Number 13
X=70 and y=125

Here we can find x by the property of linear pair
And y by angle sum property for parallelogram

Number 14

X=30

We can use angle sum property here

So 2x+3x+x=180
6x=180
X=180/6
X= 30

Hope it helps

Bill takes a loan of 9,000.00 at a 8% simple interrst rate for 6 years a.how much interest will he pay after 2 years? b. how muc

statuscvo [17]

To find the answer for A you add up the interest rate for 2 years which is 16% then find 16% of $9,000 which is $1,440 and that's his interest rate he will have to pay for 2 years. If you want to know how much he has to pay in total for 2 years you simply just add the interest rate $1,440to $9,000 and you get $10,440.

To find the answer for B you add up the interest rate for 6 years which is 48% then find 48% of $9,000 which is $4,320 and that's his interest rate he will have to pay for 6 years. If you want to know how much he has to pay in the total 6 years you simply just add the interest rate $4,320 to $9,000 and you get $13,320.

I hope that helped you.

Katie gives Maggie half of her pencils. Maggie keeps 5 pencils and gives the rest to Jamil. A. Write an expression for the numbe

Alexandra [31]

Here's what I mean when I write x/2 JUST IN CASE.

а.

Let the total number of pencils be x, then this implies that Maggie received x/2 pencils from Katie. Maggie keeps 5 and give the rest to Jamil, this means

that Jamil receives

x/2-5 pencils.

b. Expression of pencils given to Jamil is: x/2-5

Substitute x=16 in this expression: x/2-5

Simplify and evaluate: = 8-5= 3

Maggie gives 3 pencils to Jamil.

c. Expression of pencils given to Jamil is: x/2-5 to

Equate this expression with 1 to form an equation and solve for x all, the total

number of pencils if Jamil received 1 pencil:

x/2 - 5 = 1

Solve for x:

x = 2(1+ 5)

Evaluate:

x = 2(6) = 12

Katie had 12 pencils if Jamil received 1 pencil.

RESULT

a. Expression of number of pencils given to Jamil is x/2-5, where x is total number of pencils.

b. Maggie gives 3 pencils to Jamil.

c. Katie had 12 pencils if Jamil received 1 pencil.

Answer:

$\overline{BC} \cong \overline{DC}$ because corresponding parts of congruent triangles ΔACD and ΔACB are Congruent

Step-by-step explanation:

Statements, Reason

$\overline{AC}$ bisects ∠BCD, Given

$\overline{DC} \perp \overline{AD}$ Given

∠CDA ≅ ∠CBA Right angles are ≅

$\overline{AC} \cong \overline{AC}$ Reflexive property

ΔACD ≅ ΔACB Hypotenuse Leg (HL) congrurency

$\overline{BC} \cong \overline{DC}$ CPCTC

Where:

CPCTC = Corresponding parts of Congruent Triangles are Congruent

⊥ = Perpendicular to

≅ = Congruent

∠ = Angle

Δ = Triangle.
