By better I am assuming you meant faster so,
18 ÷ 2 = 9
22 ÷ 2.5 = 8.8
9 > 8.8
therefore Emily has the faster rate.
Hello,
To this question, It's only directly sum the equations:
y + y = 7x - 7x +7+19
2y = 0x + 26
2y = 26
y = 26 ÷ 2
y = 13
Now only to replace y = 13 in the equation of up or of down.
Then stay:
y = 7x + 7
13 = 7x + 7
7x = 13 -7
7x = 6
x = 6 / 7
Answer:
2) A, 3) Shawn is looking for a good book, he reads 12 books and then decides to read 1/4 of the amount he already read. How many books has Shawn read in total? 4) A, C, E. 5) 4
Step-by-step explanation:
2) Elena already walked 12 miles, she then walks another 1/4 of those 12 miles. The answer is A.
3) Shawn is looking for a good book, he reads 12 books and then decides to read 1/4 of the amount he already read. How many books has Shawn read in total?
4) to find the answers figure out how much they multiply one number by and multiply the other number by that amount. For example, the ratio 2:5 can be the same as 4:10 because you are multiplying the original ratio by 2 to get the new ratio.
5) The diameter of a circle is the length of one side to another. to find the length of the outer edge you need to find the circumference. To find the circumference of a circle you must use 
*Diameter. To find the answer we must use 180/D. Since pi can not be defined we will use 3.14 as a rough estimation. 3.14*12=37.68. 180/37.68=4.777070064. Since it doesn't make much sense to do .8 of a invitation then we must round down. The answer is 4.
Answer:
Answer: C) 60. Explanation: 60 is not a multiple of 8. Subject: HCF and LCM - Quantitative Aptitude - Arithmetic Ability. Exam Prep: Bank Exams. Q: The HCF of two number is 6 and their LCM is 108.If one of the number is 12,then the other is. A) 27.

The equivalent expression of (1.4³/1.2⁴)⁻⁶ is gotten as; 1.2²/1.4³
<h3>How to use rule of exponents?</h3>
We are given the expression as;
(1.4³/1.2⁴)⁻⁶
Now, according to rule of exponents in multiplication, we know that;
x² × x³ = x² ⁺ ³ = x⁵
Thus, applying that rule of exponents above to our given problem and we have;
(1.4³/1.2⁴)⁻⁶ = (1.4³ ⁻ ⁶)/(1.2⁴ ⁻ ⁶)
⇒ 1.4⁻³/1.2⁻²
Also according to rule of exponents we know that;
x⁻¹ = 1/x
x⁻² = 1/x²
Thus;
1.4⁻³/1.2⁻² = (1/1.4³)/(1/1.2²)
⇒ 1.2²/1.4³
Thus, we can conclude about the question that the equivalent expression of (1.4³/1.2⁴)⁻⁶ is gotten as; 1.2²/1.4³
