Answer:
20*x
Step-by-step explanation:
alright so lets start with how many cents are in a dollar
100 cents per dollar
we need to find 20 pounds so we can use an equation i made
lets say it's 22c per pound
20*x=$
lets try plugging in 22
20*.22=$4.20
Answer: The number is -20
Step-by-step explanation:
Take each part of the sentence and write what it is telling us:
3 less than the <u>quotient of a number and 5</u> is -7
The <u>quotient of a number and 5</u> is (X/5), where X is the "number."
<u>3 less than</u> is (X/5) - 3
<u>is -7 </u> is = -7
Therefore:
3 less than the quotient of a number and 5 is -7 is: (X/5) - 3 = -7
---
(X/5) - 3 = -7
(X/5) = -4
X = -20
===
See if this works:
3 less than the quotient of <u><em>-20</em></u> and 5 is -7
(-20/5) = -4
Three kless than -4 is -7: It works
27/40-
7/8- 1/5
You just convert it into 40th.. 35/40 - 8/40
Answer:
2x +3y=1⇒equation 1
3x=2y+8
3x-2y=8⇒equation 2
by elimination method,
2x+3y=1 ×2
3x-2y=8 ×3
4x+6y=2
9x-6y=24
cut 6y and -6y
4x+6y=2
9x-6y=24
---------------
13x+0=26
13x=26
x=26/13
x=2
substitute x=2 in equation 1
2(2)+3y=1
4+3y=1
3y=1-4
3y=-3
y=-3/3
y=-1
therefore, x=2 and y=-1
hope it helps u!
