solve using suitable property -2/3 + 5/7 + -8/9 + 3/14
Answer:
[tex]\dfrac{-79}{126}[/tex]
Step-by-step explanation:
The given expression is :
[tex]\dfrac{-2}{3}+\dfrac{5}{7}+\dfrac{-8}{9}+\dfrac{3}{14}[/tex]
The LCM of 3,7,9 and 14 is 126
So,
[tex]\dfrac{-2}{3}+\dfrac{5}{7}+\dfrac{-8}{9}+\dfrac{3}{14}=\dfrac{42(-2)+18(5)+14(-8)+9(3)}{126}\\\\=\dfrac{-79}{126}[/tex]
So, the value of the given expression is equal to [tex]\dfrac{-79}{126}[/tex].
Find the value of x such that the data set has the given mean. 98,122,104,115,107,x,102 x=(Type an integer or a decimal.)
Answer:
x = 66
Step-by-step explanation:
For a set of N numbers:
{x₁, x₂, ..., xₙ}
The mean can be calculated as:
[tex]M = \frac{x_1 + x_2 + ...+ x_n}{N}[/tex]
In this case we have the data set:
{98, 122, 104, 115, 107, x}
And I assume that we want to have the mean = 102.
So we have a set of 6 numbers, the mean of this set will be:
[tex]M = \frac{98 +122+104+115+107+x}{6} = 102[/tex]
We need to solve this equation for x.
If we multiply both sides by 6, we get:
(98 + 122 + 104 + 115 + 107 + x) = 102*6 = 612
546 + x = 612
x = 612 - 546 = 66
x = 66

Answer:
Option A is correct:
x + 4 < 12
Step-by-step explanation:
The sum of x and 4 means addition:
x + 4
less than 12 means <:
x + 4 <12
Have a nice day!
Answer: A.) x + 4 < 12
Step-by-step explanation: With the process of elimination, there would only be two possible answers: (A. x + 4 < 12 and C. 4x < 12) because in the problem, it says less than. Since, x and 4 cannot mean 4x since that means multiplication, the only available answer would be A. x + 4 < 12).
Monica found the volume of the prism below using the expression .
What errors did Monica make? Check all that apply.
She should have counted only 2 unit cubes instead of 4.
She should have counted 8 one-third cubes instead of only 4.
She should have found the total value of the one-third cubes by multiplying by instead of by .
Each fractional cube is worth instead of the that she used.
She cannot stack more than one layer of fractional cubes in a prism.
Answer:
See Explanation
Step-by-step explanation:
The expression and the dimension of the prism are not given.
So, I will just give a general expression.
The volume of a prism is:
[tex]Volume = Length * Width * Height[/tex]
Assume that:
[tex]Length = 2[/tex]
[tex]Width = 2[/tex]
[tex]Height = 1\frac{2}{3}[/tex]
See attachment
Monica's expression should be:
[tex]Volume = 2 * 2 * 1\frac{2}{3}[/tex]
And the solution will be:
[tex]Volume = 2 * 2 * \frac{5}{3}[/tex]
[tex]Volume = \frac{20}{3}[/tex]

Answer:
24 yd^2
Step-by-step explanation:
There's a large rectangle here, 4 yd wide and 8 yd long. The area of this large rectangle is 32 yd^2.
The smaller rectangle is 4 yd long and 2 yd wide, and so its area is 8 yd^2.
The area of the figure is thus 32 yd^2 - 8 yd^2, or 24 yd^2.

Step-by-step explanation:
Use this as a guide, SOH-CAH-TOA, O=opposite, A=adjacent(side) H=hypotenuse, as for the S,C,T, S=sin, C=cos, T=tan, we see that they gave us the angle needed to find the missing side(52). If you have a calculator (TI-84) set it at degree mode and proceed to pick the side. Its confusing hold up, ill draw it.

Find the measures of interior angles. Find a and B.
Answer:
A = 68
B = 44
C = 68
Step-by-step explanation:
find x:
68 + x + x - 24 = 180
2x + 44 = 180
180 - 44 = 136
136 / 2 = 68
x = 68

Bella brought stickers to give to 12 of her friends. Each friend received 4 stickers.
how many stickers did she bring to schoo
[tex] x \div 4 = 12[/tex]
Answer: The answer is x/4 = 12.
Step-by-step explanation: This is because in the problem it says "How many stickers did she bring to school" so you will have to divide x by 4 in order to get 12.

Thanks!!!
Answer:
9π units²
Step-by-step explanation:
To obtain an exact answer, use π, not an approximation such as 3.14.
A = πr² is the appropriate formula.
Here,
A = (3)^2·π units², or 9π units²

Violet drove 396 miles on 12 gallons of gas. At the same rate, how many miles can she drive on 16 gallons of gas?
Answer:
528 miles
Step-by-step explanation:
The unit of miles per gallon is 33
Use the 396/12 to find that
To find how much for 16 gallons multiply 16 by 33
16*33 = 528
On 16 gallons she can drive 528 miles
Violet drove a distance of 396 miles on 12 gallons of gas. which is determined by the given proportion.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
Given that she drove 396 miles on 12 gallons of gas.
Let the number of miles would be x can she drive on 16 gallons of gas.
According to the given question, we can write a proportion as
396 miles : 12 gallons = x miles : 16 gallons
396 / 12 = x / 16
Apply the cross-multiplication operation,
396 × 16 = 12x
12x = 6,336
x = 6,336 / 12
Apply the division operation,
x = 528
Therefore, she drove a distance of 396 miles on 12 gallons of gas.

Answer:
h = -9
Step-by-step explanation:
2(h + 3.5) = -11
2h + 7 = -11
subtract 7 from both sides of the equation:
2h = -18
divide both sides by 2:
h = -9
If the perimeter of a triangle is 8x + 6y, and two of the sides are 2x + 2y and 5x − y, which is the third side?
A.x + 5y
B. x + 4y
C. 5x + y
D. 2x + 2y
Answer:
A.x + 5y
Step-by-step explanation:
let 3rd side be z
P=2x+2y+5x-y+z=8x + 6y
7x+y+z=8x+6y
z=8x+6y-7x-y=x+5y (⇒ A)
