Either way light travels 2.99 times 10^8 scientifically speaking but given the facts above it is 3 times 10^8
Step-by-step explanation:
2x = x + 11
x = 11
Answer: 13=5x-2
Step-by-step explanation:
This means that two is reduced from five times the number x.
Answer:
45hours
Step-by-step explanation:
Given
Mary month earnings to be R(x)=13x+155
Josies monthly earning is given as Q(x)=9x+335
If Josie and Mary work to earn the same salary, then R(x) = Q(x)
13x+155 = 9x+335
subtract 155 from both sides
13x+155-155 = 9x+335-155
13x = 9x+180
subtract 9x from both sides
13x-9x = 9x+180-9x
4x = 180
x = 180/4
x = 45
Since x equals the number of hours worked by Josie and Mary, this means that Josie and Mary must work for 45hours to earn the same salary
Answer:
y=2x-8
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept value.
It says the slope is 2, so we know that y = 2x+b. To find b, plug in a point given. We are given (9,10), so plug that into the equation, where y = 10 and x = 9. 10=2(9)+b, solve for b.
b equals -8, so the answer is y=2x-8.
