Answer: see below
Step-by-step explanation:
Set up two equations, one for each scenario
88w + 21b = 5840
84w + 82b = 9044
Use one equation and isolate one of the variables. We'll isolate w in the first equation.
88w + 21b = 5840
88w = 5840 - 21b
w = (5840 - 21b)/88
Then substitute that into the second equation.
84w + 82b = 9044
42w + 41b = 4522 (simplified)
42((5840 - 21b)/88) + 41b = 4522
21((5840 - 21b)/44) + 41b = 4522 (simplified)
(122640 - 441b)/44 + 1804b/44 = 4522
(122640 - 441b + 1804b)/44 = 4522
122640 + 1363b = 198968
1363b = 76328
b = 56
Now that we know belts are $56, we can substitute that back into any equation and solve for w.
w = (5840 - 21b)/88
w = (5840 - 21(56))/88
w = (5840 - 1176)/88
w = 4664/88
w = 53

Step-by-step explanation:
A copy machine can print 340 color copies every 8 minutes. So how many copies can be made 28 minutes
Answer:
1190
Step-by-step explanation:
We have the ratio: 8:340 which means that 340 copies are printed in 8 minutes
We want to find out how many color copies are printed in 1 minute so we divide by 8
so our new ratio is now 1:42.5
We now multiply this ratio by 28 to find out how many are printed in 28 minutes
28:1190
our answer is 1190 copies
The parallelogram shown represents a map of the boundaries of a natural preserve. Walking trails run from points A to C and from points B to D. The measurements shown represent miles. Parallelogram A B C D is shown. Diagonals are drawn from point A to point C and from point D to point B and intersect at point E. The length of D E is y + 2, the length of E B is 3 y minus 4, and the length of E C is 2 y minus 3. What is the sum of the lengths of the two trails? 6 miles 12 miles 16 miles 36 miles
Answer:
[tex]16\ \text{miles}[/tex]
Step-by-step explanation:
In a parallelogram the diagnols bisect each other. So,
[tex]DE=EB\\\Rightarrow y+2=3y-4\\\Rightarrow 4+2=3y-y\\\Rightarrow 6=2y\\\Rightarrow y=\dfrac{6}{2}\\\Rightarrow y=3[/tex]
[tex]DE=y+2\\\Rightarrow DE=3+2\\\Rightarrow DE=5[/tex]
[tex]BD=2DE\\\Rightarrow BD=2\times 5\\\Rightarrow BD=10[/tex]
[tex]EC=2y-3\\\Rightarrow EC=2\times 3-3\\\Rightarrow EC=3[/tex]
[tex]AC=2EC\\\Rightarrow AC=2\times 3\\\Rightarrow AC=6[/tex]
The sum of the diagonals is [tex]BD+AC=10+6=16\ \text{miles}[/tex]
The sum of the lengths of the two trails is [tex]16\ \text{miles}[/tex].
Answer:
16 Miles

Answer:
how we go answer it
Step-by-step explanation:
Solve the following system algebraically, for values a, b, and c.
2a + b + c = 17
1/2c = 5
a-b=5
Answer:
a= 4
b= -1
c= 10
Step-by-step explanation:
First we start by multiplying both sides of 1/2c = 5 by 2.
c = 10
Add b to both sides of the last equation to make it a=b+5
knowing these two things, we can plug them into the first equation like this:
2(b+5) + b + 10 = 17
then you solve for b:
distribute the 2
2b + 10 + b + 10 = 17
combine like terms
3b + 20 = 17
subtract 20 from each side
3b = -3
divide by 3
b = -1
then you can plug that into the last equation again so a - (-1) =5
Subtracting a negative is the same as adding so its a + 1 = 5 or a = 4

7. Use substitution. What is the
solution of the system of
equations?
y = -4x + 11
8x + 2y = 14
A. X = 6, y = 7
B. x = 6, y = -7
C. Infinitely many solutions
D. No solution
PLEASE HELP AND PLEASE LOOK AT THE OTHER QUESTIONS I ASKED
Answer:
No solution, D
Step-by-step explanation:
If you rewrite the second one to be the y=mx+b form then you get
8x-14= -2y
Divide by -2 and get
-4x+7=y
Because the slopes are the same the lines will never intersect which means there is no solution

F(x)=-x^3+24x^2-179x+495 determine the
Average rate of change of f(x) between x=2 and x=5
Answer:
The average rate of change is -75
Step-by-step explanation:
The Average Rate of Change (ARC)
It's a measure of how much the function changed per unit, over a given interval.
Given a function F(x) and an interval between x=a and x=b, the average rate of change is:
[tex]\displaystyle A=\frac{F(b)-F(a)}{b-a}[/tex]
The function is:
[tex]F(x)=-x^3+24x^2-179x+495[/tex]
and it's required to find the ARC between x=2 and x=5.
Calculate F(2) and F(5):
[tex]F(2)=-2^3+24*2^2-179*2+495=225[/tex]
[tex]F(5)=-5^3+24*5^2-179*5+495=75[/tex]
The ARC is:
[tex]\displaystyle A=\frac{75-225}{5-3}=\frac{-150}{2}=-75[/tex]
The average rate of change is -75

Sam has to pay a 15% tax on a boat that cost him $500. He believes he can determine the tax he owes using the calculation: 15 x 5
Answer:
$75
Step-by-step explanation:
Cost = $500
Sam has to pay a 15% tax
To compute his tax, we use the step outlined bellow
tax= 15/100*500
tax= 0.15*500
tax=$75
Hence his tax is $75

Solve:
5
Answer:
c² = 34
Explanation:
Pythagorean Theorem: a² + b² = c²
Insert 3 and 5 into the equation3² + 5² = c²
Simplify3² = 9
5² = 25
9 + 25 = 34
34 = c²
- PNW
______________________________
1.) To find c, you must fill in the formula:Formula: [tex]a^2+b^2=c^2[/tex][tex]a^2=3^2[/tex][tex]b^2=5^2[/tex]- When finding c, it doesn't matter what you put for a or b. So if you want to make a = 5, and b = 3, it wouldn't make any difference.
2.) Find the powers of a and b:[tex]3^2=9[/tex][tex]5^2=25[/tex]3.) Add a and b together:[tex]9+25=34[/tex]______________________________

Step-by-step explanation:
please help me please will give its about negative numbers
Answer:
D. x>-3
Step-by-step explanation:
Since the dot on -3 is not shaded in we know it is not ≤ or ≥ so option A and C are eliminated.
Remember if the arrow is pointing to the left (<-----) Then it is Less-than which is <.
If the arrow is pointing to the right (----->) Then it is Greater-than which is >.
Since the arrow is pointing right the answer will be x>-3 which is D

Interesting question. Thanks for posting.
The small triangle has the height as the missing side.
Part One: Givens
a = 144
b = height = ?
c = 240
a^2 + b^2 = c^2
144^2 + b^2 = 240^2
20736 + b^2 = 57600 Subtract 20736 from both sides
b^2 = 57600 - 20736
b^2 = 36864
√b^2 = √36864
b = 192
Solve for x
The relationship between the height (b) and 144 and x is
b^2 = 144 * x
36864 = 144x Divide by 144
x = 256

x=3y-1
3x+4y=10
Answer:
y=1, x=2
Step-by-step explanation:
so first solve for y. plus x=3y-1 into the other equation.
so 3(3y-1)+4y=10.
Simplify
9y-3+4y=10 Add 3 to both sides
9y+4y=13 Add
13y=13 . Divide 13 from both sides
y=1
Plug 1 into the first equation.

HELP FAST I'LL MARK YOU BRAINLIEST
Answer:
y = -2x + 12
Step-by-step explanation:
Step 1: find the slope
y = 1/2x + 5
The equation of the line is
y = mx + c
m - slope
m = 1/2
Note : if two lines are perpendicular to the other, both lines are negative reciprocal of each other
m = -2
Step 2 : using a point slope form
y - y1 = m( x - x1)
( 2 , 5)
x1 = 2
y1 = 5
y - 2 = -2( x - 5)
y - 2 = -2x + 10
y = -2x + 10 + 2
y = -2x + 12
The equation of the line is
y = -2x + 12
