Answer:
So, Emily will spend, 11.52 unit on wire
and, Andy will spend 18.72 unit on wire.
Step-by-step explanation:
Cost of wire is =
= 
= 
=
= 0.04 unit/inch
We know that,
12 inch = 1 foot and
1 yard = 3 foot [Note that unit of a quantity always denoted singular].
So, Emily will spend,
unit
= 11.52 unit on wire
and, Andy will spend,
unit
= 18.72 unit on wire.
A rational number can be expressed in the form a/b, where a and b are other integers. To satisfy this definition, 0.9 can be written as 9/10, 18/20, 90/100, etc.
Hey there! I'm happy to help!
Here is our equation
3x - 4 (2x - 5) = 15
First, we will sue the distributive property to remove the parentheses. The term outside the parentheses is -4, so that is what we multiply the insides by.
3x-8x+20=15
We combine our like terms (our x-values).
-5x+20=15
We subtract 20 from both sides.
-5x=-5
We divide both sides by -5.
x=1
Have a wonderful day and keep on learning! :D
Answer:
23: 21
25: 1
Step-by-step explanation:
<u>Question 23</u>:
1) add the whole numbers together: 15+5=20
2)To add fractions, both need to have the same denominator. Find a number that is a multiple of both denominators (in this case 55)
→
(multiply the numerator and denominator by 5)
→
(multiply the numerator and denominator by 11)
3) add the fractions together
+
=
(add the numerators)
4) Turn the improper fraction into a mixed number
Divide 78 by 55. You'll get a whole number and a remainder. The remainder is the new numerator: In this case 55 enters 78 once with a remainder of 23. Therefore:
1
5) Add the whole numbers together to get the final answer:
20+1= 21
Answer: 21
<u>Question 25</u>:
Follow the above steps but subtract instead of adding
