For a you need to do (10 times 13) plus (10 times 7) because there's two boxes one is shaded.
For b you need to do (7.5 times 20) plus (2.5 times 20)
X varies directly with y means x=ky
k is the constant of variation
given when x=32 and y=8
32=8k
divide by 8
4=k
so
x=4y
when y=44
x=4(44)
x=176
x=176 when y=44
Answer:
1.3*10^-3
Step-by-step explanation:
When using scientific notation, if you are moving to the left it is a positive exponent. If you are moving to the right it is a negative exponent. since we moved the decimal point to the right, the exponent will be negative.
36 ways to roll 2 dice
There are 10 ways to roll 1 thru 5…
Thus there are 26 / 36 ways to roll >5 (13/18)
Answer:
Equation: y = 2x + 7
Step-by-step explanation:
If the line is parallel to the line resembling the equation y = 2x - 4, it would mean that the line would have a similar slope, leading to part of the equation:
y = 2x
Now substitute the x-coordinate -2 and y-coordinate 3 into the equation * (derived from (-2, 3) ):
3 = 2(-2)
Now simplify either side:
3 = -4
For 3 to equal -4, you would have to add 7:
3 = -4 + 7 = 3
This means the final equation is:
y = 2x + 7
