Answer) A
Explanation) 6:7 is equal to 36:42 because you can multiply both 6 and 7 by 6 to get 36:42.
Answer:
The answer is that z = 3
Step-by-step explanation:
Once you solve you get z = 3
-8z + 12 = -12 you subtract -12 from both sides to get rid of the positive 12
-12 = -12
__________
-8z = -24
__ __ divide -8 both sides
-8 -8 two negatives equal a positive
z = 3
Answer:
(x, y) = ( -4 , 4)
Step-by-step explanation:
STep 1: substitute the given value of x into the equation -7 x - 6y = 4 which will be -7 (-3 y + 8) - 6 y = 4
STEP 2: solve the equation for y so basically -7 (-3 y + 8) - 6 y will be y = 4
STEP 3:substitute the given value of x into the equation so y = 4 would be
x = -3 x 4 + 8
STEP 4: solve the equation for x. -3 x 4 + 8 which you'd end up with x = -4
1.) 3 + 2 x 10 = 3 + 20 = 23
2.) 2(1-4)^2 = 2(-3^2) = 2(9) = 18
3.) -3^2 + 3^2 = 9 + 9 = 18
4.) 8 - [(4-7) + (8-1)] = 8 - [-3 + 7] = 8 - 4 = 4
5.) 4 - {8 - (2-4)} = 4 - {8 - (-2)} = 4 - {8 + 2} = 4 - 10 = -6
