X= 9/2, 15/2
decimal form: 4.5,-7.5
mixed number form: 4 1/2, -7 1/2
Answer:
21.6 or 22
Step-by-step explanation:
Triangles have same angles. This means that they are proportion.
50/27 = 40/x
when you cross multiply to solve x, 50x = 1080
so x = 21.6
If you have to nearest whole number, it will be 22
Answer:
Exponents
Step-by-step explanation:
exponents are basic short cut to write numbers like 100, 1000, 10000, 1000000 and so on.
Exponents can also be defined as 10 raised to a power x whether positive or negative

They are mostly used in expressing units in standard form.
<h3>examples of basic positive exponents</h3>




basically the power represent the the number of zeroes after the 1.
<h3>examples of basic negative exponents</h3>




in negative exponents the power represents the number of zeroes before the 1. including the 0 behind the decimal point.
this is the basic lay down of how exponent work but one more quick example for maximum understanding
<h3>quick example</h3>




hope you grasp the concept involved in multiplication with other terms.
cheers
I believe you combine the first and last terms first because they have the same denominator
Answer:
y = 13x
Step-by-step explanation:
gradient = 13
x = 0
y = 0
so
= 13
cross multiply and you get
y = 13x
