Answer:
m/0.1
Step-by-step explanation:
--
we want to find it
-----
10%*x=m
OF means multiply
IT is any variable
IS is equal
10%*x=m
0.1*x=m
x=m/0.1 IN THE ANSWER DO NOT INCLUDE x
X = Tessa's money
b = The book
m = The magazine
x35 - (b7 + m5) = x23
Answer:
25w^14

Answer:
b = 0
Step-by-step explanation:
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - 2x + 17 is in this form with slope m = - 2
• Parallel lines have equal slopes, hence
slope of line through the 2 points is - 2
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (b, 7)
m =
=
, hence
= - 2 ( cross- multiply )
- 2(b - 2) = 4
- 2b + 4 = 4 ( subtract 4 from both sides )
- 2b = 0 ⇒ b = 0
