Answer:

Step-by-step explanation:

andi +10 = charley

and in 4 years

2*andi = charley +4

so

2*andi -4 = charley

now since we have  charley as the indepentdent on each equation

set those parts equal to each other

andi + 10 = 2*andi -4

and + 14 = 2*andi

14 = andi

so andi is 14

charley is 24

Answer:

m\angle AED=90\degree

m\angle DAE=53\degree

m\angle BCE= 53\degree

Step-by-step explanation:

ABCD is a rhombus. AC and BD are its diagonals intersecting at point E.

Diagonals of a rhombus bisects at right angles.

\therefore m\angle AED=90\degree

In\: \triangle AED

m\angle DAE=90\degree-m\angle EDA

m\angle DAE=90\degree-37\degree

m\angle DAE=53\degree

\because m\angle BCE= m\angle DAE

(Alternate angles)

\therefore m\angle BCE= 53\degree

Ivan has 4 hours of music on his mp3player. Jazz makes up 1/6 of the total time . How many hours of jazz are in Ivan MP3 player
Irina-Kira [14]
So he has 4 hrs on his mp3 player...for which jazz makes up 1/6 of it..

so we need 1/6 of 4 hrs...." of " means multiply
1/6 * 4 = 4/6 = 2/3 of an hr <==

Match each polynomial function with its leading coefficient.
stiv31 [10]

The correct match for each leading coefficient will be as below:-

1.  ⇒ b ⇒ 8

2. ⇒ d ⇒ 4

3. ⇒ e ⇒ 40

4. ⇒ c ⇒ - 8

5. ⇒ a ⇒  2

<h3>What is a polynomial?</h3>

A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.

The leading coefficient of the polynomial is defined as the coefficient of the variable having the highest power in the polynomial.

For the given polynomials calculate the highest power variable in each polynomial with the coefficient.

1.

P(x) = (x + 2) (2x - 3) (4x +7):

P(x) = 8x³

2.

P(x) = 1/2(x - 2) (2x - 3) (4x + 7):

P(x) = 4x³

3.

P(x)= 5(x - 2) (2x - 3) (4x + 7):

P(x)= 40x³

4.

P(x) = -(x - 2) (2x - 3) (4x + 7):

P(x) = -8x³

5.

P(x) = 1/4(X + 2) (2x - 3) (4x + 7):

P(x) = 2x³

Therefore, the leading coefficients are 8, 4, 40, -8, and 2 respectively.
