Answer:
5
Step-by-step explanation:
2+3=5
Answer:
x = 16 and y = 121
Yes, its a long process.
Step-by-step explanation:
vertical angles are congruent given that: we do this
(4x-5)+(4x-5)+y+y=360
or
2(4x-5)+2y=360
divide both sides by 2
(4x-5)+y=180
distribute (there is an invisible 1 beside the parentheses of 4x-5)
4x-5+y=180
add 5 to both sides
4x+y = 185
subtract y from both sides
4x = 185-y
divide both sides by 4
x = (185-y)/4
note that (4x-5) is also EQUAL to (3x+11)
4x-5=3x+11
subtract 3x from both sides
x-5=11
add 5 to both sides
x = 16
Now that we know what x is, we can substitute it in the equation we got from 2(4x-5)+2y=360
Our equation was
x = (185-y)/4
16 = (185-y)/4
Multiply both sides by 4
64 = 185-y
Subtract 185 from both sides
-121=-y
multiply both sides by -1
121 = y
Answer:
B. 195.5 kg
Step-by-step explanation:
Given
Weight in pounds = 430 pounds
1 kilogram = 2.2 pounds
Required
The weight in kilogram
Let x represents the weight of the humpback's whale's heart in kilogram
Such that;
By Cross multiplication
Divide both sides by 2.2lb
Approximate
Hence, the weight of the heart is 195.5kg
Answer:
x = -1
Step-by-step explanation:
since the 23 is positive you have to subtract it on both sides . which would give you -4x =4
then divide -4 on each side and you should get x = -1
a positive divided by a negative is always negative.
The answer is A. Heterotrophic
