Answer:

m=10

Step-by-step explanation:

9(m+5)−3(m−2)=8m+31

Step 1: Simplify both sides of the equation.

9(m+5)−3(m−2)=8m+31

9m+45+−3m+6=8m+31

(9m+−3m)+(45+6)=8m+31(Combine Like Terms)

6m+51=8m+31

Step 2: Subtract 8m from both sides.

6m+51−8m=8m+31−8m

−2m+51=31

Step 3: Subtract 51 from both sides.

−2m+51−51=31−51

−2m=−20

Step 4: Divide both sides by -2.

m=10

Hope this helps girly!!

What is the least common denominator of 4/x * -4/2x^2?
Vanyuwa [196]
The least common denominator would be 2x^2
that is because you would have to multiply the first fraction by 2x
but you can't just somehow simplify 2x^2, it wouldn't be right
4/x * -4/2x^2
2x*4/(2x*x) * -4/2x^2
8x /2x^2 * -4/2x^2
Then you would complete it 

Hope this helps :)

Step-by-step explanation:

I think you mean triangle XYZ. and angle XYZ.

so, the angle at Y is 90°.

that makes XZ the Hypotenuse (baseline opposite of the 90° angle) of the right-angled triangle.

so, we can actually use Pythagoras (we don't need the area of the triangle to solve) :

13² = 12² + YZ²

169 = 144 + YZ²

25 = YZ²

YZ = 5 cm

just to check - the area of this triangle is (remember, it is a right-angled triangle, so XY and YZ serve also as baseline and height) :

area = 12 × 5 / 2 = 60/2 = 30 cm²

correct, it fits.

A doctor orders 20 grams of a 52% solution of a certain medicine. The pharmacist has only bottles of 40% solution and bottles of
Anvisha [2.4K]
Try, please, this:
1) Imagine, that pharmacist used 'x' gr. of 40% solution and 'y' of 70% solution.
Together (20 gr. of 52% sol.) it will be x+y=20.
2) From other side, the pharmacist combined 40x and 70y gramms, after obtaining together it is 52(x+y) gramms. In other words 40x+70y=52(x+y)
3) 
\left \{ {{x+y=20} \atop {40x+70y=52(x+y)}} \right. \ =\ \textgreater \  \  \left \{ {{y=8} \atop {x=12}} \right.
Answer: 8 gr. of 70% solution and 12 gr. of 40%.
