3 0

Answer:

5\frac{1}{4}

Step-by-step explanation:

Greatest multiplier of 4 that is less than 21 is 5 (4 x 5 = 20)

Put the remaining number as the numerator (21 - 20 = 1)

x,y, and z to the nearest tenth .(hint: use altitude and leg rules) PLEASE HELP FAST !!! please solve and show steps
madreJ [45]

Use the Pythagorean theorem to find z:

z = √(6^2 + 9^2)

z= √(36 + 81)

z = √117

z = 3√13 = 10.8

Use leg rule to find x:

x/6 = 6/9

Cross multiply:

9x = 36

Divide both sides by 9:

x = 36/9

x = 4

Use Pythagorean theorem to find y:

y = √(6^2 + 4^2)

y= √(36 + 16)

y = √52

y = 2√13 = 7.2

PLEASE HELP!!<br> Convert each linear equation to standard form.<br> y-4= -2(x+3)
hjlf
So first, this is point slope form. The first step is to distribute.)
y-4=-2x-6
Then add 4 to both sides.
y=-2x-2
Then add 2x and it becomes
2x+y=-2
