X=Y-7
4X+2Y=62
4(Y-7)+2Y=62
4Y-28+2Y=62
6Y=62+28
6Y=90
Y=90/6
Y=15
Larger number^
X=15-7=8
Smaller number^
PROOF:
4*8+2*15=62
32+30=62
62=62
Hope this helps.
This is actually a trick question if you were to take this question head on. Say for instance you are cutting all the pieces from the same sheet of metal, the equation would NOT be 8 times 5 equals 40 minutes, but rather 7 times 5 equals 35 minutes. this is because on the 7th cut, it takes that from 6 sheets of metal to 8 because you get 2 from that cut. Take for instence, a Hersheys candy bar. It is 3 bars thick, but it only takes 2 breaks to sever the 3 strips. So, that being said, sam will make 7 cuts and those 7 cuts will make a times of 35 minutes.
Answer:
13/14 is greater
Step-by-step explanation:
Find the lcm for both:
<u>9 x 7 </u> = <u>63</u>
10 x 7 70
<u>13 x 5 </u> = <u>65</u>
14 x 5 70
so therefore 13/14 is greater since it has a greater value when finding the lcm
Answer:
Step-by-step explanation:
In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).
Answer:
Step-by-step explanation:
First, add two to both sides to get 
There are two ways to solve this from here
- Think about what power you would have to raise 9 to to get to 27.
= 3 and 
. So, multiplying the powers (because it is a power to a power) you get 
. This means that 
or x = . - Take the log of both sides.
This gives us
