Answer:
BC=11
Step-by-step explanation:
we need to find BC
and we know that
AB= x+2
AC=13
BC=2x+11
A, B and C are collinear
that means that
AB+BC=AC
x+2+2x+11=13
3x+13=13
3x=0
x=0
so BC=2(0)+11
BC=11
Answer:
I don't know what the question is but...
Step-by-step explanation:
-2t+5-13= -2t-8
-2t+5+13=-2t+18
-2t+5*13= -2t+65
-2t+5/13= -26t-5/13
Answer:
(x-10)/4
Step-by-step explanation:
10 less than x means,
x - 10
and the divide by 4.
=> (x-10)/4
Answer:
(
b, 0 )
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Here m = -
and b = b , thus
y= -
x + b ← equation of line
The line crosses the x- axis when y = 0, substitute y = 0 into equation and solve for x, that is
-
x + b = 0 ( multiply through by 3 to clear the fraction )
- 5x + 3b = 0 ( subtract 3b from both sides )
- 5x = - 3b ( divide both sides by - 5 )
x =
b , thus
x- intercept = (
b, 0 )
Answer:
20 questions
Step-by-step explanation:
Well, 10% of 50 is 5, and 5 x 4 = 20. Another way is 50 x .4
