Answer:
Step-by-step explanation:
4 + 9x + 3 = 29 - 2x
9x + 7 = 29 - 2x
11x = 22
x = 2
Answer:
You were close; you don’t have to add 3x to the right side though.
We’re given 2y= -3x + 6
Step one: divide both sides by 2
y= (-3/2)x + 3
Answer:
B. 0.5 and 0.2
C 2 and 3.2
Step-by-step explanation:
because anything lesser than the standard value of one is smaller.
because anything over the standard value of one is larger.
Answer:
The dimensions are 5 m by 20 m.
Step-by-step explanation:
The area = length * width = 100 m^2.
2 times the width + the length = 30 m.
So we have the equations:
wL = 100
2w + L = 30
From the first equation:
L = 100/w so substituting in the second equation, we have:
2w + 100/w = 30
Multiply through by w:
2w^2 + 100 = 30w
2w^2 - 30w + 100 = 0 Divide by 2:
w^2 - 15w + 50 = 0
(w - 5)(w - 10) =
w = 5 or 10m.
So L = 100/5 or 100/10
= 20 or 10.
As it is rectangular then w = 5 and L = 20.
Question
a number cube is rolled one time. what is the probability that it will land on 5?
Answer:
1 : 6
Step-by-step explanation:
the cube has 6 sides and 6 different numbers, so the probability is 1 : 6
