Yes most likely a variable square can be combined with a variable I believe
Answer:
x = 25
Angle B = 65 degrees
Angle C = 50 degrees
Step-by-step explanation:
All triangles will add up to 180 degrees.
65 + 3x - 10 + 2x = 180
Combine like terms
55 + 5x = 180
Subtract both sides by 55
5x = 125
Divide both sides by 5
x = 25
Plug in the value for x in angle B:
3(25) - 10
75 - 10
65
Do the same for angle C:
2(25)
50
Check your work:
65 + 65 + 50 = 180
180 = 180
Correct
Answer:
Step-by-step explanation:
Subtract 15 from both sides of the equation.
Answer:
If the first number is x and y is the second number
x = 11
y = 18
Step-by-step explanation:
If x is the first number and y is the second number then:
x + 7 = y
The sum of the two numbers is expressed as:
x + y = 29
In order to find what the two numbers are, use what you know. According to the first equation, y equals the first number(x) plus 7, so you can substitute that for the y in the second equation
x + y = 29
x + (x + 7) = 29
2x + 7 = 29
2x + 7 - 7 = 29 - 7
2x/2 = 22/2
That means x equals 11
Now that x is known, you can find the value for y. The second number(y) is 7 more than than the first number(x) so that means x + 7 = y
11 + 7 = y
y = 18
I sure its B i might be wrong tho
