Answer:
x = 10 and y = 8
Step-by-step explanation:
100=10x
100= 10y+20
For x, for first equation, we simply solve for x.
10x = 100 => x=100/10
Therefore, x =10
For y, for second equation, simply solve for y.
100= 10y+20 => 10y = 100-20
10y = 80 => y = 8
Answer: D. 120.25
Explanation: Multiply 6.5 and 18.5
10 blocks = 6 min
30 blocks = 18 min
You can answer this because you know that 10 x 3 is 30, so if if the number of blocks tripled then the amount of time should triple as well because he's running at the same rate.
Answer:
B as we start with X intercept =0
Step-by-step explanation:
x= 10 x 6 = 60
(v= 1/6x = 6x x 10y) x= 60v
y=10
When x=0 then y = 0 when x= 10 we have 10 minutes each count
So the graph will go up by 10 to 60 on the x axis.
value of nickle=6 and units of 10 nickles have value of 60
But this is a measure of time using nickles for x.
and measure of quarters can then show a pattern of zero each time. y=mc+x = 0 when y=0 = y=1x0+0 when x =6 and y=0
Answer:
3x - 27 = 51
x equals 26
Step-by-step explanation:
3(dollars) times x(number of shirts sold). Then you subtract the amount she spent on supplies($27) and you get 51, the total profits she made.
