Answer:
RXS=48
Step-by-step explanation:
According to the figure,
RXQ+QXS=RXS
or,8x-1+3x+5=5x+28
or,8x+3x-5x=28+1-5
or,6x=24
or, x=24/6
or,x=4
Then,
RXS=5x+28
=5×4+28
=20+28
=48
Answer: x=-3
Step-by-step explanation:
5(x−8)=−55
x-8=-55/5
x-8=-11
x=-11+8
x=-3
2.5 and 2.500 are both equivalent to 2.50
We observe that the relationship between the variables is linear.
Therefore, we look for an equation of the form:
Where,
m: slope of the line
b ': intersection with the y axis
a: independent variable
b: dependent variable
The value of b 'occurs when a = 0.
We have then:
(See table)
Then, the value of the slope is found using the following formula:
Substituting values:
Rewriting:
Thus, the linear equation is:
