C. 8 1/6
D. 8 5/6
Answer:
D. 8 5/6
Step-by-step explanation:
Hi there !
5 1/6 + 3 2/3 =
= (5×6 + 1)/6 + (3×3 + 2)/3
= 31/6 + ²⁾11/3
= 31/6 + 22/6
= (31 + 22)/6
= 53/6
= 8 5/6
Good luck !

I need help finding the values of x and y!!
Answer:
x= 22
y = 35
Step-by-step explanation:
The base angles of a isosceles triangle are equal
3x-11 = 2x+11
Subtract 2x from each side
3x-2x -11 = 2x-2x+11
x-11 = 11
Add 11 to each side
x-11+11 = 11+11
x = 22
The sum of all the angles in a triangle is 180
3x -11 + 2x+11 + 2y = 180
Combine like terms
5x +2y = 180
5*22 + 2y = 180
110 + 2y = 180
Subtract 110 from each side
110+2y-110 = 180-110
2y = 70
Divide by 2
2y/2 =70/2
y = 35
Round 35.367 to the nearest tenth.
Step-by-step explanation:
35.4
Answer:
35.4
Step-by-step explanation:
To round 35.367 to the nearest tenth consider the hundredths’ value of 35.367, which is 6 and equal or more than 5. Therefore, the tenths value of 35.367 increases by 1 to 4.
35.367 rounded to the nearest tenth = 35.4
What in slope-intercept form, can go through the line ( a, 2a) and (-5a, 6a)
Answer:
y = -2/3x + 8/3aStep-by-step explanation:
Given points
(a, 2a) and (-5a, 6a)Slope-intercept form
y = mx + bSlope of the line is
m = (6a - 2a)/( -5a - a) = 4a/(-6a) = - 2/3The y-intercept is:
2a = -2/3*a + bb = 2a + 2/3ab= 8/3aSo the line is:
y = -2/3x + 8/3aAnswer:
y = -2/3 - 8/3a
Step-by-step explanation:
Find the slope using [ y2-y1/x2-x1 ]
6a-2a/-5a-a
4a/-6a
-2/3
Find the y-intercept.
y = mx + b
y = -2/3x + b
2a = -2/3(a) + b
-8/3a = b
y = -2/3 - 8/3a
Best of Luck!

(2x - 3x2 + 4x3 – 6x5) + (7x6 – 5x3 + 3x²)
Answer:
7x⁶ - 6x⁵ - x³ + 2x
Step-by-step explanation:
Step 1: Write expression
(2x - 3x² + 4x³ - 6x⁵) + (7x⁶ - 5x³ + 3x²)
Step 2: Combine like terms (x³)
7x⁶ - 6x⁵ - x³ - 3x² + 2x + 3x²
Step 3: Combine like terms (x²)
7x⁶ - 6x⁵ - x³ + 2x

Step-by-step explanation:
PLEASE HELP ,,,,1. If AMNP is an equilateral triangle, find the values of x
and y.
An equilateral triangle is a triangle in which all three sides have the same length[tex].[/tex]
⭆ 14 = 3x - 4
⭆ 3x = 14 + 4
⭆ 3x = 18
⭆ x = 18/3
⭆ x = 6
In equilateral triangle, all three internal angles are also same and each are of 60°.
⭆ 5y - 5 = 60
⭆ 5y = 60 + 5
⭆ 5y = 65
⭆ y = 65/5
⭆ y = 13
★ Final answer :
x = 6y = 13Hope It Helps!Answer:
x = 6y = 13Step-by-step explanation:
equilateral triangle, all sides are equal,
MN = MP
14 = 3x - 4
x = 18/3
x = 6
internal angles are also equal.
5y - 5 = 60 (180/3 = 60)
5y = 65
y = 13

The three Miller boys were calculating the volume of their new fish tank to determine how many gallons of water the tank can hold. Each brother measured a different dimension of the tank. Their measurements were 1 yard in length, 1 foot in width, and 18 inches in height.
1. There are approximately 7.5 gallons per cubic foot. If you want to know how many gallons of water the tank can hold, what unit of measure would you use to calculate the volume of the fish tank? Explain why
2. Determine how many gallons of water the fish tank can hold. Carefully show your work and include units of measure.
9514 1404 393
Answer:
ft33.75 galStep-by-step explanation:
1. The conversion factor is given in gallons per cubic foot. So, to avoid more conversion factors than necessary, it is convenient to use feet as the unit of measure.
__
2. The dimensions are ...
1 yd × 3 ft/yd = 3 ft . . . . length
18 in × 1 ft/(12 in) = 1.5 ft . . . . height
So, the volume is ...
V = LWH = (3 ft)(1 ft)(1.5 f) = 4.5 ft³
Then the number of gallons is ...
(4.5 ft³)×(7.5 gal/ft³) = 33.75 gal
