Answer: Red copper = $0.12 per meter
Yellow copper = $0.22 per meter
Step-by-step explanation:
Since Red copper costs $0.90 for 7.6m, the cost of 1m of red copper will be:
= $0.90/7.6
= $0.12
Since yellow copper costs $1.12 5.2m, the cost of 1m of yellow copper will be:
= $1.12 / 5.2
= $0.22 per meter

If the buses run on schedule, when is the next time a red line and a blue line bus will leave together? Show your work.
Answer:
So the next time they will leave together is 4:24 pm
Step-by-step explanation:
Since both the buses left at 4 pm and red line bus leaves every 6minutes and blue line bus leaves every 8 minutes they next time they leave together can be found by taking the L.C. M of 6 and 8.
The L.C. M is found by multiplying all the factors and chosing one which common in both numbers.
Factors of 6 = 2*3
Factors of 8= 2*2*2
In these numbers 2 is common in both.The rest of the numbers( 2*2*3 )are multiplied with the the common 2 to get the L.C.M
L.C.M= 2*2*2*3= 24 minutes
So the next time they will leave together is 4:24 pm
7x + 2y - 3 = 0 in slope intercept form.
Answer:
y=(-7/2)x+3
Step-by-step explanation:
7x+2y-3=0
7x+2y=3
2y=-7x+3
y=(-7/2)x+3
Answer:
y = - [tex]\frac{7}{2}[/tex] x + [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
7x + 2y - 3 = 0 ( subtract 7x - 3 from both sides )
2y = - 7x + 3 ( divide each term by 2 )
y = - [tex]\frac{7}{2}[/tex] x + [tex]\frac{3}{2}[/tex] ← in slope- intercept form

The first term of an arithmetic sequence is -3 and the fifteenth term is 53. What is the common difference of the sequence?
A) 14/13
B) 25/7
C) 4
Answer:
C) 4Step-by-step explanation:
The nth term of arithmetic sequence is [tex]a_n=a_1+d(n-1)[/tex]
So:
[tex]a_{15}=a_1+d(15-1)\\\\53=-3+14d\\\\56=14d\\\\d=\dfrac{56}{14}=4[/tex]

The temperature drops to a rate of five degrees per hour. Be d the number of degrees that lowers the temperature. Be the number of hours you spend. What is the dependent variable?
Answer:
d, the number of degrees that the temperature was lowered by
Step-by-step explanation:
The dependent variable in this scenario would be d, the number of degrees that the temperature was lowered by. This is because the value of this variable depends on the actual amount of hours that have passed by. Therefore, depending on the number of hours, the value of d could be completely different. The variable h for the number of hours does not depend on any other variable in the equation and has its own value, but since d depends on h then it would be the dependent variable in this scenario.

Find the value of x: 3x−7=8x+23
Answer: x=6
Step-by-step explanation:
Answer:
x = -6
Step-by-step explanation:
Subtract 3x from both sides to get -7=5x+23.
Subtract 23 from both sides to get -30=5x.
Divide 5 from both sides.
x = -6.

Answer:
d) [tex](9*3/4)+y[/tex]
Step-by-step explanation:
b) [tex]9+y*(3/4)[/tex]
This expression is not equivalent, as the original expression, [tex]y+9*\frac{3}{4}[/tex] , has 9 multiplied to [tex]\frac{3}{4}[/tex] instead of y. You can interchange values like this when it comes to addition, but not multiplication.
c) [tex](y+9)(3/4)[/tex]
This expression is also not equivalent. After opening up the parentheses, it would again result in y being multiplied to [tex]\frac{3}{4}[/tex].
[tex](y+9)(3/4)\\= y(3/4)+9(3/4)[/tex]
d) [tex](9*3/4)+y[/tex]
This expression is equivalent, as 9 and [tex]\frac{3}{4}[/tex] are still being multiplied together and y is added to the product. We can actually rearrange this to look like the original expression:
[tex](9*3/4)+y\\=y+(9*3/4)\\=y+(9*\frac{3}{4} )\\=y+9*\frac{3}{4}[/tex]
I hope this helps!

PLEASE HELPPP!!!
Explain your thinking!!
don’t answer just for points or i’ll report you.
Answer:
Negative
Step-by-step explanation:
On the line, we see that a = 0.5 and b is after -1. a + b will be negative because anything after -1 added to .5 will be negative.
Example:
-1 + .5 = -.5
-2 + .5 = -1.5
-3 + .5 = -2.5
Answer: Negative
Step-by-step explanation: the b we can see is far away from -1 that means its around - 2 and if we were to add 0.5 and - 2 we would get -1.5
