Olivia and Isabella each earn d dollars for each dog she walks. One day, Olivia walks 6 dogs and gets $8 in tips. That same day, Isabella walks 9 dogs and gets $12 in tips.
a. Olivia writes 6d + 8 + 9d + 12 to represent the amount
they earn together. Isabella writes 5(3d + 4). Are their
expressions equivalent? Show your work.
Answer:
Yes they are equivalent, both equations equals [tex]15d+20[/tex]
Step-by-step explanation:
We first simplify Olivia's equation
[tex]6d + 8 + 9d + 12[/tex]
1. we combine like terms in the equation: [tex]6d + 8 + 9d + 12[/tex]
[tex]6d+9d[/tex]
[tex]8+12[/tex]
[tex]15d+20[/tex]
Now we simplify Isabella's
[tex]5(3d + 4)[/tex]
1. we do distributive property
[tex]5*3d[/tex]
[tex]5*4[/tex]
[tex]15d+20[/tex]

3 (3x+5)=2 (2x-5) solve for x
Answer:
-5
Step-by-step explanation:
3(3x + 5) = 2(2x - 5)
9x + 15 = 4x - 10
9x - 4x = -15 - 10
5x = - 25
x = -5
Pleaseee help in 2 hours helpppp meeee
Answer:
C
Step-by-step explanation:
y = mx + b
Adding by three each time so m is 3
B is 2 since that is what y is when x equals 0
So it is 3x + 2
Answer:
C
Step-by-step explanation:
Hi,
We know from the table that wherever x is 0 that is the y-intercept. So, in the table, when x is 0, y is 2. The y-intercept is 2.
Now, the slope. We can tell that as x is being added by 1, y is being added by 3. The slope is 3.
So, your line is y = 3x + 2
C is your correct answer.

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 1661 square feet? Use 3.14 for .
Answer: 23 feet
Step-by-step explanation:
The question simply means that we should calculate the radius of the circle. In this case, the area has been given to be 1661ft².
Area of a circle = πr²
πr² = 1661ft²
3.14(r²) = 1661
r² = 1661 / 3.14
r² = 528.98
r = ✓528.98
r = 23
The solution is 23 feet.
(Factorize): x^2 + 4x + 4 - 9y^2
Answer:
x²^2 + 4x + 4 - 9y²=(x+2-3y) (x+2-3y)
Step-by-step explanation:
hello :
x²+4x+4 = x²+2(2x)+2²=(x+2)² use identity : (a+b)² = a²+2ab+b²
( x² + 4x + 4) - 9y² = (x+2)²-(3y)² = (x+2-3y) (x+2-3y) use identity :
a²-b² =(a-b)(a+b)

What is the value of t, the critical value of the t distribution with 8 degrees of freedom, which
satisfies the condition that the probability is 0.10 of being larger than t?
a) 1.415
(b) 1.397
(c) 1.645
(d) 2.896
(e) 0.90
The critical value of t has probability 0.10 to the right with 8 degrees of freedom is 1.3968.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
The t-distribution with 8 degrees of freedom has probability 0.10 to the right of t.
That is, df = 8,
α = 0.10 by using these values, the critical value of t is obtained.
From the t-distribution table:
The critical value is 1.3968.
The critical value of t has probability 0.10 to the right with 8 degrees of freedom is 1.3968.
Therefore, the critical value of t has probability 0.10 to the right with 8 degrees of freedom is 1.3968.

Answer:
Part A: A
Part B: [tex]x+18=8(2x-6)-18x[/tex]
Step-by-step explanation:
When in Step 1, the equation is multiplied by two, the second term, -9x, is not doubled as well. Thus the answer above for Part B, is what Step 1 should look like.
Finishing evaluating the problem:
[tex]x+18=16x-48-18x[/tex]

Mr. Morris deposits $3,000 into a savings account that compounds annually by 16%. If 2 years
pass, how much money does Mr. Morris have in his savings account?
Answer:
$4036.8
Step-by-step explanation:
Given data
Principal= $3,000
Rate=16% = 0.16
Time= 2 years
The expression for the compound interest is
A=P(1+r)^t
substitute our data into the expression to solve for A
A=3000(1+0.16)^2
A=3000(1.16)^2
A=3000*1.3456
A=$4036.8
Hence the savings after 2 years is $4036.8

Do 12/15 and 8/10 have the same value? Explain your answer in complete sentences. (NO LINKS PLEASE)[tex]\frac{12}{15} and\frac{8}{10}[/tex]
Answer:
They are the same.
Step-by-step explanation:
12 divided by 15 = .8 and 8 divided by 10= .8
.8=.8
Hope this helps!
Answer:
Yes, and see below for sentences.
Step-by-step explanation:
Yes, they do have the same value. If you create equivalent fractions for each of them with a common denominator, you can compare the numerators to each other.
12/15 is equal to 24/30 when you multiply numerator and denominator by 2, and 8/10 is equal to 24/30 when you multiply numerator and denominator by 3.
