X=4.2
For the second equation, y=4x-25. Then you plug that into the first equation, which would form: 2x+2(4x-25)=17. Simplify. 2x+8x-25=17. 10x=42. x=4.2

Answer:

6.7 is the value of x.

Step-by-step explanation:

Given equations are

2x+2y=17     eq(1)

4x-y=25        eq(2)

from eq(2), we get

-y=25-4x

multiplying by -1 to above equation, we get

y=-25+4x

y=4x-25

subtitute above value of y in eq(1), we get

2x+2(4x-25)=17

2x+8x-50=17

add 50 on both sides of above equation, we get

2x+8x-50+50=17+50

2x+8x+0=17+50

2x+8x=17+50

add like terms

10x=67

dividing by 10 on both sides of above equation, we get

10x/10=67/10

x=67/10=6.7 which is the answer.

Patrick is constructing the circumscribed circle for △RST. Which construction could be his first step?
Naya [18.7K]
Steps in constructing a circumscribed circle on a triangle using a just a compass and a straight edge.
1) construct a perpendicular bisector of one side of ΔRST.
2) construct another perpendicular bisector of another side of ΔRST
3) the point where the two bisectors intersect will be the center of the circle.
4) place the compass on the center point, adjust its length to ensure that any corner of the triangle will be reached and draw the circumscribed circle.

The top of a table is a parallelogram with a base of 28 cm and a height of 20 cm. Patty wants to cover the table with tiles that
suter [353]

The area of the top of the table is 28 × 20 = 560 cm2. The area of Patty’s tiles is 8 cm2 each and the area of Jake’s tiles is 9 cm2 each. Patty will need 560 ÷ 8, or 70, tiles. Jake will need 560 ÷ 9, or about 63, tiles. So, Patty will use about 7 more tiles.
