Answer:
x = 4
Step-by-step explanation:
8x - 9 = 6x - 1
Bring variables to the left side, whereas numbers to the right.
8x - 6x = - 1 + 9
2x = 8
x = 8 / 2
x = 4

Answer: 48
Step-by-step explanation:
We have to write a system of equations:
The difference between two numbers is 29. Difference means one number (y) minus another number (x) equals 29.
y-x =29
If five times the smaller ( 5 times x , x is the smaller number because is the number to subtract) is subtracted from twice the larger, (2y)
The result will be one
2y-5x =1
Now, we have to multiply the first equation by 2, and subtract the second equation to the first one:
2y -2x = 58
-
2y-5x =1
__________
3x =57
Solve for x:
x =57/3 =19
Replacing the value of x on any equation:
y-x =29
y-19 =29
y = 29+19 = 48
48 (y)> 19(x)

Answer:
See below.
Step-by-step explanation:
5a)
In an isosceles triangle, the angles opposite the congruent sides are congruent.
m<A = 40 deg
m<B = 40 deg
m<A + m<B + m<C = 180
40 + 40 + m<C = 180
m<C = 100 deg
5b)
In a right triangle, one angle is a right angle.
m<A = 40 deg
m<B = 90 deg
m<A + m<B + m<C = 180
40 + 90 + m<C = 180
m<C = 50 deg
Answer:
m= -1/3
Step-by-step explanation:
slope is rise/run or change in y/change in x
i pick out point (9,0) to (6,1)
the increase in y of this triangle is 1 and increase in x is 3
note that this line will have a negative slope as it goes downwards from left to right instead of upwards
hence m= rise/run= -1/3
