Answer:
20km = 6.5km + w
w = 20 km - 6.5 km
w = 13.5 km
Step-by-step explanation:
because 20km = present week
last week = w
The sentence says [Present Week] = 6.5 km MORE than [Last Week]
MORE mean "+"
[Present Week] = 6.5 km + [Last Week]
20 = 6.5 km + [Last Week]
20 = 6.5 + w
w = 20 - 6.5 = 13.5 km
Answer:
Step-by-step explanation:
x^2 and -x^2 would cancel
and then it would be -7 = 1
it would be no solution
but I don't know, someone can prove me wrong I may have a lapse in my algebra at the moment
Answer:
see below
Step-by-step explanation:
a x (b+c) = a x b + a x c
Let A= -35 , B = 10 , C= -5
-35 * ( 10 -5) = -35 *10 + -35 * -5
-35 *(5) = -350 + 175
-175 = -175

Show an attachment so we can see what you mean.
Step-by-step explanation:
Using the law of sins:
side a / sin (angle A) = side b / sin(Angle B)
Side a is opposite angle A, so from the picture we know side a = 50, angle A is 58 degrees and angle B is 48 degrees.
replace those values in the formula we get:
50 / sin(58) = b/ sin(48)
so now we can cross multiply the 2 fractions to get:
50 * sin(48) = b*sin(58)
to get b by itself, divide both sides by sin(58) to get:
b = (50*sin(48)) / sin(58)
b = 43.82
You may need to round the answer as needed.
