Answer:C
Step-by-step explanation:
Dante wrote several equations and determined that only one of the equations has infinitely many solutions. Which of these equations has infinitely many solutions?
6 (x + 3) + x = 7 x + 2 + 1
6 (x + 3) + x = 7 x + 5
6 (x + 3) + x = 6 x + 3 + 15
6 (x + 3) + x = 7 x + 9 + 9
9514 1404 393
Answer:
6 (x + 3) + x = 7 x + 9 + 9
Step-by-step explanation:
The equation will have an infinite number of solutions if the left side is equal to the right side. The left side in each case is 7x+18.
The right sides are (in the order shown) ...
= 7x +3
= 7x +5
= 6x +18
= 7x +18 . . . . . . matches the left side
The equation 6 (x + 3) + x = 7 x + 9 + 9 will have infinitely many solutions.
Kayla is building a custom frame using reclaimed wood. She needs the frame to be 14 1/2 inches wide by 9 1/4 inches long. She has two pieces of wood which are 18 inches long and two pieces which are 12 inches long. How much extra wood will she have. She will have two pieces blank inches long and two pieces blank inches long
Answer:
12 1/2 inches extra wood.
Step-by-step explanation:
From the question, the measurements given for the frame are ;
Length, l = 9 1/4 in -----write as improper fraction : 37/4 in
Width, w= 14 1/2 in -------29/2 in
This should tell you that custom frame will be rectangular in shape.
Find the total perimeter of the frame which will be total length needed in inches for the frame.
P= 2{l+w}
[tex]P=2(\frac{37}{4} +\frac{29}{2} )\\\\\\P=2( \frac{95}{4} )=\frac{95}{2}[/tex]
P= 95/2 in ------total length required for the frame
Available pieces of wood are;
Two pieces of 18 in long = 2*18 = 36 in
Two pieces of 12 in long = 2*12 = 24 in
Total available length from the pieces of wood = 36 + 24 = 60 in
Extra wood available :
60/ 1 - 95/2 = 25/2 in
In mixed fraction : 25/2 = 12 1/2 inches extra wood.

The volume of a cube is given by the formula V=S3 Find the Volume when each side of the cube is 3 1/2 inches. Question 4 options: Blank # 1 Blank # 2 Blank # 3
Answer:
V = 343/8 cubic inches
Step-by-step explanation:
Here, we want to find the volume of the cube given the length of its side
Mathematically, the volume of a cube is L^3
where L represents the length of one of its side.
3 1/2 = 7/2 inches
Thus we have; 7/2 * 7/2 * 7/2 = 343/8 inches cube
Find the percent to 125 centimeters to 87.5 centimeters
Answer:
1.428571428571429
Step-by-step explanation:
Answer: If you are asking how to subtract 125 centimeters and make it 87.5, you have to subtract from 125. The easiest way to do this is to subtract 87.5 from 125, getting 37.5. So, if you add 37.5 to 87.5, you will have 125. So, the correct answer is to subtract 37.5 to get 87.5.

A School District transported 310 students and teachers to a zoo in buses and vans. Each bus transported a total of 20 students and teachers Each van transported a total of 10 students and teachers. There were 5 more buses than vans. What is the total number of students & teachers who rode the buses to the zoo? What is the total number of students & teachers who rode the vans to the zoo?
Answer:
240 Students and teachers rode buses
70 students and teachers rode vans
Step-by-step explanation:
Let the total number of buses be x
Let the total number of vans be y
If there were 5 more buses than vans, then x = y+5 ...... 1
If each bus transported a total of 20 students and teachers and each van transported a total of 10 students and teachers then:
20x + 10y = 310 ..... 2 (where 310 represents the total number of students and teachers in the school district)
Substitute equation 1 into 2:
20(y+5)+10y = 310
20y+100+10y = 310
30y = 310-100
30y = 210
y = 210/30
y = 7
Substitute y = 7 into equation 1 to get x:
From 1: x = y+5
x = 7+5
x = 12
The total number of buses are 12 while the total vans are 7
If each bus transported a total of 20 students and teachers, the total number of teachers and students that rode the buses to the zoo will be 20*12 = 240 teachers and students
If each van transported a total of 10 students and teachers, the total number of teachers and students that rode the vans to the zoo will be 10*7 = 70 teachers and students

After 10 days Mr. Monasterio had eaten 43 burritos. After 15 days, he had eaten 78 burritos. What is the rate of change? Label your answer with units.
Answer:
7 burritos/day
Step-by-step explanation:
Given data
Initial day =10
Final day =15
Initial burritos consumed=43
Final burritos consumed =78
Let the constant k = rate of change
change in days = 15 - 10 = 5
change in number of burritos = 78-43=35
k = 78-43/15-10
k = 35/5
k = 7
Since k = change in number of burritos/change in days
7 burritos/day

Angles A and B are complementary. Angle A is 87°. Find the
measure of angle B.
Answer:
m∠B = 3°
Step-by-step explanation:
Complementary angles when combined will equal 90° in total.
∠A + ∠B = 90
m∠A = 87° {Given}
Plug in 87 for ∠A in the given equation, and solve for ∠B
87 + ∠B = 90
Isolate the variable. Subtract 87 from both sides of the equation:
87 (-87) + ∠B = 90 (-87)
∠B = 90 - 87
∠B = 3°
m∠B = 3° is your answer.

Step-by-step explanation:
–4(x – 26) = –200
x =
Answer:
x = 81
Step-by-step explanation:
With this equation, you would first want to multiply -4 to x and -26.
Your new equation is now -4x + 124 = -200
You would then subtract 124 from both sides leaving you with
-4x = -324
Finally, you would divide both sides by -4, leaving you with
x = 81
I hope this helps!
