Answer:

1) 4

2) y <= 9

3) NO SOLUTION

4) 24

5) 5 cards

Step-by-step explanation:

1st pic) 2x + 7 = 15

2x + 7 = 15

<u>       -7    -7</u>

2x = 8

divide by 2 to isolate x

<u>x = 4</u>

2nd pic) y - 3 <= 6

y - 3 <= 6

<u>   +3      +3</u>

<u>y <= 9</u>

<u />

3rd pic) x + 0.5 = x + 6

x + 0.5 = x + 6

<u>    -0.5         -0.5</u>

x = x + 5.5

NO SOLUTION

4th pic)  5m + 10 <= 130

5m + 10 <= 130

<u>       -10        -10</u>

5m <= 120

divide by 5 to isolate the m

<u>m <= 24</u>

5th pic) 2c - 8 > 0

2c - 8 > 0

<u>      +8   +8</u>

2c > 8

divide by 2 to isolate the c

<u>c > 4</u>

Answer:

x = 4

Step-by-step explanation:

To solve, simplify the expression then use inverse operations to isolate x.

x - 4 = 0^2\\x-4 = 0\\x-4+4=0+4\\x = 4

HELP ASAP!!!!<br> GIVING BRAINLIEST!<br><br> Find the value of x and y with the steps PLEASE.
PtichkaEL [24]

Answer:

x=70

y= 40

Step-by-step explanation:

the triangle containing x is an isosceles triangle so two of the sides are 55.

55+55+x=180.

110+x=180

110-110+x=180-110

x=70

Triangle BAC is equilateral so 180/3=60. Now

x+60+c=180

70+60+c=180

130+c=180

130-130+c=180-130

c=50

That gives us one corner of triangle CBD. We know a second angle is 90 so

50+90+y=180

140+y=180

140-140+y=180-140

y=40

I think that is correct but you are free to check it yourself
