Subsitution
4x+y=210
minus 4x both sides
y=210-4x
sub 210-4x for y in other equation
3x+2(210-4x)=195
3x+420-8x=195
-5x+420=195
minus 420 both sides
-5x=-225
divide both sides by -5
x=45

y=210-4x
y=210-4(45)
y=210-180
y=30
x=45

Thw statement that's true for the function g is g(-13) = 20.
<h3>How to illustrate the information?</h3>
From the information given, the function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45.
In this case, g(-13) = 20. Here, x = -13 is in the domain and 20 is also in the range. Therefore, this is true for g.

To write this value simply write the first part of the value before the decimal point
Which is 34
Then since it says 12 hundredths, make sure to place them after the decimal place.
0.12 = 12 hundredths
34.12 would be the answer.
Answer:
The answer is 70.8
Step-by-step explanation:
You do 7x3 times 2 and then 3x2.6 and then 7x3 again. You add them all up and get 70.8
21 + 21 + 3.9 + 3.9 + 21 = 70.8
