Answer:
x=71
Step-by-step explanation:
Since this is an isosceles triangle the bottom 2 angles are equal.
The three angles of the triangle are x, x, and 38. They must add to 180 degrees
x+x+38 = 180
Combine like terms
2x+38=180
Subtract 38 from each side
2x+38-38 = 180-38
2x = 142
Divide each side by 2
2x/2 =142/2
x =71
Answer:
yes
Step-by-step explanation:
They are correct because the reciprocal ( flipped or opposite) of -2/5 is 5/-2
Answer:
x = 15
Step-by-step explanation:
Given
2 = - 
+ 
x
Multiply through by 4 to clear the fractions
8 = - 7 + x ( add 7 to both sides )
15 = x
Answer:
Step-by-step explanation:
We want to simplify;
We expand the bracket to obtain;

The correct answer is C
Answer:
If 9 liters 400 millitres of water is further added, there will be 20 liters of water in the tub.
Step-by-step explanation:
Given that a tub contains 10 liters 600 millitres of water, to determine, if 9 liters 400 millitres of water is further added to this, what will be total water in the tub, the following calculation must be performed:
1 liter = 1000 milliliters
0.6 liters = 600 milliliters
10.6 + 9.4 = X
20 = X
Therefore, if 9 liters 400 millitres of water is further added, there will be 20 liters of water in the tub.
