Y=_x+4<br> x + 2y =<br> 8<br> How many solutions dose this linear system have
jeyben [28]

Answer:

X=-1, y=4

Step-by-step explanation:

y = x + 4 \\ x + 2y = 8 \\  =  =  =  =  =  =  =  =  =  =  =  = \\ y - x = 4 \\ x + 2y = 8

by using eliminating property

3y = 12 \\ y = \frac{12}{3}    = 4

by substitution

X=-1

17. The Bricklayer needs 100 pieces of angle, each to be cut 54 3/16" long. 1 point
mariarad [96]

The number of cuts from a 20% length is 2 and the number of 20' angle are needed in order to have the 100 pieces is 5

<h3>How to determine the number</h3>

From the information given;

The bricklayer needs = 100 pieces of angle

The number of cuts = 54

Length of cuts = 3/ 16'' Inches

a. To determine the number of cuts form a 20% length, we have to multiply the length by the percentage and by the initial number of cuts

= 20/ 100 × 3/ 16 × 54

= 0. 2 × 0. 1875 × 54

= 2. 0

The number of cuts would be 2

b. To determine the number of pieces of 20' angle to have 100 pieces we would divide the initial number of pieces by the angle

= 100/ 20

= 5 pieces

The number of pieces of 20' angle is 5

Thus, the number of cuts from a 20% length is 2 and the number of 20' angle are needed in order to have the 100 pieces is 5
