Answer:
Step-by-step explanation:
Since Ray AB is the angle bisector of ∠CAD,
∠CAB = ∠BAD
5*x - 17 = 3*x + 13
x = 15°
Answer:
gradient = -10
y intercept = 1
Step-by-step explanation:
y = mx + b
y = -10x + 1
m = slope ; hence, slope = -10 in the eqn
y intercept = when x = 0
y = -10(0) + 1
y = 1
Answer:
48
Step-by-step explanation:
3(22)+4(32)
=(3)(4)+4(32)
=12+4(32)
=12+(4)(9)
=12+36
=48
Answer:
Step-by-step explanation:
Assume the base is right triangle.
<u>The volume:</u>
<u>Substitute values and solve for h:</u>
- 154 = 1/2(7)(4)h
- 154 = 14h
- h = 154/14
- h = 11 inches
First to answer
Answer:
A. The coefficients of z are the same, but the constant terms are different.
Step By step Explanation:
2(z – 1) = 4(z + 5)
Step 1: Simplify both sides of the equation.
2(z−1)=4(z+5)
(2)(z)+(2)(−1)=(4)(z)+(4)(5)(Distribute)
2z+−2=4z+20
2z−2=4z+20
Step 2: Subtract 4z from both sides.
2z−2−4z=4z+20−4z
−2z−2=20
Step 3: Add 2 to both sides.
−2z−2+2=20+2
−2z=22
Step 4: Divide both sides by -2.
−2z/−2 = 22/−2
z=−11
The coefficients for z are the same, but the constants are different.
