Answer:

Step-by-step explanation:
The standard form of a linear equation is
.
The given line has equation:

This is the point-slope form of the given line.
To find the standard form, we clear the fraction

We expand the parenthesis now to get:

We group the variables on the LHS and the constants on the RHS.


Multiply through by -1

This is of the form:
.
Answer:
x=3 MT=36 MH=18
Step-by-step explanation:
The two triangles are the same, so 7x+8=10x-1
3x=9
x=3
MT=12x3=36
MH=36/2=18
Answer:

Step-by-step explanation:
Answer:
8 years
Step-by-step explanation:
Let age of father be f
age of John be j
age of Alice be a
John's father is 5 times as old as John. We can write:
f = 5j
John is twice as old as Alice. We can write:
j = 2a
or
a = j/2
SUM OF ALL OF THEIR AGES (after 2 years) will be 58. We can write:
f+2 + j+2 + a+2 = 58
This becomes:
f + j + a + 6 = 58
f + j + a = 52
Now, we replace third equation with the first two (in bold) and get:

So John is 8 years old
Answer:
