Answer:
x = 35
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2/7*x-(10)=0
2

Subtracting a whole from a fraction
Rewrite the whole as a fraction using 7 as the denominator :
10 10 • 7
10 = —— = ——————
1 7
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
2x - (10 • 7) 2x - 70
————————————— = ———————
7 7
Pull out like factors :
2x - 70 = 2 • (x - 35)
2 • (x - 35)
———————————— = 0
7
When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
2•(x-35)
———————— • 7 = 0 • 7
7
Now, on the left hand side, the 7 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
2 • (x-35) = 0
Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : x-35 = 0
Add 35 to both sides of the equation :
x = 35

Pam wants to put a banner across her garage door to congratulate her son on his college graduation. The garage door is 9 feet high and 12 feet wide. How many feet long should the banner be to fit the garage door?
9514 1404 393
Answer:
15 feet
Step-by-step explanation:
The diagonal of a 9 ft by 12 ft rectangle is given by the Pythagorean theorem as ...
d = √(9² +12²) = √225
d = 15 . . . . feet
The banner should be 15 feet long to match the length of the door diagonal.

The outside dimensions of a rectangular cooler WITHOUT its lid is 26 inches by 14 inches, with a height of 16 inches. The cooler is 2 inches thick. What is the volume inside the cooler
Answer:
3080 square inches
Step-by-step explanation:
I like to draw things out. So I drew this cooler out, with the dimensions of 26x14x16. It the cooler is 2 inches thick, I need to remove 2 inches from each side of the cooler. So I took 4 inches off of the 26 and the 14 so the length and width become 22 and 10 respectively. Then I took 2 inches off the bottom of the cooler so the 16 became 14. This gives me the new dimensions of 14x22x10.

Triangle DEF has an angle D measuring 25 degrees and an angle E
measuring 50 degrees.
What is the measure of angle F, in degrees?
Answer:
The angle F of the triangle DEF measures 105 degrees.
Step-by-step explanation:
Given that triangle DEF has an angle D measuring 25 degrees and an angle E measuring 50 degrees, to determine what is the measure of angle F in degrees, knowing that the sum of the internal angles of every triangle gives a total of 180 degrees, we must perform the following calculation:
180 - 50 - 25 = F
130 - 25 = F
105 = F
Therefore, the angle F of the triangle DEF measures 105 degrees.
What angle maximizes the area of the triangle below?
Answer:
90°
Step-by-step explanation:
Area of triangle with sides a and b and included angle Θ:
A = (1/2)ab * sin Θ
dA/dx = (1/2)ab cos Θ
(1/2)ab cos Θ = 0
cos Θ = 0
Θ = 90°

you have a spinner divided into 5 equal sections each section is number with a number 1 through 5 theoretically what is the probability of spinning and landing on a five
Answer:
20%
Step-by-step explanation:
1/5 = 20/100 = 20%
Answer:
1/5
Step-by-step explanation:
probability- number of favorable outcomes/ number of total outcomes
in this question,
number of favorable outcomes is 1.
and, the number of total outcomes is 5.
so, probability of spinning and landing on 5 is 1/5.

A monitor measures 10.6 inches by 16.8 what is the length of the diagonal
Step-by-step explanation:
We will use pythagoras' Theorem for this question
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
where c is the longest side (in this case, the diagonal)
a and b are the 2nd and 3rd longest side (interchangeable)
given a = 10.6, b = 16.8,
[tex] {c}^{2} = {10.6}^{2} + {16.8}^{2} \\ {c}^{2} = 112.36 + 282.24 \\ {c}^{2} = 394.6 \\ c = \sqrt{394.6} \\ = \frac{ \sqrt{9865} }{5} inches[/tex]
