8 0

B is related to the last term of trinomial

Last term on the left hand side of the equation = Last term on the right hand side of the equation.

The last term on the right hand side is gotten by multiplying all the terms on the right of the two expression.

-32y²= 2*-8y*By

-32y² = -16By² Compare both

32 = 16B

16B = 32

B = 32/16

B = 2.

The digits of a two-digit number differ by 2. If the digits are interchanged and the resulting number is added to the original n

butalik [34]

$x$ - tens digit

$y$ - units digit

$10x+y$ - the original number

$10y+x$ - the number with interchanged digits

$|x-y|=2\\10x+y+10y+x=110\\\\x-y=2 \vee x-y=-2\\11x+11y=110\\\\x=y+2 \vee x=y-2\\x+y=10\\\\y+2+y=10 \vee y-2+y=10\\2y=8 \vee 2x=12\\y=4 \vee y=6\\\\x+4=10 \vee x+6=10\\x=6 \vee x=4$

$10x+y=10\cdot 6+4 \vee 10x+y=10\cdot4+6\\10x+y=64 \vee 10x+y=46$

Therefore, the original number can be either 46 or 64.

What is the value of x?

lina2011 [118]

Answer : The value of x is 5.

Step-by-step explanation :

According to the angle bisector theorem, an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.

That means,

$\frac{AB}{BD}=\frac{AC}{CD}$

$\frac{9}{2x-1}=\frac{15}{3x}$

By the cross multiplication, we get:

$9\times 3x=(2x-1)\times 15$

$27x=30x-15$

$30x-27x=15$

$3x=15$

$x=\frac{15}{3}$

$x=5$

Therefore, the value of x is 5.

Solve each equation for y. 3x + 2 =6y

Strike441 [17]

Answer:

1/2x + 1/3 = y

Step-by-step explanation:

3x + 2 =6y

Divide each side by 6

3x/6 + 2/6 = 6y/6

Simplify

1/2x + 1/3 = y

1-Jace receives a shipment of 700 oranges.He randomly selects 25 oranges to weigh.In that sample, 2 oranges weigh 5 ounces.How m

Nat2105 [25]

Answer: 56 oranges

Step-by-step explanation:

In a sample of 25 oranges, 2 oranges weigh 5 ounces.

Proportionally represented, that would be:

= 2 / 25

Assuming the 25 is representative for all 700 oranges, the number of oranges that can be expected to weigh 5 ounces from the shipment is:

= Proportion of 5 ounces oranges from sample * Total number of oranges

= 2/25 * 700

= 56 oranges

Triangle hjk is an isosceles triangle. The measures of angles j and k are equal. The measure of angle h is 100 degrees. How do y

WITCHER [35]

Every triangle has a total of 180 degrees. If one angle measure is 100, then 180-100 is 80. This means that the other two angle measures have a total of 80. As angle j and k are equal, we divide 80 by 2, to get 40. This means that the measure of both angle j and k is 40 degrees. The measure of angle j is 40 degrees.
