if a =2 and b =3 then that would mean (2)(3)=(3)(2) so 2*3=3*2 and 2*3=6 and 3*2=6 so yes (2)(3)=(3)(2) or ab=ba
hope this helps
Answer:
ML = 7.5
Step-by-step explanation:
The ratios are the same for both lines.
The one at the top has a 8:10 ratio and the one below has a 6:ML ratio
Convert to fractions and find the value of ML:
8/10 = 6/ML
8*ML= 6*10
ML= 60/8 = 7.5
<span>The question is asking for the total of 36, 78, 198, 475 and 620. The correct option is B, that is, 1,407. Total refers to summation of a set of number, thus if the given numbers are added together, the sum total will be 1, 407. That is, 36 + 78 +198+475 + 620 =1, 407. Other words that can be used in place of total are: summation, addition or plus.</span>
Y = mx + b is the format for this equation, where <em>m</em> is the slope and <em>b</em> is the y-intercept. with that information, (-1) would be your slope, taking the assumed coefficient of 1 from the x, and the y-intercept is 5.
X= width of the path.
we can suggest this equation:
(20+2x)(28+2x)=1584
we solve this equation:
(20+2x)(28+2x)=1584
560+40x+56x+4x²=1584
4x²+96x-1024=0
4/4x²+96/4x-1024/4=0/4
x²+24x-256=0
We solve this square equation:
x=[-24⁺₋√(576+1024)]/2=(-24⁺₋40)/2
we have two solutions:
x₁=(-24-40)/2=-32 this solution is not valid.
x₂=(-24+40)/2=8
Answer: the width of the path is 8 m.
