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
A = L * W
A = 7 * 4
A = 28 sq ft....this is the area of her garden
and if each plant uses 1 sq ft, then there will be (30 - 28) = 2 plants leftover
Answer:
There is a slight problem with this question
Do numbers starting with "0" count as a digit position
I would say no, thus the answer is 4...
if you are allowed to use 0 then the answer is 8
in other words if the question was using only 4's and 1's then the answer would be 8

Answer:
C. you can not prove that the triangles are congruent
Step-by-step explanation:
- The answer can not be SAS becuase although the congruent angle is not in between the two congruent sides.
- It can not be AAS because only one angle is congruent.
- It can not be SSS because all three sides are not congruent.
