Answer:
(a) 150
(b) 384
(c) 84
(d) 261
(e ) 480
Step-by-step explanation:
(a)
Let 'a' be a number such that the half of his third is 25; i.e.
Hence, the number is 150.
(b)
Let 'b' be the number such that the quarter of his half is 48 i.e.
Hence the number is 384.
(c)
Let 'c' be the number such that the third quarter or, increased by 17 is 80.
Hence, the number is 84.
(d)
Let 'd' be the number such that its triplet, reduced by 28 is 755
Hence the number is 261.
(e
Let 'e' be the number such that double his third, increased by 80 is 400.
Hence, the value of the number is 480.
The difference in math means the result of subtracting one number from another.
m = Mai’s height
Therefore, the equation is:
Take two points to find the slope
Let;s take (1, -3) and (-3, -1)
Point slope formula is
m =
or
y₂-y₁ = m×(x₂-x₁) Which is the same thing
m =
=
It can be simplified:
=
Now we found the slope
Same formula:
y₂-y₁ = m × (x₂-x₁)
Substitute the point only (1, -3)
y₂-(-3) = × (x₂-1)
y₂ + 3 = × (x₂ - 1) (minus minus = plus)
The last option is the answer

Answer:
15.78 %
Step-by-step explanation:
It is given that,
Miguel made 80 on his Math test. He made 95 in last week's Math test.
We need to find the percent change on his scores. It can be calculated as follows :
So, there is a percent change of 15.78%.
