Answer:-5
Step-by-step explanation:
The quotient of 4.2 and a number is less than or equal to 21.
Insert y and you get
X=0
Then insert x and you get
Y=-5
The shapes are similar.
When two figures are similar, the ratios of the lengths of their corresponding sides are equal.
Therefore,
Simplify:
Cross multiply:
42(10+x) = 57x
420 + 42x = 57x
420 = 57x - 42x
420 = 15x
x = (420÷15)
x = 28
Answer:
5. 8/6x + 2
6. -4x - 2
7. y=3
