Answer:
x=12 ADB= 56 BDC= 54
Step-by-step explanation:
ADB and BDC are complementary, so they add up to 90 degrees. In other words ADB+BDC= 90 So I can input my knowns into the equation
(3x+10) + (4x-4) = 90
I combined like terms to give me 7x+6=90
Then I subtract 6 from both sides giving me 7x=84
Last I divide 7 on both sides. x=12
Then I input the x (12) into the equation and solve it from there
3(12)+10 and 4(12)-4
3(12)+10=56
4(12)-4=54
. . . I think. Hope this helps!
Answer:
69920
Step-by-step explanation:
If you are without a calculator, there is a trick you can do that could make this easier for you.
Instead of multiplying by 95 right away, instead, try multiplying by 100.
736 x 100 = 73600
With that, subtract by the product of 736 x 5 (which equals 3680)
With this, we can use what we know to say that
736x95 = 736x100 - 736x5; plug in what we got as our products and we're given
736x95 = 73600 - 3680 = 69920
It is 62.54
Hope this helped.
Answer:
Look below
Step-by-step explanation:
9 would be a solution of the inequality x>5 because x can represent any number, but because there is a > between x and 5, that means that whatever number x represents is greater than 5, and because 9 is greater than 5, it is a solution to the inequality.
Hope this helps :)
