Slope m = 2
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be A
Now , let the point be P ( x , y )
And , the equation is given by
The horizontal distance covered by Abha x = 20 yards
The vertical distance covered by Abha y = 40 yards
Now , the slope of the point is given by the equation
Slope m = vertical distance covered by Abha / horizontal distance covered by Abha
Substituting the values in the equation , we get
Slope m of Abha's climb = y/x
Slope m of Abha's climb = 40 / 20
Slope m of Abha's climb = 2
Therefore , the slope of the line is m = 2
Hence , The slope of Abha's climb is given by the equation Slope m = 2

14=s/3 what does s equal
===============================================
Explanation:
To isolate s, we need to undo the division. We'll multiply both sides by 3
14 = s/3
3*14 = 3*(s/3)
42 = s
s = 42
-------
As a check,
14 = s/3
14 = 42/3 .... replace s with 42
14 = 14
We get the same thing on both sides, so this confirms we have the correct value of s.

5(- 3x - 2) - (x - 3) = -4(4x + 5) + 13
Answer:
0
Step-by-step explanation:
Let's solve your equation step-by-step.
5(−3x−2)−(x−3)=−4(4x+5)+13
Step 1: Simplify both sides of the equation.
5(−3x−2)−(x−3)=−4(4x+5)+13
5(−3x−2)+−1(x−3)=−4(4x+5)+13(Distribute the Negative Sign)
5(−3x−2)+−1x+(−1)(−3)=−4(4x+5)+13
5(−3x−2)+−x+3=−4(4x+5)+13
(5)(−3x)+(5)(−2)+−x+3=(−4)(4x)+(−4)(5)+13(Distribute)
−15x+−10+−x+3=−16x+−20+13
(−15x+−x)+(−10+3)=(−16x)+(−20+13)(Combine Like Terms)
−16x+−7=−16x+−7
−16x−7=−16x−7
Step 2: Add 16x to both sides.
−16x−7+16x=−16x−7+16x
−7=−7
Step 3: Add 7 to both sides.
−7+7=−7+7

13x = 3(X-20) How to solve this algebra equation?
Answer:
x = -6
Step-by-step explanation:
13x = 3(x - 20) {Use distributive method:a(b+c)=(a*b) + (a*c)
13x = 3*x - 3*20
13x = 3x - 60 {Subtract '3x' from both sides}
13x -3x = -60
10x = -60 {Divide both sides by 10}
x= -60/10
x = -6

Answer:
c
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
Set 1
sum = (2 × 27) + (2 × 28) + (3 × 29) + (2 × 30) + (1 × 33)
= 54 + 56 + 87 + 60 + 33 = 290
The count is 10 ( number of dots ), then
mean = [tex]\frac{290}{10}[/tex] = 29
Set 2
sum = (4 × 24) + (4 × 25) + (2 × 27)
= 96 + 100 + 54 = 250
The count is 10 ( number of dots ), then
mean = [tex]\frac{250}{10}[/tex] = 25
