In the system of equations 4x + 2y = 10 and 12x - 3y = 3, what is the solution?
Hint: SOLVE BY ELIMINATION
Answers
Answer:
solution = (3, 11)
Step-by-step explanation:
4x + 2y = 10
*subtract 4x from both sides*
2y = -4x + 10
*divide by 2* --> y = -2x +5
12x - 3 y = 3
*add 3y to both sides*
12x = 3y + 3
*subtract 3 form both sides*
12x - 3 = 3y
*divide by 3* --> y = 4x - 3)
2x + 5 = 4x - 1
*subtract 2x form both sides*
5 = 2x -1
*add 1 to both sides*
6 = 2x
*divide by 2x* --> x = 3
y = 2(3) + 5 (plug in 3 for x to solve for y)
y = 6 + 5
y = 11

^\circ

degrees
Answers
Answer:
72 degrees
Step-by-step explanation:
Find the diagram attached. We are to find the length of the arc
Measure of arcABC = rtheta
16π = 10 theta
theta = 16*180/10
theta = 16 * 18
theta = 288degrees
central angle = 360 - 288 = arc AC
central angle = 72degrees
Hence the arc measure of AC is 72 degrees
A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 90 pounds. The truck is transporting 50 large boxes and 65 small boxes. If the truck is carrying a total of 4950 pounds in boxes, how much does each type of box weigh?
Answers
Answer:
small = 30 pounds
large = 60 pounds
Step-by-step explanation:
two equations can be derived from the question
x + y = 90 eqn 1
50x + 65y = 4950 eqn 2
x = small box
y = big box
multiply equation 1 by 50
50x + 50y = 4500 eqn 3
subtract equation 3 from 2
15y = 450
y = 30
substitute for y in equation 1
y = 60

6, 8, 11, 12, 2x – 8, 2x + 10, 35, 41, 42, 50
are in ascending order. If the median is 25,
find the value of x.
Ans: 12
Answers
Answer:
12
Step-by-step explanation:
(2x-8+2x+10)/2 = 25
(4x+2) = 2×25
4x+2 = 50
4x = 50-2
4x = 48
x = 48/4
x = 12
Answer:
x = 16.5 as the median in this term is 2x-8
and 2x-8 = 25
25+8=2x
33=2x
x=[tex]\frac{33}{2}[/tex]
= 16.5

If the area of the rectangle shown is given by the expression 3x2 + 72 - 6and the width is (a + 3), which of the
following would represent the length? Remember: A = lw (Hint: Box method multiplication may be helpful here!)
Answers
Answer:
3x - 2.
Step-by-step explanation:
The length = area / width.
The area 3x^2 + 7x - 6 = (3x - 2 )(x + 3)
so the length = (3x - 2 )(x + 3 ) / x + 3
= 3x - 2.

Answer:
113°
Step-by-step explanation:
triangles add up to 180°
180° - 34° - 33° = 113°
==============================================
Explanation:
For any triangle, the three interior angles must add to 180 degrees
34+33+x = 180
x+67 = 180
x = 180-67 ... subtract 67 from both sides
x = 113
This triangle is obtuse because the 113 degree angle is larger than 90 degrees. Also, the triangle is scalene because all three angles are different values (consequently, it means all three sides are different from one another).
Determine the volume of the space in the tank that still needs to be filled with water if the water is ⅓ ft. Deep
Answers
Answer:
11 1/9 ft^3
Step-by-step explanation:
find the complete question in the attached image
volume of the tank = length x width x height
2 x 5 x 1 2/3
2 x 5 x 5/3 = 50/3 = 16 2/3 ft^3
If the tank is 1/3 filled with water, the volume that needs to be filled with water is 1 - 1/3 = 2/3
volume that needs to be filled with water = 2/3 x volume of the tank
2/3 x 50/3 = 11 1/9 ft^3

x = 3y
4x + 5y = 34
solve for x and y
Help help
Answers
Answer: y=2 and x=6
Step-by-step explanation:
x=3y
4x+5y=34
From equation ( 1) x=3y thus substituting in eqn(2)
4(3y)+5y=34
12y+5y=34
17y=34
y=34÷17=2
Thus y=2
Putting y=2 in eqn(1)
x=3y
x=3(2)
x=6
Oscar rides his skateboard 5/8 mile in 1/4 hour. How fast, in miles does he ride his skateboard
Answers
Answer:
2.5 miles per hour
Step-by-step explanation:
[tex]\frac{1}{4}\times \frac{5}{8}[/tex]
Step 1: Apply the fraction rule: [tex]\frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}[/tex]
[tex]\frac{1}{4}\times \frac{5}{8}=\frac{1\times \:5}{4\times \:8}[/tex]
Step 2: Set up the fraction
[tex]\frac{5\times \:4}{8}[/tex]
Cancel the numbers: [tex]\frac{4}{8}=\frac{1}{2}[/tex][tex]=\frac{5}{2}[/tex]Convert to decimal[tex]\frac{5}{2} = 2.5[/tex]Therefore, Oscar's speed is 2.5 miles per hour.
