Multiply the second equation by 3, so 4x-y=6 becomes 12x-3y=18.
x + 3y = -5
+ (12x-3y = 18)
______________
13x = 13
So x = 1
Plug x = 1 into any of these, such as 1 + 3y = -5, which becomes 3y = -6, and then y = -2.
x = 1
y = -2
Answer:
The similarity ratio is 2 to 1
Step-by-step explanation:
Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal
Now, let us use the angle markings
We have it that;
RP/QR = VW/VX
4/8 = 1/2
1/2 = 1/2
2 meters in centimeters would equal up to 200 centimeters. Meters and Centimeters are about 1 in the same. Centi meaning 100 is just a smaller measurement.
Answer:
sure ill make one for you lol
For the first, simply plug in the value of x given (x = 2) into the equation: 
So, 8 would be your answer.
For the second, the sum of x and 2 would be expressed as x + 2. Twice this sum would be written as 2(x+2). Finally, 8 less than twice that sum would be written as 2(x+2) - 8, which would be your expression.
For the last question, the coefficient refers to the number directly in front of the variable, x. So you need only to check what the x would simplify to in each equation and look for the expression where x has no coefficient (i.e., its coefficient is 1). For Hunter, the coefficient would be 15 (5 × 3x = 15x); for Michael, the coefficient would be 11 (6x + 5x = 11x); for Nate, the coefficient would be 1 (x = 1x); and for Spencer, the coefficient would be 2 (2x = 2x). Thus, Nate's expression has a coefficient of 1 when simplified.
