Answer:
c) Circle 5 and 20, 10 and 40, 15 and 60, 20 and 80, and 25 and 100. When you multiply the top by 4, they all equal the bottom values.
d) The bottom compares to the top terms because you can divide them by 4 and they'll equal the top terms
Can someone help me figure out how to do this?
If 5x + 4y= 13 and 4x + 5y = 14, find the value of (x - y).
Answer:
x - y = - 1
Step-by-step explanation:
Given the 2 equations
5x + 4y = 13 → (1)
4x + 5y = 14 → (2)
Subtract (2) from (1) term by term , that is
(5x - 4x) + (4y - 5y) = 13 - 14
x - y = - 1
Answer:
x = 1
y = 2
x - y = -1
Step-by-step explanation:
5x + 4y= 13, then 4y = 13 - 5x, then y = (13 - 5x)/4
4x + 5y = 14
substitute for y:
4x + 5(13 - 5x)/4 = 14
simplifying:
4x + (65 - 25x)/4 = 14
4x + 16.25 -6.25x = 14
-2.25x = -2.25
x = 1
y = (13 - 5)/4 = 2

CAN SOMEONE PLEASE GIVE ME THE ANSWER TO QUESTION 6? PLS ILY
Answer:
12.5
Step-by-step explanation:
We want to find 1/8 of 100 so we would write it as 100÷8 to get 12.5
Now we know that 12.5 is equivalent to 1/8 but let's double check.
12.5×8 is 100
1/8 ×8 is 8/8
100=8/8

Solve the system of equations.
12x - 5y = –20
y=x+4
2 =
Y=
Answer:
Solution :
{x,y} = {0/14261512,4}
Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = x + 4
// Plug this in for variable y in equation [1]
[1] 12x - 5•(x +4) = -20
[1] 7x = 0
// Solve equation [1] for the variable x
[1] 7x = 0
[1] x = 0
// By now we know this much :
x = 0
y = x+4
// Use the x value to solve for y
y = (-0/14261512)+4 = 4

Answer:
45Step-by-step explanation:
Well, it is not 90 degrees, as it is not a right angle.
It cannot be 180 degrees as that would be a straight line and a triangle's whole angle measure is 180 degrees.
It is an acute angle, and appears to be half of 90 degrees, so I would have to say 45 degrees.
Not enough information is false because you can infer that it is 45 degrees by looking at it.
Hope that helps!

A mountain climber ascends a mountain to its peak. The peak is 14,090 ft above sea level. The climber then descends 490 ft to meet a fellow climber. Find the climber’s elevation above sea level after meeting the other climber.
13,600 ft
14,580 ft
–13,600 ft
9,190 ft
Answer:
13,600 feet above sea level
Step-by-step explanation:
The climber was at 14,090 feet above sea level, and then they went 490 feet closer to sea level to meet the other climber. Since they’re moving closer to sea level and you want to know how far *above* sea level they are, subtract 490 from 14,090. 14,090-490=13,600 feet above sea level

Steve invests $1,800 in an account that earns 3.7% annual interest, compounded continuously. What is the value of the account after 10 years? Round your answer to the nearest dollar. A. about $2,466 B. about $2,589 C. about $2,601 D. about $2,606
Answer:
B. about $2,589
Step-by-step explanation:
Given data
P=$1,800
R= 3.7%
T=10years
The expression for the compound interest is given as
A= P(1+r)^t
substitute
A= 1800(1+0.037)^10
A= 1800(1.037)^10
A=1800*1.43809495884
A=$2588.570
Hence the answer is B. about $2,589
