-10x + 1 + 7x =37
-10x + 7x = 37 - 1
-2x = 36
X = 36 / -2
X = -18
Answer is x = -18
I think this is the answer

Answer:
He caught 392 fish last month.
Step-by-step explanation:
If you do how many fish (28) he caught each time multiplied by how many times, you get 14. So do 14x28=392 fish last month.
Answer:
8(a+4)= 8a + 32
Step-by-step explanation:
Answer:
4 Hours
Step-by-step explanation:
Since the equation is:
y = 9x + 16
You have to find x
This is the logical way:
52-16 = 36 because thats the starting fee
So 36 divided by 9 equals 4
You do that because 9 is the charge per hr
So he rented it for 4 hours.
Hope this helps:)
Correct question is;
Type the correct answer in the box bellow: If cos x = sin(20 + x)° and 0° < x < 90°, the value of x is ...........
Answer:
x = 35°
Step-by-step explanation:
We are told that;
cos x = sin(20 + x)°
and 0° < x < 90°
From trigonometric identities, we know that;
cos x = sin (90 - x)
Applying to our question gives;
sin (90 - x) = sin (20 + x)°
Comparing both sides, we have;
90 - x = 20 + x
Rearranging;
90 - 20 = x + x
70 = 2x
x = 70/2
x = 35°
