Hey there!
For equations like this I usually find the GCF or Factors of the given numbers for both of numbers and factor/solve it from there!
So, I’ll do the same thing for you.
[tex]\bf{4x: 1,2,4,\& \ x}\\ \bf{16: 1,2,4,8}}[/tex]
GCF: [tex]\bf{4}[/tex]
[tex]\boxed{\bf{Answer: 4(x - 4)}}\checkmark[/tex] (Just distribute and it’ll convert back to the equation in your question
Good luck on your assignment and enjoy your da!

I need help with square roots. I would really appreciate it if you help me understand them. Thank you! I'll give you 10 points and a five star review for a good answer.
Answer: 9/8
Step-by-step explanation:
The square root of this is 9/8 because when you square 9/8, you get 81/64, and when you square root it, you get 9/8.
The easiest way tho is knowing that when you square a number and square root the square, you get the same number, cuz the square root cancels the square. Does that make sense?
Anyways hope this helped!

Derrick's Dog Sitting and Darlene's Dog Sitting are competing for new business. Derrick's Dog Sitting
charges $16 plus $7 per hour. Darlene's Dog Sitting charges $20 plus $5 per hour.
Part 1 out of 2
Complete and solve the equation that can be solved to find the number of hours for which the total cost
will be the same for the two services. In your equation, use x to represent the number of hours of dog
sitting
The equation is
The total cost will be the same for the two services at
hours.
Answer: both services will cost the same if it is for 3 hours service.
Step-by-step explanation: Hope this helps.
Define x: Let x be the number of hours
Derrick Dogs sitting:
Fixed charged=$12
Hourly change=$5
Total charge=12+5x
Darlene dog sitting:
Fixed charged=$18
Hourly change=$3
Total charge= 18+3x
Find the total number of hours so that both cost are the same:
12 + 5x = 18 + 3x
5x - 3x = 18 - 12
2x = 6
x = 3
ANSWER: both services will cost the same if it is for 3 hours service
Answer:
3 hours hon

GUYS PLEASE HELP I MARK BRAINLIEST 5 STARS IM SORRY ABOUT THE POINTS I ONLY HAVE 13 Andre’s school orders some new supplies for the chemistry lab. The online store shows a pack of 10 test tubes costs $4 less than a set of nested beakers. In order to fully equip the lab, the school orders 12 sets of beakers and 8 packs of test tubes.
Write an equation that shows the cost of a pack of test tubes, t, in terms of the cost of a set of beakers, b.
t=b-4
The school office receives a bill for the supplies in the amount of $348. Write an equation with t and b that describes this situation.
b+t=348
Since t is in terms of b from the first equation, this expression can be substituted into the second equation where t appears. Write an equation that shows this substitution.
b+(b-4)=348
b=176
How much did the school pay for a set of beakers? $____
How much did the school pay for a pack of test tubes? $____
Answer:
this is not originally by me
Step-by-step explanation:
10t = b - 4
12b+8t = $348
This is a system of equations. I’ll be solving through substitution.
In the first equation. solving for b (the easier variable to isolate) gives you:
b = 10t + 4
Substitute this into the second equation:
12(10t+4) +8t = 348
120t+48+8t = 348
128t = 300
t = 2.34375 —> round it to the nearest cent to get 2.34 dollars
b = 10t+4
b = 10(2.34)+4
b = 27.4 dollars

Answer:
20cm squared
Step-by-step explanation:
so the scale factor is 1:2 so you just double the area so,
10cm squared x 2 = 20cm squared
Answer:
D: 40
Step-by-step explanation:
If the scale factor is 1:2 it means that each side is twice as big after being scaled. However, because the area is width * height that means that the area of the scaled one gets doubled two times, so is actually 4x bigger. This means the answer is 4 * 10 = 40 square cm

Zachary places daisies and magnolias in a vase. If daisies cost x dollars, magnolias cost y dollars and a vase costs v dollars, mark all equations which represent the cost of 20 vases of 40 daisies and 80 magnolias.
Answer:
[tex]Total = 20v + 40x + 80y[/tex]
[tex]Total = 20(v + 2x + 4y)[/tex]
Step-by-step explanation:
The options were not given,en but the question can still be solved.
Given
[tex]Daises = \$ x[/tex]
[tex]Magnolias = \$ y[/tex]
[tex]Vase = \$ v[/tex]
Required
Determine the cost of 20 vases, 40 daises and 80 magnolias
If 1 vase costs $v, then
[tex]20\ vases = 20 * v[/tex]
[tex]20\ vases = 20v[/tex]
If 1 daises costs $x, then
[tex]40\ daises = 40 * x[/tex]
[tex]40\ daises = 40x[/tex]
If 1 magnolias costs $y, then
[tex]80\ magnolias = 80 * y[/tex]
[tex]80\ magnolias = 80y[/tex]
[tex]Total = 20v + 40x + 80y[/tex]
Another expression that represents the total is to factorize the expression.
[tex]Total = 20(v + 2x + 4y)[/tex]
What is the area of the football field in the scale drawing? Assume that the field is shaped like a rectangle.
Answer:
i mean might as well get free points now that its 2 weeks old
Step-by-step explanation:
Answer:
Pythagorean Theorem: the diagonal of the football field is the hypotenuse. Let´s say the diagonal is C and the two other sides are A and B.
Width = A
Length = B
Diagonal = C
so: a2+b2=c
2502+1002=c2
2500+10000=c2
12500=c2
c=√12500
c=111.80 yards

Find all possible solutions for x and y such that △ABC is congruent to △DEF.
△ABC: sides of length 19, 25, and 3x − 3.
△DEF: sides of length 25, 15, and 5 − y.
△ABC ≅ △DEF when x is ___ and y is ___.
Answer:
Step-by-step explanation:
it means the ABC And DEF have side lengths of 15,19, 25
so 3x-3 = 15
x = 6
5-y = 19
so y = -14
