Answer:
in the forth line of the equation it should be this
-6x+10=4x+20
-6x-4x=20-10
-10/-10x=10/-10
x=-1
The number that equals 280 tenths + 19 thousandths is 28.019
<h3>How to determine the number?</h3>
The statement is given as:
280 tenths + 19 thousandths
Rewrite the terms of the expression as fractions
So, we have
280/10 + 19/1000
Evaluate the quotients
28.0 + 0.019
Add both numbers
28.019
Hence, the number that equals 280 tenths + 19 thousandths is 28.019

Step-by-step explanation:
Step-by-step explanation:
Explanation:
Given:
−3x2+12x+1=0
This is in the form:
ax2+bx+c=0
with a=−3, b=12 and c=1
In order to decide which method to use, we can first examine the discriminant:
Δ=b2−4ac=122−4(−3)(1)=144+12=156
Since Δ>0 we can tell that the quadratic has 2 distinct real solutions, but because it is not a perfect square we can also tell that those solutions are irrational.
So there is no rational factorisation and we can discount the use of an AC method or similar.
We can use the quadratic formula or we can complete the square.
If we choose to use the quadratic formula, then we find:
x=−b±√b2−4ac2a
x=−b±√Δ2a
x=−(12)±√1562(−3)
x=−12±2√39−6
x=2±√393
When completing the square, note that b=12 is already divisible by a=−3 and by
There will be 73 apples in each basket,
to solve this you divide 219 into three.
Hope this helped!!
