Answer:
1.64
Step-by-step explanation:
The first step to do is to line up the decimal points. We have to add a zero to 0.8 so that the decimal points will align (this does not change the value).
0.84
+0.80
Then bring down the decimal point into the answer column, and add like normal.
0.84

It’s all in the picture number 5!!!pleaseee help‼️‼️‼️‼️‼️‼️ASAP‼️‼️
We know that m<JKL = m<JKM + m<MKL
Let's substitute the values from the picture into our equation above.
10x - 11 = 43 + 8x - 20
Combine like terms.
10x - 11 = 8x + 23
Subtract 8x from both sides and add 11 to both sides.
2x = 34
Divide both sides by 2
x = 17
m<MKL = 8x - 20 = 8(17) - 20 = 136 - 20 = 116 degrees.
m<JKL = 10x - 11 = 10(17) - 11 = 170 - 11 = 159 degrees.

Rewrite in simplest terms: -5a – 86-8a + 1)
Answer:
- 13a - 85
Step-by-step explanation:
Given
- 5a - 86 - 8a + 1 ← collect like terms
= (- 5a - 8a ) + (- 86 + 1)
= - 13a + (- 85)
= - 13a - 85
Answer:
-13a - 85
Step-by-step explanation:
Collect the like terms
-5a -8a = -13a
Then calculate the sum
-86 + 1 = -85
and then you get your answer
-13a - 85
Find the first four terms of the sequence using the recursive formula.
Answer:
- 3, - 11, - 35, - 107
Step-by-step explanation:
Using the recursive formula with f(1) = - 3 , then
f(2) = - 2 + 3f(1) = - 2 + 3(- 3) = - 2 - 9 = - 11
f(3) = - 2 + 3f(2) = - 2 + 3(- 11) = - 2 - 33 = - 35
f(4) = - 2 + 3f(3) = - 2 + 3(- 35) = - 2 - 105 = - 107
Thus the first four terms are
- 3, - 11, - 35, - 107
What is the solution of the equation 2/3 + 5x/3= 9 ?
Answer:
x=5
Step-by-step explanation:
multipy both sides of the equation by 3 to remove the denominator becomes
2+5x=27
subtract 2 from both sides since it's positive
5x=25
divide 5 from both sides
x=5

Mike and Teegan each measured the volume of the 16-ounce bottle three times. They recorded their measurements as shown. Mike: 16.4 oz, 15.2 oz, 15.8 oz Teegan: 16.34 oz, 16.59 oz, 15.13 oz Which statement is true? Mike's measurements are more precise and more accurate. Teegan's measurements are more precise and more accurate. Mike's measurements are more precise, but Teegan's measurements are more accurate. Mike's measurements are more accurate, but Teegan's measurements are more precise.
Answer:
The correct option is;
Mike's measurement are more precise and more accurate
Step-by-step explanation:
The given information are;
The mass of the measured bottle = 16-ounce
The record of the measurements made by Mike are;
16.4 oz
15.2 oz
15.8 oz
The record of the measurements made by Teegan are;
16.34 oz
16.59 oz
15.13 oz
From the two measurements, we have;
The precision of a measurement depends on how close the values of the measurement are to one another, therefore, we have;
For Mike, the precision is given as follows
16.4 - 15.2 = 1.2
16.4 - 15.8 = 0.6
15.8 - 15.2 = 0.6
Total difference = 1.2 + 0.6 + 0.6 = 2.4
For Teegan , the precision is given as follows
16.59 - 16.34 = 0.25
16.59 - 15.13 = 1.46
16.34 - 15.13 = 1.21
Total difference = 0.25 + 1.46 + 1.21 = 2.92
Therefore, Mike's measurements are more precise than Teegan's measurements
The accuracy of the measurement is the amount of closeness the measurements are to a given value
In the question, the given value is 16-ounces of the volume of the bottle
Therefore, by the mean absolute deviation from the 16-ounce of the bottle, we have;
For Mike;
[tex]Mean \ absolute \ deviation = \dfrac{\left | 16.4 - 16 \right | + \left | 15.2 - 16 \right | + \left | 15.8 - 16 \right | }{3} = 0.533[/tex]
For Teegan, we have;
[tex]Mean \ absolute \ deviation = \dfrac{\left | 16.34 - 16 \right | + \left | 16.59 - 16 \right | + \left | 15.13 - 16 \right | }{3} = 0.6[/tex]
Therefore, Mike's measurement is more accurate than Teegan's measurement.
Which gives;
Mike's measurement are more precise and more accurate.
Answer:
Mike’s measurements are more accurate, but Teegan’s measurements are more precise.

If M is the midpoint of XY, find the coordinates of X if M(-3, -1) and Y(-8, 6).
Answer
X(2, -8)
Step-by-step explanation:
-8 and -3 have a distance of 5
6 and -1 have a distance of 7
-3 + 5 = 2
-1-7 = -8
(2, -8) is the answer
The coordinates of the Point X will be - X(2, -8).
The Mid - point of the line segment is at coordinates - M(- 7.5, 0.5)
We have two coordinate points - M(-3, -1) and Y(-8, 6)
We have to find the coordinates of the Point X.
What is Mid - Point Theorem?It states that a line with endpoint coordinates as - [x(1), y(1)] and
[x(2), y(2)] has its mid - point at the coordinates -
[tex](X_{m} ,Y_{m}) =[/tex] [tex](\frac{x(1) + x(2) }{2}, \frac{y(1) + y(2)}{2} )[/tex]
According to question, we have -
coordinates of Mid - Point = (- 3, -1)
coordinates of Y = (- 8, 6)
Using the Mid - Point formula -
-3 x 2 = x(1) - 8
x(1) = - 6 + 8
x(1) = 2
and
-1 x 2 = y(1) + 6
y(1) = -2 - 6
y(1) = - 8
Hence, the coordinates of the point X will be - X(2, -8)

A vendor at a baseball game sells boxes of popcorn and bags of pretzels.
• A customer buys 2 boxes of popcorn and 1 bag of pretzels for $6.75.
• Another customer buys 1 box of popcorn and 2 bags of pretzels for $6.00.
Each bag of pretzels costs $
Answer:
Each bag of pretzels costs $1.75
Step-by-step explanation:
Let the cost of 1 box of popcorn be $x
Let the cost of 1 bag of pretzel be $y
_______________________________________
A customer buys 2 boxes of popcorn and 1 bag of pretzels for $6.75.
cost of 2 box of popcorn =2*$x = $2x
sum of cost 2 boxes of popcorn and 1 bag of pretzels in terms of x and y
2x + y = 6.75 equation A
__________________________________
Another customer buys 1 box of popcorn and 2 bags of pretzels for $6.00
cost of 2 box of pretzel =2*$y = $2y
sum of cost of 1 box of popcorn and 2 bags of pretzels in terms of x and y
x + 2y = 6 equation B
x = 6 - 2y
substituting this value of x in equation A
2(6 - 2y) + y = 6.75
=> 12 - 4y + y = 6.75
=> -3y = 6.75 - 12 = -5.25
=> y = -5.25/-3 = 1.75
Thus, Each bag of pretzels costs $1.75
