Answer: (-6,-5)
Step-by-step explanation:
2x - 2y = -2 ............ equation 1
3x - y = -13 ................ equation 2
solving by substitution method
from equation 2 , make y the subject of the formula, we have
y = 3x + 13 .............. equation 3
substitute equation 3 into equation 1 , we have
2x - 2 (3x + 13 ) = -2
2x - 6x - 26 = -2
-4x - 26 = -2
-4x = -2 +26
-4x = 24
x = 24/-4
x = -6
substitute x = -6 into equation 3 to get the value of y , we have
y = 3(-6) + 13
y = -18 +13
y = -5
<span>0.4×0.4×0.4 is equal to 0.4 to the third power, or 0.4</span>³
To convert to exponential form, count how many times the number is multiplied by itself and make that number the exponent. In this case, the 0.4 is multiplied by itself 3 times, so our exponent is 3.
Answer is 0.4³
Answer:
6,372
Step-by-step explanation:
The ratio is 59:1, meaning the new ratio is ?:108
To find the value you're searching for, multiply 108 by 59
108*59=6,372
To check your work you can divide both sides by 108 and if it is correct you should get the ratio 59:1, let's see
6,372/108=59
108/108=1
59:1... we have the right answer!
