X/4 + 9 = -13 help please

Subtract  

from both sides of the equation

from both sides of the equation

Multiply all terms by the same value to eliminate fraction denominators

x= -88

Step-by-step explanation:

We move all terms to the left:

x/4+9- (-13)=0

Then we add all the numbers together, and all the variables:

x/4+22=0

We multiply all the terms by the denominator:

x+22*4=0

We all all the numbers together, and all the variables:

x+88=0

We move all the terms containing x to the left, all other terms to the right:

x= -88

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
