Answer:
the answer is D
Step-by-step explanation:
times 26 by 30 then times the product by 4 since a trinaglar pyramid has four sides
Answer:
Both are 55
Step-by-step explanation:
To solve this problem, set the equations equal to each other, solve for n, then plug in the values
Solve for n:
1. 2n+15=3n-5
2. Add 5 to both sides
3. Now you have 2n+20=3n
4. Subtract 2n from both sides
5. You are left with n=20
Next, plug it in:
1. Replace all n's with 20
2. 2(20)+15=55
3. 3(20)-5=55
There you go! Hope this helps!
Answer:
x ≤ 13/3
Step-by-step explanation:
4 - 3x ≥ -9
Isolate the variable, x. Treat the ≥ sign as an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 4 from both side:
4 (-4) - 3x ≥ -9 (-4)
-3x ≥ - 9 - 4
-3x ≥ -13
Next, divide -3 from both sides. Note that when you divide by a negative sign, you must flip the sign:
(-3x)/-3 ≥ (-13)/-3
x ≤ (-13)/(-3)
x ≤ 13/3
x ≤ 13/3 is your answer.
