You can do 15-5=10 and then you have 3 left to subtract. Which means 10-3=7
X should be 3,
because 8x means 8 times what number.
So 8x must be 3.
8 times 3 = 24. 24 +5 = 29.
Hope you Understand :) !
Answer:
6. x = 28 degrees
7. z = 1.6 cm
Step-by-step explanation:
6.
Notice that you can use the property that tells us that the addition of all internal angles of a triangle must give 180 degrees, then you write the following equation:
50 + 69 + (2 x +5) = 180
combine like terms:
119 + 2 x + 5 = 180
124 + 2 x = 180
subtract 124 from both sides:
2 x = 56
divide by 2 both sides:
x = 56 / 2
x = 28 degrees
Problem 7.
If the two triangles are congruent, then the side MN must equal side RS.
Since MN measure 1,8 cm, then RS must also measure 1.8 cm
and we can write the equation:
1.8 = 3 z - 3
adding 3 to both sides:
1.8 + 3 = 3 z
4.8 = 3 z
dividing both sides by 3:
z = 4.8 / 3
z = 1.6 cm
Answer:No it's not an exponential equation in which f(x)is not qualified to an exponential number. no number from 1 - 20 can be used and get subtracted by 2 to give a square number.
eg-
4×2-2≠ square number
Step-by-step explanation:
Answer:
x-2=x x=0
No Solution
x+1=1-x
Cancel
1 on both sides
Subtract
−x from both sides
x+x=0
Simplify x
+x to 2x
2x=0
x=0
Check Answer
x+1=1-x
0+1=1-0
1=1-0
1=1
