Answer:
x=3 and y=2
Step-by-step explanation:
9x - 4y= 19
4x + 4y= 20
add both equations;
13x = 39
x= 3
using 4x + 4y= 20;
4(3) +4y=20
12+4y=20
4y= 20-12=8
y=8/4=2
x+3y=10 what is the slope of the line
Answer:
-1/3 is the slope of the line
Step-by-step explanation:
Answer:
[tex]-\frac{1}{3}[/tex]
Step-by-step explanation:
y = mx + b
m is the slope and b is the y-intercept.
Subtract x from both sides of the equation.
x - x + 3y = 10 - x
3y = 10 - x
Divide each term by 3.
[tex]\frac{3y}3y} = \frac{10}{3} + \frac{-x}{3}[/tex]
[tex]y = \frac{-x}{3} + \frac{10}{3}[/tex]
Rewrite in slope intercept form.
[tex]y = -\frac{1}{3}x + \frac{10}{3}[/tex]
What is the area of this triangle?
Answer:
The area of the triangle is 24 inches.
Step-by-step explanation:
First you multiply 8 by 6.
8 * 6 = 48
Next you divide by 2 because a triangle is half of a square.
48 ÷ 2 = 24
So, the answer is 24.
Hope this helps! :)
The area of triangle with base 6 inches and height 8 inches is 24in² .
Given, Right angled triangle .
Area of triangle = [tex]\frac{1}{2} \times b \times h[/tex]
Here,
b = base of triangle
h = height of triangle
Substitute the values,
Area of triangle = [tex]\frac{1}{2} \times b \times h[/tex]
[tex]= \frac{1}{2} \times 6 \times 8\\ = 3 \times 8\\= 24in^2[/tex]

What is the value of x of the acute angles of a right triangle measure 8x and 12x?
A.2
B. 4.5
C. 7
D. 9.5
Answer:
B. 4.5
Step-by-step explanation:
The sum of all interior angles of a triangle is 180 degrees
Since we know it is a right triangle, there is one angle that is 90 degrees
The acute angles are given as 8x and 12x
Add them up and isolate x to find the value of it
8x + 12x + 90 = 180 1. Add like terms
20x + 90 = 180 2. Subtract by 90 on both sides
20x = 90 3. Divide by 20 on both sides
x = 4.5

i really need help with this 6th grade work due today
5
Step-by-step explanation:
Length (L) = u
Breadth (b) = 6 mi
Perimeter (P) = 22 miles
Now we know
P = 2 (L+ b)
22 = 2 ( u + 6)
11 = u + 6
11 - 6 = u
u = 5
Answer:
u = 5
Step-by-step explanation:
The perimeter of a rectangle is all the sides added up.
The oppisite sides are parralel.
So the side across from 6 is all 6
6 + 6 = 12
The perimeter is 22 so you do
22 - 12 = 10
So 'u' equals 5 because you have to divide the number 10 by 2.

The scale of a room in a blueprint is 5 in.: 9 ft. A wall in the same blueprint is 30 in. Complete the table.
Blueprint length (in.) 5
10
15
20
25
30
Actual length (ft)
9
How long is the actual wall?
The actual wall is
feet long
A window in the room has an actual width of 4.5 feet. Find the width of the window in the blueprint.
The width of the window in the blueprint is
in.
Answer:
54 feets
2.5 inches
Step-by-step explanation:
Given that:
Scale model:
5 in : 9ft
If 5 in = 9 ft
Hence, 1 in on the blue print equals
5 in = 9 ft
1 in = x
Cross multiply
5x = 9
x = 9/5 feets
Hence, 1 inches on the blueprint equals 9/5 feets actual
Blueprint length (in.) ___ Actual length (ft)
5 _________ 9
10 ________ 18
15 ________ 27
20 _______ 36
25 _______ 45
30 _______ 54
Hence ;
5 * 9/5 = 9 feets
10 * 9/5 = 18 feets
15 * 9/5 = 27 feets
20 * 9/5 = 36 feets
25 * 9/5 = 45 feets
30 * 9/5 = 54 feets
Window with actual width of 4.5 feets
Width of window in blue print :
Actual width ÷ 9/5
Actual width = 4.5 = 4 1/2 = 9/2
9/2 * 5 /9
= 5 /2
= 2 1/2 inches = 2.5 inches

Given f(x) = -x + 2, find f(-5).
Answer:
7
Step-by-step explanation:
We have the expression -x + 2 and are asked to solve if x = -5.
Since we know the value of x, we need to replace x with the amount it is.
-x + 2 if x = -5.
-(-5) + 2
Negative cancels a negative.
5 + 2

Nancy started the year with $425 in the bank and is saving $25 each week. Sam started the year with $705 but is spending S15 a week. Write a system of equations that model the following situation.
Define cach variables with a "Let" statement, write two equations, and solve completely.
Answer:
Step-by-step explanation:
Let x equal number of weeks and y equal money in the bank.
Nancy, y=425+25x
Sam, y=705-15x
The system of equations:
Nancy: [tex]y=\$425+\$25x[/tex]
Sam : [tex]y=\$705-\$15x[/tex]
Given:
Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Amount in Sam's bank = $705
Amount spend by Sam each week = $15
To find:
The system of equations describing the given models.
Solution
1) Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Let the number of weeks Nancy saving her money be 'x'.
Let the total amount of money in Nancy's bank after x weeks be 'y'.
[tex]y=\$425+\$25\times x\\y=\$425+\$25x[/tex]
The equation for Nancy:
[tex]y=\$425+\$25x[/tex]
2)
Amount in Sam's bank = $705
Amount spend by Sam each week = $15
Let the number of weeks Sam spending his money be 'x'
Let the total amount of money left in Sam's bank after x weeks ='y'
[tex]y=\$705-\$15\times x\\y=\$705-\$15x[/tex]
The equation for Sam:
[tex]y=\$705-\$15x[/tex]
