Answer:
a) 1.892a
b.) 5.1x - 1.49y
1.) X = 0.36
2.) Y = 4.347
Car B went faster by 1.25 times
Step-by-step explanation:
a)2.15a+0.03∙(3.4a−12a)
Open the bracket
2.15a + 0.102a - 0.36a
2.252a - 0.36a
1.892a
b)3.27x+1.28y+1.83x−2.77y
Rearranged the algebraic expression above
3.27x + 1.83x + 1.28y - 2.77y
5.1x - 1.49y
1)22.5x−4.6=3.5
Collect the like term
22.5x = 8.1
X = 0.36
2)y÷2.3+5.69=7.58
Y/2.3 = 7.58 - 5.69
Y = 2.3 × 1.89
Y = 4.347
WORD PROBLEM: Car A went 60 km in 5/6 hours while car B went 54 km in 2/3 hours.
Which car was faster?
That's speed
Speed = distance/time
Speed A = 60 ÷ 5/6 = 72 km/h
Speed B = 54 ÷ 2/3 = 81 km/h
How many times faster?
5/6 ÷2/3
5/6 × 3/2
15/12
1.25 seconds faster

Her we know that Jacey wrote an equation to find an angle measure. The equation is as follows:

So, if the angle 360° is a central angle, that is, an angle between two radii in a circle, then:
<em>a: Represents the number of equal parts parts the circle is divided</em>
<em>b: Represents the measure of the central angle of each part</em>
For example, suppose you have a circle and want to divide it into six parts, then, the central angle of each part of the circle will measure 60 degrees as indicated in the figure below.
It Would Be B. $1.90. Your Welcome :)
