Perimeter is 70
area is 229
We can create a system of equations with the information we know.
J = 4L
J + L - 6 = 64
The first equation is pretty self-explanatory. Jack is 4 times as old as Lucy. The second equation is just adding their ages together. We subtract 6 because the sum of their ages was 64 three years ago. Three years ago, both Jack and Lucy were 3 years younger (total of 6).
Substitute 4L in for J in the second equation and solve.
4L + L - 6 = 64
5L = 70
L = 14
If Lucy is 14, then Jack is 14*4 = 56.
The same length, if something is congruent it means they’re the same
Answer:
0.003, 5/1000, 9/1000
Step-by-step explanation:
0.003 is thousandths.
5/1000 is thousandths.
9/1000 is thousandths.
I converted them to fractions.
5/1000 is already a fraction
Same for 9/1000
0.003=3/1000
So 3/1000, 5/1000, 9/1000
Answer:
Step-by-step explanation:
According to the given table, the variables have a linear relation, because there's a constant change involved.
Notice that p-variable increases by one unit, while q-variable increases by 10 units. That means the ratio of change is
Then, we use one pair of elements, like (3,30), and the point-slope formula to find the equations.
Therfore, the equation that represents the table is
