Step-by-step explanation:
the fractions would cancel out and leave negative 1
then -1 x -1 = 1
Answer:
the answer is A
Step-by-step explanation:
-1 × (- 8/7) × 7/8 ( multiplying an even number of negative terms makes the product positive)
1 × 8/7 × 7/8 ( any number that is multiplied by 1 stays the same)
8/7 × 7/8 ( reduce the numbers with the greatest common factor 8 )
and then we have 1/7 × 1/7 (reduce the numbers with the greatest common factor 7)
and we have 1 , good luck

A tetrahedron is a pyramid with a triangular base. Find the volume of the tetrahedron.
L = 3 in W = 4 in H = 11 in
Answers
Answer:
Tetrahedron generally known as triangular pyramid consists of 4 triangular faces, 6 edges and 4 vertices. The base of the tetrahedron is a triangle. All the vertices have the same atom that is bonded to the central metal atom which lies in the centre of the tetrahedron. We take as an example to see how the atoms actually bond in tetrahedron. It is quite visible from the image that 4 O-atoms lies on all the 4 vertices and 1 Si-atom lie in the centre.

A triangles angles will always add up to 180°.
Therefore, we can add these equations to get 180° and then find x.
(4x-2) + (7x-2) + (5x-8) = 180°
Now we simply the equation by combining like terms.
16x -12 = 180°
Now we can solve for x. ^w^
16x -12 = 180°
+12 +12
~~~~~~~~~~~~~
16x = 192
/16 /16
~~~~~~~~~~~~~
x = 12
Yay! We found x. Now we plug it into each equation:
~ 4x-2
4(12)-2
48-2
46°
~ 7x-2
7(12)-2
84-2
82°
~ 5x-8
5(12)-8
60-8
52°
It’s always a good idea to check if these angles add up properly to 180°.
46° + 82° + 52° = 180°
Congrats! We are all done ^u^

6x + y = 15
-7x - 2y = -10
Answers
Answer: x = 4 y=-9
Step-by-step explanation:
Answer:
x = 4
y = -9
Step-by-step explanation:
Isolate a variable from one of the equations ( I chose the first equations cuz it's easy): 6x + y = 15 will be y = 15 - 6x
Substitute the above equation in the place of y in the second equations:
-7x -2(15 - 6x) = -10
-7x -30 + 12x = -10
-30 + 5x = -10
5x = 20
x = 4
To find y-value, substitute the x-value gotten in any equation:
y = 15 - 6(4)
y = 15 - 24
y = -9
Hope this helps!

Solve the system of equations by substitution.
-8x+2y=4
y=4x+2
Answers
Answer:
the answer by substitution would be y = 4x+2
Correct answer: Infinite solution because 2 = 2.
Set the first equation equal to y.
-8x + 2y = 4
+8x +8x
___________
2y = 8x + 4
__ ___ __
2 2 2
y = 4x + 2
At this step, you can choose any equation to substitute into the other equation. However, I'm going to substitute the new first equation with the second equation where y is. Solve for x.
y = 4x + 2
4x + 2 = 4x + 2
-4x -4x
____________
2 = 2
So, at this point, we know the system of equation does not have one solution. Thus, when the same number equals the same number, it is an infinite solution.
We can prove this by an online graphing tool. Insert the two equations onto the online graphing tool. If the lines appear to be on the same line, they have infinite solutions. Hope this helps :) Let me know if you have any questions related to this problem!

6(3)+21(4)=18+84=102
2(2(3)+7(4)=2(6+28)=12+56=102
5(6)x7(6)=30+42+72
6(5+7)=6(12)=72
14(10)+2=140+2=142
2(7(10)+1)=2(70+1)=2(71)=142
102+102+72+72+142+142=632
632 squared means 632x2 which is 1264.

What is Proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
Two ratios or fractions are equal when an equation or a declaration to that effect is utilised.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Sarah used 10 gallons of gasoline to drive 240 miles.
let in 324 miles, x gallons of Gasoline is used.
Now, using proportion we have
10 / 240 = x / 324
3240 = 240 x
x = 3240 / 240
x = 324 / 24
x = 13.5 miles
