Answer:
the answer is 36.4
Step-by-step explanation:
you have to multiply it by 4 so it it will look like this 9.1*4=36.4
Answer:
For the first one, R would be = -3/5
In the decimal form that would be -0.6
For the second one, K = 2/19
In the decimal form, it would be 0.10526315
…
Step-by-step explanation:
The best possible first step would be to multiply equation one by 4 and equation by 5 that would eliminate the y and allow you to solve for x.
In essence, 4 × (3x + 5y = 1) eq1
5 × (2x + 4y = -4) eq2
thus giving rise to 12x + 20y = 4 eq1 × 4
10x +20y = -20 eq2 × 5
You can then just subtract one equation from the other
For example, (12x + 20y = 4) - ( 10x +20y = -20 )
12x - 10x + 20y - 20y = 4 - (-20)
2x = 24
x = 12
Answer:
- (a-2)(3a-5)
- (b-3)(5b-17)
Step-by-step explanation:
Recognize that b-a = -(a-b). (Reversing the order of a difference changes its sign.)
1. 3(a-2)² -(2-a) = 3(a-2)² +(a-2) = (a-2)(3(a-2) +1)
... = (a -2)(3a -5)
2. 2(3-b) +5(b-3)² = (b -3)(-2 +5(b -3))
... = (b -3)(5b -17)
Answer:
let the number of ride ticket be x and that of the food ticket be y
x+y=32
1.50x+3.25y=90
y=32-x
1.50x+3.25(32-y)=90
1.50x+104-3.25y=90
-1.75x=90-104
-1.75x=-14
x=14/1.75
x=8
y=32-x
y=32-8=16
I would appreciate if my answer is chosen as a brainliest answer
