Answer:
<h2>128</h2>
Step-by-step explanation:
Step one:
given the expression w/8 - 4 = 20
the first operation is to isolate the term that has w by adding 4 to both sides
w/8 - 4+4 = 20+4
w/8 = 16
Required
the value of w
Step two:
the next step is to cross multiply
w=16*8
w=128
Answer:
Y=109 X=31
Step-by-step explanation:
Alright, so the angles that you have to find the values for make up 180 degrees. Since you have 71 degrees on the bottom, and according to a certain theorem I forgot about, that means that the angles you're solving for equal 109 degrees.
X= 31 because 4 x 31 = 124 and then 124 - 15 equals 109
If x=-4, that means that since we have x² at x≤-4, it encompasses -4 (due to the line at the bottom). (-4)²=16. For 4, since 4>1 and it's √x if x is over 1, √4=2
Answer: y = -9/14
Step-by-step explanation: Let's solve your equation step-by-step.
7/3y + 2 = 1/2
Step 1: Subtract 2 from both sides.
7/3y + 2 - 2 = 1/2 - 2
7/3y = -3/2
Step 2: Multiply both sides by 3/7.
(3/7) x (7/3y) = (3/7) x (-3/2)
y = -9/14
