1.
5u - 2u = 3u (diff. between longest and shortest)
3u = 87cm
1u = 87cm ÷ 3 = 29cm
5u + 4u + 2u=11u
11u = 11 x 29cm = 319cm
Ans: 319cm
2.
9u = 1350
1u = 1350 ÷ 9 = 150
6u + 5u = 11u
11u = 11 x 150 = 1650
Ans: 1650
Solution:
<u>Given:</u>
<u>Solve the equation by isolating the variable.</u>
- => 18 = 2b
- => 2b/2 = 18/2
- => b = 9
The value of b is 9.

Answer:A
Step-by-step explanation: 14% of the mothers work part-time in families where the father works part-time while 7% of the mothers work part-time in families where the father is not working.
Your answer is 0.8 or 80%
Explanation:
Consider the ratio written like a fraction:
<span><span>Count of sandwichescount of people</span>→<span>46</span></span>
But we need the count of sandwiches for 1 person. So we need to change the 6 people into 1 person. To change 6 into 1 divide it by 6
<span>6÷6=1</span>
For ratios, when multiplying or dividing, what we do to the bottomwe do to the top.
So to change <span>46</span> into what we want we apply
<span><span><span>4÷6</span><span>6÷6</span></span>=<span><span>23</span>1</span>← <span>Count of sandwichescount of people</span></span>
So each person ends up with <span>23</span> of a sandwich
<span>Now see where the shortcut comes from <span>46</span>=<span>23</span><span> of a sandwich</span></span>
