Answer: y−3=−3y−43

Step 1: Add 3y to both sides.

y−3+3y=−3y−43+3y

4y−3=−43

Step 2: Add 3 to both sides.

4y−3+3=−43+3

4y=−40

Step 3: Divide both sides by 4.

4y

liq [111]

Answer:

Part A

it supposed to be x⩾-1/3 since you divided by negative

Step-by-step explanation:

Part A

4-6x⩾-15x+1

step 1: add -6x to both sides

4-6x+6x⩾-15x+6x+1

=4⩾-9x+1

step 2: subtract 1 from both sides

4-1⩾-9x+1-1

3⩾-9x

step 3: do reflexive property and divide

3⩾-9x

= <u>-9x⩽3</u>

-9

x⩽-1/3

and since you divided by negative, the sign must change. so it'll be x⩾-1/3

Find the surface area of the figure shown. 5 cm 5 cm cm 1.5 cm 8 cm your answer​
Delicious77 [7]

Answer:

51 cm^2

Step-by-step explanation:

the formula for area of an icoselese triangle is
A = b * h / 2
h is a line from the angle where the 5 and 5 intersect to the middle of the third line
You can find h using the pythagoran theorm with the 5 being the hypotenuse and the a being half the third line

4^2 + b^2 = 5^2
16 + b^2 = 25
b = 3, so h = 3, so now
A = 8 * 3 / 2
A = 24 / 2
A = 12 cm^2

now we have the triangle, just multiply that by 2 (top and bottom)
12 * 2 = 24

sides
8 * 1.5 = 12
5 * 1.5 * 2 = 15

now add all of it
15 + 12 + 24 = 51
