Answer:
a-3b+4
Step-by-step explanation:
a-3b+4
just divide 2a-6b+8 with 2
The second one. Do the math. .35 x 63 = 22.05
20%=20/100
(20/100)*50= 10 pages
Answer:
15 pizzas
Step-by-step explanation:
1 pizza serves 4 students
60 students divided by 4 students (which is 1 pizza)
60/4=15
Answer:
Given: △ABC, m∠B=90° AB=12, BC=16, BK ⊥ AC . Find: AC and BK.
Given: △ABC, m∠B=90°
Find: AC and BK.
Short leg 90 degrees Long leg Hypotenuse
AB=12 90 BC=16 AC= ?
AK = ? 90 BK = ? AB=12
AC = SQRT (AB*AB + BC*BC) = 20 [right triangle; Pythagorean Theorem]
Similar triangles:[Note: In diagram, share two angles. Therefore share three angles]
BK / 16 = AB / AC
BK / 16 = 12 / 20
BK = (3/5)16
BK = 48/5
another answer let see this
AB^2+BC^2=AC^2
12^2+16^2=AC^2
144+256=AC^2
400=AC^2
20=AC
