(3x + 5)° + (10x - 7)° = 180°
13x + (-2) = 180
13x = 180 + 2
13x = 182
x = 14
∠QRT = 3 * 14 + 5 = 42 + 5 = 47°
∠TRS = 10 * 14 - 7 = 140 - 7 = 133°

Answer:
x = 1.02.
Step-by-step explanation:
The x is a factor worked out from the annual interest written as a decimal fraction.
So we have 2% = 2/100 = 0.02.
The amount at the end of the first year is $100 + 0.02*100
= $100* 1.02, and in the second year it will be $100* 1.02^t where t = 2 and so on.
So we see that x in the given expression is 1.02.
-56
Explain 9x7 is 56 then you add a negative. Please thanks and brainliest if correct!
Answer:
kk ill save ya from the scary question
the answer is B
Because the original picture is 16 by 20...but the scaled down picture is 4 by 5. Multiply 16 and 20 respectively by 1/4, and you get the scaled version that is 4 by 5
