The sum of three numbers is 24. Twice the middle number is 2 more than the largest number, and the largest number is equal to th

harina [27]

Answer:

x = 5, y = 7, z = 12

Step-by-step explanation:

Let the numbers be x, y and z

x + y + z = 24
2y = z + 2
z = x + y

Solving by substitution:

x + y + z = z + z = 24
2z = 24
z = 12

2y = z + 2
2y = 12 + 2
2y = 14
y = 7

z = x + y
x = z - y
x = 12 - 7 = 5

The answer:

x = 5, y = 7, z = 12

Select the best attribute for the angle pair formed by two parallel lines intersected

Inga [223]

Answer:

Corresponding Angles sum to 180°

Step-by-step explanation:

If a pair of parallel lines is cut by transversal that is not perpendicular to the parallel lines as shwon in the figures (attached below), then;

Four angles are acute, and four are obtuse.

All four acute angles are equal: 2=3=6=7
All four obtuse angles are equal: 1=4=5=8
The sum of acute and obtuse angles is 180: for example, 1+2=180, 3+4=180, 5+6=180, 7+8=180

so the best attribute for the angle pair formed by two parallel lines intersected by a transversal is that Corresponding Angles sum to 180°.

1/3y+11=1/2y-3 What is y???

olga55 [171]

Answer:

$y=84$

Step-by-step explanation:

$\left(\frac{1}{3}\right)y+11=\left(\frac{1}{2}\right)y-3$

Use distributive property.

$\frac{1}{3}y+11=\frac{1}{2}y-3$

$\frac{1}{3}y+11-11=\frac{1}{2}y-3-11$

$\frac{1}{3}y=\frac{1}{2}y-14$

$\frac{1}{3}y-\frac{1}{2}y=\frac{1}{2}y-14-\frac{1}{2}y$

$-\frac{1}{6}y=-14$

$\left(-\frac{1}{6}y\right)\left(-6\right)=\left(-14\right)\left(-6\right)$

$y=84$

Write a recursive formula for the explicit formula.

Setler79 [48]

Answer: A

Step-by-step explanation:

$A_n=9+(n-1)*(-4)\\\\A_1=9+(1-1)*(-1)=9+0=9\\\\A_{n-1}=9+((n-1)-1)*(-4)\\\\A_n-A_{n-1}=9+(n-1)*(-4)-(9+(n-2)*(-4))=-4n+4+4n-8=-4\\\\\boxed{A_n=A_{n-1}-4}\\\\\\Answer\ A$
