Answer:
a: b: c= 2: 9 :4
Step-by-step explanation:
Since b is the common variable in both fractions, ensure that the value of b in both fractions are the same. Here, the value of b in both fractions are 9. Thus, we can find their relationship with one another in terms of ratio by combining the two fractions together.
a: b: c= 2: 9: 4
This ratio is already in it's simplest form.
Answer:
width = 2.4
Step-by-step explanation:
so we know that the formula to get an area of a square/rectangle is A=lw, where <em>A </em>is the<em> </em><em>area</em><em>, </em><em>l</em><em> </em>is the<em> </em><em>length</em><em>, </em>and <em>w</em> is the <em>width</em><em>.</em>
we already have the area and the length, so all we need now is the width.
to find the width, simply plug in the area and the length into the formula, which will give you:
A = lw <em>-given formula</em>
12 = 5(w) <em>-plug in known variables</em>
12/5 = 5w/5 <em>-divide both sides by 5 to get x by itself</em>
2.4 = w <em>-turn the fraction into decimal if you prefer it that way</em>
<em>possible answers: </em><u><em>w = 2.4</em></u>, <em><u>w = 12/5</u></em>, or <u><em>w = 2 2/5</em></u>
Part A.
4m + 12 + 20m
2 (2m + 6 + 10m)
Part B.
2 (2m + 6 + 10m) = 4(m + 3 + 5m)
4m + 12 + 20m = 4m + 12 + 20m
24m + 12 = 24m + 12
My apologies...but I don't understand what you mean by algebraic properties.
Part C.
Assuming m = 2
4 (m + 3 + 5m)
4 (2 + 3 + 5 × 2)
4 (5 + 10)
4 (15)
60
4m + 12 + 20m
4 (2) + 12 + 20 (2)
8 + 12 + 40
20 + 40
60
Hope this helps!
Answer: True
Step-by-step explanation:
It passes the vertical line test, no two points are on the same x value
K=9S/2, total savings is S+9S/2=11S/2. So 9S/2÷11S/2=9/11. (a) The ratio is 9:11.
(b) Kieran’s savings are 9/11 of the total savings.
(c) Simon’s savings are S÷11S/2=2/11 of total savings (or simply subtract 9/11 from 1).
(d) K-S=28, 9/11-2/11=7/11 of the total savings, so 7/11 of the total savings is $28 and total savings is 11/7×28=$44.
CHECK
Kieran has 9/11 of $44 which is $36 and Simon has $8. 36/8=9/2 so the ratio is correct.
Simon has $28 less than Kieran and 36-8=28, which is correct.
