That isn’t right I don’t think, if a was 47 then it would be wayyyy bigger of a number. You are finding how 7a-2 is 47. First add 2 to both sides making it 7a=49
7 times what is 49?
That is a
What is the equation, it’s hard to understand
You can use the percentage such as 20% off, make it 0.20 times the discounted price. Then add that into the discounted price.
3(3x9)
3x3=9
3x9=27
9+27=36
Answer:
√2' = t
Step-by-step explanation:
1 1/2s = 3/5t^2 + 1/3u^2; substitute known values
1 1/2 • 28 = 3/5 • t^2 + 1/3 • -6^2; simplify
42 = 3 • t^2 ÷ 5 + 1/3 • 36
42 = 3 • t^2 ÷ 5 + 12; apply property of subtraction of equality
42 – 12 = 3t^2 ÷ 5 + 12 – 12; simplify
30 = 3t^2 ÷ 5; apply property of multiplication of equality
30 • 5 = 3t^2 ÷ 5 • 5; simplify
6 = 3t^2; apply property of division of equality
6 ÷ 3 = 3t^2 ÷ 3; simplify
2 = t^2
√2' = t
