How do i solve things that dont make sense to me even though i do know but dont know
kirill [66]

Answer:

Just try to make it make sense to you.

Step-by-step explanation:

For instance, a + 1 = 5

a = 4

We know that we should switch the terms as when it comes to normal numbers ,10 + 1 = 11 , 10 = 11-1. Therefore, the only trick is not to memorise, but try to understand the logic behind it. Hope this helps in some way???

the line Plus shows the differences some students jumped during a field day competition what fraction of the students jumped 5 1
MissTica

Answer:

⅛

Step-by-step explanation:

Each mark (x) on the plot presents the distance that each student jumped.

There are 24 marks there, so it means there is a total of 24 students whose distance jumped were recorded.

Number of students that jumped 5½ ft = 3

Fraction of the students that jumped 5½ ft = no of students that jumped 5½ ft / total number of students

= 3/24

Simplify/reduce the fraction

= 1/8

y - b = mx...now divide both sides by x
(y - b) / x = m
