Answer:
(a) 4
(b) 2/3
Step-by-step explanation:
(a) 4y+3=19
4y=19-3
4y=16
y=4
(b) 12n-3=5
12n=5+3
12n=8
n=8/12
n=2/3
Answer:
The value of x = 9
Step-by-step explanation:
∵ The figure has right angle and a line ⊥ from the right angle to the hypotenuse
∴ There is a relation between the ⊥ line and the two parts of the hypotenuse
∴ (⊥)² = multiplication of the two parts of the hypotenuse
∴ (6)²= 4 × x
∴ 36 = 4 × x
∴ x = 36/4 = 9
Answer:(2,1/3)
Step-by-step explanation:
-x-3y=-3
2x+3y=5
_________First solve for x since y is 0. -3y+3y=0
1X = 2
1x/1= 2/1
X= 2
Now substitute your x answer into any equation to find y I used second equation
2x+3y= 5
2(2)+3y=5
4+3y=5
3y=5-4
3y=1
3y/3=1/3
Y=1/3
Answer:
y=-x
Step-by-step explanation:
since the slope has a -1
a tree casts a 25-foot shadow on sunny day. If the angle of elevation from the tip of the shadow to the top of the tree is 32 degree, what is the height of the tree to the nearest tenth of a foot?
Tan(32)=H/25
0.624869=H/25
H=.624869 X 25
H=15.6 feet-Height of the tree.
