Answer:
x = - 4, x = 5
Step-by-step explanation:
(5x - 25)(x + 4) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
5x - 25 = 0 ⇒ 5x = 25 ⇒ x = 5
Answer:
x = - 4, x = 5
Step-by-step explanation:
(5x - 25)(x + 4) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
5x - 25 = 0 ⇒ 5x = 25 ⇒ x = 5
Hence, the correct answer is x=-4, x=5

For what value of x, the slope of the line passing through P(-2,-8) and Q(5,x) is 1?
Answer:
[tex]x=-1[/tex]
Step-by-step explanation:
The equation for slope is:
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
In this case, x would represent, [tex]y_2[/tex]. Therefore...
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\1=\frac{x-(-8)}{5-(-2)}\\1=\frac{x+8}{5+2}\\1=\frac{x+8}{7}\\\\Multiply\ 7\ to\ both\ sides\\\\7=x+8\\\\\ Subtract\ 8\ from\ both\ sides\\\\x=-1[/tex]
how many ninths are there in 9 2/3
Answer:
87
Step-by-step explanation:
9 2/3 = 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 9/9 + 6/9 = 87/9
Answer: 87 ninths
Step-by-step explanation:
See how many 1/9ths fit inside 9 2/3 using division
[tex]9\:\frac{2}{3}\div \frac{1}{9}[/tex] or
[tex]\frac{29}{3}\div \frac{1}{9}[/tex]
[tex]=\frac{29}{3}\times \frac{9}{1}[/tex]
[tex]= \frac{87}{1}[/tex]
[tex]=87[/tex]
Test to see if 1/9 goes into 9 2/3 87 times
87 * 1/9
[tex]= \frac{87}{9}[/tex]
[tex]=\frac{29}{3}[/tex]
29/3 as a mixed fraction is 9 2/3. So therefore, there are 87 ninths in 9 2/3

Ward finances $20,000 to purchase a car. If he gets a 2. 5% interest rate regardless of loan length, how much interest will Ward save if he finances the $20,000 for 3 years rather than 5 years? A) $1,000 B) $10,000 C) $333. 33 D) $3,333. 33.
The total amount of interest will Ward save if he finances car the $20,000 for 3 years rather than 5 years is $1000.
What is simple interest?Simple interest is the amount charged on the principal amount with a fixed rate of interest for a time period. Simple interest calculated only on the principal amount.
The formula for the simple interest can be given as,
[tex]I=\dfrac{Prt}{100}[/tex]
Here, (I) is the interest amount earned on the principal amount of (P) with the rate of (r) in the time period of (t).
Ward finances $20,000 to purchase a car. The rate of interest is 2.5% regardless of loan length. The interest amount of the car for three years is,
[tex]I_3=\dfrac{20000\times2.5\times3}{100}\\I_3=1500[/tex]
The interest amount of the car for five years is,
[tex]I_3=\dfrac{20000\times2.5\times5}{100}\\I_3=2500[/tex]
The amount of interest Ward save,
[tex]C=2500-1500\\C=1000[/tex]
Thus, the total amount of interest will Ward save if he finances car the $20,000 for 3 years rather than 5 years is $1000.

Area of the circle is the area covered by that circle. The area of the circle whose circumference is 7π m is 12.25π m².
What is the area of a circle?The area of the circle is the area covered by that circle. It is given by the formula,
[tex]\text{Area of the circle}=\pi r^2[/tex]
where r is the radius of the circle.
As it is given that the circumference of a circle is 7π m. Therefore, the radius of the circle can be written as,
[tex]\text{Circumference of the circle} = 2\pi r[/tex]
[tex]7 \pi = 2 \pi r\\\\r = 3.5\rm\ m[/tex]
Now, we know the formula of the area of a circle, therefore, the area of the circle can be written as,

in planning her retirement, liza deposits some money at 4.5% interest, with twice as much deposited at 5%. Find the amount deposited at each rate if the total annual interest income is $2755
Answer:
For this problem, we can assume that we deposits X money at 4.5% interest, than we can know that 2X were deposited at 5% interest, therefore we can get the equation of: 4.5%*X+5%*2X=2755, than we can get X=19000, so the 2X=38000, than we can concluded that: she deposited $19000 at 4.5% and $38000 at 5%.

Kevin can mow the lawn in 1.5 hours. Together, Kevin and Eric can mow the lawn in 30 minutes. How long will it take Eric to mow the lawn alone?
HELP PLS
Answer:
45
Step-by-step explanation:
These work problems are always done in terms of fractions ie if both (Kevin & Eric) took 30mins to mow and Kevin took 1.5hrs (90mins) alone then we can make an equation like below
1/time took for both = 1/time took for Kevin + 1/time took for Eric
1/30 = 1/90+1/x ==> calling time took for Kevin x
solving the above 1/x = 1/30-1/90
1/x=2/90
x=45
Given that Kevin takes 1.5 hours to mow the lawn alone and together
with Eric it takes 30 minutes The time it takes Eric alone is 45 minutes.
How can the rate of work of Eric be found?The time it takes Kevin to mow the lawn, K = 1.5 hours
The time it takes Kevin and Eric to mow the lawn, B = 30 minutes = 0.5 hours
Required:
The time it takes Eric to mow the lawn alone.
Solution:
Let K represent the time it takes Kevin to mow the lawn alone and let E
represent the time it takes Eric to mow the lawn alone, we have;
[tex]\mathbf{\dfrac{1}{K} + \dfrac{1}{E} }= \dfrac{1}{T}[/tex]
Which gives;
[tex]\dfrac{1}{1.5} + \dfrac{1}{E} = \dfrac{1}{0.5}[/tex]
Which gives;
[tex]\dfrac{1}{E} = \dfrac{1}{0.5} - \dfrac{1}{1.5} =\dfrac{4}{3}[/tex]
Therefore;
[tex]E = \dfrac{1}{\dfrac{4}{3} } = \dfrac{3}{4} = \mathbf{ 0.75}[/tex]
The time it takes Eric to mow the lawn alone, E = 0.75 hours
0.75 hours = 0.75 × 60 minutes = 45 minutes
The time it takes Eric to mow the lawn alone, E = 45 minutes

Kevin needs to buy shrubs for his yard. He can buy 6 shrubs for $72.00 at a nursery and 7 shrubs for $77.00 at a garden store.
Answer:
He would pay less at the garden store.
Step-by-step explanation:
We have to find the unit prices of both shrubs.
The unit price is the cost per unit, and to find the unit price, divide the price by the number of units.
72/6 = 12
77/7 = 11
He would pay less at the garden store because the unit price is lower than the nursery.
