Step-by-step explanation:
Answer:y is the variable
Step-by-step explanation:a variable is a letter in an algebraic equation or expression
Let the no. of green marbles be x
no of blue marbles = 2x
no of red marbles = 3*2x = 6x
total marbles = 765
so, x+2x+6x = 765
or, x = 765/9 = 85
no of red marbles = 6*85 = 510
Answer: -5

Answer:
<h3>
m∠UVT = 97°</h3>
Step-by-step explanation:
Given m∠WVU = 169°, m∠WVT = (2x + 20)° and m∠UVT = (3x + 19)°, according to the diagram shown, it is seen that;
m∠WVU = m∠WVT +m∠UVT
Substitute the given parameters into the function as shown;
(2x + 20)°+(3x + 19)° = 169
collect like terms
2x+3x+20+19 = 169
5x+39 = 169
5x = 169-39
5x = 130
x = 130/5
x = 26°
Since m∠UVT = 3x+19, substitute x = 26 into the function
m∠UVT = 3(26)+ 19
m∠UVT = 78+19
m∠UVT = 97°
