Hey there!
Explanation:
First, you had to do is add by 13 from both sides of an equation.
Then, simplify or add by the numbers.
Next, you can also divide by 3 from both sides of an equation.
And finally, simplify and divide by the numbers,
*The answer must have a positive sign.*
Hope this helps!
Answer:
see explanation
Step-by-step explanation:
sum the parts of the ratio, 5 + 6 + 3 = 14 parts
Divide number of members by 14 to find the value of one part of the ratio.
560 ÷ 14 = 40 ← value of 1 part of the ratio
(i)
number of women = 6 × 40 = 240
(ii)
number of children = 3 × 40 = 120
13x + 5y = 16
2x - 8y = 20
Multiply the equations;
13x + 5y = 16 [x2]
2x - 8y = 20 [x13]
26x + 20y = 32
26x - 104y = 260
Reverse the signs on one equation;
26x + 20y = 32
-26x + 104y = -260
'-26x' gets cancelled, leaving;
20y = 32
104y = -260
20y + 104y = 124y
32 - 260 = -228
124y = -228
y = -228 / 124
y = -1.84
Substitute in one equation and find 'x'.

Answer:
Yes
Step-by-step explanation:
7/8 + 5/8 = 12/8 = 1 1/2
