Answer:
4,320
Step-by-step explanation:
7 is closer to 10 then 0. 4,310 + 10 = 4,320
The first given equation is:
4x + 3y = 6
which can be rewritten as:
2(2x) + 3y = 6 .............> equation I
The second given equation is:
2x + 2y = 5
which can be rewritten as:
2x = 5 - 2y ........> equation II
Substitute with equation II in equation I to get the value of y as follows:
2(5-2y) + 3y = 6
10 - 4y + 3y = 6
-y = 6-10 = -4
y = 4
Substitute with the y in equation II to get x as follows:
2x = 5 - 2y
2x = 5 - 2(4)
2x = 5 - 8 = -3
x = -3/2
From the above calculations:
x = -3/2
y = 4
200 centimeters. Because there are 100 centimeters in a meter. <span />

Answer:
$43 and
$17
Step-by-step explanation:
Let the amount James have be A and that of jada be B
Given
James and jada have $60 together
That’s
A + B = 60
And james A has $9 more than twice jada’s amount
That’s
A = 9 + 2B
We now have two equations
1. A + B = 60 and
2. A = 9 + 2B
Now put 9 + 2B as A in equation one
A + B = 60
9 +2B + B = 60
9 + 3B = 60
Subtract 9 from both sides
9 - 9 + 3B = 60 - 9
3B = 51
Divide both sides by 3
3B/3 = 51/3
B = 17
Jada has $17
Recall
A = 9 + 2B
And B = 17
Therefore
A = 9 + 2 x 17
A = 9 + 34
A = 43
James has $43
Therefore, James has $43 while jada has $17
