Answer:
its 3.5
Step-by-step explanation:
since we need to replace x with 6 the equation is now 3(6) + 8y = -10.
next i would multiply 3&6 to 18 then subtract 8y to the other side like this
18 + 8y = -10
- 8y -8y
18= -10 -8y
then i would add -10 to 18 on that side
18= -10 -8y
+10 +10
28 = 8y
then i divided
3.5 is my answer

Algebra can be used to solve a random number problem by considering order of operations.
Step-by-step explanation:
Algebra is one of the broad parts of mathematics, together with number theory, geometry, and mathematical analysis. It is used to represent the letters and symbols than numbers and quantities.
Algebra is of two types
i.) Elementary algebra , ii.) Abstract algebra
Elementary algebra is used for any study and their applications.
Abstract algebra is used for advanced mathematics by professionals.
The order of operations in algebra means solving first for exponents or roots, then multiplication, division, addition, and last for subtraction. The steps for the order of operations also require attention to mathematical grouping symbols, such as parentheses and brackets.
Answer:
a. 20.5
Step-by-step explanation:
because this will form a right triangle we can use tan (opposite over adjacent) so an equation we could set up would be tan(70)=25/x
therefore we can just solve the equation which would give us 20.45. so if we round it the answer would be a
