Answer:
W.
Step-by-step explanation:
SSS, or Side-Side-Side is used to prove two triangles similar
Figure W. is the only one that uses three side marks, all of the others use at least one angle to prove them similar.
When you multiply a decimal with a decimal, you just multiply like you would with whole numbers. Then, you count the numbers to the right of the decimal for both multiplicand an multiplier. If the equation was 8.374 x 1.234, then you would put the decimal 6 spots to the left of the product. For the first step of solving this is just multiply like and decimal is not there. The answer would be 10333516. Then you count the number right of the multiplicand and the multiplier. In total there is 6 numbers, so you put the decimal 6 spots to the right. The end result would be 10.333516. Hope this helped!
We can solve this system of equations using substitution.
2y + 2x = 8
Solve for x.
2x = -2y + 8
Divide all terms by 2.
x = -y + 4
Take the equation x = -y + 4 and substitute it into the second system of equation.
2y - 4x = 2
2y - 4(-y + 4) = 2
Simplify by distributing.
2y + 4y - 16 = 2
Combine like terms.
6y - 16 = 2
6y = 18
y = 3
Now that you know the numerical value of y, substitute y with 3 in both equations to find x.
1) 2y + 2x = 8
2(3) + 2x = 8
6 + 2x = 8
2x = 2
x = 1
2) 2y - 4x = 2
2(3) - 4x = 2
6 - 4x = 2
-4x = -4
x = 1
The value of x is 1, and the value of y is 3.
Solution: B) (1, 3)
Answer:
Sustitute the y-values into the equation.
For y=10,
2(10) + 3 (10 - 5)
20 + 3(5)
20+15
35
For y=57,
2(57) + 3 (57 - 5)
114 + 156
270
For y=35
2(35) + 3 (35 - 5)
70 + 3(30)
70 + 90
160
