Answer:
x,y =3,-4
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = 2x - 10
// Plug this in for variable y in equation [2]
[2] 3x - 2•(2x-10) = 17
[2] -x = -3
// Solve equation [2] for the variable x
[2] x = 3
// By now we know this much :
x = 3
y = 2x-10
// Use the x value to solve for y
y = 2(3)-10 = -4

( vertical opposite angles )
Hence, STW = 115°
Simplify the expression. 7d + 3 - 2d
Answer:
5d+3
Step-by-step explanation:
just as you combine regular numbers you can combine terms that have the same variable raised to the same exponent, and 7d-2d=5d. So the equation simplifies to 5d+3
Find the perimeter and area of a rectangle of cardboard measuring 18.7 cm by 18.5 cm
Answer:
74.4cm
Step-by-step explanation:
Perimeter is L + L + W + W
or 2L +2W
so 2(18.7) + 2(18.5) = 74.4 cm

CAN SOMEONE ANSWER THIS PLEASE AND RHANK YOU!
Answer:
1/9?
Step-by-step explanation:
Find the sine, cosine, and tangent of angle A. (fraction as in simplest form please.)
Answer:
SinA=3/5
CosA=4/5
TanA=3/4
Step-by-step explanation:
first we have to find what side length bc is using the Pythagorean triple formula a^2+b^2=c^2 or c^2-b^2=a^2
20^2-16^2=144 the square root of 144 is 12 so side length bc=12
so sin is opposite/hypotenuse
the opposite of angle a is 12 and the hypotenuse is 20 so sinA is 12/20 or 3/5
cos is adjacent/hypotenuse
the adjacent of angle a is 16 and the hypotenuse is 20 so cosA is 16/20 or 4/5
tan is the opposite/adjacent
the opposite of angle a is 12 and the adjacent is 16 so tanA is 12/16 or 3/4

Answer:
a = 6
Step-by-step explanation:
120 = 3 + 3(7a - 3) (by PEDMAS, expand parentheses first by distributive property)
120 = 3 + 7a(3) - 3(3)
120 = 3 + 21a - 9
120 = 21a - 6 (add 6 to both sides and rearrange)
21a = 120 + 6
21a = 126 (divide both sides by 21)
a = 126/21
a = 6
Step-by-step explanation:
120-(3+3*(7*a-3))=0
Step by step solution :

Equations which are never true:
4.1 Solve : -21 = 0
This equation has no solution.
A a non-zero constant never equals zero.

Add 6 to both sides of the equation :
a = 6
One solution was found :
a = 6

Answer:
1. Well, to cross multiply them you multiply the numerator in the first fraction times the denominator in the second fraction, then you write that number down. ... The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater.
2. Cross multiplying fractions to find a missing numerator or denominator for equivalent fractions works because it is a shortcut for rearranging to isolate the variable.

The first night in a hotel costs 40 dollars. All additional nights cost 27 dollars. How many nights did we stay
at this hotel if the total bill was 148 dollars?
Answer:
5
Step-by-step explanation:
First, you would want to subtract the first nights cost from the bill, which you would get 108. And then you would want to divide 108 by how much it costs to stay additional night, so 108 divided by 27 = 4. But you have to remember to add the first night you stayed so it would be 5. I hope this helps :)
Answer:
4 nights
Step-by-step explanation:
148-40=108
108÷27=4
So, you spent 4 nights at the hotel.

2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY
Answer:
x=2
Step-by-step explanation:
Simplify both sides of the equation.
2x−1−(−x + 3)=6−2x
(Distribute the Negative Sign)
2x−1 + −1(−x + 3)=6−2x
2x + −1 + −1(−x) + (−1)(3)=6−2x
2x + −1 + x + −3=6−2x
2x + −1 + x + −3=6 + −2x
(Combine Like Terms)
(2x + x) + (−1 + −3)=−2x+6
3x + −4=−2x + 6
3x−4=−2x + 6
Add 2x to both sides.
3x−4 + 2x=−2x + 6 + 2x
5x−4=6
Add 4 to both sides.
5x−4 + 4=6 + 4
5x=10
Divide both sides by 5.
5x/5=10/5
x=2
