Answer:
Step-by-step explanation:
4 feet = 48 inches, add 10 inches = 58 inches
if susan is 15 inches shorter, 58- 15 = 43
43/12 = 3 feet 5 inches
Answer:
The point of intersection is (6,3)
Hi
Here is the Justification
Line 1 : 3p-(p+8) = 5p-7 [Given]
Line 2: 3p-p-8=5p-7 [ Applying distributive property]
Line 3: 2p-8=5p-7 [Simplifying like terms]
Line 4: -8=3p-7 [Subtraction property]
Line 5 -1=3p [Additive property](Add 7 on both sides]
Line 6 -1/3=p [Multiplicative inverse or division]
Line 7 p=-1/3 [Property of equality]
Thank you.
Angle z makes a 180° angle when added to the angle of 124° in the first image, because they are on the same side of a straight line. Just subtract 124 from 180. =56
For the second picture, angle m will be the same as angle z because of the properties involved. Find angle z using the same thought process as above, and m will equal it. =55
The sum of the angles in a triangle is 180°, that's just a property they have. You add the two angles you know, subtract them from 180, and you have x. =47

Using these variables, we can set up equations.
3x + 5y = 42
9x + 7y = 72
We have here a system of equations, where we have two or more equations with two or more different variables. We use the elimination method to solve for the variables.
Multiply eq1 by 3. Keep eq2.
9x + 15y = 126 eq1
9x + 7y = 72 eq2
Subtract eq2 from eq1 to eliminate the x terms.
8y = 54
y = 6.75
