Let's evaluate left side first.
There are 4 -5's and 5 -3's
So that's 4(-5) + 5(-3) = -35
So now our equation is -35 = -5x
Now divide both sides by -5:
-35 / -5 = x
7 = x
So the missing number would be 7 to make this equation true.
Final answer: 7
Hope this helps.
Answer:
3y(2x - 5y).
Step-by-step explanation:
6xy is basically 2 * 3 * x * y.
-15y^2 is basically -1 * 3 * 5 * y * y.
Something both have in common are a 3 and a y.
So, we have...
3 * y(2 * x - 1 * 5 *y)
= 3y(2x - 5y).
Hope this helps!
This means that for every 10 of whatever measurement of sugar there will be 3 of that measurement of flour
70 oz of sugar / 10 = 7
3 (ratio of flour) times 7 = 21
21
The correct answwere is that he has $14.13 left
Answer:
X2+8X+6=0
We add all the numbers together, and all the variables
X^2+8X+6=0
a = 1; b = 8; c = +6;
Δ = b2-4ac
Δ = 82-4·1·6
Δ = 40
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
X1=−b−Δ√2aX2=−b+Δ√2a
The end solution:
Δ−−√=40−−√=4∗10−−−−−√=4√∗10−−√=210−−√
X1=−b−Δ√2a=−(8)−210√2∗1=−8−210√2
X2=−b+Δ√2a=−(8)+210√2∗1=−8+210√2
Step-by-step explanation:
