Answer:
UW ≈ 6.55 ≈ 7
Step-by-step explanation:
cos (35) = adjacent/hypotenuse
cos(35) = UW/VW
cos(35) = UW/8
8*cos(35) = UW
UW ≈ 6.55

Step-by-step explanation:
<u>Step 1: Define</u>
-4p + 9 = -5
<u>Step 2: Solve for </u><em><u>p</u></em>
- Subtract 9 on both sides: -4p = -14
- Divide -4 on both sides: p = 7/2
<u>Step 3: Check</u>
<em>Plug in p into the original equation to verify it's a solution.</em>
- Substitute in <em>p</em>: -4(7/2) + 9 = -5
- Multiply: -14 + 9 = -5
- Add: -5 = -5
Here we see that -5 does indeed equal -5.
∴ p = 7/2 is the solution to the equation.
distance = speed x time
distance = 2.35 x time
distance = 2.35 x 5
distance = 11.75 feet in 5 minutes
To evaluate this, plug in the number 4 for the variable a and the number 5 for the variable 5.
6a + 3ab
6(4) + 3(4)(5)
To solve this multiply then add.
Multiply from left to right and don't add until everything has been multiplied.
Basically, 6(4) + 3(4)(5) = (6 • 4) + (3 • 4 • 5).
6 • 4 = 24
3 • 4 = 12
12 • 5 = 60
Now we have 24 + 60.
Just add and you have your answer!
24 + 60 = 84
So when a is 4 and b is 5, <span>6a + 3ab is equal to 84.
Hope this helps!</span>
