Answer:

7) x = 2

8) x = 3

9) x = -7

10) x = 8

Step-by-step explanation:

9x + 12 = 5x + 20

4x = 8

x = 2

2x + 12 = 6x

4x = 12

x = 3

62 + x + 125 = 180

x = -7

10)

arc WX = 2(35) = 70 degrees

12x + 14 + 70 = 180 degrees

12x = 96 degrees

x = 8

Serga [27]

Answer:

Length of beads altogether in the necklace = 3.75 cm

Step-by-step explanation:

Length of the beads used in a necklace = $\frac{5}{4}$ cm

Number of beads used in the necklace = 3

Therefore, length of beads in the necklace = Length of each bead × Number of beads used

= $\frac{5}{4}\times 3$

= $\frac{15}{4}$

= 3.75 cm

Length of the beads altogether in the necklace = 3.75 cm

Jada was using square stickers with a side length of 3/434 inch to decorate the spine of a photo album. The spine is 10 1/21012

Yuki888 [10]

Answer: The number of stickers she used to cover the length of the spine = 14.

Step-by-step explanation:

Given: The length of spine = $10\dfrac12$ inches = $\dfrac{21}{2}$ inches

Length of each sticker = $\dfrac34$ inch

If she laid the stickers side by side without gaps or overlaps, the number of stickers she use to cover the length of the spine = $\text{(Length of spine)}\div (\text{Length of each sticker})$

$=\dfrac{21}{2}\div\dfrac{3}{4}\\\\=\dfrac{21}{2}\times\dfrac{4}{3}\\\\=\dfrac{7\times2}{1}=14$

The number of stickers she used to cover the length of the spine = 14.

Y = 4x - 6

Studentka2010 [4]

Answer:

B) 2x - 12x - 18 = 8

Step-by-step explanation:

2x - 3y = 8

If y = 4x - 6, then substitute and solve:

2x - 3(4x - 6) = 8

2x - 12x - 18 = 8

10x - 18 = 8

10x = 8 + 18

10x = 26

x = 26/10

x = 2.6

y = 4(2.6) - 6

y = 10.4 - 6

y = 4.4
