-10 - -8 = -10 + 8 = -2
-2
x + y = 10 y = x + 8 so, x + (x + 8) = 10 2x + 8 = 10 2x + 8 - 8 = 10 - 8 2x = 2 x = 1 and y = 9 because y = x + 8 y = 1 + 8 y = 9
3x actually means 3 * x.So we are going to follow BODMAS rule... 3x-5-10 =3*4-5-10 =12-5-10 =7-10 =-3 Here's your answer..
(3 * 3)(2 * 5) (9)(10) 90
2.42 * 10^ 8 m in 3 seconds = (2.42 / 3.00) * 10^8 m / sec =0.806667 * 10^8 m / sec = 8.06667 * 10^7 m / sec
Evaluate: -7 - 8
10
5 x 2= 10 10 x 8= 80 80/4= 20
You evaluate the powers of 10 and a exponent of positive 4.
Mutiply the digits and add the powers and so (4*10^4)(2*10^5) = 8*10^9
Evaluate means to "find the value" of. It is similar to the old question, "what is 10 plus 4?" Evaluate (10+4) should evoke the the same answer.
To evaluate 4.5 (-10), you need to multiply 4.5 by -10. The result of multiplying 4.5 by -10 is -45.

It is 8.
It is: 8+7 = 15
