4x - 2 + 30 = 68
4x + 28 = 68
4x = 40
x = 10
9b)
y = 180 -68
y= 112
Answer:
Neither of them has partitioned the values correctly. The answer to the sum 3568 × 39610 =141 328 480.
They tried the partition method but did not partitioned it correctly.
3568 = 3000+500+60+8
39610 = 30000+9000+600+10
Now multiply each value of 3568 with the values of 39610. Like:
3000 * 30000
3000 * 9000
3000 * 600
3000 * 8
and so on....
Step-by-step explanation:
15 pounds / 35 sandwiches ~ 0.43 pounds ham per sandwich
The flight is in the shape of a parabola with a vertex 5 feet above the water and 1/2 * 33 = 16.5 feet horizontally from the point of leaving the water
y = a(x - h)^2 + k
where (h,k) is the vertex of the parabola and here it is (5 , 16.5), so we have the function:-
y = a(x - 16.5)^2 + 5
when x = 0 y = 0 so
0 = a(-16.5)^2 + 5
which gives a = -0.018365
So our function for the flight path is
y = -0.018365(x - 16.5)^2 + 5 Answer
Answer:
y = -9
Step-by-step explanation:
divide by 5 first
y + 2 = -7
-2
y = -9
