Answer:
The answer is 31/20.
Step-by-step explanation:
First, you have to have both fractions the same denorminator :
[tex] \frac{9}{4} - \frac{7}{10} [/tex]
[tex] \frac{9 \times 5}{4 \times 5} - \frac{7 \times 2}{10 \times 2} [/tex]
[tex] \frac{45}{20} - \frac{14}{20} [/tex]
Next, you have to subtract :
[tex] \frac{45}{20} - \frac{14}{20} [/tex]
[tex] \frac{45 - 14}{20} [/tex]
[tex] \frac{31}{20} [/tex]
Answer:
9/4 - 7/10= 31/20=1 11/20
Step-by-step explanation:
look first for their LCM=20
2 4 10
2 2 5
5 1 5
1 1
then you divide the LCM which is 20by one of the denominator and multiply by the numerator over denominator
20/4*9=45/20
20/10*7=14/20
now both have the same denominator so we just subtract the numerators
45-14/20=31/20
now we have subtracted and our answer is in improper fraction so we need to change to mixed fraction
31/20=1 11/20
*PLEASE ANSWER ASAP* (NEED HELP) Which statement below describes the expression ?
3 students split (division) 2 less (subtraction) than the number of pencils (p)
x+2x÷y-2y; x=4, y=-2
Substitute the value of the variable into the expression and simplify.
4
7. 3x + 2y2 let x = 4, y = 3
8. (x + 2)2 - (3x - 2) - 4 Let x = 3
9. x + 2y - 3z + xyz let x = 4, y = 3, z = 2
10. xyz let x = 4, y = 2, z = 3
Answer:
7. 24
8. -1
9. 28
10. 24
Step-by-step explanation:
substitute values into equations. don't forget the brackets :))
7. 3x + 2y2 Let x = 4, y = 3
= 3(4) + 2(3)2
= 12 + 12
= 24
8. (x + 2)2 - (3x - 2) - 4 Let x = 3
= ((3) + 2)2 - (3(3) - 2) - 4
= (5)2 - (9 - 2) - 4
= 10 - 9 + 2 - 4
= -1
9. x + 2y - 3z + xyz Let x = 4, y = 3, z = 2
= (4) + 2(3) - 3(2) + (4)(3)(2)
= 4 + 6 - 6 + 24
= 28
10. xyz Let x = 4, y = 2, z = 3
= (4)(2)(3)
= 24
the endpoints of a line segment are G(1,7) and H(-3,11). Find the coordinates of the midpoint M.
Answer:
The answer is
( 1 , 9)Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
G(1,7) and H(-3,11)
The midpoint is
[tex]M = ( \frac{ - 1 + 3}{2} , \: \frac{7 + 11}{2} ) \\ = ( \frac{2}{2} \: , \: \frac{18}{2} )[/tex]
We have the final answer as
( 1 , 9)Hope this helps you

Nicole started the say with $63.44 in her bank account. The bank deduced 186.56 from her account for her electric bill. Before the bank closed. Nicole made a deposit equal to 1/4 the amount her account was overdrawn. What was her balance at the end of the day?
Please explain how you got it if you can. :(
Answer:
- $92.34Step-by-step explanation:
Start balance:
$63.44Deduction:
$186.56Balance after deduction:
$63.44 - 186.56 = -$123.12Deposit:
$123.12*1/4 = $30.78Balance at the end of the day:
-123.12 + 30.78 = -$92.34
6. If n (E) = 40, n (A) = 22, n (ANB) = 8 and n ((AUB)') = 6, determine n(B)
Answer:
4
Step-by-step explanation:
First n(AUB)=n(E) - n((AUB)')
So n(AUB) = 40 - 6 = 34
Now all u hv to do is use the formulae,
n(AUB) = n(A) + n(B) - n(ANB)
So when u substitute above values,
34=22 + n(B) - 8
So,
n(B) = 4

Step-by-step explanation:
The government has decided to give a $1,000 tax rebate to each household in order to stimulate the economy. The government statistics say that each household will spend 90% of the rebate in goods and services. The businesses and individuals who benefited from that 90% will then spend 90% of what they received and so on.
What is the total effect of the rebate on the economy?
What will the total effect be if the rebate is $5000 to each household in order to stimulate the economy if each household will spend 90% of the rebate in goods and services?
Answer:
1.) The total effect of 90% of the $1,000 tax rebate would be 10,000 growth in the economy. Second question, the total effect of 90% of $5,000 would be 50,000 in growth in the economy. *Same concept different amount.
Step-by-step explanation:
1. S=[tex]\frac{a_1{} }{1-R}[/tex] 2. S=[tex]\frac{a_{1} }{1-R}[/tex]
S=[tex]\frac{1000}{1-0.9}[/tex] S=[tex]\frac{5,000}{1-0.9}[/tex]
S= 10,000 S=50,000

3x-2(x+3)=4x-9-x is the question
Answer:
[tex]\large\boxed{x = 7}[/tex]
Step-by-step explanation:
3x - 2(x + 3) = 4x - 9 - x
Start by multiplying 2 by the values in the parenthesis
3x - 2x + 6 = 4x - 9 - x
Subtract 3x - 2x and 4x - x
x + 5 = 3x - 9
Add 9 to both sides of the equation
x + 14 = 3x
Subtract x from both sides of the equation
14 = 2x
Divide both sides of the equation by 2
[tex]\large\boxed{x = 7}[/tex]

Find the distance of LINE SEGMENT rs.
Answer:
11
Step-by-step explanation:
QS = QR + RS ➡ 19 = -1 + x + 2x - 7 add like terms
19 = 3x - 8
27 = 3x
9 = x
RS = 2x - 7 so 2×9 - 7 = 11

which expression can be used to solve 3/5 ÷ 7/10
Answer:
Step-by-step explanation:
3/5 divided by 7/10
You use KCF
KCF stands for keep change flip
So it would be 3/5x10/7
3 10 15
_ x _ = _
5 7 7
you need to simplify it so the 5 in 3/5 would be a 1 and the 10 in 10/7 would be 5
