I somehow got -1(4/6)x=-5. Can someone provide a clear explanation on how to do this?

Answers

I have no idea how did you get this result but I can show you the method of elimination. I think that it is the easiest way to solve the system of equations.
2 x + 3 y =105
x + 2 y = 6 /*(-2) // We will multiply 2nd equation by -2. That is because we want to cancel out the x`s//
2 x + 3 y = 105
-2 x - 4 y = -12 // Then we will add down these equations/ and x`s will cancel out//
3 y - 4 y = 105 - 12
- y = 93
y = -93
We can also solve x:
x + 2 * (-93)=6
x - 186 = 6
x = 6 + 186
x = 192

Question 5Two similar triangles are shown in the diagram below, where
AABC - ADEF.
Based on the dimensions in the diagram, what is the
perimeter of AABC?
A-9 in.
B-10 in.
C-9.5 in.
D-10.5 in.

Answers

Answer:

Perimeter of ΔABC is 9.5 in.

Step-by-step explanation:

Given:

ΔABC $\sim$ ΔDEF

DE = 6 in.

EF = 5.25 in.

DF = 3 in.

AB = 4 in.

We need to find the Perimeter of ΔABC.

Solution:

First we will find the sides of ΔABC.

Now By Triangle similarity property which states that:

"When two triangles are similar the the ratio of their corresponding sides are equal."

From Above property we can say that;

$(AB)/(DE) =(BC)/(EF)=(AC)/(DF)\n\n(4)/(6)=(BC)/(5.25)=(AC)/(3)$

Now we will find BC and AC

$(4)/(6)=(BC)/(5.25)\n\nBC = (4*5.25)/(6)= 3.5 \ in$

Also;

$(4)/(6)=(AC)/(3)\n\nAC = (4*3)/(6) = 2 \ in$

Now In ΔABC

AB = 4 in

BC = 3.5 in

AC =2 in.

Now Perimeter of ΔABC can be calculated as sum of all sides.

Perimeter of ΔABC = AB +BC +AC = 4 + 3.5 + 2 = 9.5 in

Hence Perimeter of ΔABC is 9.5 in.

Which one of the following mathematical statements is true? A. 0 ÷ 28 = 0 B. 28 – 0 = 0 C. 28 ÷ 0 = 0 D. 28 0 = 0

Answers

The mathematical statemen that is true is the A. 0 divided by 28 eauals 0. In fact 0 divided by any number is 0. Remember that no matter how you divide 0 it cannot be any different than 0. Or imagine that division means to distribute a thing into several parts. So, if you distribute 0 things among 1 or 2 or 300 parts, the result is always 0.
