Answer:
Step-by-step explanation:
Given
Required
The surface area
This is calculated as:
So:
-2y = 48 + 6x
-6x - 2y = 48 ——(1)
-6x + 9y = -84
-6x = -84 -9y ——(2)
Substitute (2) into (1):
(-84 -9y) -2y = 48
-84 -9y -2y = 48
-84 -11y = 48
-11y = 48 + 84
-11y = 132
y = - 12
Substitute y = -12 into (1):
-6x -2(-12) = 48
-6x + 24 = 48
-6x = 48 -24
-6x = 24
X = -4
ANS : y= -12, x= -4
T = 15.70r
time cost (t) = the price of the bag of rice • the number of bags of rice
Answer:
The expression that represents another method of computing
Is
615/100*(-311/100)
Step-by-step explanation:
Given the expression in decimal form, we can convert this to factional form and perform product operations as an alternative computational method
6.15*(-3.11)= 19.13
In fraction 6.15 can be written as
615/100
In fraction -3.11 can be written as
-311/100
Hence The product can also be expressed as fractions
615/100*(-311/100)
