Step-by-step explanation:
Answer:2+2=fish
Step-by-step explanation:
Answer:
Divide £700 in the ratio 5:3:2.
The total number of 'parts' in this ratio
= 5 + 3 + 2 = 10.
So, to work out how much of the total corresponds to 1 part, we need to divide the total sum by the total number of parts: 700/10 = £70.
Now, we can multiply the amount we know for 1 part by each value in the ratio.
Step-by-step explanation:
70 × 5 = £ 350
70 × 3 = £ 210
70 × 2 = £ 140
<u>Answer:</u> x = 1/5 and y= -7/5
Step-by-step explanation: Let's solve your system by elimination.
Multiply the first equation by -3,and multiply the second equation by 1.
-3 (x - 2y = 3)
1 (3x - y = 2)
Becomes:
-3x + 6y = -9
3x -y = 2
Add these equations to eliminate x:
5y = -7
Then solve 5y = -7
5y/7 = -7/5
y = -7/5
Now that we‘ve found y, let’s plug it back in and solve for x.
Write down an original equation:
x - 2y = 3
<h3>
Substitute -7/5 for y in x - 2y = 3:</h3><h3>
x - 2 (-7/5) = 3</h3><h3>
x + 14/5 = 3</h3><h3>
x 14/5 + -14/5 = 3 + -14/5 (Add (-14)/5 to both sides)</h3><h3>
x = 1/5</h3><h3><u>
Answer: </u></h3><h3>x = 1/5 and y = -7/5</h3><h3 /><h3 /><h3 />
