Answer:
Step-by-step explanation:
1/4 of the sugar is remaining to make the cakes.
Divide 1/4 by 3 to figure out how much will be in each cake.
1/4 / 3/1 is equivalent to 1/4(1/3). When you do the multiplication of these fractions you will find that,
1/12 of the bag of sugar will go into each cake.
<em><u>Question:</u></em>
4x + 2y = 0
- 4x – 9y= - 28
Solve each system by elimination
<em><u>Answer:</u></em>
The solution is x = -2 and y = 4
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
4x + 2y = 0 ------ eqn 1
-4x – 9y = - 28 ------- eqn 2
We have to solve the system of equations by elimination method
Add eqn 1 and eqn 2
4x + 2y -4x -9y = 0 - 28
0 + 2y - 9y = -28
-7y = -28
Divide both sides by -7
y = 4
<em><u>Substitute y = 4 in eqn 1</u></em>
4x + 2(4) = 0
4x + 8 = 0
4x = -8
Divide both sides by 4
x = -2
Thus the solution is x = -2 and y = 4

Answer:
x=500
Step-by-step explanation:
7/10=350/x
cross-multiply by multiplying 350 to 10 and multiply 7 to x.
example:
7•x
350•10
7x=3500
divide both sides by 7
-------------
x=500
